Low intake supplement for non-pregnant beef cows
The objective with this work was evaluate the effect of level different of low intake supplements on body weight (BW) change, body condition score (BCS), intake, digestibility and protein microbial efficiency of non-pregnancy cow, crossbreed, with Nellore blood predominance and initial BW of 394.7±...
