Total serum protein: In all the three sheep breeds included in the study, there was a gradual decline in the values of TSP (Table 3). Values of TSP remained different among three sheep breeds from 6^th to 9^th week post-exposure to contaminated pasture. The level of significance in difference increased with an increase in the level of infection i.e. FEC etc. The maximum reduction in TSP values was recorded in KM (1.4 g/dl) followed by BW (1.2 g/dl) and CD (1.0 g/dl) sheep
