초록

한우에서 분만 전, 분만 시 및 분만 후의 body condition score(BCS)와 이후의 번식능력과의 상관관계를 조사하였다. 2년 6개월에 걸쳐 33두의 한우에서 얻은 73회의 분만 산차(평균 $2.0\pm0.9$)에 대한 BCS 평가를 위하여 분만 2개월 및 1개월 전, 분만 시, 그리고 분만 후 7개월까지 매 1개월 간격으로 수행하였다. 분만 전 현저한 BCS의 감소에 대해서도 조사하였다. 분만 후 임신까지의 간격과 분만 1개월 전, 분만 시 그리고 분만 1개월 및 2개월 후 BCS 사이의 상관관계에 대하여 Pearson correlation analysis를 이용하여 분석하였다. 분만 후 임신까지의 간격과 분만 전 BCS의 감소에 대한 상관관계도 또한 분석하였다. 분만 후 임신까지의 간격은 분만 1개월 전 BCS (r=0.389, P=0.0007) 및 분만 전 BCS의 감소(r=0.488, P<0.0001)와는 정의 상관관계를 나타내었으나, 분만 시(r=-0.070, P=0.56)그리고 분만 1개월(r=0.107, P=0.37) 및 2개월 후(r=0.102, P=0.39)의 BCS와는 유의적인 상관관계를 나타내지 않았다. 분만 전 BCS의 감소는 분만 1개월 전 BCS와 정의 상관관계를 나타내었다(r=0.587, P<0.0001). 본 연구의 결과는 한우에서 분만 1개월 전 BCS는 이후의 번식능력을 예측하는데 유용한 기준으로 활용될 수 있으며, 또한 분만 전 비만 및 과도한 BCS의 감소의 예방은 번식능력을 증진시킬 수 있음을 보여 준다.

This study evaluated the correlation between the body condition score (BCS) during prepartum, calving and postpartum periods and the reproductive performance of Korean brown cattle. The BCSs of 33 cows who underwent 73 calvings over a two and a half period [the parities of the cows ranged from 1 to 4 ($mean{\pm}SD,\;2.0{\pm}0.9$)] were scored at months 2 and 1 prepartum, calving, and every month postpartum until month 7. A marked prepartum loss of BCS in the month preceding calving was noted. The correlations between the interval from calving to conception and the month 1 prepartum, calving and months 1 and 2 postpartum BCSs were analyzed by Pearson correlation analysis. The correlation between the interval from calving to conception and the prepartum body condition loss was also evaluated. The interval from calving to conception correlated positively with the month 1 prepartum BCS (r = 0.389, P = 0.0007) and the prepartum body condition loss (r = 0.488, P < 0.0001) but did not correlate significantly with the BCS at calving (r=-0.070, P=0.56) or months 1 (r=0.107, P=0.37) or 2 (r=0.102, P=0.39) postpartum. The prepartum body condition loss correlated positively with the month 1 prepartum BCS (r=0.587, P<0.0001). In conclusion, the month 1 prepartum BCS may be a good criterion for predicting subsequent reproductive performance. Moreover, the prevention of obesity and/or excessive prepartum body condition loss may result in higher fertility in Korean brown cattle.
