[Carbohydrate content and glycolysis enzymatic activity in the liver of young purebred and hybrid cattle of both sexes].
It is established that the content of glycogen, glucose, fructose and the activity of phosphoglucomutase and phosphogexoisomerase is considerably higher in the heifer liver and the content of pentoses of adenylic system and the activity of aldolase is essentially lower than in the liver of bulls of the same breed. In the liver of growing hybrid young cattle (except of the Hereford heifers) as compared to the purebred ones the value of the total pentoses: glycogen and pentoses of adenylic system: glycogen ratios are significantly higher. These values in the bull liver of all the breed groups are essentially higher than in the heifer liver. The data obtained evidence for possibility of applying the values of ratio of total pentoses and especially of pentoses of adenylic system to glycogen as well as the activity of aldolase in the liver tissue as biochemical test for estimating the high rate of growth and prognosing the meat productivity of young cattle of different sex.
