Eighteen number of peripartum Karan Fries (KF) cross bred cows were selected. The animals were monitored post partum for reproductive parameters. Monthly body weight and daily milk yield of all animals were recorded. Wheat straw, maize, concentrate were fed to the lactating animals as per requirements of body weight and maintenance in the ratio 50:50 @ 8kg/animal. Blood samples were collected once a week for the analysis of plasma IGF I, Haptoglobin and Lactoferrin. The KF animals suffering from reproductive problem metritis were grouped separately. The metritic group was supplemented with fermented yeast culture @ 24g/animal/day. Each group had its own control. On supplementation of yeast culture the plasma Haptoglobin level significantly decreased and decreased further during supplementation and antibiotic treatment period (P<0.01). The concentration of plasma lactoferrin increased during the period of supplementation but decreased further on rendering antibiotic treatment. The concentration of plasma IGF I increased (P<0.01) during the entire period of supplementation. On supplementation even though concentration of inflammatory marker declined it could not cure cows from metritic condition and these animals could not conceive.
