Four rumen fistulated swamp buffalo

Four rumen fistulated swamp buffalo bulls were randomly assigned to receive dietary treatments
according to a 4×4 Latin square design. The four dietary treatments were unsupplementation
(control), supplementation with coconut oil (CO) at 50 g/kg, supplementation with mangosteen
peel (MP) at 30 g/kg, and supplementation with CO at 50 g/kg and MP at 30 g/kg (COM), of total
dry matter intake. Animals received concentrate at 10 g/kg BW, together with a basal diet of ad
libitum rice straw. Feed intake, digestibility of dry matter, organic matter and crude protein were
not significantly affected; however, MP supplementation resulted in significantly lower overall
NDF and ADF digestibility when compared with COM supplementation. Ruminal pH and BUN
concentrations were not significantly different between treatments, while supplementation with
CO increased concentration of ruminal NH3–N. Total volatile fatty acid concentrations were
increased with MP supplementation. The proportion of ruminal acetic acid was decreased while
propionic acid was increased by either CO or COM supplementation. The ruminal protozoal
population was dramatically decreased with either CO or MP supplementation; whereas, COM
treatment had a lower fungal zoospores population when compared with the control group.
Supplementation with MP resulted in a lower population of cellulolytic bacteria than
supplementation with COM. In addition, CO supplementation resulted in a higher population of
proteolytic bacteria than the control or supplementation with COM. Nitrogen balance and
microbial protein synthesiswere not affected by CO or MP supplementation. In conclusion, CO or
MP supplementation could improve rumen fermentation by positively affecting the ruminal on
microbial population in swamp buffalo on rice straw diets.
