The method of normalizing the energy metabolism of cows in the postacute period

The aim of presented work was to investigate whether energetic metabolism of cow in the after calving period could be normalized by using new approach which provides stimulation of gluconeogenesis and optimal functioning of citric acid cycle. For realization of the approach it was proposed to introduceinto ration of cows, in the form of mixture-stimulator of energetic metabolism, such gluconeogenesis substrates as pyruvate, phosphoenolpyruvate and all other compounds present on the way of glucose synthesis and also number of compounds known to stimulate synthesis of main citric acid cycle component- oxaloacetate namely methylmalonyl-CoA mutase and pyruvate carboxylase co-factors and glycogenic amino acids. To test the approach, mixture was fed to the animals in experimental group in the composition of total mixed ration in the dose of 250 g/head/day starting after calving and up to 30 days of lactation. Within six month of trials on the basis of «Gomontovo» farm 700 cows have participated in the experi ment. To estimate approach efficiency number of cases of diseases associated with metabolic disorders was analyzed. Statistical data obtained before beginning of described trials in 2017 for after-calving cows was used as control. As a result of performed research it was shown that application of provided approach leads to the decrease of ketosis cases on 55%, abomasum displacement on 70% and hard digestion disorders on 53%. In accordance with obtained results mixture-stimulator of energetic metabolism was introduced to the feeding schedule of «Gomontovo» farm in the permanent manner.
