Milk Productivity and Hematological Parameters of Cows During the Period of Increasing the Milk Yield With the Use of Dry Protected Fat-Based Energy Feed in the Diet

Abstract

The use of “protected” fats in feeding cows provides the animals with the necessary amount of energy. One of the most guaranteed sources of energy in diets and feed mixtures of cows are rapeseed products. The article presents research materials, the purpose of which was to establish the effect of a complex energy feed based on dry protected fat as part of rations for dairy cows during the period of increasing the milk yield on milk productivity and hematological parameters. Studies showed that the inclusion of energy feed based on dry protected fat in the diet of experimental animals in the amount of 3% by weight of the compound feed contributed to an increase in milk productivity by 8.1% and had a positive effect on hematological parameters.
