Abstract

Purpose: The study of the dynamics of insulin in the blood of growing heifers of different breeds.Materials and methods. The object of the study were heifers of the Calledinized Black-Black-Avoid, Simumal, Aberdeine-Anga and brown heifers obtained as a result of the intersection of Simmental х Aberdine –angus rocks in each group. The study of animals was grown in the same conditions. Blood for the study of insulin was taken from the tail vein until morning feeding at birth, aged 3, 6, 12 and 15 months. Weighing experimental animals was also carried out at the indicated time.Results. At birth, the golpinized black festival, simulars and place-codes in live weight significantly exceeded the peers of Aberdin-Angus. The differences in relation to Aberdin-Anguss were statistically reliable (p_ 0.05). At the age of 15, due to the black and qualified breed, statistically reliable differences at this age were noted in Aberdin Anges and Montflowers (P<0.05). Statistically reliable differences (P<0.05) were also noted between the five property and Simmental. The average daily growth of blacks and pollen from birth to 15 months was 875.7 g, in the Simmental 902.1 g, in Aberdina-Angus 911.7 g, for estates of 947.5 g. The level of bloodshed at birth was almost the same in all in all animal breeds. Thus, in black heels it was 7.4 ± 0.5, in Simmental-7.2 ± 4.4, in Aberdine-Angas-7.0 ± 4.8, in estates-7.2 ± 3.4 MKM/ml. By 3 months, the level of insulin increased in all experimental groups of heifers. In the future, with an increase in the age of the animals, the concentration of this hormone in the blood has not changed. At the age of the 3rd and 6-month age between the heifers of the simultaneous, Aberdin-Angus, animals, as well as breeds with black sand, a statistically reliable difference is established (P<0.05). In the future, under the age of 15 months, the concentration of insulin in the blood changes illegally, but it should be noted that a relatively low concentration during all growth periods was noted in the heifers of the black and qualifying department of the breed.
