EFFECT OF FEEDING TOTAL MIXED RATION (TMR) ON BLOOD PROFILES IN LACTATING COWS*

Abstract

Eighteen crossbred lactating cows were randomly selected for the experiment on the basis of live weight and milk yield. The animals were divided into three groups and allotted to three dietary treatments, viz.- T0, T1 and T2. Animals in T0 groups were fed by conventional method (concentrate and roughages fed separately) and feeding of animals in T1 and T2 were done in the form of total mixed ration, where the roughage: concentrate ratio was maintained at 40:60 and 50:50, respectively. The feeding trial was conducted for 120 days. Blood samples were analyzed at monthly interval. The concentration of blood glucose, total serum protein, BUN and serum creatinine did not differ significantly (P>0.05) among the experimental groups. Thus, feeding system did not have any significant impact on the constituents of blood.
