본 시험은 복합효소제 함유 식물성단백질공급원이 포유모돈의 생산성, 영양소 소화율 및 돈유성상에 미치는 효과를 알아보고자 실시하였다. 모돈은 건강상태 및 산차를 고려하여 3처리, 처리당 10두씩 30두를 공시하였다. 사료는 1차로 분만 일주일 전부터 급여하고 2차로 분만 후부터 21일령 이유시까지 급여하였다. 시험설계는 1)CON(basal diet), 2)CGLT(included corn gluten) 및 3) FSPM(included fermented soy protein containing multienzyme)로 하였으며, 분만후 자돈은 모돈에 복당 10마리씩 균일하게 배치하였다. 포유모돈의 영양소 소화율에서는 질소 소화율에서 FSPM 처리구가 CON 처리구와 비교하여 유의적으로 높았다(P<0.05). 포유모돈의 혈중 요소태질소 함량에서는 종료시에 FSPM 처리구가 CGLT 처리구보다 유의적으로 높았으며(P<0.05) 변화량에 있어서는 FSPM 처리구가 CON 및 CGLT 처리구보다 유의적으로 높았다(P<0.05). 포유모돈의 모유내 지방 함량에서는 종료시에 FSPM 처리구가 CON 처리구보다 유의적으로 높았으며(P<0.05), 모유내 단백질 함량에서는 개시시에 FSPM 처리구가 CGLT 처리구와 비교하여 유의적으로 높았다(P<0.05). 포유모돈의 직장온도 변화에 있어서는 세 처리 모두 유사한 변화를 보였다. 포유자돈의 성장률에서는 종료시체중, 증체량 및 일당증체량에서 FSPM 처리구가 CON 처리구와 비교하여 유의적으로 높았으며(P<0.05) CGLT 처리구는 CON 처리구보다 높았으며 FSPM 처리구보다 낮았다.포유자돈에서의 설사발생에 있어서는 0~5일째에 CGLT 처리구에서 한 마리가 발생하였다. 본 시험결과 사료내 0.25% 복합효소제 함유 식물성단백질공급원의 급여는 포유모돈의 질소 소화율과 혈중 요소태질소 함량, 모유내 단백질과 지방 함량을 향상시켰으며 포유자돈의 증체량 또한 향상시켰다.
Abstract
A total of thirty sows(Landrace×Yorkshire) were used to determine the effects of plant protein source containing multienzyme on performance, nutrients digestibility and milk characteristics. A feeding trial was conducted for 21 days from parturition to weaning. Experimental diets were supplied for 1 week before the parturition day and throughout the experimental period. Dietary treatments included: 1) Control(CON; basal diet), 2) CGLT(included corn gluten) and 3) FSPM(included fermented soy protein containing multienzyme). Through the entire experimental period, backfat loss and return-to-estrus intervals were not affected by the treatments(P>0.05). Nitrogen digestibility was increased significantly(P<0.05) in FSPM treatment compared to CON treatment. Blood urea nitrogen(BUN) concentration was increased significantly (P<0.05) in FSPM treatment compared to CON treatment. At the initial period, total protein content of milk was higher significantly(P<0.05) in FSPM treatment compared to CGLT treatment and at the final period, total fat content of milk was higher significantly(P<0.05) in FM treatment compared to CON treatment. Rectal temperature showed similar tendency of change among treatments. The final piglet body weight, weight gain and ADG were higher significantly in FSPM treatment compared to CON treatment. On diarrhea rate in piglet, just one piglet occurred in CGLT treatement. In conclusion, 2.5% dietary plant protein source containing multienzyme suppelmentation improved N digestibility, BUN concentration, fat and protein contents in milk and weight gain in piglet.
