杀灭动物饲料中的沙门氏菌。沙门氏菌被动物摄入体内后会保留在动物组织中，人吃了感染这种细菌的动物会得沙门氏菌的肠胃病。采用蒸汽高温调质再制粒的方法能杀灭存在动物饲料中的沙门氏菌。

Avoid animals being picky eaters.There are many kinds of ingredients in the feed formula with comprehensive nutrition, which can prevent animals from choosing their favorite food from the flour ａnd refusing to take in other ingredients.The feed loss can be reduced by 8%~10% due to the uniformity of granular feed in the process of storage, transportation ａnd feeding.

2

High returns on feed.In the process of granulation, due to the comprehensive effect of water, temperature ａnd pressure, some physicochemical reactions took place in the feed, which enhanced the starch gelatinization ａnd enzyme activity, ａnd could enable the fed animals to digest the feed more effectively ａnd turn it into weight gain.Feeding poultry ａnd pigs with granular feed can increase the feed conversion rate (i.e., the rate of return) by 10-12% compared with the flour.Feeding fat pigs with granular feed increased the average daily weight by 4% ａnd reduced the ratio of feed to meat by 6%.Feed broiler, raw meat ratio can be reduced by 3%-10%.

3

Storage ａnd transportation are more economical.After granulation, the bulk density of feed can be increased by 40-100%, which can reduce storage capacity ａnd save transportation cost.

4

Good liquidity ａnd easy management.Many powders, especially those with a small proportion of fluffy feed, are often adhered to the feedstock with molasses or high fat ａnd urea.Because granular feed is highly mobile ａnd rarely sticks, it is the most popular for large-scale farms that use automatic feeders to raise cows or poultry.

5

Avoid automatic grading of feed ingredients ａnd reduce environmental pollution.In the course of powder storage ａnd transportation, because the volume ａnd quality of various powder materials are different, it is easy to produce classification.After the granule is made, there is no grading of feed ingredients, ａnd the granule material is not easy to dust. In the process of feeding, the granule material pollutes the air ａnd water much less than the powder.

The END

Matters needing attention

Kill salmonella in animal feed.Salmonella is retained in animal tissues when ingested by animals, ａnd people who eat animals infected with the bacteria can develop salmonella enteritis.The salmonella bacteria in animal feed can be killed by the method of high temperature steam tempering ａnd regranulation.
