남은 음식물을 이용한 오리 사육 시험 = Feeding Effects of Food Waste in Growing Duck

국문 초록 (Abstract)

본 연구는 남은 음식물을 가축에게 이용하기 위하여 개발된 발효사료를 이용하여 오리를 사육했을 때 사양 효과를 검토하기 위하여 수행되었다. 육추가 끝난 16 일령 오리 80마리를 공시하여 배합사료의 50%를 남은 음식물 사료로 대체 급여하고 급여기간에 따라 대조구(0일), T_(1)(10일), T_(2)(15일), T_(3)(20일), T_(4)(25일)의 5개 처리에 배치하였다. 오리들은 57일령에 도살되었다.
시험완료시 체중은 대조구, T_(1), T_(2), T_(3) 및 T_(4)에서 각각 2376.Og, 2313.1g, 2308.1g, 2235.8g 및 2269.6g 으로 처리간에 차이가 없었다.
처리별 도체율은 각각 69.6%, 69.4%, 66.6%, 64.1% 및 70.8%로 T_(2)와 T_(3)에서 유의적으로 낮은 편이었다. (p＜0.05)
가식내장 중 근위의 무게는 각각 78.7g, 78.6g, 71.79g, 66.4g, 76.0g으로 T_(2)와 T_(3)에서 낮은 편이 었다. (p＜0.05)
본 시험결과 육용오리 사육시 남은 음식물 사료를 25일 간은 농후사료의 50%를 급여해도 좋을 것으로 나타났다.

This study was carried out to investigate the feeding effects of food waste in growing duck. The food waste was fermented before being used as a substitude of duck feed. The substitution level of fermented food waste during experment was 50% of commercial broiler feed. Eighty ducklings, 16days old age, were allocated to five treatments. The feeding periods of fermented food waste were control, 0 day ; T_(1), 10 days ; T_(2), 15 days ; T_(3), 20 days and T_(4), 25 days. Five ducks in each treatment were slaughtered at 57 days old.
The live weight of control, T_(1), T_(2), T_(3) and T_(4) at 57 days old were 2,336.0g, 2,313.1g, 2,308.1g, 2,235.8g and 2,269.6g, respectively. and there were no significant difference among treatments.
Dressing percentage of control, T_(1), T_(2), T_(3) and T_(4) were 69.6%, 69.4%, 66.6%, 64.1% and 70.8%, respectively, and those of T_(2) and T_(3) were significantly lower than other treatments(P<0.05)
The yields of gizzards of control, T_(1), T_(2), T_(3) and T_(4) were 78.7g, 78.6g,71.7g, 66.4g and 76.0g, respectively, and those of T_(2) and T_(3) were significantly lower than other treatment(P<0.05)
This results indicated that the food waste could be used as a substitude of growing duck feed for 25days.
