The dynamics of the concentration of insulin in the blood of a heifer of different breeds

Abstract

Purpose : to study the dynamics of insulin in different periods of the flow of different breeds: a golstinized black-and-haired, Simmental, Aberdeen-Angus and Knieuted Netele (Simmental X Aberdin-Anguskaya). Materials and methods . The object of research was not there was a golstinized Black-and-white, Simmental, Aberdin-Anguskaya and crossbreeds (golstinized Black-and-white x Simmental) in each group in each group. Explust animals were grown in the same conditions. During all periods of experience, Kalles took blood samples until morning feeding. In blood samples, the level of insulin was determined by the immunofortment method. The level of feeding of the heels corresponded to the zootechnical norms. Results . Before insemination, the level of insulin in black-and-chilled heifers was 11.0 ± 0.5, in the Simmental-12.1 ± 0.6, in Aberdin-Angus-12.8 ± 0.6, in the combed-13.1 ± 0 , 7 μma/ml. In the future, with an increase in the duration of animals, the concentration of this hormone in the blood increased and by the 5th month the concentration of insulin was noted as the maximum for the entire period. In black-and-playing, in this period, the level of insulin increased to 12.3 ± 0.6, in the Simmental to 13.0 ± 0.8, in the Aberdine-Anguski to 14.1 ± 0.7, in Monnie, up to 14, 4 ± 0.7 μm/ml. By the end, the level of insulin in the blood of the miles was significantly reduced in black-and-playing noles by 9 months of age, it was 10.2 ± 0.6, in the Simmental-10.5 ± 0.7, in the Aberdine-Angus-11.4 ± 0. , 7, in the Knieut - 12.6 ± 0.7 mkm/ml. In all periods, the relatively low level of insulin was marked by black-festivities in relation to the compared breeds: Simmental, Aberdeen-Anguska and Knight Netel.
