남은음식물 사료와 생균제 첨가에 따른 육계의 성장 및 체조성에 미치는 영향

Effect of Food Waste Feed and Probiotics on Growth perfermance and Body Composition in Broiler

본 실험은 육계에서 남은 음식물 사료자원 개발의 일환으로 실시하였으며, 생산성을 좀더 큰 효과를 기대하기위해 남은 음식물에 생균제를 수준별로 첨가하여 급여할 경우 육계의 성장 및 체조성에 미치는 영향을 평가하기위하여 실시하였으며, 육계사료에 남은음식물 사료 15%에 첨가한 생균제 0.5%, 1.0%, 1.5% 첨가구 및 항생제 0.1%첨가구로 총 6처리 4반복 반복당 7수씩 총 196수로 6주간 사양시험을 하였으며 그 결과는 다음과 같다. 체조성은 대조구가 17.52% 비해 생균제 1.0%첨가구가 15.57%로 단백질 함량 수치가 낮게 나타났다 (P>0.05). 조지방은 대조구가 3.30%인 반면 남은음식물 사료는 6.44%로 음식물에 지방 함량이 높게 나타났다 (P<0.05). 조회분은 대조구가 1.41%로서 항생제 1.53% 비해 첨가구들이 1.75%. 1.72% 및 2.13%로 높았다 (P<0.05). Stearic acid, linoleic acid 지방산이 대조구에 비해 첨가구들이 낮은 수치를 나타냈으며 mystic asid, palmitoleic acid 지방산은 대조구 비해 첨가구들이 높은 수치를 나타냈다 (P<0.05). 복강내 지방 함량은 장기무게 비율은 대조구 1.05 g로 남은음식물 생균제 1.5%첨가구가 2.30 g로 두배의 차이로 높은 비율을 나타났다 (P<0.05).

The objective of this study was to determinate the effect of food waste with probiotic supplemented diets on growth performance and body composition in broiler chicks. One hundred ninety six (Ross 1 day old) broiler chicks were randomly allotted to seven treatments and raised in barely cages. As the results of the experiment the body weight gain was increased significantly in groups fed control+antibiotics supplemented diets (P<0.05), but there were no significant difference in weight gain of the chicks fed diets containing food waste with probiotic and antibiotic supplementations (P>0.05). The feed intake was increased significantly in group fed a diet containing food waste 1.5% with 0.5% probiotic supplementation but it was no significantly different for rest experimental groups (P>0.05). The feed efficiency was reduced significantly in broilers fed food waste with probiotic diets compared to groups fed control and antibiotic supplemented diets (P>0.05). The large intestine weight was increased significantly in broilers fed antibiotic supplemented diet compared to control (P<0.05). The abdominal fat was increased in groups fed diet containing food waste supplementation (P<0.05). The rest of vital organs weights was not affected by additon of food waste and probiotic supplementation in broiler diet (P>0.05).
