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 lambs always were heavier (P<0.05), had higher fat depth and rib eye area than twin female lambs but there was no difference (P>0.05)
in these traits for female lambs born to R or NR ewes. There was no difference in the percentage of ewes cycling or their ovulation rate during the first breeding season of female lambs born single or twin neither of female lambs born to R or NR ewes. Ewes restricted at 60% of their ME requirements in mid-gestation seems to have the capacity to compensate any detrimental effects on lamb growth and development as well as the reproductive potential of female lambs if adequate refeeding conditions are provided in late gestation, throughout lactation and postweaning.
