Feed yeast is a protein feed made by yeast fermentation using agricultural and sideline products waste or industrial waste. It has high protein content and easy absorption, and it is an ideal cheap protein feed. Chickens are very sensitive to feed yeast. Feeding with high-quality feed yeast has obvious effects, while feeding with fake and shoddy feed yeast has no effect or effect, and sometimes even causes chicken poisoning to die. Therefore, when purchasing a feed yeast, the majority of breeding professional households must widen their eyes to understand the true and false, and prevent the purchase of counterfeit products with high quality and low price.
Look at feed yeast - generally powdery, mixed with plant-based feed, especially mixed with cake feed is mostly fine granular or flake.
The smell of yeast is unique to the smell of concentrated yeast. The high-quality feed yeast is placed in boiling water, and the unique odor is more intense. Counterfeit feed yeast generally has a lighter odor, or does not have this unique odor, and there is no odor change in boiling water.
Dissolve the fermented feed yeast in water and mix well. It is easy to suspend, has a lot of foam, and the foam disappears slowly. The fake feed yeast is placed in the water and either floats on the surface of the water, or it quickly sinks into the bottom of the water, and there is no foam, even with a little foam, it will quickly disappear.
