How many days is it appropriate for piglets to wean?

Pig farmers all know that piglets need to be weaned after surviving the lactation period with high mortality and morbidity, and go in to protect the pigsty. The big problem in this period is over-exploitation, whether it is feed or management. If you don't do it well, it's easy to get stressed. So, how many days can a newborn pig feed? How to match the feed for weaned piglets?

How many days can newborn piglets be fed?

It usually takes about 15 days.

How to match feed for weaned piglets.

1. Preparation of high-quality protein raw material: reed branch puffed soybean instead of soybean meal. The digestion effect of expanded soybean on piglets is better than soybean meal. It can improve the diarrhea rate of early weaned piglets, and the daily gain of early weaned piglets can be increased by 40%, and the daily gain per kilogram is 0. 12 kg.

2. Adding synthetic lysine: It can improve the balance of amino acids in feed and reduce the protein level of feed, thereby reducing the plant protein content, reducing the burden of digestive tract, and avoiding or reducing the production of a large number of toxic substances in the hindgut due to plant protein allergy and protein's indigestion.

3. Adding enzyme preparation: it can make up for the deficiency of low enzyme activity in digestive tract of early weaned piglets, improve the digestibility of indigestible polysaccharides in diet, reduce anti-nutritional factors and reduce intestinal viscosity, thus improving the nutritional value of feed, promoting the digestion and absorption of nutrients, eliminating indigestion and reducing the occurrence of diarrhea.

4. Luzhi acid preparation: insufficient gastric acid secretion within 4 weeks after birth can make up for insufficient gastric acid secretion and induce gastrointestinal secretion of hydrochloric acid and digestive enzymes in piglets.

5. Flavoring agent: Piglets have obvious preference for sweetness. Flavoring agents are helpful to the sale of feed. When selecting a new feed formula, making flavoring agents can help prevent the decrease of feed intake.

6. Prepare piglet feed according to the age of weeks, increase the growth rate and reduce the production cost according to the actual needs.

How to manage newly weaned piglets?

1, mixed group and column of piglets

Piglets are prone to fight in order to avoid position competition. In order to avoid weaning, we usually adopt different methods day and night, neither too big nor too small, and many of them keep male and female, weight, breed, gender and so on.

② Training and "three-point positioning" should be done well when merging columns. Provide the area of the fence according to 0.4m2/head.

2. Changes in feeding methods

Weaned piglets can not fully adapt to solid feed and have poor digestive function. If they eat too much, it is easy to cause digestive dysfunction and diarrhea. The stronger the pigs in production, the more likely they are to get sick at this stage.

Methods: A certain amount of antibiotics and antiallergic drugs were added to the feed at the early stage of weaning, and the feces were observed. If it is still normal after one week, you can take completely free feeding.

Attention: clear the trough in time to prevent feeding moldy and deteriorated feed; Pay attention to electrolyte supplementation and insect repellent (adding drugs or intramuscular injection of levamisole or killing pests) after three weeks.

3. The change of feed type

Weaned piglets can't change piglet feed immediately, so it takes several days to change from suckling pig feed to nursery. Generally, the method of changing feed gradually is adopted within one week.

Once any abnormality is found in the process of material transfer, stop the material transfer immediately and continue to refuel after the situation improves.

Pay attention to provide clean drinking water and electrolyte, and add drugs in the process of material transfer.

4. Environmental changes

① Just weaned, try the original bar feeding;

(2) Nursery room should have good environmental sanitation conditions, try to use high-bed leaky floor, and the temperature and humidity are easy to control; Sterilize and leave the column empty for one week before transfer.

③ Don't inject vaccine within 0/0 days after weaning to avoid stress;

④ Weaned piglets are afraid of cold, and the temperature should be adjusted well. Prevent the temperature difference between day and night from being too large, there can be no direct airflow, and the room should be dry and ventilated. Methods: The room temperature was required to be 27℃ (25℃ before weaning), and then decreased by 1-2℃ every week until 22℃.

5. Matters needing attention in management

① Regularly observe the feed intake, behavior dynamics, feces and sleep of piglets;

(2) Feed frequently and add less, forming a law;

(3) Avoid strangers coming in and out, and prevent the whole group of piglets from feeling and pressure;

④ Pay attention to ventilation and solve the contradiction between ventilation and thermal insulation; Keep the house dry, clean and hygienic;

⑤ Vaccination is not suitable at the initial stage of population transfer to avoid multiple stress.
