It is estimated that each animal or bird needs about 110 g of protein per feed unit. That's just for today, the amount of protein per unit of finished feed is 85 g on average. This is very small, so there are a variety of problems with productivity. To increase the rate of protein in the diet and use dry fodder yeast.

The main value of this dietary supplement is the abundance of protein in the composition. With the regular introduction of additives in food, the nutritional value of food increases. It is much better absorbed, it helps in the winter, during the deficit of micro and macro elements, vitamins. Feed yeast, among other things, improves metabolism, reduces feed consumption.

Feed yeast will be useful for laying hens, and for those females that hatch and raise offspring, and even broilers, roosters. When using increases fertility of eggs and hatchability of young stock by 10-15%, and also egg production increases. Egg size and quality are also improving.
  • Adding fodder yeast to the diet of geese and ducks increases the fertility of eggs and hatchability of the young. But for this you need 14 days before the egg-laying to start the application of feeding. On average, the head takes 15 g / day. During the entire laying period, it is desirable to produce yeast, but this is especially important in the initial period.
