摘要
对不同日粮条件下鹅盲肠内微生物发酵情况及切除盲肠对纤维类成分消化的影响进行了研究。结果表明,日粮中添加青绿饲料后,鹅盲肠内食糜量、总脱氢酶活力和挥发性脂肪酸(VFA)含量均不同程度升高,放牧时升高更显著。消化实验证明,鹅对半纤维素消化率高达41.54%,并能消化部分纤维素;切除盲肠后,纤维类成分消化率呈下降趋势,粪便水分含量升高.
Microbial fermentation in goose ceca fed different diets and effects of cecectomy on fibrecomponents digestion were studied.The results showed that adding fresh forage in diet increased chymeamount,total dehydrogenase activity and volatile fatty acid concentration,more significant incrementswere obtained under grazing.Experiment proved that the hemicellulose digestibility was 41.54%,butdigestibility of cellulose was low.After cecectomy water content in feces increased and fibre componentsdigestibility decreased.
