The research was carried out in 2019 at the “Balahovit” teaching-experimental farm of the Armenian National Agrarian University on the three-breed heifers with the ratio of 1/4 Caucasian brown, 1/4 Jersey and 1/2 Holstein genotypes. The growing and development indices of the experimental heifers have been much higher than those of the control group. Feeding profitability for 1 kg weight growth has made 10.8 MJ and 394 g digestible protein, while the same indicators in the control group are 29.4 MJ and 623.6 g.
So, it is recommended to apply the feed ration developed, tested and currently used at the “Balahovit” teaching-experimental farm in the livestock farms of Armenia for raising neonatal heifers.
