Studying the growth and development of hybrids cows

The research was carried out at the training center for animal husbandry and horse breeding of the Azerbaijan State Agrarian University. Several breeds of cows have been studied. At the age of 6 months, the average weight of the representatives of the Simmental breed was 175 kg, Holstein - 163 kg, Simmental × Holstein - 171 kg, Aberdeen Angus × Holstein - 178 kg, Charolais × Holstein - 176 kg and Zebu × Simmental - 192 kg. The aim of the study was to determine the genotype with the optimal result of growth and development. As a result of feeding, the weight gain from birth to 6 months was: Simmental - 761 g, Holstein - 716 g, Simmental × Holstein - 750 g, Aberdeen-Angus × Holstein - 833 g, Charolais × Holstein - 804 g and Zebu × Simmental - 844 g. As a result, it was concluded that a balanced diet has a positive effect on the dynamics of growth and development of all the studied breeds.
