Abstract

Functions tricarboxylic acid and a cyclic fatty acid synthesis process is only possible under normal carbohydrate metabolism. It is therefore important to know the nature of the normal state of metabolism in the rumen and the reasons for its violations, and have the knowledge and skill in time to influence exogenous factors. Among the latter is particularly important metabolic engineering that by constructing the scale and speed of the cascade of reactions major transformations appropriate combinations of substrates and other effectors, yields on high–quality animals and productive effect.

The article presents experimental data on the effect of antibiotic feed additive monensin on metabolic processes in the rumen of calves and its productive effect. The results of carbohydrate metabolism studies with mixed populations of microorganisms rumen of ruminant animals of the additive ionophore expand the existing information about its role in the assimilation of nutritious diet substances, as well as complementary data on the features of influence on of intermediate exchange and productive effect of exogenous factors substrate–ergotropic complex that, in ultimately, it allows the construction of a significant acceleration of anabolic and achieve high levels of performance.

Research evidence that growing calves, especially when switching to vegetarian diet, supplements ionophore significant effect on scar of intermediate metabolism.

Feeding calves antibiotic feed additive monensin at a dose of 0.5 g/kg body weight per day, showing a measurable impact on the metabolic processes in the rumen, especially during the habituation of animals to the vegetation and in subsequent periods of feeding. This effect is primarily a change in the molar ratio of VFA (increase the molar proportion of propionate at the expense of acetate), and the average daily gain in growth by 10.4% (1037 against 939 g).
