There are many benefits to feeding chicken with grain feed.

The cereal feed or granule batch is heated in a high temperature air of 160-187 ° C for 1-2 minutes to heat the moisture inside the grain to the evaporation point, so that the grain feed expands, and the volume is increased by 30%-40%. Then crush the chicken. It has been reported that feeding the chicks with puffed feed can improve feed utilization.

Soaking in the grain feed for one night, germination at a temperature of 20-27 ° C, where the light is dark, can cause mashing of the starch, increase the content of protein and soluble B vitamins, and improve palatability. It is said that feeding germinated barley in winter can increase the egg production rate of chickens by 10%-12%. It has been reported that ordinary sorghum lacking lysine germinated for 3-4 days at 30 °C, and lysine, methionine and tryptophan of sorghum were increased by 2.2, 1.8 and 5.7 times, respectively, before germination.

Beans, potatoes, cereals (for feeding ducks) and animal feeds (such as cockroaches, raw fish, etc.) can be cooked to increase palatability, ease of digestion, and kill harmful bacteria. However, the feed cooking time is too long, the protein coagulation is not easy to digest, and the vitamin is destroyed, but the nutritional value is lowered. Therefore, whether or not cooking depends on the specific situation.

The cottonseed cake can be placed in a pot with a closed lid, and cooked until the cottonseed cake turns brownish red, and the water is squeezed out to achieve the purpose of detoxification.

The rapeseed cake can be roasted and the scent is emitted to promote the appetite of the chicken, and the bacteria and mold hidden in the feed are killed. The roasted rapeseed cake, black mustard and white mustard are destroyed, thereby increasing the feeding value of the rapeseed cake.
