Shi Zhuangzhuang Agricultural School Zhang Zhanfeng A: The ratio of the length of the chicken's digestive tract to the body's length is relatively small compared to other animals, especially mammals. This shows that chickens are relatively short animals in the digestive tract. Based on this, the residence time of the feed in the digestive tract is relatively short, usually 3 to 4 hours, so the emptying rate of the feed in the digestive tract is very fast. Therefore, the digestibility and absorption rate of feed for chickens are not too high for other animals. The study found that about 70% of the feed was not completely digested and absorbed by the chicken. Through feed analysis, crude chicken manure contained 22.5% crude protein, 2.3% crude fat, 22.9% nitrogen-free extract, 9.7% crude fiber, and 34.6% crude ash. It can be seen that the nutrients in the chicken manure are very abundant. Therefore, the chicken manure can be used as a pig feed completely.
When using, you must pay attention to the following issues:
1. It is forbidden to use fresh chicken manure as pig feed, because fresh chicken manure is extremely susceptible to a large number of pathogenic microorganisms. If fresh chicken manure is used as pig feed, it will undoubtedly increase the chance of pigs suffering from infectious diseases.
2. Fresh chicken manure must be scientifically processed before it can be used as pig feed.
3. When using, must according to the pig's different physiological stages, different uses, different ages to add the appropriate amount of processed, modulated chicken manure.
4. Chicken manure cannot be used alone as a pig feed and must be mixed with other feed ingredients in a certain proportion before use.
5. Finishing pigs for 15 days before slaughter are strictly prohibited from feeding chicken droppings to ensure the quality of pork.
6. Before using chicken manure as pig feed, it is best to identify chicken manure for pathogenic microorganisms.
