Randomized feeding trial demonstrates increased egg production and weight in laying hens fed fermented wild-ginseng culture by-products, suggesting potential as a functional poultry feed additive.
본 시험은 발효 산삼 배양액 부산물 급여가 산란계의 계란 생산성, 계란 품질, 혈액 성상 및 난황내 진세노사이드 함량을 알아보고자 조사하였다. 시험 동물은 55주령 ISA Brown 216수를 공시하였고, 6주간 시험을 실시하였다. 시험사료는 기초사료를 대조구로 설정하였고, 처리구 1(WG1)은 기초사료의 lupin 2.5%을 발효 산삼 배양액 부산물로 배합하였고, 처리구 2(WG2)는 기초사료의 lupin 5.0%을 발효 산삼 배양액 부산물로 대체하여 배합하였다. 시험구는 각 처리구당 6반복, 반복당 12마리를 완전 임의 배치하였다. 산란율에서 전체기간동안 WG1과 WG2 처리구가 대조구에 비해 유의적으로 증가하였다(P<0.05). 난중은 WG2 처리구가 CON 처리구와 비교하여 유의적으로 높은 결과를 나타내었다(P<0.05). 난황색은 WG1과 CON처리구가 WG2 처리구와 비교하여 유의적으로 증가하였다(P<0.05). 난백고와 haugh unit는 WG1 처리구가 다른 처리구에 비해 유의적으로 결과를 나타내었다(P<0.05). 적혈구에서는 WG2 처리구가 CON 처리구에 비해 유의적으로 감소하였다(P<0.05). LDL 콜레스테롤은 CON 처리구가 WG2 처리구에 비해 유의적으로 감소하였다(P<0.05). 결론적으로 발효 산삼 배양액 부산물은 산란계의 산란율 및 난중을 개선하였다. The present study was conducted to investigate the effects of dietary supplementation of fermented wild-ginseng culture by-product on egg production, egg quality and blood characteristics in laying hens. A total of 216 ISA Brown laying hens, 55 wk of age, were used in the 6-wk feeding trial. Experimental diets were consisted of basal diet (CON), 2.5% fermented wild-ginseng culture by-product replaced lupin in basal diet (WG1) and 5.0% fermented wild-ginseng culture by-product replaced lupin in basal diet (WG2). Birds were randomly allotted to 18 replicate pens. There were 6 replicates per treatment, and 12 laying hens per replicate. Through the 6-wk feeding trial, egg production was significantly increased in WG1 and WG2 treatments compared to CON (P<0.05). Egg weight was significantly higher in WG2 than CON (P<0.05). WG1 resulted higher yolk color than CON (P<0.05). Albumen height and Haugh unit were significantly improve in WG1 compared to WG2 (P<0.05). Red blood cell was significantly lower in WG2 than CON (P<0.05). LDL-cholesterol was significantly decreased in CON compared to WG2 (P<0.05). In conclusion, fermented wild-ginseng culture by-product could improve egg production and egg weight in laying hens.
