Serum Biochemical And Enzymatic Studies During Different Stages Of Pregnancy In Cows

Serum biochemical and enzymatic profile of 20 cows in three different stages of pregnancy and non-pregnancy (control) was studied. The serum glucose values (mg/dl) obtained for the first, second and third trimester of pregnancy and in non-pregnant animals evinced a significant difference (p<0.05). The total protein concentration did not reveal any significant variation between groups. The serum cholesterol values differed significantly (p<0.05). The serum ALT value (U/L) at 3rd trimester was significantly higher than the values at 1st and 2nd trimester and in non-pregnant group of animals. AST activity (U/L) also differed significantly.
