摘要
通过给仔猪喂食微生态制剂,研究微生态制剂对仔猪生长性能、粪便pH值及肠道定植情况和肠道菌群的影响。结果表明,饲喂微生态制剂8周后,益生菌可以有效地定植在仔猪肠道内,并能够增加断奶仔猪的日增质量,降低料质量比和腹泻率。并且对仔猪生长性能的影响有时间效应,在断奶初期效果最佳;可以保持仔猪消化道的偏酸性环境,有利于益生菌的生长;还可以增加肠道中有益菌的数量,抑制有害菌的生长。
This experiment was conducted to study the effects of probiotics on growth,pH value of feces,colonization of certain strain and bacterial communities of intestine in weanling pigs. The results showed that,benefit bacterial can be colonized successfully in intestine after probiotie application for eight weeks,the daily gain was significantly increased （P〈O.05） whereas both feed gain ratio and diarrhea rate of weanling pigs were decreased significantly （P〈0.05）. Besides,growth response of piglets to probiotie displayed a time dependent pattern. It was most efficiency at early stages after weaned when acid environment can be maintain that would be benefit for piglets growth. Moreover,tile number of beneficial bacterial was increased but the number of harmful bacterial were decreased in the piglets intestine after probiotic application.
