Improvement of Rumen Fermentation Efficiency Using Different Energy Sources: In Vitro Comparison between Buffalo and Cow

During haymaking and ensilage, a significant loss of sugars occurs. The addition total mixed ratio (TMR) with liquid feed might provide promptly utilisable energy recover the nutrients lost during conservation. Interesting results were already obtained by including in TMR dairy cow. However, possibility to also utilize them Italian Mediterranean buffalo is not yet supported data. This study aimed evaluate vitro fermentation characteristics kinetics different types feed, utilising bovine rumen liquor as inocula. supplemented 0.025 g four feeds was incubated control fluid using gas production technique. Considering inoculum, all experimental diets showed lower organic matter degradability higher volatile fatty acid than TMR, while liquor, differences observed between terms kinetics. tested can have patterns depending on their ingredients compositions. Supplementing standard diet seems source that improves fermentation. No negative effects at dosage utilised.
