Studies on "IKUTON" Fermented Sweet Potato Starch Pulp for Growing-Finnishing Swine Ration

IKUTON 발효(醱酵) 고구마 전분박(澱粉粕)의 농후사료대축수준(濃厚飼料代蓄水準) 調査하기 위하여 Large Yorkshire, Landrace, Duroc Jersey 삼품종(三品種) 교잡종(交雜種) 25두(頭)를 공시(供試)하여 농후사료(濃厚飼料)를 급여(給與)한 대조구(對照區)와 IKUTON 발효(醱酵) 고구마 전분박(澱粉粕) 10%, 20%, 30% 및 40%를 대치한 5개처리구(個處理區)를 완전임의배치(完全任意配置)하여 시험(試驗)한 결과(結果)를 요약(要約)하면 다음과 같다. 사료섭취량(飼料攝取量)은 40% 구(區)를 제외(除外)한 기타(其他)의 각처리구(各處理區)에서는 대조구(對照區)에 비(比)하여 유의적(有意的) (P<0.05)인 차이(差異)를 인정(認定)할 수 없었으며 40% 이상(以上)의 대체수준(代替水準)에서 사료섭취량(飼料攝取量)이 감소(減少)되고 있었다. 사료효율(飼料效率)은 20% 구(區); 3.43, 30% 구(區); 3.80, 10% 구(區) 3.97, 40% 구(區); 4.20, 0% 구(區0; 4.53의 순(順)으로 대조구(對照區)에 비(比)하여 높은 사료효율(飼料效率)을 나타내고 있었다. 증체량과 80kg 도달주수(到達週數)는 10% 구(區); 12주(週), 0%구(區); 13주(週), 20% 및 30%구(區)가 14주(週)였고 40%구(區)는 15주(週)까지도 80kg에 도달(到達)치 못하고 있었으며 대조구(對照區)에 비(比)하여 64%의 증체밖에 되지 않었다. 시험사료(試驗飼料)의 소화율(消化率)은 75.2~87.5%였으며 급수율(給水率)은 사료섭취(飼料攝取) 1kg당(當) $1.95-2.01{\ell}$로 되고 있어 사료급여회수(飼料給與回數)는 소화율(消化率)과 급수율(給水率)에 아무런 영향을 주지 않었다.

Study was conducted to estimate the nutritional effect of substitution levels of "IKUTON" (R) inocculate fermented sweet potato pulp for the growing-finnishing pig rations. Twenty five Large white X Landrace cross-breed (15 kg). mixed sex were used in group feeding at the substitution levels of 0, 10, 20, 30, and 40%. The results obtained were summarized as follow: Voluntary feed intake of experimental diets was lowest in 40%. No significant difference in voluntary feed intake was found in 10,20, and 30% levels except 40% P<0.05). The feed efficiency was highest in 20%; (3.43), 30%; (3.80), 10%; (3.97), control; (4.53), and 40%; (4.20) respectively. There was tendency toward increasing feed effioiency in 10,20,30% levels than control. However, the lowest feed efficiency was found in 40% level. The weeks required to gain 80 kg of live weight were 12 weeks for 10%, 13 weeks for control. 14 weeks for 20%, and 30%, but in 40% level of substitution, no 80kg live weight was found up to the end of experiment (15 weeks). Pigs in 40% level were gained live weight only 64% of control animals. The digestibility of experimental diets was 75.2-78.5%, and water intake per kg dry matter intake was $1.95-2.01{\ell}$. No significant effects of feed offer interval to the digestibility and water consumption.
