Physiological status of cows when using the additive Lamarin Saldonum

Abstract

The article provides information about the effect of different doses of the bioactive additive Lamarin Saldonum on the morphological parameters and immunobiochemical status of highly productive cows. The experiment involved 40 mature cows of the black-and-white Holstein breed, divided into three experimental and one control groups, with a milk yield of 7,500 kg of milk for the previous completed lactation. It is found that the use of biologically active additive from Japanese kelp and milk thistle in the rations of highly productive cows stimulates redox reactions occurring in the body of animals, which is confirmed by an increase in the level of hemoglobin in their blood by 3.92-8.63% in the first and second months of lactation, and also in increase the number of red blood cells – by 4.47-9.17% in comparison with the control group. The positive effect of the studied supplement on the immunological parameters of animals, their protein and carbohydrate metabolism was also established, what is expressed in an increase in the level of total protein by 7.66-19.15%, it's albumin and globulin fractions by 11.15-16.91% and 15.40-25.03%, the amount of glucose by 19.12-29.60%, and level of total immunoglobulins by 7.66-13.51%, as well as in a decrease in the values of alaninaminotransferase by 12.83-20.99% and total bilirubin by 25.09-43.54% in comparison with the indicators of animals in the control group. The best action of the additive is shown when it is used for 60 days in doses of 0.2 and 0.3 g/kg of body weight.
