How to remove ammonia from piggery without cleaning feces in winter?

Piggery that does not need to clean feces is generally recommended as an elevated bed for raising pigs. Generally, pigs are raised above, and feces are piled up at a height of one meter below. The height of the first floor is changed from the original height of 1m to 2.5m In order to prevent the excrement from flowing out and polluting the environment, a certain degree of tightness should be maintained between the two floors, and generally the whole building should be sealed. At the same time, automatic exhaust fans should be installed in the pigsty, so that the feces can be cleaned once every four months, and it is best to lay a layer of cement floor with appropriate gaps.

First, the pigsty is designed without cleaning feces.

1. Pighouses that don't need to clean feces generally recommend raising pigs on elevated beds. Pigs are usually raised on it, and feces are piled up at a height of one meter below. Keep a certain degree of tightness between the two floors, and clean up the feces every four months, which is much more labor-saving than other pig houses.

2. Usually, the height of the first floor is changed from the original 1m to the height of 2.5m, so that pig manure can basically accumulate and ferment here for four months from entering the circle to leaving the circle, and there is plenty of room for loading manure. In order to prevent feces from flowing out and polluting the environment, the whole building can also be closed, because the polluted air will have a great impact on pigs after the space is closed, so it is necessary to install automatic exhaust fans in the pigsty.

3. Generally, the cracks on the cement floor are easy to leak feces, but the pig's feet are also easy to be caught. If cracks are reduced, pigs will not pinch their feet, but the effect of leaking feces is not very good. If the gap size is appropriate, it is recommended to use reinforced materials. It is necessary to design drinking water tanks in the walls of pigsty. Every time a pig drinks water, he can only stick his head into a hole in the wall. When playing, the water flowing out will be collected through the pipeline and recycled, which will not affect the fermentation of feces on the first floor.

4. It was found that there was a strain with strong performance and stable passage in pig large intestine. After the developed protobacteria strains are expanded, they are added to feed by feed processing plants and then processed into fermented feed. After being eaten by pigs, this strain has a high survival rate in gastric juice.

5. Generally, the whole pigsty and manure pile can be sprayed with cultured probiotics every 3-5 days. Before the feces decompose, a small amount of fly maggots will grow. At this time, you can put some chickens in the pigsty, usually a dozen chickens in a pigsty. With the continuous fermentation and maturity of pig manure, chickens will grow up slowly, which can not only effectively ensure the healthy growth and development of pigs, but also help farmers get more economic benefits.

Second, how to remove ammonia in winter piggery

1, strengthen ventilation

(1) The main reason for the high ammonia content in pigsty in winter is that it is too closed.

(2) It is the best choice to remove ammonia by strengthening ventilation and discharging ammonia in the house. There are many ways of ventilation. If there is a fan, you can turn it on, or you can turn on the vents, doors and windows for ventilation, so that the air in the pigsty can convection.

(3) Attention should be paid to ventilation in winter, and it should be carried out at noon when the temperature is high under the premise of ensuring the temperature of the pigsty, so as to avoid pigs being blown by the wind and causing colds.

2. Strengthen management

(1) To raise pigs in winter, it is necessary to strengthen the daily hygiene management of piggery, remove excrement such as feces and urine produced by pigs in time, and prevent drinking pig water sources from being polluted.

(2) Keep the pigsty environment dry and clean, pay attention to regularly check the feeding equipment, and carry out cleaning and disinfection, reduce the source of toxins, ensure that the water source is clean enough, and pay attention to the integrity of drinking water equipment to avoid dripping and leaking, and avoid the increase of pigsty humidity.

Step 3 control density

(1) Due to the low temperature in winter, many farmers will increase the breeding density appropriately to raise the temperature of pigs in order to keep them warm.

(2) Although this method is really beneficial to heat preservation, it should not be placed too close. If the feeding density is too high, the ammonia content may increase, which will affect the growth and development of pigs.

(3) Therefore, it is necessary to make a reasonable plan when regulating the pig breeding density in winter. If it is a fattening pig, the area is about 1.5 square meters, and if it is a fattening pig, it should be controlled at 0.5 square meters per head.
