Hematology the study of blood composition of dairy cows in the application UVMK «Hazine-lick»

Abstract

 In intensive conditions of keeping animals without the use of additional top dressing, premixes, biologically active additives, it is almost impossible to achieve maximum productivity of animals. Important the reason for this is metabolic disorders. As a result of metabolic disorders in animals, the  immune status of the body decreases, as a result of which they become susceptible to various diseases, reduced fertility, the birth of weak offspring, reduced productivity, etc. Therefore, modern technologies of feeding farm animals, provide for the active use of premixes and other biologically active  substances to the main diet. The purpose of this study was to study the hematological composition of the blood of dairy cows when using the UVMC "Khazine-lizunets". It is known that the indicator of metabolism in the body of animals is blood. It constantly circulates in a closed system of blood vessels and performs a transport, protective and regulatory function in the  body of animals. For this purpose, we conducted experiments on clinically healthy dairy cows of the black-and-white breed in the conditions of the farm of LLC "Igenche" of the Tyulyachinsky district of the Republic of Tatarstan. In the experimental animals,  the general clinical condition, the amount of feed intake, the lizun and the state of hematological blood parameters were evaluated. It was found that the use of UVMC "Khazine-lizunets" in dairy cows at the stage of milking at a dose of 181,2±0,47 g per day for thirty days has a positive effect on their hematological parameters of blood composition. It was found that in animals, when using this feed additive, the feed consumption increases by 3,5%. There is an improvement in the clinical condition of the body, due to the content of vital nutrients in the composition of the UVMC "Khazinelizunets". It was revealed that the  hematological parameters of the blood were within the physiological norm.
