First, the role of brewers' grains 1. Supplement with real protein. Brewer's grain fermentation temperature at 40 °C, can break down fungal protein. Such as yeast, lactic acid bacteria, cocci, Bacillus subtilis, streptococcus faecalis and other chicken intestinal absorption of the true protein, is the source of the product needs. 2, add soluble vitamins. The bran in the brewer's grains can release vitamin B1, vitamin B2, and vitamin C during the fermentation process, which can not only regulate the balance of the intestinal environment and pH, but also improve disease resistance. Second, the use of methods 1, dry feed. In the spring and summer, the brewer's grains can be dried on the concrete floor and collected. In the winter season, the chicken is allowed to feed freely with a mix of 5% to 10%. 2, wet feed. It is to ferment fresh beer dregs on the cement floor for 12-24 h, so that the temperature can reach 70°C. Mix the mixture with 10%-20% of the mixture to allow chickens to feed freely, or regular ration. Each chicken feeds 20 ~ 30g, can increase the egg production rate by 15%, extending the number of months of egg production. Third, pay attention to matters 1, the winter to feed fresh beer worse to prevent freezing, to extend the fermentation time, so that yeast, lactic acid bacteria to fully reproduce. 2, summer feeding to prevent rancidity, anti-poisoning. To properly shorten the fermentation time, promptly remove heat.
