Blood lipids profile in lactating cows fed with supplement of OVOCAP®

This study was conducted to test the effects of feeding supplemental Bulgarian nutritive additive OVOCAP® administrated per os, on blood lipid profile in lactating cows. Twelve lactating American Brown cows (BW = 695 ± 28 kg; at the beginning of the lactation) were separated to two treatments for 1,5 year. Cows were fed typical diets during the winter (corn silage, meadow hay, straw, wheat bran, potatoes and compound feed) and summer (pasture and compound feed). Experimental cows received in addition to concentrate part of their daily ration 2x23 ml OVOCAP® each every 28 th day in the month, first doses being on the 3 rd and 4 th day post partum. Blood samples were collected after every giving doses of OVOCAP®, morning before feeding and sera were analyzed for triglycerides, HDL, LDL, VLDL and total lipids concentration. Feed intake was similar in the two groups. Observed levels of the HDL cholesterol were significant lowered (P≤0,05) under the influence of OVOCAP®. Observed levels of LDL and VLDL cholesterol as well as triglycerides and total lipids were significant lowered (P ≤0,001) under the influence of OVOCAP®. This results suggest that OVOCAP® may posses hypocholesterolemia and hypotriglyceridemic effect in lactating cows. This experiment demonstrated that OVOCAP® is adjusted to use in lactating cows with sure definite benefit on blood lipoprotein profile.
