초록

본 연구는 버섯재배부산물, 재활용가금깔개, 미강 및 straw로 구성되는 BF 사일리지 급여가 육성 거세한우의 행동양상에 미치는 영향을 규명하기 위하여 실시하였다. 시험에 사용한 공시 한우는 11개월령 총 10두(평균 301.7 kg)를 2처리로 배치하였으며, 이 때 대조구(볏짚 자유채식)와 처리구(BF silage 자유채식)로 하여 48시간 행동관찰을 실시하였다. 대조구와 비교해서 BF 사일리지 급여구는 총 DM 섭취량과 NDF 섭취량이 각각 30% 및 36% 높았고, 채식시간, 반추시간 및 저작시간은 유의적인 차이가 없었다. 식괴수, 식괴당 반추시간에 있어서도 유의적 차이가 없었고, 식괴당 저작수와 FVI는 낮게 나타났다(p<0.05). 또한 대조구와 비교해서 BF 사일리지 급여구는 배뇨 회수가 높고(p<0.05), 음수 및 배분 회수에 있어서는 상호간에 차이가 없었고, 채식율, 반추효율 및 저작효율에 있어서는 더 높게 나타났다(p<0.05). 이상의 결과로 볼 때, BF 사일리지 급여는 볏짚과 비교 시 육성거세한우의 반추행동 상 큰 차이가 없다는 결과로 미루어 볼 때 차후 볏짚 대용으로 활용하여도 좋을 것으로 사료되었다. 즉 입자도가 큰 straw를 peNDF를 충족시키는 최소량을 혼합하여 부산물사료 사일리지를 제조, 급여하였을 때 육성거세한우의 반추행동은 볏짚 급여 시와 차이가 없었다.

This study was carried out to investigate the effects of a by-product feed-based silage (BF silage) feeding on behavior patterns of growing Hanwoo steers. A total of 10 Hanwoo steers (11 months old, 302kg of body weight) were assigned to 2 dietary treatments: the control (concentrate mix + free access to rice straw), and the treatment (concentrate mix + free access to BF silage). The behavior patterns were observed for 48 hours. The intakes of dry matter (DM) and neutral detergent fiber (NDF) of the treatment group were higher than those of the control group. Eating time, ruminating time and resting time were not different between the control and treatment. But, the intake time per kg DM was higher for the control than treatment. The number of bolus, total chewing frequency, number of ruminating per bolus and number of bolus per minute were not different between the control and treatment. But the chewing frequency per bolus was higher in the treatment than control (p<0.05), and feed value index was lower in treatment than control (p<0.05). Frequencies of drinking and defecating were not different between the two groups, but the frequency of urinating was higher for the treatment (p<0.05) than control. Eating rate, ruminating efficiency and chewing efficiency were much higher in the treatment group than control (p<0.05). These results indicate that the replacement of conventional rice straws with the BF silage (physically effective NDF, about 25%) did not affect the ruminating behaviors of Hanwoo steers significantly.
