title: Effect of dried rumen digesta pellet levels on feed use, rumen ecology, and blood metabolite in swamp buffalo.
abstract: The aim of this experiment was to determine the effect of dried rumen digesta pellet levels on feed intake, digestibility, rumen ecology, and blood metabolites in swamp buffalo. Four 2-year-old male swamp buffalo with an initial body weight (BW) of 150 ± 10.0 kg were randomly assigned according to a 4 × 4 Latin square design to receive four levels of dried rumen digesta pellets (DRDPs). The dietary treatments were supplementation of DRDP at 0, 50, 100, and 150 g dry matter/day, respectively. Total feed intake was significantly different among treatments (p < 0.05) and was highest in the 150 g/day DRDP supplement (2.68 kg/day). Intakes of neutral detergent fiber (NDF) and acid detergent fiber did not affect DRDP levels, while intakes of organic matter and crude protein (CP) were altered significantly when 150 g of DRDP was used (p < 0.05). Buffalo fed with DRDP at 150 g/day had the highest CP and NDF digestibility (p < 0.05). DRDP supplementation did not affect rumen pH, and temperature and the concentration of ruminal ammonia-nitrogen and blood urea nitrogen were not altered among the treatments. The mean value of fungal zoospores in the buffalo was significantly different among treatments and was highest in supplementation with DRDP at 150 g. The mean value of propionic acid was significantly different at various levels of DRDP; it was highest in the group fed with 150 g DRDP (p < 0.05). Thus, supplementation of DRDP at 150 g improved feed use and increased fungal zoospore population. In addition, DRDP feeding is recommended, since it has positive economic impacts and helps control environmental pollution.
