چکیده انگلیسی
The effect of altrenogest (ALT) feeding combined with induced ovulation by human chorionic gonadotropin (hCG) in sows was evaluated on piglet birth weight (BW) variation and pre-weaning performance. Sows were divided into four groups: the control (no ALT; without hCG induction; artificial inseminated (AI) at 12 and 36â¯h after estrus; nâ¯=â¯40), ALTâ¯+â¯hCG72 (ALT 20â¯mg/d, D-4-D2 (D0: weaning day); hCG 750â¯IU at 72â¯h post ALT; AI at 24 and 40â¯h after hCG; nâ¯=â¯41), ALTâ¯+â¯hCG96 (ALT 20â¯mg/d, D-4-D2; hCG 750â¯IU at 96â¯h post ALT; AI at 24 and 40â¯h after hCG; nâ¯=â¯41) and ALTâ¯+â¯no hCG (20â¯mg/d, D-4-D2; without hCG induction; AI at 12 and 36â¯h after estrus; nâ¯=â¯41). The results revealed that piglet BW was not different among the groups (pâ¯>â¯0.05). However, the standard deviation of piglet BW (SDBW) was lower in ALTâ¯+â¯hCG72 (0.32â¯Â±â¯0.02â¯kg; pâ¯=â¯0.032), compared to ALTâ¯+â¯hCG96 (0.40â¯Â±â¯0.02â¯kg) and ALTâ¯+â¯no hCG (0.40â¯Â±â¯0.02â¯kg), except for the control (0.39â¯Â±â¯0.02â¯kg). In addition, the pre-weaning mortality rate (%PWM) due to underweight elimination at weaning (below 3.50â¯kg) was decreased in ALTâ¯+â¯hCG72 (8.33%) compared to the control (32.50%; pâ¯=â¯0.007) but similar to ALTâ¯+â¯hCG96 (10.71%) and ALTâ¯+â¯no hCG (24.05%). Therefore, ALTâ¯+â¯hCG72 treatment in sows could reduce piglet BW variation and the number of piglets eliminated at weaning.
