Pork chicken dietary fiber content should be moderate

Everyone knows that although the crude fiber in the feed is not easily digestible, it cannot be used without feed. One is that crude fiber can increase the volume of feed and play the role of filling volume in the digestive tract, which can make pigs, chickens, and other animals resistant to hunger. Some people have used the diets with different levels of crude fiber to feed chickens. It was found that when the crude fiber content is too low, the feathers of the chickens do not grow well and there is a phenomenon of feeding on feathers or licking. When the crude fiber content is appropriately increased, it can be prevented. Occurs. This is due to the fact that the chicken's pods often have a full sensation, hunger is caused by feeding and causes spasms; second, coarse fibers can stimulate gastrointestinal motility, facilitate the excretion of feces, thereby enhancing appetite and promoting the enhancement of metabolic function.

So, the more crude fiber in the feed, the better?

Nor is it that the excessive presence of crude fiber in the feed is detrimental to the growth and health of livestock such as pigs and chickens. Crude fiber-rich feeds are generally rough in texture and poor in palatability. Crude fiber is not only difficult to digest and decompose, but it also hinders the contact of other nutrients with various enzymes and reduces their digestion and utilization. If the crude fiber content in the feed is 10%-20%, the digestibility of the organic matter is 72%; when the crude fiber is increased to 40%-50%, the digestibility of the organic matter is reduced to 54%. Therefore, pigs and chickens have too much crude fiber in their diets, and the diet volume is enough, but other nutrients are reduced. As a result, the lack of nutrition due to digestion and utilization and insufficient energy results in poor growth and development of pigs and chickens, loss of weight, and reduced egg production rate.

In the feed, there is no crude fiber, nor too much. So, what is appropriate for containing crude fiber in pig and chicken diets? According to practice, the crude fiber content in the diet of chickens is not more than 5%. The general standard is 2.5%-3% for young chickens, and 3%-4.5% for young chickens, laying hens, and breeders. The crude fibre content of pig diets must not exceed 15%-18%.
