Correction of some metabolic parameters in cows during the milking period with the help of a feed additive

The article is devoted to the assessment of changes in the clinical condition, hematological parameters, some biochemical blood parameters  reflecting  the  state  of  protein-carbohydrate metabolism in cows during the milking period, as well as the results of correction of this condition with a feed additive based  on humic acids "Fulvat".  The  article examines the physiological processes occurring  in  the  metabolism  of  cows  during  the newbody period  and  the period  of  separation, reflects the results of the studies conducted in assessing the dynamics and correction of the main critical indicators in hematological, biochemical blood parameters, as well  as  in  vital  changes  in  cows.  The  research  was  carried  out  using  modern  techniques, instruments and equipment. The object of the study was cows, 2-3 lactation of a black-and-white breed. All the animals were on tethered maintenance and a balanced diet. 2 groups were formed for research: experimental and control. The animals of the experimental  group  received  the  main  ration (OR)  +  the  feed  additive  "Fulvat"  for  60 days from the moment of calving; the cows of the control group were kept only on the main ration, without the use of additives in feeding. The feed additive was administered orally with the main diet, mixed with concentrated feed. The total time of observation of the indicators of homeostasis in animals was  60  days.  Studies  have  shown  that  the feed additive has a beneficial effect on erythropoiesis due to the presence of iron, cobalt, copper and other micro- and macroelements in the chemical composition, increasing the level  of  hemoglobin  in  the  experimental group on the 60th day of lactation by 19,7 %, reducing the  risk of developing  a ketogenic situation, increases the level of ionized calcium in the blood of animals, which in 2 times higher, compared with animals in the control group; normalizes the acidity of the scar  content  in  cows  of  the  experimental group and the preservation of the number of infusoria at the physiological level.
