초록

본 연구는 점등 조절 방법이 육계의 생산성과 육질에 미치는 영향을 구명하기 위해 수행되었다. 공시계는 1일령 초생추(Ross) 912수를 암수 구별하여 3처리 4반복 반복당 암컷 42수, 수컷 34수씩 공시하였다. 암수 모두 체중, 증체량, 사료섭취량 및 사료요구율은 유의차가 없었다(P>0.05). 가슴육의 가열감량과 보수력은 처리구간에 유의적인 차이가 없었다. 전단력은 점등 처리구가 자연일조에 비해 높게 나타났다(P<0.05). 계육의 일반성분(수분, 조단백질, 조지방, 조회분)은 암수 모두 처리구간 차이가 없었다. 결론적으로, 점등시간을 조절해 주는 것이 육계에 스트레스를 줄이면서 생산성을 높여줄 수 있다고 사료된다.

영어초록

The study was carried out to investigate the effect of lighting regimes on performance and meat quality of broiler. A total of 912 chicks was divided into 2 groups with male(3 replications/group, 34 heads/replication) and female(3 replications/group, 42 heads/replication). Treatments were control(C, natural lighting), T1 treatment(24L), and T2 treatment(1~2d, 24L; 2~4d, 23L+1D; 4~16d, 16L+8D; 16~21d, 18L+6D; 21~42d, 23L+1D) by lighting regimes. There was no significantly different on body weight, body weight gain, feed intake, and feed conversion ratio of male and female of broilers among treatments. There was no significantly different on cooking loss and water hold capacity of all broiler’s meats among treatments. Share force of lighting regimes was higher compared to control(P<0.05). There was no significantly different on common ingredients(moisture, crude protein, crude fat, and ash) of broiler's meat. Finally, lighting regimes may decrease the stress as well as improve the growth performance and meat quality of broilers.
