Abstract

The objective of the present study was to assess the effects of neem (Azadirachta indica) kernel powder supplementation on the digestibility of feed chemical components and the composition of caecal microbiota in guinea pig. One hundred and thirty guinea pigs were randomly assigned to four groups. For 27 days, the animals were fed once daily with either a standard control diet (complete concentrate) or a concentrated mixture with 2.5, 5 or 7.5% (w/w) neem kernel powder. The results showed a significant increase in feed intake and digestibility with the rate of kernel incorporation. In the caeca content, the log count of lactic acid bacteria and Clostridium butyricum increased quadratically (P < 0.001) with the supplementation level whereas Escherichia coli count decreased. The results suggest that neem kernel powder could be used as a phytogenic supplement for guinea pigs, enhancing both nutrient digestibility and gut microbiota quality.

豚鼠日粮中加入印楝仁：对消化率和盲肠健康的影响。

本试验旨在研究添加印楝仁粉对豚鼠饲料化学成分消化率和盲肠菌群组成的影响。130只豚鼠被随机分为四组。连续27 d，每天饲喂1次标准对照饲粮（完全浓缩）或添加2.5%、5%或7.5% （w/w）印楝仁粉的浓缩混合物。结果表明，采食量和消化率随籽粒掺入率显著提高。在盲肠含量中，乳酸菌和丁酸梭菌的对数计数呈二次增长(P
