Abstract

This research was conducted from two studies with beef heifers grazing submitted different supplementation strategies and the results are here presented in two manuscripts. In the first manuscript, effects of supplement amounts on productive and nutritional performance and metabolic profile were evaluated in suckling female calves under grazing in the tropics. The treatments were 1) 4 g/kg body weight (BW) of supplement or 2) 6 g/kg BW of supplement. Forage and organic matter (OM) intake did not affect (P>0.12) by amounts of supplement, though crude protein and non-fibrous carbohydrates intake were greater (P0.23) the amounts of supplement on OM and CP digestibility. In addition, production of microbial nitrogen was similar (P>0.15) between...
