Haemato-biochemical profile of Corriedale ewes in relation to winter housing and feeding interventions in Kashmir region

A study was conducted to evaluate haematological and biochemical profile of pregnant ewes under different feeding and housing interventions during winter in Kashmir. Forty healthy Corriedale ewes in their third month of gestation were selected randomly and allotted to four groups (G1, G2, G3 and G4) of 10 animals each such that the parity and average body weight differences between the groups were statistically non-significant. Ewes of G1 and G3 were kept inside the shed while as G2 and G4 were kept in an open area which was wire fenced from four sides and provided with a roof shelter. G3 and G4 were supplemented additional pelleted concentrate @ 100g/head/day in addition to the basic ration. The blood samples were collected on the first day of the trial, post-parturition and at the end of the trial. Among the haematological parameters, haemoglobin and packed cell volume were significantly (P< 0.05) higher in G2 and G4. G2 and G4 had significantly (P< 0.05) higher neutrophil but lower lymphocyte count. Among the bio-chemical parameters, plasma glucose, total protein, triglyceride, triiodothyronine, thyroxine and cortisol levels were significantly (P< 0.05) higher in G2 and G4 while as cholesterol levels were non-significant among the groups. It was concluded that the experiment did not result in any adverse effect on the health state of the ewes as evidenced by the results which can provide an economic advantage for producers by reducing the cost associated with the construction of elaborate housing.
