a,bValues containing different letters in each row are significantly different (P < 0.05)
- P1 = control without phosalone and sodium bentonite (SB); P2 = phosalone given at dose of 280 mg/day/ewe; P3 = phosalone (280 mg/ewe/day) and SB (32 g/ewe/day) fed for 63 consecutive days; Treatment P4 = feeding SB with concentration of 32 g/ewe/day
