Energy supplements impact on the metabolism level in the cows body in the milking period

The purpose of research is to study the effect of energy supplements from different manufacturers on the totality of chemical and physical transformations that occur in the body of cows during the milking period. The experiment was carried out at CJSC Glinki in the Kurgan Region. The object of the study were black-motley cows, which, according to the principle of analogues, were formed into three groups. During the experiment, the cows of the control and experimental groups received a diet consisting of 34.5 kg of feed mixture; 4.0 kg of rump hay; 1.7 kg of rapeseed cake; 1.0 kg of crushed corn; 5.0 kg of fresh spent grains; 0.5 kg BVMK-60-10 and 0.5 kg feed molasses. In addition to the basic diet, the cows of the 1st experimental group were fed the energy supplement Lacto C in the amount of 200 g/head/day, the 2nd experimental group - the energy supplement Extima 100 at a dose of 200 g/head/day. It was established that the introduction of the energy supplement Lakto S into the diet of cows favored the absorption of the following nutrients of the diet feed: dry and organic matter - by 3.57-2.09 and 3.35-2.02 %; crude protein - 4.12 (P function show_eabstract() { $('#eabstract1').hide(); $('#eabstract2').show(); $('#eabstract_expand').hide(); }
