Effect of lactation stages on biochemical entities of indigenous Badri cattle of Uttarakhand

The indigenous cattle of Uttarakhand, Badri is the first registered cattle breed of the state, mainly reared in Kumaon and Garhwal regions. The present study was carried out in forty healthy cows to evaluate the effect of lactation stages on biochemical entities.

Forty healthy animals were selected and divided into five groups with eight animals in each group during different stages of lactation viz. 0 to 60 days, 61 to 120 days, 121 to 180 days, 181 to 240 days and non-lactating animals. Blood samples were collected during different lactation stages and non-lactation period and serum was harvested. On each serum sample total protein, albumin, globulin, A: G ratio, urea, creatinine, glucose, cholesterol, triglycerides, HDL, LDL, calcium, phosphorus, Ca: P, total bilirubin, ALT, AST, ALP, GGT and CK were determined spectrophotometrically.

A significant effect of stages of lactation on serum total protein, albumin, glucose, cholesterol, triglycerides, phosphorus, Ca: P, ALT, ALP and CK was observed (p<0.05).
