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.
本研究的目的是评估添加印楝（Azadirachta indica）籽粉对豚鼠饲料化学成分消化率和盲肠微生物群组成的影响。130只豚鼠被随机分为四组。在27天的时间里，每天给动物喂食一次标准对照饮食（全价浓缩饲料）或含有2.5%、5%或7.5%（w/w）印楝籽粉的浓缩混合物。结果表明，随着籽粉添加比例的增加，采食量和消化率显著提高。在盲肠内容物中，乳酸菌和丁酸梭菌的对数计数随着添加水平呈二次方增加（P < 0.001），而大肠杆菌计数减少。结果表明，印楝籽粉可作为豚鼠的植物源添加剂，提高营养物质消化率和肠道微生物群质量。
