中文摘要 | 試驗利用二品種雜交母豬16 頭於懷孕期第80 日至分娩,逢機分配於每日飼料餵 量分別為 2.5、3.0 和 3.7kg 三個處理組中,以探討經產母豬於懷孕後期增加飼料量對出 生仔豬和泌乳母豬性能之影響。懷孕期飼料之消化能為 3.36Mcal/kg、蛋白質為 13% 和離 胺酸 0.60%,泌乳期飼料為蛋白質 15%、離胺酸 0.95% 和消化能 3.35Mcal/kg。母豬在配 種後每日餵給 1.8kg 懷孕期飼料,直到懷孕 80 日時改以上述三種飼料餵量, 飼料每日餵 飼二次, 28 日泌乳期飼料改為任食。試驗結果顯示,懷孕母豬在配種 80 日後每日餵飼 2.5kg 飼料,其出生仔豬之體重低於 1.0kg 以下者達 34.63%,顯著地 (P<0.05) 高於其他 兩組。各處理組母豬之出生仔豬總頭數、存活頭數及存活仔豬體重在統計上無顯著差異,但 以 2.5kg 飼料組之出生仔豬體重較另兩組為輕的趨勢,依次分別為 1.20、1.35 和 1.37kg 。 存活率分別為 79.95、92.85 和 87.90%,以 2.5 kg 飼料組之仔豬存活率為低。泌乳期 間母豬哺育仔豬數、每日飼料採食量、母豬體重和背脂變化、哺乳仔豬存活率、窩增重和離 乳時仔豬體重, 各處理間的差異均不顯著。 故高產次母豬在懷孕 80 日以後, 每日餵飼 2.5kg 飼料稍嫌不足,若能提高到 3.0kg 可減少出生體重低於 1kg 仔豬比例,並改善出生 仔豬存活率 12.90 個百分點。飼料量增加到 3.7 kg 並無進一步的改善效果。 |
英文摘要 | A total of 16 crossbred multiparous sows (average 6.6 parities) was randomly allocated to three levels of daily feed intake 2.5,3.0,and 3.7 kg on day 80 of gestation to study the effect of additional feed during late gestation on the performance of piglets and lactating sows. The gestation diet was formulated to contain 3.36 Mcal/kg of digestible energy, 13% crude protein, and 0.6% lysine and the lactation diet contain 3.35 Mcal/kg of digestible energy, 15% crude protein, and 0.95% lysine. Each sow was fed with 1.8 kg diet daily after breeding until day 80 of gestation where by diets was changed to three levels of feed intake. Sows were fed on ad libitum basis through the 28-day lactation period. The results indicated that the percentage of piglet birth weight which was less than 1.0 kg was higher (34.63%) for those from sows receiving 2.5 kg/day of feed, and significantly higher than the 3.0 and 3.7 kg/day group during late gestation period. There were no significant differences in litter performance on litter size, number of live piglets, or weight of live piglets at birth. However, the piglet birth weight from sows receiving 2.5 kg/day of feed was lighter than from the other treatments (1.20,1.35, and 1.37 kg, respectively). Piglet survival rate at birth was 79.95, 92.85, and 87.90%, respectively, and there was a trend that the lowest piglet survival rate was from sows receiving 2.5 kg/day of feed. There were no significant differences in daily feed intake, piglets nursed, change of body weight and backfat thickness of sows during lactation, or survival rate on nurse and litter weight gain of weaned piglets. In conclusion, these results indicated that daily feed intake of sows receiving 2.5 kg during late gestation period was slightly low; when the level of feed was increased to 3.0 kg for sows it decreased the percentage of piglets at birth which body weight was less than 1.0 kg. Moreover, the survival rate of piglets at birth increased by 12.90 percentage units. Performance of lactating sows was not better with the level of feed intake at 3.7 kg. |
