PASTURE AND HAYING USE OF HIGH-PRODUCTIVE GRASSES AND THEIR INFLUENCE ON THE PRODUCTION OF COARSE-WOOLED TUSHIN SHEEP
The rational use of natural mountain areas by native sheep breeds is a great reserve in obtaining high-quality sheep products that is urgent today. Experimental studies were carried out at the mountain station of the Dargavs hollow (village Dargavs, Prigorodny district, North Ossetia-Alania) with coarse-wooled Tushin sheep that were on the farm. For stationary experiments we selected typical ewes livestock and young Tushin sheep. Groups of animals were 10 heads each (control and test) according to the principle of pairs counterparts, taking into account the live weight and physiological state. Feeding conditions were different. The control group grazed on unimproved, unrestored natural pastures, the test one - on improved, fertilized with biological preparations, agro-ores and sheep manure. The green mass was received from experiment variants, and in the stall period hay harvested from fertilized plots. The indicator of food intake is the consumption amount. It was revealed that with increasing growth rate and the grass stand development under the influence of fertilizers, the consumption in all cycles decreases with the significant difference (td = 4.29-5.24). Young animals older than 6 months when growing for meat require 2.3-2.7 kg of dry matter per 100 g of body weight and 100-110 g of digested protein per a feed-unit. Body measurements can more change under the influence of improved feeding. At 2 months of age, the superiority of the experimental young animals was 13% more and at 4 months - 4.4%. The more intensive lambs development from ewes of the test group is explained by the increase in the biological milk quality. The amount of wool yield in both the physical mass and in the washed fiber of the animals in the test group exceeded their female counterparts by 4.7% in the physical weight and by 6.9% in the washed fiber.
