Inclusion of activated sea buckthorn oil cake and feed additive based on it in the ration of cows in the period of increasing the milk yield

Abstract

Simmental breed of cattle has a unique origin and is characterized by high plasticity and versatility, thanks to which it is widely distributed in many countries around the world. The reasons for the insuffi cient dairy productivity of cows in the farms of the Altai Republic such as the absence of their own breeding base since 2012, unbalanced feeding during the stall period, due to the low quality of bulky feed and a shortage of their own feed grain at high market prices for it. Therefore, it is obvious the relevance of studying the usefulness of feeding cows of the dairy herd of Simmental breed under the conditions of the Altai Republic and the development of targeted feed additives that contribute to a more complete realization of the genetic potential of dairy productivity, taking into account the peculiarities of the structure of the ration, contributing to the production of organic dairy products with increased biological value and optimal technological characteristics. The purpose of the work was to study the productivity traits of Simmental breed cows in the period of increasing the milk yield when feeding activated sea buckthorn oil cake and feed additive based on it. As a result of the use of activated fermented sea buckthorn oil cake and a feed additive based on it in feeding cows for 50 days of lactation, due to an increase in milk productivity and the percentage of fat and protein in milk, additional profit was obtained per 1 cow in the 1st experimental group of 1277,5 rubles and in the 2nd experimental group – 3064,5 rubles. The results obtained prove the eff ectiveness of the use of activated sea buckthorn oil cake and feed additive based on it in the rations of cows Simmental breed.
