Abstract

This study was carried out to investigate the effects of dietary Saccharomyces cerevisiae (wild yeast mutant) and Saccharomyces cerevisiae hFeHLC (ferritin containing yeast) and chelated Fe on growth performance and body composition of broiler chicks. A total of 252 (1-day old) 'Ross' broiler chicks were allotted to seven dietary treatments: I) control without iron supplementation, 2) 0.1% wild yeast mutant (YM03), 3) 1.0% wild yeast mutant, 4) 0.1% ferritin containing yeast (YF04), 5) 1.0% ferritin containing yeast, 6) 0.01% chelated Fe and 7) 0.1% chelated Fe. The highest weight gain obtained from broilers fed 0.01% chelated Fe was 2,121g, the lowest weight gain obtained from broilers fed control diet was 2.087g. The growth performance results were not significantly different in weight gain, feed intake and feed conversion ratio of broilers diets containing wild yeast, ferritin containing yeast and chelated Fe supplementation and control diets (P>0.05). The lowest iron content in meat was for control 30.51 mg/dL and the highest Fe content was for 0.1% ferritin containing yeast 41.58 mg/dL, but these were not significantly different (P>0.05).

본 연구는 유기태 철과 효모철의 첨가가 육계의 생산성 및 체조성에 미치는 영향에 대하여 연구하였다. 공시동물은 Ross broiler 252수로 7처리 6반복 반복당 6수씩 사양시험을 실시하였다. 처리구는 1) 대조구, 2) YM03 0.1%, 3) YM03 1.0%, 4) YF04 0.1%, 5) YF04 1.0%, 6) 유기태 Fe 0.01% 및 7) 유기태 Fe 0.1%로 총 7처리로 나누어 실시하였다. 증체량은 대조구가 2,087 g으로 낮게 나타났으며, 유기태 Fe 0.01% 첨가구가 2.121 g으로 나타나 대조구보다 높은 경향을 보였으나 통계적인 유의차는 보이지 않았다(P>0.05). 사료섭취량은 대조구는 3,797 g으로 낮게 나타났으며, YM03 1.0% 첨가구가 3,827 g으로 높게 나타나 대조구보다 높은 경향을 보였으나 통계적인 유의차는 보이지 않았다(P>0.05). 도체 Fe 함량은 대조구가 30.51 mg/dL 로 낮게 나타났으며, YF04 0.1 % 첨가구가 41.58 mg/dL 로 높게 나타나 대조구보다 높은 경향을 보였으나 통계적인 유의차는 보이지 않았다(P>0.05). 육계에서 사료내 유기태 철 또는 효모철의 첨가는 도체내 철의 함량을 강화시키고 철분이 강화된 축산물 생산이 가능할 것으로 사료되나 사업화하기 위해서는 추후에 더욱 체계적인 연구가 요구된다.
