中文摘要 | 5個試驗探討有機銅來源與添加量對仔豬生長性能與發病率之影響。試驗一,72頭28日齡離乳仔豬(7.4kg)供餵加藥仔豬基礎料添加多醣銅 0、90、135與180ppm等4 種試驗料。試驗二,72頭28日齡離乳仔豬(6.3kg)供餵未加藥仔豬基礎料添加多醣銅、蛋白銅與胺基銅各100ppm等4種試驗料。試驗三,48頭28日齡離乳仔豬(7.2kg)供餵加藥仔豬基礎料添加硫酸銅250ppm或多醣銅、蛋白銅與胺基銅各100ppm等4種試驗料。試驗四,12頭56日齡仔豬(12.5kg)進行豬霍亂沙氏桿菌攻擊試驗,處理與飼料如試驗二。試驗五,24 頭仔豬(14.5kg)進行代謝試驗,供餵4種飼料如試驗二。由試驗一得知,多醣銅有促進生長的效果,建議用量為100 ppm。試驗二3種有機銅來源和對照組相比較,離乳後14-28天添加多醣銅與蛋白銅有較好的增重(p<0.05),全期(離乳後0-28天)的隻日增重、飼料攝食量與飼料效率有改善的趨勢(p=0.06),至於3種有機銅來源的飼養效果相近似。試驗三添加有機銅100ppm的發病率和添加250ppm硫酸銅的結果相似,並有減少銅污染的效果。試驗四添加有機銅不能減少豬霍亂沙氏桿菌症之發生,但有減少發病後仔豬失重之趨勢(p=0.09)。3 種有機銅肝銅量之測定平均值介於46-53ppm/DM 之間,顯著地高於對照組(p<0.05)。試驗五添加有機銅有改進蓄積氮╱消化氮之效果(p<0.05)。蓄積銅╱攝食銅與蓄積銅╱消化銅方面,3種有機銅組之測定平均值依序為16.87與85.09%,依序比對照組提高53.22與37.11%。 |
英文摘要 | Five trials were conducted to determine the effects of copper sources and level on performance and incidence ofdiarrhea of weaning pigs. In Exp.1, 72, 28 d-old, averaging 7.4 kg were fed medicated basal diet containing Cupolysaccharide complex (CPC) 0, 90, 135, or 180 ppm. In Exp. 2,72,28 d-old, averaging 6.3 kg were fed unmedicated basal diets containing CPC, Cu proteinate (CP), or Cu amino acid complex (CAAC) 100ppm. In Exp. 3, 48, 28 d-old, averaging 7.2 kg were fed medicated basal diet containing copper sulfate 250ppm, and CPC, CP, and CAAC 100ppm. In Exp. 4,12,56 d-old, averaging 12.5kg were fed diets the same as Exp.2 to conduct the observation of salmonellacholeraesuis challenge. In Exp. 5,24 starter pigs (14.5kg) were fed diets the same as Exp.2 to conduct the nitrogen balance determination. In Exp. 1, addition of CPC improved growth in weaning pigs. The optimum level of Cu from CPC was 100ppm. In Exp.2, pigs fed the three organic copper had better ADG(p<0.05) than did control pigs from d 14 to 28 postweaning. Overall, the rate and efficiency of gain also had a better tendency for weaning pigs. Sources of Cu from three organic coppers did not differ. In Exp.3, adding 100 ppm Cu from the three organic coppers was not worse than in weaning pigs given 250 ppm Cu from copper sulfate in the incidence of diarrhea and in helping to decrease the occurrence of Cu contamination. In Exp.4, adding organic copper did not prevent the incidence of salmonella choleraesuis, but there was a tendency toward improving the incidence of weight loss of weaning pigs (p=0.09). Regardless of the Cu source, avg liver Cu level was 46-53 ppm/DM in pigs fed three organic coppers, all significantly higher than for control pigs (p< 0.05). In Exp.5, adding organic coppers improved N retention/Nitrogen digestion (p< 0.05). The average three organic source copper Cu retention/Cu intake and Cu retention/Cu digestion were 16.87 and 85.09%, respectively; thus, Cu retention was increased 16.87 and 85.1%, respectively, compared with control pigs. |
