Energy and protein losses in rumen fermentation reduce the efficiency of nutrient utilization and cause environmental pollution.

Efficacy of essence oil supplementation to feeds on volatile fatty acid production

Poult Sci ; The objectives of this study were to compare the production of VFA of a culture of reactivated cellulolytic bacteria CBC with that of total ruminal bacteria TRB in cellulosic substrates, and to evaluate the relationship between VFA and in vitro degradation. Similar to Asadi et al. Less saliva leads to less buffer capacity to maintain pH within the optimal range.
