摘要: This experiment was conducted to evaluate the effects of pre and postnatal feed restriction on growth production Santa Ines lambs from weaning slaughter. Forty-eight were assigned three treatments as follows: with prenatal (PRER), (POSTR), no (Control). Average daily intake (as fed basis) POSTR treatment (624 g/d) significantly lower (P<0.05) than that control (757 PRER (765 possibly because after birth. However, total lowest control, which may be explained by earlier slaughter age in this compared feed-restricted animals. Daily weight gain non-restricted (Control) averaged 257 g/d greater POSR 155 198 g/d, respectively. Lower indicated animals not able compensate imposed leading later higher consumption.
