| description | The results of the study conducted at the “Pchany-Denkovych” stud farm of the Stryi district of the Lviv region on heifers of the Simmental breed obtained from cows with different productivity are described. The dynamics of animal growth and the biochemical composition of the blood of heifers obtained from low-productive and high-productive mothers were studied. In the process of studying the dynamics of the live weight of calves from birth to 6 months of age, a tendency to increase the body weight of calves of the first group, obtained from highly productive mothers, at the age of 2, 4, and 6 months, respectively, was established – by 1.2 kg, 5.3 kg and 4.8 kg to the body weight index of heifers obtained from low-yielding cows. Experimental groups of heifers at the age of 6 months corresponded to the live weight of the Simmental breed standard. It was established that the total protein content in the blood serum of heifers obtained from cows with different milk productivity from birth to 6 months of age was within the physiological norm and increased gradually with the advantage of its level in analogs obtained from highly productive cows. Comparing the indicators of total protein in the dynamics from the first to the sixth month, it was found that it increased by 33.9 % in the first group and 25.5 % in the second group, respectively. The level of total cholesterol in the blood serum of experimental heifers during six months increased with age, with a slight advantage of indicators in heifers from the first group, which came from highly productive mothers (Р > 0.05). The increase in total cholesterol from one month to 6 months of age in the first and second groups of heifers was 38.5 % and 20.0 %, respectively. A higher concentration of total lipids was noted in the blood of experimental daughters of highly productive cows. The minimum indicators of the level of total lipids were established in the first month of life of experimental heifers of the first and second groups, respectively – at 2.7 and 2.6 g/l, with the same level (3.5 g/l) in the second month and an increase in indicators in the third-month life (4.5 vs. 4.1 g/l) (Р > 0.05). It was established that the activity of aspartate aminotransferase in all periods of growth of Simmental breed heifers significantly exceeds the activity of alanine aminotransferase. Characteristic features of the dynamics of this indicator are the maximum activity of AST and ALT in the first two months of the animal's life, which then gradually decreases. |
