The effectiveness of the use of natural mineral feed additives in the cultivation of young sheep

Abstract

Aim. The effectiveness of the use of the mineral feed additive bischofit in the diets of young sheep in the South of Russia at various doses and its impact on the productive qualities of young sheep. Materials and Methods. The material for conducting the experiment in this household was the livestock of sheep of the Grozny breed on fattening. The sheep of the control group received a basic household diet, the I experimental group received 5 ml of bischofite per head per day in addition to the main diet, the II experimental group received 8 ml of feed additive. Classical zootechnical methods were used in the process of work, including wool yield and physical and technological properties were studied individually in 3 experimental animals from each group according to the VNIIOK method. The research materials were processed by the methods of variation statistics using the Microsoft Office software package. Results. Young sheep from the I experimental group, who received bischofite at 5 ml / head per day, were 9.4% more in live weight than in the control group. Young sheep that received 5 ml of feed additive had the best meat index, and exceeded the control group in terms of pulp yield by 12.5%. The maximum deviation from the average value of the cut of pure wool in the upward direction (110.6%) was observed in I experimental group. The most durable wool of 7.24 sN / tex is found in the group that received the bischofit feed additive as part of the main diet. Conclusion. To compensate for the lack of mineral substances of the natural and environmentally safe feed additive bischofit at a dose of 5 ml / head per day, it changes the metabolic reactions in the body in a positive way, which is confirmed by an increase in the growth of live weight and wool productivity.
