Impact of the Tirsana BSC energy supplement on the productivity of Ayrshire cows

Abstract

Nowadays, a new science-based approach to animal feeding is required to create conditions for the full realization of their potential with intensive use of livestock. This research was an experimental test that aimed to evaluate effective feed intake of energy supplements TirsanaBSC by high-yield Ayrshire cows in the transit period. As a result of the supplement application the daily milk yield increased during 100 days of milking cows. The amount of milk fat and protein increased as well. There was an increase in carotene, glucose, pyruvic acid in the blood of experimental cows and reducing non-esterified fatty acids (NEFA). Adding the supplement Tirsana BSC to the diet of highly productive Ayrshire cows improved the quality of their colostrum.

“…In the compound feed of the 2nd and 3rd experimental groups, the protein concentrate "Agro-Matic" was introduced with a decrease in other vegetable protein concentrated feeds. In the experimental groups with protein concentrate, the level of metabolic energy in the diets of experimental animals was at the same level [2,8,9].…”

“…Thus, one of the milk quality criteria is its suitability for further processing [1,11,13]. Similarly, the qualitative composition of milk is determined by genetic factors (type, breed, line) and at the same time depends on paratypical factors: age, lactation stage, type of feeding, season and climatic conditions [1,2,9,10].…”
