In recent years, with the rapid increase in the number of chickens, chicken manure is a large amount of valuable feed resources. It has been proved by practice that chicken manure contains 13-30% crude protein and 2-4% crude fat. The crude fiber is 10-14%. Therefore, chicken manure is a good feed for feeding pigs. However, due to the fact that there are many microorganisms in the fresh chicken manure, some organic matter can not be directly used. In addition, the chicken manure has poor palatability and the pigs do not like to eat. Therefore, farmers should do a good job in the development of this feed. To use, it is necessary to solve the following problems when feeding pigs with chicken manure.
1. The necessary processing must be carried out. Chicken manure used as pig feed must be processed before being fed before feeding. The commonly used methods of processing are as follows:
(1) Natural drying: Spread the chicken manure on clean cement floor or plastic cloth, dry it naturally or dry it, dry it and then smash it for use.
(2) Mechanical drying: It is the chicken manure drying with a dryer, when the water content drops to 13%.
(3) Fermentation treatment: Mix the chicken manure with bran, rice bran, compound feed, straw powder, etc., then add water to the large tank or cement tank according to 1:1, and then seal the mouth with plastic film. After 4-5 days of fermentation, the feed turns yellow-green and gives off the aroma of the wine.
(4) Silage treatment: use chicken manure 60%, short straw 30%, bran 10%, mix it, the humidity can be controlled at 60-70%, the tamping is sealed, and the silage can be 30-50 days.
2, chicken manure must be fresh. The chicken manure collected by the pigs must be fresh, especially in the summer. Due to the high temperature, the chicken manure is prone to deterioration, so the chicken manure that has been more than 24 hours has become corrupt and can not be used.
3, we must do a good job of feed transition. When farmers use chicken manure to feed pigs, they must adopt a small increase and gradually increase the pigs to have an adaptation period.
4. It is forbidden to feed alone. Due to the low energy value of chicken manure, it must be used in conjunction with high-energy feed when used to feed pigs. At the same time, in order to improve and enhance the palatability of chicken manure feed, it is best to add sugar confections, and conditionally can also be processed into pellet feed, and the effect is good. Chicken manure feeding pigs generally accounts for 10-30% of the diet.
5. It is forbidden to feed pigs with chicken manure in infected areas and sick chickens. Because some chickens and pigs have infectious diseases in chicken feces in infected areas or sick chickens, in order to ensure the safety of pigs, it is strictly forbidden to feed pigs with chicken manure from sick chickens.
6. It is forbidden to feed pigs with chicken manure with high copper content. In particular, the feces of chickens and chickens contain a large amount of copper. In order to prevent post-prandial poisoning caused by excessive copper, do not use chicken feces with high copper content to feed pigs.
