Lately, more and more often to stimulate the reproductive function of animals people use biochemical products, which are based on neurotropic and metabolic compounds and trace elements of nanobiotechnological origin. In order to new biotechnical drugs search and development, and more effective and safe combinations of dietary supplements in them, one should know Biochemical mechanisms of membranotropic action of these substances on a cell. Since these substances can lead to physiological changes in the cell and trigger nonspecific toxic effects on the body of animals depending on dose and period of action. The article presents the results of studies on the effects of neurotropic and metabolic drugs on structural and functional state of lipid matrix of the cell membrane.
Signs of impending calvingin beef cows under various feeding and housing conditions
(НУБіП України, 2019) Ugnivenko, A.N.; Bondarenko, G.P.; Nosevych, D.K.; Demchuk, S.Yu.
Research data on the signs of impending calving in late pregnant cows of Ukrainian beef breed under various systems of housing and feeding are presented in the paper. Tie stall housing provides for earlier development of calving signs in cows three weeks prior to calving. Cervical plug is dissolved 5,1 days prior to calving, dilatation of pelvic ligaments occurs at 3,1 days before calving, udder edema – 5 days, vulva extension – 7,5 days prior to calving. Those signs develop later in grazing conditions. Cervical plug is dissolved 2,0 days prior to calving, dilatation of pelvic ligaments occurs at 2,3 days before calving, udder edema – 2,5 days, vulva extension – 0,9 days prior to calving. As compared to cows, heifers develop calving signs earlier.
