Sustainable Increase of Cow Milk Productivity Using Components of Siberian Forest and Alpha-Amylase Enzyme
1Krasnoyarsk Research Institute of Animal Husbandry - Separate Division of the Federal State Budget Scientific Institution “Federal Research Center “Krasnoyarsk Science Center of the Siberian Branch of the Russian Academy of Sciences”, 660049, Krasnoyarsk, RUSSIA DOI : 10.9775/kvfd.2020.24102 At the places of harvesting coniferous trees and industrial nuts processing remains, a devastating amount of wastes litters large areas of land, poisons the air and the hydro-environment by the combustion products and toxic compounds released during decomposition. Therefore, the search for solution for the effective use of waste is an actual task. The aim of this research is to investigate the influence of fodder additive made of forest waste resources and the enzymes on milk productivity of cows. The experiment has been held on black-and-white breed in Krasnoyarsk region. The experimental group received, in addition to the main diet, some fodder additives consisted of coniferous flower, crushed pine nut shells, arabinogalactane and amilosubtiline HCl enzyme. The analysis of coniferous flower demonstrated that it contains more copper by 41.6%, zinc-55.6%, magnesium-183.3%, chromium-66.7% than in pine nut shell thus, on the contrary, the content of lignin, cellulose and moisture, was more in the shell of pine nuts-24.2%, 9.7% and 5.0%, respectively. Under the effect of the test additives in cows of the experimental group milk yield was higher than the control group, 9.9% (P<0.05), fat mass fraction - 0.3% (P<0.05), the amount of milk basis of fat content 19.0%, in the blood was higher total protein content 2.7%, glucose - 4.0; albumin - 3.0; - creatinine 6.0; triglycerides by 11.1%; calcium 1.5%; phosphorous - 10.2; iron - on 3.6%, magnesium - 2.6%. Thus, the tested additives had a positive synergistic effect on the body of cows, which affected the increase in the quantity and quality of milk.
