ABSTRACT
The aim of the study was an assessment of an influence of glycerin applied to the TMR dose on carbohydrate-lipid transformations, chosen enzymes activity and milk yield of Polish Holstein-Friesian cows in periparturient period. 24 multiparous cows were included in the research. Glycerin in a dose of 300 ml /day was applied to the TMR dose of the experimental cows from 7 day a.p. to 3 week p.p. Biochemical tests of blood were conducted using Pentra 400 analyzer of HORIBA ABX Company. The concentration of glucose, β-betahydroxybutyrate acid, unsaturated fatty acid, triglycerides, total cholesterol, AST, ALP, GGT enzymes activity as well as total bilirubin was determined in blood serum. The long-term feeding of glycerin in periparturient period had an antiketogenic effect limiting glucose level decrease in blood, and limited an intensification of lipolysis at the beginning of lactation. The lower increase of AST activity and total bilirubin concentration was affirmed at 3 week p.p., after the use of glycerin. The lower decrease in condition was noted in experimental cows, that did not influence statistically on milk yield.
Key words: cows, periparturient period, glycerin, blood, metabolic profile.
