The influence of "Helavit-A" mineral additives on the gain and the indicators of blood of the Kalmyk breed's young growth in the first months of life

The research objective was studying the influence of a feed mineral additive of "Helavit-A" on the organisms of the calves of the Kalmyk breed of meat direction. The research was conducted in JSC ‘Horse farm Berte’, Hangalassky area, the Republic of Sakha (Yakutia). The objects of the research were the calves of the Kalmyk breed from 20 to 30 days of age, 10 heads in experimental and 10 heads in control groups. The experiment was made during the winter and spring period for 1 month, the calves were kept together with cows mothers in the fastened keeping. In the morning after feeding the experimental group was given 5 ml of "Helavit-A" a head within 30 days. Every day live weight was measured and the condition of the animals was monitored. It was shown that use of feed additive helped to normalize trace elements in the intestines, to increase their appetite and average daily gain of live mass of the calves, to reduce the incidence of internal noncontagious diseases in young growth. Trace elements in helate, bioavailable form were a part of the preparation; it promoted effective assimilation of the preparation by the organism. The additive eliminated the deficiency of trace elements, normalized metabolism and increased nonspecific resistance of the organism. It was established that the gain of live mass of experimental group had been more, than in control for 10.2 %. The average daily gain of live mass of the calves at the end of the research made in the control group 584.4 g, in the experimental - 720.8 g a day. The decrease in the incidence of generally gastrointestinal and respiratory diseases in young growth was noted in the animals of experimental group. The blood test of the calves revealed that the inclusion in the diet of the calves of Helavit-A feed additive positively influenced physiological condition of animals.
