초록
본 실험은 포유기 사료 급여 기간의 변화가 포유 모돈의 생리적 변화와 번식 능력에 미치는 영향을조사하기 위해 수행되었다. 평균체중 256.15 ± 4.39kg의 F1 모돈(Yorkshire × Landrace) 30두를 공시하였으며, 완전임의배치법에 따라 3처리구에 배치하였다. 각 처리구는 1) L0-5: 임신기 110일령부터이유시까지 포유모돈 사료를 급여, 2) L0: 분만일부터 이유시까지 포유모돈 사료를 급여, 3) L0+5: 분만 5일 후부터 이유시까지 포유모돈 사료를 급여 하였다. 포유기에는 모돈들에게 사료를 무제한 급여하였으며, 실험결과 사료의 변화 시기는 모돈의 체중 및 등지방 두께에 유의적인 영향을 미치지 못하였다. 사료섭취량에 있어서 분만일부터 이유시까지 포유돈 사료를 섭취한 모돈이 수치적으로 가장 높았지만 처리구간 유의적인 차이는 나타나지 않았다. 산자수, 자돈의 체중 및 유성분에 있어서도 처리구간차이는 발견되지 않았다. 결론적으로 분만 5일전부터 5일후 사이에 포유돈 사료로 교체하는 것은 모돈의 번식능력 및 포유능력에는 긍정적인 영향을 미치지 않는 것으로 판단된다.
Abstract
This experiment was conducted to investigate the effects of different feeding period duringlactation on physiological response and reproductive performance of lactating sows. A total of30 F1 sows(Yorkshire×Landrace) with initial BW of 256.15 ± 4.39 kg were allocated to 1 of 3treatments according to feeding period using completely randomized design(CRD) in gestation of110 day. The treatments were 1) L0-5: sows fed lactating diets from 110day of gestation toweaning 2) L0: sows fed lactating diets from farrowing to weaning 3) L0+5: sows fed gestatingdiets 5 days after farrowing. Sows were provided ad libitum during the lactation period. Duringthe lactation period, body weight and backfat thickness were not affected by treatments(P>0.05). Voluntary feed intake of sows also did not significantly differ(P>0.05), but sows fed lactatingdiets from farrowing to weaning showed numerically lower than other treatments. There were nosignificant differences between treatments on litter size, litter and piglet weight as well as milkcomposition(P>0.05). The data of this experiment concluded that different feed period fromgestation to lactation 5 days before and after farrowing did not show any positive effect onsows reproductive performance and milk composition.
