초록
본 연구는 산란계에서 남은 음식물과 녹차 부산물이 산란계의 산란성적과 계란품질에 미치는 영향을 연구하였다. 공시동물은 50주령 Tetran Brown종 산란계 210수를 7처리 5반복 (반복당 6수)으로 임의 배치하였다. 시험설계는 대조구와 옥수수 곡류와 대두박을 대용한 건조된 남은음식물 10, 20, 30 및 40% 첨가구 (10% DLF, 20% DLF, 30% DLF 및 40% DLF)와 1.0%의 녹차 부산물 첨가구 (1.0% GTB)와 30% DLF와 1.0% GTB를 첨가한 혼합 첨가구를 두어 사양실험을 8주 동안 실시하였다. 산란율은 대조구에 비하여 10, 20 및 40% DLF 처리구에서 유의적으로 증가하였다 (P<0.05). 난중은 대조구에 비하여 10% DLF 처리구에서 유의적으로 감소하였다 (P<0.05). 사료 섭취량은 대조구보다 20% DLF 처리구와 30% DLF와 1.0% GTB의 혼합 첨가구에서 높게 나타났다 (P<0.05). 사료 요구율은 대조구에 비하여 10% DLF 처리구와 1.0% GTB 처리구에서 유의적으로 감소하였다 (P<0.05). 난황 콜레스테롤은 DLF 처리구와 대조구 사이에서 변화가 없었다 (P>0.05). 난황의 리놀렌산은 DLF 처리구와 1.0% GTB 첨가한 처리구에서 유의적으로 증가하였다.
This study was designed to determinate the effects of dried leftover food and green tea by-product on laying hens performance and egg quality in hens. A total of 210 "Tetran Brown" layers 50-weeks of age were assigned to 7 treatments in a completely randomized design. Each treatment had five replicates per treatment with six layers per replication. Seven dietary treatments were a control diet (formula diet) and dried leftover food (DLF) mixed in 10, 20, 30 and 40% to the control diet substituting the corn grain and soybean meal, control diet containing 1.0% GTB without DLF supplementation and control diet containing 30% DLF plus 1.0% GTB supplementation. The trial period was for 8 weeks. The egg production rate of layers was significantly increased in 10, 20 and 40% DLF treatments compared to that of the control treatment (P<0.05). The egg weight was significantly decreased in 10% DLF treatment compared to that of the control (P<0.05). The feed intake of layers was higher in 20% DLF and 30% DLF plus 1.0% GTB treatment than that of the control (P<0.05). The feed conversion ratio significantly decreased in 10% DLF and control plus 1.0% GTB treatments compared to that of the control (P<0.05). The egg yolk cholesterol not varied among the DLF and control treatments (P>0.05). However, the linolenic acid content of egg yolk was significantly increased in DLF and control treatments both containing 1.0% GTB supplementation.
