Abstract:

The objective of this paper was to investigate the effects of three protein feeds (soybean meal,rapeseed meal and cottonseed meal) on quantities of ruminal proteobacteria (R.amylophilusB.fibrisolvens,P.ruminicoal and S.bovis) adhered to solid fractions in Sichuan Xuanhan Yellow cattle.Four rumen-cannulated Xuanhan Yellow cattle with similar healthy and weight were each fed four diets with different protein feeds over a period in a 4×4 Latin Square design,which were basal diet(CN),replaced 15% concentration of basal diet with soybean meal (SBM),rapeseed meal (RSM) and cottonseed meal (CSM),respectively.The PCR technique was used to analyze the change of the population of ruminal proteobacteria adhensive to solid fractions.The results showed that: 1)the quantities of R.amylophilusB.fibrisolvensP.ruminicoal and S.Bovis in group SBM reached the highest point at 9,9,5 and 5 h after morning feeding,the group RSM at 3,7,7 and 1 h,the group CSM at 9,9,7 and 1 h.2)the highest mean value was found in group SBM while the lowest in the group CSM on R.amylophilus(P<0.05) quantity; the highest mean value was recorded in group CSM while the lowest in SBM on the quantities of B.fibrisolvensP.ruminicoal and S.Bovis (P<0.05) quantities.In conclusion,different protein feeds significantly affected the quantities of ruminal proteobacteria,and cottonseed meal had a better promoting effect on ruminal proteobacteria adhensive to solid fractions.
