Abstract

This study was conducted to investigate the effects of dietary Animunin Powder$^{?}$ on the egg quality characteristics, blood components and nutrient digestibility in laying hens. A total of two hundred seventy laying hens were randomly allocated into three treaments with fifteen replications for eight weeks. Dietary treaments included 1) Control (CON), 2) Control + $0.1\%$ Animunin Powder$^{?}$ (AM1), 3) Control + $0.2\%$ Animunin Powder$^{?}$ (AM2). During the period of 0~4weeks, the birds fed the AM1 diet had an improved egg production compared to the birds fed the CON (P<0.05). During the period of 4~8weeks the birds fed AM1 diet showed a statistically improved egg production compared to the CON (P<0.05). However, no significant differences were founded in the egg weight. During the period of $4\~8$ weeks the hens fed the AM2 diet had improved egg yolk color compared to the hens fed CON and AM1 diets (P<0.05). In the Haugh unit for the period of $0~4$$weeks, the AM2 treatment showed significantly improved results compared to the CON (P<0.05). Average egg shell breaking showed no significant differences through the experiment period, but in the period of $4\~8$weeks the AM2 treatment tended to be improved compared to the CON and AM1 treatment (P<0.05). There was no significant differences in egg shell thickness. In the serum cholesterol, the AM1 and AM2 treatments were significantly lower than the CON (P<0.05). The concentration of RBC and WBC in the AM treatments tended to increase but there were no significant differences. For the differences of lymphocytes between the end and initiation of the experiment, the hens fed the AM1 treatment were significantly different compared to the hens fed the CON and AM2 treatment (P<0.05). During the period of the experiment, the hens fed the AM1 diet were tended to show higher DM digestibility than the hens fed the CON and AM2 diet, but it was not statistically different. In conclusion, dieatry fed of Animunin Powder$^{?}$ could improve egg production, egg yolk color, and haugh unit.

본 연구는 산란계에 Animunin Powder$^{(R)}$를 첨가 급여시 계란 품질, 혈액 성상 및 영양소 소화율에 미치는 영향을 알아보고자 실시하였다. 이를 위해 22주령 Hy-line Brown 270수를 공시하였고 사양시험은 10일간의 적응기간 후, 5주간 실시하였다. 시험처리구는 Animunin Powder$^{?}$의 첨가수준에 따라 1) Control(CON), 2) Control + $0.1\%$ Animunin Powder$^{(R)}$ (AM1), 3) Control + $0.2\%$ Animunin Powder$^{(R)}$ (AM2)로 3개 처리를 하여 처리당 15반복 반복당 6수씩 임의배치하였다. 산란률은 4주 동안의 기간에서 AM1 처리구가 대조구보다 통계적으로 유의하게 높은 산란률을 보였으며(P<0.05), 8주 동안의 기간에서도 AM1 처리구가 대조구보다 유의적으로 높은 산란률을 보였다(P<0.05). 난중에 있어서는 시험 기간동안 유의적인 차이를 발견할 수 없었다. 난황색은 8주에서 AM2 처리구가 대조구 및 AM1 처리구에 비해 유의하게 높았다(P<0.05). Haugh unit은 4주에서 AM 처리구가 대조구에 비해 유의하게 높은 수치를 보였다(P<0.05). 난각 강도는 처리구간 유의적인 차이를 발견하지 못하였으나, 8주에서 AM2 처리구가 대조구 및 AM1 처리구에 비해 높은 경향을 나타내었다. 난각 두께는 전 기간에 걸쳐 유의적인 차이를 보이지 않았다. 혈청내 콜레스테롤에서는 Animunin Powder$^{(R)}$ 첨가한 시험구에서 콜레스테롤 함량이 유의적으로 낮았다(P<0.05). RBC 및 WBC에서는 허브의 첨가 수준에 따라서 혈액내 RBC및 WBC의 함량이 증가하는 경향을 보였으나 유의적인 차이는 없었다. Lymphocyte는 개시시와 종료시의 변화에서 AM1 처리구가 대조구와 AM2 처리구에 비해 유의적으로 높았다(P<0.05). 4주 및 8주에서 AM1 처리구가 건물의 소화율에서 대조구 및 AM1 처리구에 비해 높은 결과를 나타내었지만 통계적으로 유의적인 차이를 발견하지 못하였다. 결론적으로 산란계에 Animunin Powder$^{(R)}$를 급여 시 생산성 향상에 도움을 주리라 사료된다.
