The black-and-white cattle blood morphological status when using phytoadaptogens

The purpose of research is to study the morphological composition of the blood of heifers, no - calf heifers and first-calf heifers of the black-and-white breed using phytoadaptogens from regional raw materials. As phytoadaptogens, an extract of cranberry meal containing 40 % ursolic acid, obtained at the Novosibirsk Institute of Organic Chemistry named after N.N. Vorozhtsov SB RAS, dry extract of Rhodiola rosea with up to 3 % glycosides-salidrosides. The object of research is heifers of black-and-white breed (n=30), after fruitful insemination - heifers, after giving birth - cows - first-calf heifers. For research, 3 groups of animals were formed: control (n=10), 1st experimental (n=10) and 2nd experimental (n=10). Animals of all groups were kept separately in group cages, in accordance with the characteristics of feeding, according to a loose-box system. The control group of heifers was fed the main diet in the form of a haylage-concentrate feed mixture, the heifers of the 1st experimental group additionally received cranberry meal extract containing 40% ursolic acid at a dose of 250.0 mg per head for 20 days before insemination; 2nd experimental group of heifers - a two-component composition of the same amount of cranberry meal extract and 200.0 mg per head per day of dry extract of Rhodiola rosea; heifers were fed drugs for 10 days at 3 and 7 months of pregnancy; first-calf heifers - immediately after calving for 20 days. The use of phytoadaptogens 20 days before the insemination of animals, during pregnancy and immediately after calving helps to increase the adaptive capacity of the body by increasing the respiratory capacity of the blood - the number of erythrocytes and hemoglobin, and stabilizing the body's reactivity. A more pronounced reaction of the body was noted when using a two-component composition of phytoadaptogens.
