不同蛋白质饲料对宣汉黄牛瘤胃固相黏附纤维降解微生物数量的影响
Different Protein Feeds Affect Populations of Cellulosis Microbes Adherent to Solid Fractions in Rumen of Xuanhan Yellow Cattle
摘要
Abstract
The objective of this paper was to investigate the effects of three protein feeds ( soybean meal, rape-seed meal and cottonseed meal) on the populations of cellulosis microbes adherent to solid fractions in rumen of Xuanhan yellow cattle. Four healthy rumen-cannulated Xuanhan yellow cattle with similar body weight were used in a 4×4 Latin Square design. There were 4 periods with 10 days in each period. Cattle in basal group were fed a basal diet, and those in experimental groups were fed experimental diets, in which concentrate in basal diet were replaced by soybean meal ( SBM group ) , rapeseed meal ( RSM group ) and cottonseed meal ( CSM group) at 15% of basal diet, respectively. The fluorescent quantitation PCR technique was introduced to analyze the change of the populations of fungi, protozoa, R. albus, R. flavefaciens, and F. succinogenes ad-herent to solid fractions in rumen after 1, 3, 5, 7 and 9 hours of feeding. The results showed as follows: 1) with the increasing of time after feeding, there was no the same trend in different groups on the population of cellulosis microbes adherent to solid fractions in rumen. The populations of cellulosis microbes in SBM group reached the highest concentrated at 5 and 7 hours after feeding, and those in CSM group almost did at 7 hours after feeding. 2) Compared among means at different time after feeding of different groups, the population of fungi in CSM group was significantly higher than that in RSM and SBM groups ( P<0.05) , and the population of protozoa, R. flavefaciens and F. succinogenes in RSM group were significantly higher than those in SBM and CSM groups ( P<0.05 or P<0.01) . In conclusion, different protein feeds significantly affect the cellulosis microbes adherent to solid fractions in rumen, and rapeseed meal has better promoting effects on cellulosis mi-crobes adherent to solid fractions in rumen of Xuanhan yellow cattle.关键词
