| description | The article focuses on the assessment of morphological and biochemical parameters of blood in dynamics for 50 days of lactation against the background of the use in the diet of a complex of biologically active substances (BAS) with antioxidant properties, including the following components: feed sulfur, magnesium, copper, manganese, zinc, selenium, vitamins А, E, H, C and succinic acid. The experiment was carried out in two age groups of early post-partum cows: 2-4 lactations, 5 and more lactations. The influence of the studied complex on the character of involution processes in the genitals of early post-partum cows and the subsequent normalization of the reproductive function was analyzed. It is noted that the inclusion of the complex of biologically active substances into the diet of the experimental groups would reduce the number of white blood cells during the study period from 7.11 to 5.61*109/l (21%) in the first experimental group and from 6.60 to 6.33*109/l (4%) in the second experimental group, and lower aspartate aminotransferase activity from 115.00 to 72.50 U/l (36%) and from 79.33 to 60.33 U/l (24%) in the first and second experimental groups respectively, which further had a positive impact on reproductive performance. The duration of the period from calving to the first insemination was 3.7 and 6.7 days shorter in comparison with the control in the first and second experimental groups, respectively. The best result on fertilization of animals was achieved in the experimental group of 2-4 lactation cows, where the reduction of the service period and the interval between calving was 41 and 44.7 days, respectively. |
