中文摘要 | 利用53頭平均約三產次的約克夏姆母豬探討泌乳飼料中不同能量來源對涼熱兩季飼養母豬和哺乳仔豬性能之影響。主要不同能量來源為15%麩皮和6%大豆油替代玉米-大豆粕飼料中之玉米並維持相同的離胺酸和澱粉量。泌乳期四週期間,母豬任食麩皮飼料(脂肪和纖維量:2.26和4.32%、消化能3.23 Mcal/kg),玉米飼料(脂肪和纖維量:2.67和3.06%,消化能3.40 Mcal/kg)和脂肪飼料(脂肪和纖維量:8.17和2.98%,消化能3.63 Mcal/kg)。 試驗結果顯示,母豬供應不同能量來源飼料在涼季(平均溫度19.52℃)並未顯著影響其飼料採食量、體重變化和離乳後再發情間距。但在熱季(平均溫度26.96℃)母豬採食脂肪飼料減少其體重損失和離乳後再發情天數。飼料纖維和脂肪量並不影響仔豬窩增重。熱季母豬給予高脂肪量飼料提高仔豬每日增重。 |
英文摘要 | A total of 53 sows (average 3.0 parities) were used to study the effect of different energy sources in the lactation diet on the performance of sows and suckling piglets during warm and cool seasons. The major differences in energy sources were 15% wheat bran and 6% soya oil instead of corn concentrations to maintain the same lysine and starch levels. The sows received the wheat bran diet (fat and fiber content: 2.26 and 4.32%, DE 3.23 Mcal/kg), the corn diet (fat and fiber content: 2.67 and 3.06%, DE 3.40 Mcal/kg) and the fat diet (fat and fiber content: 8.17 and 2.98%, DE 3.63 Mcal/kg) ad libitum during 4 weeks of lactation. The feed intake, live weight, and days from weaning to estrus were not significantly affected by the different energy sources during cool season (average temperature 19.52°C), but during warm season (average temperature 26.96°C). Sows consuming the fat diet reduced (P<0.05) weight lost and days from weaning to estrus. The weight gain of litter was not influenced significantly by the dietary fiber and fat levels, although piglet growth was higher from sows given the high dietary fat level during warm season. |
