Morphobiological features of buck lambs by using high protein extruded food

Abstract

The development of internal organs and the morphological composition of carcasses of the sheep’s ox of Volgograd breeds when feeding them grain extruded forages with the use of dry beer pellets (EKKO-PD-SM) and pumpkin cake (EKKO-PC-SM) in combination with natural sulfur and methionine. Studies have established that sheep of experimental groups by the mass of internal organs were superior to the peers of the control group. Thus, the animals of the I and II-experimental groups had an advantage in comparison with the control peers: by weight of the leaked blood 9.24 and 11.54% (P ˂ 0.05); by weight of heart 12,41 and 16,47% (Р ˂ 0,05); by weight of lungs 8.60 and 11.34% (P ˂ 0.05); by weight of the liver 8,40 and 10,93% (Р ˂ 0,05); by weight of spleen 22,06 and 24,11% (Р ˂ 0,05) respectively. By the mass of the kidneys, there is no reliable difference in the compared groups, although the tendency of its increase in the animals of the experimental groups was noted. Buck lambs of I and II-experimental groups exceeded the control peer by weight of the stomach without contents by 8.04 and 10.57% (P ˂ 0.05), by weight of the small intestine by 9.07 and 12.29% (P ˂ 0.05), by weight of carcass (by 10.78-14.66%), by weight of pulp (by 17.19-22.81%), respectively.
