After drying, the digestibility of dry matter increased by 13. 17%, the metabolic energy increased by 16%, the digestible protein increased by 29.59%, and the crude fiber decreased by about 30%. It is also a carrier of probiotics, containing a large number of beneficial microorganisms, acidulants such as lactic acid, and vitamins, especially B vitamins, increase several times.

And:

① Improve the palatability of feed, reduce crude fiber by more than one third, make animals love food more, promote appetite and increase the secretion of digestive juice.

② Anti-nutritional factors were greatly degraded, and the disease resistance was improved. After fermentation, the digestibility and degradation of anti-nutritional factors were significantly increased, and a large number of beneficial factors were contained to improve the disease resistance.

(3) the feed cost is saved, the economic benefit is improved, a large part of feed can be replaced after fermentation, the feed cost is saved, and pigs are less sick, and the slaughter is advanced, in short, the economic benefit is improved.

When feeding fermented feed, we should adopt the principle of small amount first and gradually increasing it. At the beginning of feeding, we can adopt 10% first and gradually increase it to 30% and 50%. Piglets are added according to 20%-30% of the feed. Big pigs, chickens and ducks are added according to 30-50% of the feed (calculated by dry matter). The feed formula for fattening pigs is mainly bean dregs with high content of protein, and the amount of feed corn with high calorie such as corn should be increased to 30% ~ 40%. In addition, proper amount of vitamins, bone meal, salt and green feed should be matched in each period.
