Влияние гепатопротектора ZIGBIR® на организм стельных сухостойных коров

Relevance. ZIGBIR ® feed additive, consisting of a set of plants that affect the state and recovery of hepatocytes, is unique and is of interest for research. As a result of the experiment, the feasibility and effectiveness of using the plant feed additive ZIGBIR ® in the diets of pregnant dry cows was studied. Its effect on the absorption of nutrients in the diet, biochemical parameters, the safety of young animals and gynecological diseases is shown. Methods. The experimental part of the work was carried out in the Agricultural Cooperative “Named after Ilyich” of the Novgorod region on cows of the dry period. According to the principle of analogs, three groups of animals were formed — a control group and two experimental ones ( n = 10 in each) from cows that were in the run taking into account the dates of the planned calving. The animals of the first experimental group, in addition to the main diet, received a feed additive ZIGBIR ® in the amount of 20 g/head/day, the second experimental group — 25 g/head/day. Results. As a result of scientific research, it was found that groups of cows that received a feed supplement in addition to the main diet were better able to absorb nutrients. So the coefficient of dry matter digestibility in the first experimental group increased by 0.9%, in the second — by 0.4%. A similar increase in the digestibility coefficients was observed for organic matter (by 1.7–8.3%), crude protein, crude fat, BEV and crude fiber. The introduction of the supplement into the diet did not lead to a deterioration in biochemical parameters. For example, the value of the protein index (the ratio of albumins to globulins), indicating the intensity of protein metabolism, in the control group was 0.66, and was below the physiological limit by 27%. However, in both experimental groups its indicators increased and almost returned to normal with values of 0.9 and 0.8 respectively. The reduction of postpartum pathologies and the increase in the safety of young animals suggests the therapeutic effectiveness of the ZIGBIR ® feed additive.
