Resumo
The objective of this study was to evaluate the effect of supplemental feed on postweaning performance of Pelibuey x Blackbelly ewe lambs managed under grazing conditions. Twenty eight Pelibuey x Blackbelly female lambs were assigned to one of two treatments: 1) low feed supple-mentation: 0.18 Mcal of metabolizable energy (EM) lamb-1d-1 and 10.5 g of crude protein (PB) lamb-1d-1 and 2) medium feed supplementation: 0.54 Mcal of EM and 31.6 g of PB lamb-1d-1, offered during 70 days. The supplement feed did not affect (p>0.05) body weight and average daily body weight gain (GDP). It is concluded that in grazing Pelibuey x Blackbelly ewe lambs the medium feed supplementation did not improve the daily body weight gain with respect to a low feed supplementation.
