초록
본 연구의 목적은 고령토(Kaolin)의 수준별 급여(실험 1)와 주령이 서로 다른 산란계의 수준별 급여(실험 2)가 산란계의 성적, 난품질 및 난각품질에 미치는 영향을 조사하기 위해 실시하였다. 실험 1에서는 58주령 산란계 총 64수를 이용하여 고령토 0.0, 0.2, 0.4 및 0.6% 급여구로 구분하였다. 실험 2에서는 두 가지 주령(30과 58주령)의 산란계와 세 가지 수준(0.0, 0.2 및 0.4%)의 고령토를 2×3 요인분석법으로 설계하였다. 두 실험의 결과, 고령토를 첨가하여 산란계에 급여하면 사료섭취량이 적어지고 사료요구율과 산란율이 개선되는 것을 관찰할 수 있었다. 그러나 난품질과 난각의 품질에는 고령토 첨가에 의한 효과가 나타나지 않았다. 이상의 결과에서 목질고령토의 첨가는 사료효율을 개선하고 산란율을 높여주는 기능이 있는 것으로 판단되며, 첨가수준은 30주령에서는 0.2%, 58주령에서는 0.2, 0,4%가 적정하다고 판단된다.
Abstract
Two experiments were conducted to determine the effects of supplementing different levels of kaolin(Exp. 1) and effects of age of layers and levels of kaolin(Exp. 2) on the performance, egg and shell quality parameters of laying hens. In Exp.1, 64 laying hens of 58 wks age were randomly allotted to 4 treatments of 16 hens in each. Dietary treatments were basal diet supplemented with 0.0, 0.2, 0.4 and 0.6% kaolin. In Exp. 2 96 laying hens were divided into 6 groups of 16 hens each in a 2 x 3 factorial arrangement(two different ages, 30 and 58 wk and three levels of kaolin, 0.0, 0.2 and 0.4%). In both the experiment there were linear decreases in feed intake(P<0.001), improvement in FCR(P<0.05), and egg production(P<0.05), with increasing dietary kolin level. Supplementation of kaolin had no effect on the egg and shell quality parameters in both experiments. Thus, it is concluded that kaolin may improve performance, and 0.2% level showed the best laying performance.
