Contenido :  ABSTRACT The aim of the study was to evaluate maternal energy restriction in ewes from day 48 to 106 of gestation on pre- and post-weaning lambs` performance, onset of female lambs? puberty and ovulation rate when their dams were fed ad libitum after the restriction period. Ewes bearing single or twin lambs were assigned to two dietary treatments from day 48 to day 106 of gestation: restricted (R; n = 60) at 60% of their metabolizable energy (ME) requirements, or non-restricted (NR; n = 54) at 100% of their ME requirements. After the restriction period ewes grazed all together ad libitum until weaning. Ewes body weight was recorded during nutritional treatment application and at weaning. Litter size and lamb sex were recorded. All lambs were evaluated together from birth until weaning. One month after weaning, female lambs were further evaluated during their first breeding season where it was recorded their liveweight gain, fat depth, rib eye area, onset of puberty, ovulation rate (number of corpus luteum/total female lambs with corpus luteum). Non-restricted ewes weighed 7.5 kg more than R ewes (P < 0.05) at the end of the restriction period. Lamb birth weight (BW) was no affected (P> 0.05) by dams? treatment although male and single lambs had a greater (P < 0.05) BW than females and twins, respectively. No significant differences (P > 0.05) were detected on the weaning weight between ewes? feeding treatments or lamb sex. During the experimental period, single born female l... Presentar Todo
