ATPase Activity in Red-Blood and Muscle Tissue Cells in Sheep

Аннотация

The objective of the survey is to identify the specificities in the functions of ATPase enzyme systems in blood and the longest back muscle in sheep of two breeds and different ages. Lambs and wethers of Texel and Kuibyshev breeds sampled on the analog principle are the subject of the survey according to the current animal-keeping and feeding standards developed by the Ernst All-Russia Research Institute for Animal Husbandry. It has been ascertained that the activities of Mg²⁺, Na⁺, K⁺-ATPase, Mg²⁺-ATase, and Na⁺, K⁺-ATPase in the lamb’s red-blood cell membranes are determined by the age at high significance levels (P  < 0.001) of 99.45, 99.41, and 98.46%, respectively, while their activities in the wethers’ longest back muscle are determined by the age at the levels of 81.09, 85.16, and 83.21%, respectively. The correlation analysis has proven the effects of age on the ATPase activity in the membranes of the red blood cells and the longest back muscle сells. With respect to red blood cells, the correlation is negative, while the muscle tissue is found to have a positive correlation. No significant effect of the breed specificity on the activities of Mg²⁺, Na⁺, K⁺-ATPase, Mg²⁺-ATPase, and Na⁺, K⁺-ATPase in the red-blood and muscle tissue cells was identified.
