Застосування неорганічних та органічних сполук Со, Cu та Zn за їх недостатності у дійних корів

Abstract

The results of research of certain biochemical parameters of blood in dairy cows for the prevention of insufficiency of Co, Cu and Zn by inorganic and organic compounds of trace elements are presented. The purpose of the work – to investigate the state of individual biochemical parameters of blood in dairy cows when using inorganic and organic compounds Co, Cu and Zn to prevent their insufficiency. The research material was the blood serum of experimental animals, which determined the content of total protein and the percentage of albumin, total calcium content, inorganic phosphorus, aspartateaminotransferase (AST) activity, alanineaminotransferase (ALT), alkaline phosphatase (AP).For research on dairy cows of the first experimental group, together with the feeds of the main diet, a mixture of trace elements sulphates was fed in the following ratio of components (mg/100 kg body weight): CuSO4 – 50, CoSO4 – 5, ZnSO4 – 120. Animals of the second experimental group fed a mixture of methionates and lysinates of trace elements in the following ratio of components (mg/ 100 kg of body weight): CuMet – 15, CuLis – 15, CoMet – 1, CoLis – 1, ZnMet – 35, ZnLis – 35. Feeding the mixture of compounds of fragile microelements was carried out by mixing them with mixed fodder, once a day, for 60 days. The evaluation of the research results was carried out at the beginning and at the end of the experiment.On the background of the deficit of Сobalt, Сuprum and Zinc, clinically diseased animals have hypoproteinemia, hypoalbuminemia, hypocalcemia, increased activity of AST, ALT and AP, indicating a metabolic abnormality in cows and development of microelementosis. It was established that the use of chelated cheeses in the form of methionates and lysinates of scarce microelements had a better therapeutic effect compared to inorganic compounds. The result of the application of chelate compounds of trace elements was a possible increase in the content of total protein in the blood serum, fractions of albumins, total calcium, decrease in the activity of AST, ALT and AP.

Development of measures to improve milk quality and safety during production

“…Chelate metals (iron, copper, zinc and manganese) are activating agents of the functions of enzymes, hormones and vitamins. They take part in the process of blood formation, growth, reproduction and have antioxidant properties [31,32].…”
