Rumen ecology plays an important role in the fermentation process and in providing end-products for ruminants. These studies were carried out to investigate variations in rumen factors namely pH, $NH_3-N$ and microorganisms in cattle and swamp buffaloes. Furthermore, studies on diurnal patterns of rumen fermentation and the effect of rumen digesta transfer from buffalo to cattle was conducted. Based on these studies, diurnal fermentation patterns in both cattle and buffaloes were revealed. It was found that rumen NH3-N was a major limiting factor. Rumen digesta transfer from buffalo to cattle from buffalo to cattle was achievable. Monitoring rumen digesta for 14d after transfer showed an improved rumen ecology in cattle as compared to that of original cattle and buffalo. It is probable that buffalo rumen digesta could be transferred. However, further research should be undertaken in these regards in order to improve rumen ecology especially for buffalo-based rumen.

제안 방법
The objectives of these experiments were to identify the rumen fermentation pattern in buffalo and cattle fed on untreated and urea-treated rice straw and to investigate the feasibility and practicality of rumen digesta transfer.
데이터처리
Digestibilities of nutrients were calculated. All data were subjected to ANOVA and treatment means comparisons were conducted by Duncan’s New Multiple Range Test using Proc GLM (SAS, 1985).
Sampling of rumen fluid were taken at 0, 4 h post feeding, before transfer, and 7 and 14 days after rumen digesta transfer to be measured for rumen pH, NH3-N, VFAs and total viable counts of cellulolytic, proteolytic and amylolytic bacteria using standard methods as indicated above. All data were subjected to ANOVA and treatment means were compared sing Duncan’s New Multiple Range Test (Proc. GLM, SAS, 1985).
성능/효과
Apparent digestibilities are shown in Table 2. As presented, urea-treated rice straw (UTRS) digestibilities were the highest of the three feed treatments (p<0.05) and digestibilities of nutrients particularly those of organic matter and crude protein were higher in buffalo than cattle. Several factors have been suggested to attribute to these values.
