How much feed does the pig feed one day after pigging?

Pigs need more than 30 kinds of nutrients in the process of growth and development, such as water, energy feed, protein, vitamins, minerals, sugar, crude fiber and so on. The more nutritious the feed, the faster the pigs will grow. The nutrients given should not only meet the needs of pigs to maintain their mission, but also meet the needs of pigs to grow. A pig with a gross weight of about 80 kilograms needs 2900 calories a day to maintain life. Each kilogram of rice has only 1330 calories, and it takes 2.3 kilograms of rice every day to maintain the life of a pig. Only by increasing feeding on this basis can pigs grow. Feeding pigs with compound feed can shorten the feeding time. There are many kinds of feed in rural areas, which can be made into compound feed to meet the needs of pigs for nutrients. Middle-aged pigs with gross weight 100kg should be fed a mixed feed of 8000- 10000 calories per day, based on the daily gain of 2 kg (including the need to maintain life and growth). Such as corn 1 kg, rice 0.5 kg, peanut bran 0.5 kg, cassava/kloc-0.5 kg, bran/kloc-0.5 kg, chicken manure 1 kg and fish meal 0.2 kg. Green feed is about 8 kg. The daily cost of this compound feed is about 1 yuan. If the feed is single, protein and calories can't meet the nutritional needs of pigs, which wastes feed, manpower and income. ?

Second, how to feed pigs?

1, quantitative at regular intervals. The time and amount of feeding pigs every day are fixed, so that pigs can develop the habit of eating and urinating regularly and form conditioned reflex; In this way, about half an hour before feeding, pigs will secrete a lot of digestive juice, improve the digestive ability of the stomach and make full use of the nutrients in the feed. If you eat early and eat late, it will disturb the secretion function of digestive gland and even cause diseases of digestive system. So, how many meals a day is appropriate? According to my experiment and others' experiments, piglets are fed regularly for 6 times and fattening pigs are fed regularly for 4 times, and the feeding amount of each meal is basically balanced. This is good for pigs to gain weight. If there is not enough feeding time for each meal, pigs will be upset when they are hungry, and they will definitely not grow well. But feeding too much will affect the appetite of the next meal, and generally you can feed it to 90% full. If the feed needs to increase or decrease or change varieties, it should be done step by step, so that pigs have an adaptation process. ?

2, first thick and then fine, and then feed Qingke. According to the growth requirements of pigs, coarse feed is fed first, and then fine feed is fed to Qingjia; Feed less and add more. Generally, a meal should be fed three times, so that pigs can finish it in half an hour, and there is no leftover material in the trough. When pigs don't want to eat, each pig should be fed 1-2 Jin of fabric: don't chop up the green material, let the pigs chew and bring saliva (saliva) into their stomachs; Because saliva contains amylase, it can turn starch in food into maltose, which is beneficial to absorption. In this way, pigs can increase their appetite, eat well, sleep well and grow fast. ?

3. Raw feeding is better than specific heat feeding. When the feed is cooked and fed, many nutrients in the feed will be destroyed by high temperature, wasting labor and fuel. Using raw feeding method can not only ensure that nutrients are not lost, but also save artificial fuel. Except for potato, taro, pumpkin, cassava, bean dregs and other feeds with high starch content, all other feeds can be eaten raw. There are two kinds of raw material feeding: soaking and fermentation. ?

Soaking method: all kinds of feed are crushed and mixed evenly, and soaked in barrels (or tanks and ponds) according to the needs of pigs every day. According to the weight of 1: 1, put clean water first and then feed. Don't stir, let it soak naturally. Soak for 3 hours in summer and autumn, and soak for 4-5 hours in winter and spring to feed pigs. ?

Fermentation method: mainly fermented with coarse feed, such as pod, peanut vine, dried sweet potato, rice straw, chaff, sesame stalk, hay, bran, etc. Firstly, these coarse materials are fully crushed, and then koji seeds are added for fermentation. The first fermentation should use good koji seeds, and the second fermentation should be mixed with 3-5% of the first fermentation materials, so that it can be passed down from generation to generation. When mixing materials, 1 100 kg of water should be added to 165438 and adjusted according to different seasons. Generally, it is advisable to hold your fingers tightly so that water drops do not drip; Warm water is used in cold weather and long running water is used in hot weather. Fermentation time: 2-3 days in winter and spring, about 1 day in summer and autumn. Don't ferment too much at a time to prevent fermentation from deteriorating. Pigs don't like it. ?

4, timely supply of water and greening materials. Water accounts for a large proportion of pigs, with medium and small pigs accounting for 60-70% and large pigs accounting for 40-50%. Water plays an important role in nutrition transportation, body fluid secretion, waste removal and body temperature regulation of pigs. If you don't drink water for three days, you will be in danger. Because after guiding pigs to eat concentrate, they should be given thirsty water to drink. Put clear water between meals (another sink is set to hold water), so that pigs can form conditioned reflex to drink water and drink water regularly. ?

Green feed not only contains enough water, but also contains many vitamins. If there is no green feed, the growth of pigs will be hindered. Jiang did an experiment in Dangyang County, Hubei Province. The average daily weight gain of pigs fed with green feed was 2 Liang compared with that of pigs fed without green feed. It can be seen that green feed plays an important role in the growth of pigs. Each pig should be fed1-2kg green feed after each meal. ?

Third, timely supplement nutrition for newborn piglets?

Newborn piglets develop rapidly and need all kinds of nutrition to grow healthily and have a high survival rate. Therefore, it is necessary to strengthen management and replenish materials in time. ?

After the pig is born, it needs about 7 mg of iron every day during its growth. The amount of iron brought by newborn pigs from the mother can only last for 4-5 days, while the iron content in pig milk is extremely low. If iron is not supplemented, anemia, pale body color, loss of appetite and diarrhea will occur. From June, 65438 to June, 0982, we conducted an iron supplement experiment for piglets in Zhangdaozhu's home, Zhaoyang Village, Huaci Township, dangyang city City, Hubei Province. His 1 1 piglet is white and lifeless five days after birth. We use 2.5g of ferrous sulfate, 1 g of copper sulfate and 2.2g of cobalt chloride, which are dissolved in1000g of warm water and filtered into bottles with cotton. When piglets are nursing, dip this potion in clean cotton and apply it on the nipples of sows, so that piglets can absorb iron when they are nursing, and the body color of piglets will gradually turn from white to red the next day. After two days of stopping soaking, You Zhu turned white. In the future, the sow's nipples will be coated with liquid medicine every day, and the piglets will remain rosy and grow rapidly. You can also inject 150-200mg iron when piglets are 2-3 days old. One injection can meet the needs of piglets for about 20 days. Piglets can get iron from feed in the future, so there is no need to supplement it. ?

Piglets begin to teether on the eighth day after birth. When teething, the gums itch. If not supplemented in time, piglets will find feces and sundries to eat, leading to dysentery and enteritis. The feeding method can be to fry barley, soybeans or rice, grind them into sesame-sized particles, and put a little in a shallow basin where young pigs often move to lure and train young pigs to eat. The fried food smells good, and pigs like it very much. At the same time, you can cook some porridge and sprinkle the fried powder on the porridge, so that the pigs can learn to eat feed early. At this time, mineral additives can be added to the feed to supplement the nutrition of piglets in time to avoid getting sick. ?

Fourth, the methods and steps of fattening?

If you want pigs to grow fast, you must pay attention to the feeding methods. The bought (or autotrophic) piglets were raised and observed for 3-5 days. If no disease is found, it can be treated with deworming, gastric lavage, stomach strengthening and nutrition strengthening to make it grow rapidly. The practice is:?

The first day, deworming. Use trichlorfon (available in local pharmacies) and feed it to 10/piece per 1 kg of pig hair. Before deworming, let the pigs starve. At 7-8 pm, mix the ground trichlorfon slices into a small amount of feed, so that the pigs can eat it all at once, so that every pig can eat it. Experiments show that the effect of insect repellent at night is better than that during the day. ?

On the third day, gastric lavage. Use 3 yuan baking soda (flour alkaline powder) to mix in the feed in the morning and feed it to the piglets to wash the dirt on the gastrointestinal mucosa. ?

On the fifth day, strengthen the stomach. Feed rhubarb soda tablets 10 kg gross weight to 1 tablet, and mix with the feed for three meals to enhance intestinal peristalsis. ?

After deworming, gastric lavage and appetite enhancement, the harmful substances in the intestines and stomach of pigs have been removed, and the intestinal wall has become thinner, which is convenient for absorbing nutrients. At this time, feed additives are added to the adjusted feed. Pigs have a strong appetite, rosy fur, like to sleep and gain weight quickly. More than 2,000 pigs in our experiment, each pig that started fattening above 80 kg gained more than 2 kg per day on average, and each pig that was 30-80 kg gained more than 1 kg on average. The additive used is produced by Guangzhou Military Region Corps of Engineers Farm (Guangzhou Bamboo Material). During the fattening period, the daily dosage is only 2 cents. This unit can handle mail orders. ?

Two months after the first deworming and fattening, deworming, stomach listening, stomach strengthening and fattening were carried out again according to the above methods. After the second fattening, weaned piglets weighing 30 kg can generally reach 180-200 kg after 4 months. ?

5. How to fatten pigs with green feed and roughage?

Green feed and roughage are rich in sources. Feeding pigs with roughage instead of roughage can reduce the cost of raising pigs. Experiments show that feeding pigs green feed and coarse feed in multiple meals will also increase the daily gain of pigs. ?

We used raw feeding experiment to mix fermented coarse feed and a small amount of concentrate with chopped green feed and a small amount of water, and fed it regularly for 6 meals every day. After eating the mixture, the pigs put in some green feed that has not been chopped, and let the pigs eat freely. Pigs sleep when they are full and eat when they wake up. In this way, the gastrointestinal tract of pigs is always full of food, so it is not called hurdle. 100 kg pigs can gain 1.5-2 kg daily. ?

Why do pigs gain more weight every day when eating green roughage? According to the physiological analysis of pigs, the main reasons are:

1, the purpose of regular multi-meal feeding is to make pigs eat more, ensure nutrition and create a rich material foundation for the rapid growth of pigs. Roughage has high nutritional value and long residence time in gastrointestinal tract, while green roughage has low nutritional value and short residence time in gastrointestinal tract. According to the digestive function of pigs, concentrate feed should be used for four meals and green coarse feed should be used for six meals. With the multi-meal system, pigs can eat well, digest normally, grow healthy and howl uneasily. ?

2, multi-meal feeding is conducive to maintaining gastrointestinal function and absorbing nutrition. In the traditional feeding method, pigs have a lot of water. In order to fill their stomachs, pigs eat food without care. As a result, their stomachs are full, but there is little dry matter. The interval between meals is long and irregular, which causes the gastrointestinal tract to expand when there is food and contract when there is no food, which damages the function of the gastrointestinal tract, causes the intestinal wall to be enlarged and the nutrition is poorly absorbed, thus the growth is slow. Regular multi-meal feeding is adopted, and the intestines and stomach are often filled with food, which ensures the open state and can better absorb nutrition. ?

3. By feeding with multiple meals, the sleep time of pigs is increased. When the number of times pigs eat increases, the workload of their intestines and stomach increases correspondingly, and a large amount of blood flows to the intestines and stomach, leading to cerebral ischemia, functional decline, coma and sleep. In this way, pigs will eat more, sleep more and exercise less, and their energy consumption will be reduced, so that the nutrients they eat can be fully supplied for fattening. Therefore, feeding green and coarse grains in multiple meals can also achieve the goal of accelerating fattening. ?

Is chicken manure a good feed for raising pigs?

Chicken manure is a good feed for protein. Feeding pigs with chicken manure not only has high nutritional value, but also can save concentrate. According to the laboratory analysis, the lysine content of chicken manure is 65438 0.5 times higher than that of grain feed, including crude protein 28-33%, crude fiber 65438 0.3%, calcium 7.8% and phosphorus 2.65438 0%. Fat is high in heat energy and rich in vitamin B, and the chicken manure of every 10 chicken can be collected to solve the protein feed of a pig. According to the experiment, it is very effective to feed 100 kg of treated chicken manure to pigs every day. ?

Collection method of chicken manure: firstly, clean the chicken coop (cage), add lime for disinfection, and then leave the chaff in the chicken coop or on the manure board under the cage. It is collected every 3-5 days in winter and spring, and every 1-2 days in summer and autumn. The collected chicken manure is fully crushed. The chaff scattered in the pen should not exceed 50% of chicken manure, and the chaff should be fully mixed with chicken manure. Adjust it with warm water in winter to the extent that it can be dispersed by hand. Finally, put it into a jar, pot or reed for fermentation. Don't press it too tightly to facilitate ventilation. When the temperature is low, cover and keep warm. 1-2 days later, when you smell the wine, you can feed the pigs. When feeding, in addition to mixing concentrate, you can also feed concentrate first and then chicken manure. If the amount of chicken manure is too much, fresh chicken manure can be dried or dried, crushed and put into plastic bags for later use. Ferment or steam fry before use to prevent coccidia in feces from being transmitted to pigs. ?

7. Preparation and function of calcium carbonate and sulfide stone?

Calcium carbonate: Calcium is an essential nutrient for the growth and development of livestock and poultry. If livestock and poultry lack calcium for a long time, breeding animals will suffer from rickets and sexual desire will decrease; Young animals suffer from rickets; Young animals have diarrhea, loss of appetite, slow growth and even weight loss; The number of eggs decreased, and symptoms such as soft feet and raw soft eggs appeared. Therefore, calcium must be added to the feed, and limestone is rich in resources. If calcium carbonate is processed by ourselves and used to feed livestock and poultry, the cost is low and the effect is good. The method is:

According to the required quantity, prepare a tank, basin or dig a large pool for 1-2 years, put the burnt quicklime into the tank, basin or pool, add water and stir it, let it soak for about a week, remove the clear water and the lower gravel, pick it up and dry it, and store it in small pieces. Turn it every few days during storage, so that it can fully contact the air and inhale carbon dioxide. The longer the storage time, the higher the calcium content. When it is used, it is ground into fine powder (if it is fed to laying hens, the remaining lime slag powder can be used to build houses, because chickens need sand). This lime powder contains more than 70% calcium carbonate and a small amount of magnesium oxide, iron oxide and potassium oxide. ?

The dosage of this calcium carbonate is: calculated by dry matter feed, 65,438+0.5-2% for pig feed and 2-2.5% for poultry feed, which can be increased to 2-3% at the peak of egg laying. If it is excessive, phosphorus must be added, and the ratio of calcium to phosphorus is 2: 65,438+0 or 65,438+0.5:. ?

Sulfite: Sulfite is a kind of pig feed additive, which can not only promote the growth of pigs, but also resist bacteria and repel insects. It also contains sulfur, calcium, chlorine, sodium and other elements, which can meet the needs of pig growth for these minerals. Simple manufacture, self-made and low cost. ?

When raising pigs, the sulfate of pigs is mixed together according to the ratio of lime 1 kg (preferably old lime), salt 1 kg and sulfur 2-3, and then fried and ground. Feed 10- 15g per head every day. When pigs grow to about 100 kg, they are fed a mixture of 2 kg lime, 0/kg salt and 4-6 sulfur, and each pig is fed 15-20g every day. Reduce the burden? If it is troublesome to put it in the sky, it can be prepared according to the ratio of 100 kg feed to 0.8- 1 kg stone sulfur salt, but it must be fully mixed. ?

8. Production and use of several auxiliary nutrients?

Pig hair, chicken feathers, duck hair, other feathers, eggshells, etc. all contain a variety of essential amino acids, tryptophan, methionine, cystine and other nutrients. Hair residue can be treated in a simple way and used as feed additive instead of fish meal. ?

Processing and utilization of coarse slag: firstly, put all kinds of coarse slag into a container (aluminum containers are not allowed), add 7 kg of water to the coarse slag according to the ratio of 1 kg and boil it in the container, then add 45 g of calcium hydroxide, and cook it with strong fire for 10- 15 minutes, and the coarse slag will dissolve into liquid. If pigs are fed with hair residue solution, each pig takes a spoonful of each meal and mixes it into the feed; If it is too much to preserve, it can be mixed with bran to dry and preserve. When adding, it should be added quantitatively according to the amount of bran. ?

Processing and utilization of shells, eggshells, bones and limestone: firstly, these raw materials are baked on charcoal fire, and then collected and ground for use. The big pig is fed 10- 14g every day. If limestone powder is added, add 6-7 ounces to 100 kg dry material. At the same time, a small amount of phosphorus and zinc are supplemented. ?

9. What's the effect of salt on pigs?

Salt can stimulate animals to secrete saliva, and enzymes in saliva can promote food digestion. Regular salt supplementation can improve feed utilization rate and gain weight. Feeding salt regularly can make pigs grow faster and save feed. According to the experiment, the daily feed intake of 8 kg piglets without salt is 0.42 kg, and the daily gain is 0.14 kg; Adding 0.5% salt to the diet, the daily intake is 0. 18 kg, and the daily gain is 0.62kg.. Practice has proved that adding salt to pig food is extremely beneficial. ?

The salt requirement of pigs generally accounts for 0.5- 1% of the diet weight, so it is necessary to supply enough drinking water when adding salt. If the salt content exceeds 4-8%, pigs will be poisoned and die. ?

Ten questions about raising pigs?

1. How many pigs should be raised in each pen? ?

Generally, each pig covers an area of about 1.5 square meters. For example, a 15 square meter pigsty should have 8- 10 pigs. In this way, it is good for pigs to eat, sleep and move. Raising too many pigs, strong pigs grab food quickly, and weak pigs don't have enough to eat and sleep well, which affects their growth. ?

Second, why do pigs stir? ?

The causes of pig commotion, such as jumping over fences, arching the ground, gnawing at the wall soil, gnawing at the trough and not sleeping, are not only worms in the stomach, but also malnutrition. Pigs need more than 30 kinds of nutrients, such as heat, protein, amino acids, minerals and vitamins. In rural areas, pigs are fed with a single feed, which is mainly diluted by cooking, so that limited nutrients (such as vitamins in green feed) are lost during cooking. Pigs can't get all the nutrients they need, so they try their best to find food. We once did an experiment and bought four lean pigs from a farmer's house to raise. These pigs have been raised for seven and a half months, and each pig weighs only 35 kilograms on average. After feeding for two months, the average weight of each pig reached 1 1 1.25 kg, and each pig gained 35 kg per month. The main method is to feed well (nutritious feed). It can be seen that as long as pigs are supplemented with various mineral elements and fed on time, there will be jumping hurdles, arching and gnawing at the wall soil. ?

Third, why should pigs supplement "additives"?

Most farmers use plant feed to raise pigs, which has few species and malnutrition. "Additive" is the part that is insufficient to add nutrients to general feed. At present, the additives produced by the Bamboo Farm of Guangzhou Military Region Corps of Engineers are comprehensive in nutrition, consisting of more than 30 kinds of nutrients such as antibiotics, amino acids, various minerals, vitamins and trace elements. Supplementing it into malnourished feed has high utilization rate, which not only saves the time and labor of finding feed, but also makes pigs grow fast and gain a lot. For example, Xu of Shi Cun, Maolin Township, Yulin City, fed four middle-aged pigs with "additives" produced by engineers of Guangzhou Military Region the year before last, with an average daily gain of 1.05 kg. ?

Fourth, how to use and mix pig feed?

There are a wide range of feed sources in rural areas, which can be reasonably matched with agricultural and sideline products such as green feed and grain to feed pigs. Rice, corn, peanuts, beans, sorghum, sweet potatoes, cassava, etc. , not only contains starch and crude fiber, but also can be mixed into pig feed by farmers themselves. The vines, stems and pods of agricultural and sideline products can be used as crude fiber feed, such as 0.3 kg of dried flowers and raw vines, which is equivalent to 0.5 kg of wheat. Crushed pods and bean stems and leaves are better thermal energy feed for pigs. Jade core contains sugar and can also be used as coarse grains. If you want to raise pigs well, you need a variety of crops, which have both heat energy and protein. The heat energy of corn and peanut vine is higher, and the protein content of beans and peanut cakes is higher. Fish meal mainly provides protein and vitamin B 12. If you can't buy fish meal, you can use fried bean powder instead, or you can increase the number of flower cakes. In places where rape is planted, rapeseed cake can be used to improve the protein level in feed. Where there is no vegetable cake, you can use bean cake. If you can't buy bean cakes, crush them with beans, cook them or fry them, and add them to the feed in proportion. ?

In addition, salt can account for 0.5- 1% of the feed, and "additive" accounts for 0.2%. When these mineral elements and "additives" are added, other feeds in the formula are reduced, so that the sum of each feed reaches 100%. Taro, beans, potatoes and melons with high starch content are best cooked before feeding, so as to facilitate absorption by pigs. Green feed mainly provides vitamins and should be fed every day. In the preparation of feed, we should try to be as diverse as possible to ensure comprehensive nutrition. ?

5. Why should the feed be used both wet and dry and cannot be diluted? ?

There are dry feeding, dilute feeding and dry and wet feeding in the process of raising pigs, and the dry and wet feeding method is better. Because when pigs start to eat feed, they should soak the feed with a lot of gastric juice, and pure dry feeding is harmful to the stomach. Dilute feeding, it seems that pigs eat a lot, but in fact, pigs eat mostly water, and their bellies are greatly elongated. However, too much water is not good for the physiological function of pigs. ① The feed eaten in the stomach can't be rubbed against each other, which affects digestion and absorption; ② Feed stays in gastrointestinal tract for a short time, excretes quickly and excretes a large amount; ③ Thickening of gastrointestinal mucosa and poor nutrient absorption; ④ The growth of pigs mainly depends on heat energy. Too much water, too much excretion, too much heat energy consumption, which hinders growth; ⑤ Diluted saliva in gastric juice can not give full play to the role of enzyme preparation, which is not conducive to digestion and reduces feed utilization. ?

Pigs eat more dry matter by dry and wet feeding. Gastric juice and saliva can play a good role in fermenting enzymes and fully decompose and absorb feed. Because of the high utilization rate of feed eaten by pigs, small gastrointestinal contractility, less excretion and low calorie consumption, pigs grow fast and gain more. In this feeding method, except for beans, potatoes, pumpkins and other feeds with high starch content, which need to be boiled with a small amount of water, other mixed feeds can be soaked or fermented and eaten raw. Immersion feeding: after the crushed feed (compound feed) is mixed in proportion, it is put into a bucket (cylinder) for soaking according to the daily needs of pigs. Effluent first, then effluent, and the weight ratio of material to water is 1: 1. Do not stir after feeding, soak for 3 hours in summer and 4-5 hours in winter and spring to feed pigs. Fermentation feeding: it is mainly to ferment with coarse feed (such as crop straw powder) and distiller's yeast such as wine cake, and it is appropriate to release water until the fingers hold it tightly and see water droplets without dripping. You can feed the pigs when you smell the wine. ?

6. What koji is used for beverage fermentation? What if there is no song? ?

Distiller's yeast seeds are also called enzymes. Fermented feed in rural areas generally uses distiller's yeast (that is, wine cakes for brewing). 5 kg of feed (3.5 kg of rice bran, whole bran 1.5 kg) and 3-5 pieces of distiller's yeast (about 0. 1 kg), pressed into powder, and evenly mixed with feed. For the second fermentation, you can add 5% of the feed of the first fermentation according to the total feed, without adding koji, and so can the third fermentation. This will continue to ferment from generation to generation ?

If you can't find koji, you can mix 50% bran and 50% chicken manure, mix well, add water to make powder that can be sprinkled by hand, pile it up and seal it with sacks or plastic sheets. Generally, it takes 1-2 days, and the temperature can be raised from normal temperature to above 60℃, and pigs can be fed when they smell the bouquet. ?

After chicken manure is fermented, it has no smell of wine, but it stinks. The reasons are as follows: ① chicken manure is stored for too long (chicken manure should be used within the same day or two days). (2) The chicken manure is not evenly mixed, and the wet and dry conditions are inconsistent. ③ The fermentation time is too long or too short (generally 2 days in summer and 3-5 days in winter). (4) Chicken manure contains a lot of residual disinfectants (such as formalin, Lysol and plant ash). ), destroying the nutrients in chicken manure and producing bad smell. Therefore, in order to make chicken manure fermentation successful, it is necessary to eliminate the factors that hinder fermentation. ?

Seven, pigs have a bad appetite and eat very little. How to make pigs eat hard? ?

Pigs have a bad appetite: there are many reasons. Such as: ① there are parasites in the body; ② Gastrointestinal diseases; 3 uneven feeding, when you are full and hungry, it disturbs the function of the intestine and lacks salt. Measures should be taken according to the etiology: ① expelling worms and strengthening the stomach; ② Radical treatment of gastrointestinal diseases; ③ Timely and appropriate feeding, adding salt to restore gastrointestinal function; However, it should be noted that salt should not be added in excess, otherwise it will cause poisoning. ?

Eight, how to feed the green feed with good effect? ?

Green feed had better not be fermented, cut or boiled. Keep the concentrate every day and then feed 1-2 kg of green feed for pigs to bite. Saliva (saliva) is very beneficial to feed digestion. If there is a lot of green feed, it can be stored on the surface or dried and crushed. This is easy to store and can be used to feed pigs when there is no green feed to supplement vitamins. ?

Is raw food better or cooked food better? Is it better to feed thinly or wet? ?

Feed the raw and wet, and feed the raw and cooked. Because raw dry feeding is nutritious; Because of the high water content, dilute feeding excretes a lot of body heat, while cooked feeding loses a lot of nutrients at high temperature. ?

10. Is it necessary to give stomach medicine every month? ?

Stomach-invigorating drugs may not be given every month, but if you can boil some water with the "Divine Comedy" or feed a few rhubarb soda tablets every month, it will be good for the gastrointestinal digestion of pigs. ?

The breeding method of Xiang pig can be referenced!

Xiang pig is small in size, delicious in meat, thin in skin and bone, and high in lean meat rate. Xiang pig has strong adaptability, high reproduction rate and high feeding value. The pigsty should be built in a sunny, dry, ventilated and hidden place.

The pigsty is plastered with cement or paved with floor tiles. The effective enclosure area of each breeding pig is 4 square meters.

The breeder's fragrant pigs are mainly fed with green feed to ensure the pure flavor of pork. Commonly used feeds include corn, millet, rice, wheat bran, rice bran, bean cake, peanut cake and so on. The protein content of Xiang pigs is different at different stages, and it is 14%- 15% for piglets aged 2-3 months. 4-6 months old pigs and lactating sows12%-14%; Empty sows 8%-10%; Breeding pig 13%- 15%. The dosage of concentrated feed is 1.5-2 kg per day for big pigs and 1- 1.5 kg per day for piglets. Powdered feed is stirred with clear water until it is dry and wet, and then fed. Feed pellet feed directly to ensure sufficient drinking water. Wash the green feed, chop it and mix it with concentrated feed, or feed it with concentrated feed without chopping it. The big pig is fed three times a day, and the little pig is fed four times a day. Sows are in estrus at the age of 4 months, and mating at the age of 8 months is the best, and mating can only be carried out at the earliest age of 6 months. Sows prepare advance feed for pigs to nest before giving birth. Stem pigs have good motherhood and strong protection for their young. Young literate pigs are not used to frequent approach, so the venue should be quiet and the light in the fence should not be too strong. After the newborn piglets dry their hair, they can move around the fence and suck their breast milk. Piglets are fed after 30 days of age, weaned at 50 days of age and raised separately from sows. Piglets that are not ready for breeding should be castrated during lactation, otherwise their growth and suckling pig quality will be affected. In the country of origin where the environment is pollution-free, Xiang pig has shown the advantages of tolerance to extensive management and strong disease resistance. However, when aquaculture is introduced in places with serious industrial pollution, special attention should be paid to environmental sanitation, regular cleaning of pens, replacement of utensils, disinfection and frequent replacement of bedding. It is forbidden to give pigs sewage, or to clean green feed and utensils with sewage. Feces and wastes are piled up for centralized treatment. At the same time, according to the local epidemic situation, all pigs were vaccinated according to the procedure. Newborn piglets should also pay attention to prevent red dysentery and white dysentery.
