Abstract

The study was conducted to evaluate the effects of dietary organic acid mixture(lactic acid 12%, formic acid 9%, citric acid 5%, butyric acid 5% and phosphoric acid 6%) on growth performance, organ weight, blood immunological parameter and intestinal villi morphology in broilers. Dietary treatments included 1) CON (basal diet), 2) OA1 (basal diet + 0.1% organic acid mixture) and 3) OA2 (basal diet + 0.2% organic acid mixture). Four hundred eighty hatched Arbor Acre broiler chickens were housed in 24 pens of 20 birds each. Eight replicate pens were allotted into each treatment by completely randomized design. Daily weight gain, feed intake and feed/gain were not significantly different among the treatments. In organ weight, that of gizzard was significantly heavier in OA2 than CON (Linear effect = 0.034). However, those of spleen and intestine were not significantly different among the treatments. Blood immunological parameters such as RBC, WBC and lymphocyte were not significantly difference. In intestinal villi morphology, villi length was increased in OA1 compared to CON (Quadratic effect = 0.050). In conclusion, 0.2% organic acid mixture was effective to improve gizzard weight of broilers.

본 연구는 유기산 복합제(lactic acid 12%, formic acid 9%, citric acid 5%, butyric acid 5% and phosphoric acid 6%) 급여가 육계의 생산성, 장기무게, 장내 융모 형태 및 혈액내 면역적 특성에 미치는 영향을 알아보기 위해 시험을 실시하였다. 사양 시험은 2일령 Arbor Acre Broiler(male) 480수를 공시하였으며, 5주간 사양 시험을 실시하였다. 시험 설계는 1) CON(기초 사료), 2) OA1(기초 사료 + 유기산 복합제 0.1%) 및 3) OA2(기초 사료 + 유기산 복합제 0.2%)로 3개 처리를 하여 처리당 8반복, 반복당 20수씩 완전 임의 배치하였다. 전체 시험 기간동안 생산성은 처리구간 유의적인 차이가 없었다. 장기 무게에서는 근위 무게가 CON 처리구와 비교하여 OA2 처리구가 유의적으로 높게 나타내었다(Linear effect = 0.034). 하지만, 비장과 소장 무게에서는 처리구간 차이를 나타내지 않았다. 혈액내 면역적 성상에서는 처리구간 차이를 나타내지 않았다. 장의 융모에서는 CON 처리구와 비교하여 OA1 처리구가 유의적으로 높게 나타났다(Quadratic effect = 0.050). 결론적으로, 본 시험의 결과 육계에 0.2% 유기산 복합제를 급여시 근위의 중량을 증가시키고, 0.1% 급여 시는 소장 융모의 길이를 증가시키는 효과가 있었다.
