試驗(yàn)研究了日糧中單獨(dú)或復(fù)合添加魔芋粉、布拉迪?對母豬圍產(chǎn)期便秘、初乳和奶水的質(zhì)量、泌乳期采食量以及仔豬生產(chǎn)性能的影響。144頭經(jīng)產(chǎn)母豬隨機(jī)分成4個處理：對照日糧組；日糧添加2.2%的魔芋粉組；日糧添加0.01%布拉迪?組；日糧添加1.2%魔芋粉和0.01%布拉迪組。妊娠期限飼，泌乳期自由采食。試驗(yàn)持續(xù)兩個繁殖周期。然而，在第一個繁殖周期結(jié)束時(shí)，一些仔豬被感染急性腹瀉，分析其余不被感染的仔豬沒有表現(xiàn)出組間差異。第二個繁殖周期的試驗(yàn)結(jié)果顯示四組間母豬體重、背膘厚、斷奶-發(fā)情間隔、糞便水份含量、初乳和奶水的組成無顯著差異。然而，與對照組相比，飼喂魔芋粉或（和）布拉迪?的三組在妊娠113天、產(chǎn)后4天和產(chǎn)后5天糞便評分更高。飼喂布拉迪?組和同時(shí)飼喂魔芋粉和布拉迪?組母豬糞便中梭菌和大腸桿菌數(shù)量顯著降低（P＜0.01），飼喂魔芋粉組母豬糞便中乳桿菌和梭菌數(shù)量顯著降低（P＜0.01）；飼喂魔芋粉或（和）布拉迪?的三組母豬泌乳期采食量顯著提高（P＜0.05），仔豬有更高的斷奶體重（P＜0.01）。

This study investigated the effects of supplementation of konjac flour (KF) and Saccha-romyces boulardii (SB) either alone or in combination to sow gestation diets over two successive reproductive cycles on constipation in peripartal period, quality of colostrum and milk, lactation feed intake of sows and piglet performance in the second reproduc-tive cycle. Multiparous large white sows (n = 144) were assigned randomly to one of four experimental treatments: the control diet; 2.2% KF diet; 0.01% SB diet; or 1.2% KF plus 0.01% SB diet. Sows from all four groups were restrict-fed with their respective diets during gestation and offered feed ad libitum during lactation. The sows remained on the dietary treatments for two reproductive cycles. However, at the end of the first reproductive cycle, some piglets in the experiment were affected by acute diarrhea and analysis of partial results of those which were not infected showed no treatment effects. The results for the second reproductive cycle showed that dietary treatments had no effect on body weight, backfat thickness, weaning-to-estrus interval, fecal moisture content or the composition of colostrum or milk. However, sows fed the three supplemented diets had higher fecal scores on day 113 of gestation (P < 0.05), days 4 (P < 0.01) and 5 (P < 0.05) of lactation than their control counterparts. Supplementation of the diets with SB and KF plus SB also reduced fecal counts for Clostridium and Escherichia coli (P < 0.01) while supplementation of the diet with KF increased fecal Lactobacillus counts and reduced Clostridium counts (P < 0.01). Sows fed the three supplemented diets also ate more feed during lactation (P < 0.05) and weaned significantly heavier pigs (P < 0.01) than those fed the control diet.
