Digestibility and utilization of rations' nutrient substances by remount heifers at the various levels of mineral nourishment

The author estimates the digestibility of different nutrients of food and nitrogen assimilation by heifers of the Black-and-White breed in the connection with animals age and equilibrium of the rations on mineral elements. It was shown, that optimal content of mineral elements in the rations promote to digestibility of all nutrients in food and increase the nitrogen deposit in the heifers body, that accelerate their growth and development and make better the animals health.
