th day of lactation, the second from the 46th until 90th day of lactation, and the third group from the 91st day of lactation until the end of milk production. Cows in the dry period comprised the fourth group. The highest activity of AST was determined in the first production period, while enzyme activity in the second and third periods was higher than in the dry period. ALT activity showed a statistically significant increase from the 46 th day of lactation until the dry period, and activity in the second and third periods was statistically higher than in the dry period. GGT activity in the first production period and in the dry period was statistically higher in comparison with the second and third periods. Research results showed a significant influence of milk production and the dry period on the activities of examined enzymes in the blood plasma, and we can conclude that there is a need for constant monitoring of the described parameters during production.
Activities of AST, ALT and GGT in clinically healthy dairy cows during lactation and in the dry period.
