The effect of Vetom 2 on the velvet antler productivity of maral stags

The purpose of research is to study the effect of the drug Vetom 2 on the antler productivity of stag deer. The studies were carried out at the Abinsk maral farm Novotalitskoye Experiment Station, Federal State Budget-Funded Scientific Institution Federal Altai Scientific Centre for Agrobiotechnologies in the spring of 2022. In the process of performing the work, generally accepted zootechnical research methods were used. From the available livestock, two groups were distinguished - control (K; n=10) and experimental (O; n=10). The stags were kept separately in different winter stalls. Deer stags of the control group received the basic diet (BD). Vetom 2 was included in the diet of the experimental group in a prophylactic dose at the rate of 50 mg/kg of live weight. The selection of animals for the experiment was carried out by the method of groups-analogues by age, level of development, constitution, state of health and other qualities. The physiological state of the experimental animals was determined by the activity and the course of moulting, bottom piece shedding and the beginning of velvet antler growth. Accounting for velvet antler productivity in velvet-antler marals was carried out during the antler-cutting campaign on the farm according to the grading scale, distinguishing the livestock of the control and experimental groups according to the inventory numbers on the tags. In the experimental group of stags, an improvement in the physiological state was noted, the marals were more active, the spring molt passed almost simultaneously. Bottom piece shedding in all stags that received Vetom 2 in their diet ended earlier by an average of 2 days. In the stags of the experimental group, an increase in the concentration of erythrocytes by 23 %, hemoglobin by 8% was recorded. A slight decrease in the total amount of protein (4 %) and albumin (10-16 %) was noted, while they do not go beyond the reference range. An increase in calcium concentration by 22 % in the stags of the experimental group by the end of the experiment had a high degree of reliability. There was a superiority in the mass of raw velvet antlers per 150 grams in the experimental group compared to the antlers of the control group, but this value is unreliable between the compared groups.
