Abstract

This study investigated the effect of dried food-waste diets (FW) fermented by Aspergillus oryzae (AEW), on egg Production and egg qualify in laying hens. One hundred sixty eight laying hens, 50 week old, ISA-Brown wtrain were randomly distributed into 7 treatments with 3 relpicates of 8 birds per replicate and fed with standards laying hen diet replaced with FW and AFW at die=rent level Basal Diet, 25, 10, $75\%$, respectively. There was a significant decrease in feed intake for FW $50\%$ diet and egg Production was statistically lower in all W diet treatments(p<0.05). Water consumption was increased as the replacement increased. Egg weight, egg shell thickness and strength were similar among treatments. However, egg yolk color and Haugh unit showed distinct differences when W were added to their diets(p<0.05). No difference was observed in egg yolk cholesterol. It seems that FW diet could decrease the egg Production, but would be able to improve egg Quality. From this results, AO seemed applicable to laying hen diet as supplements.

본 시험은 시중에 유통되고 있는 일반 건조 잔반을 AO 배양물로서 산란계에 급여하여, 산란계의 생산성과 계란 품질에 미치는 영향을 구명하고자 실시하였다. 시험축은 평균 체중이 $1.5\pm0.5kg$인 50주령 산란계(ISA-Brown)를 공시하였고, 기초사료로 산란계 중기 사료를 급여하였으며, 시험사료는 대조구(Control), 잔반사료(FW)와 AO 배양물사료(AFW)를 각각 $25\%,\;50\%,\;75\%$씩 기초사료를 대체하여 총 7처리구, 3반복, 반복당 8수씩 168수를 공시하였다. 시험기간 중 사료섭취량에서 전처리구간 차이는 없었으나, FW구의 $50\%$ 처리구에서 대조구에 비해 유의적으로 감소했고, 산란률에 있어서는 대조구 $89.8\%$에 비해 AFW $25\%$ 처리구에서는 차이가 없었으나, 전 처리구에서 유의적으로 낮았다(p<0.05). 음수량은 잔반 사료의 대체 수준에 따라 증가하였다(p<0.05). 난중, 난각 두께 및 난각 강도는 전 처리구간 차이가 없었다. 호우유니트와 난황색에서는 남은 음식물 사료의 첨가에 따라 뚜렷한 차이를 보였으나(p<0.05) $50\%$ 이상의 첨가에서는 차이가 없었다. 남은 음식물사료의 첨가에 따른 난황내 콜레스테롤 함량에는 전 처리구간 차이가 없었다. 이러한 결과로부터, 잔반 사료는 산란율을 떨어뜨리지만, 난질 개선에 효과가 있고, 산란계 사료의 첨가제로서 AO 접종 잔반 사료의 사용이 가능할 수 있음을 시사한다.
