Tropical tree foliage supplementation in ruminants improves rumen fermentation and the bacterial profile and decreases methane production
The main of this study was to evaluate the effect of supplementation of tropical tree foliagein ruminant diets on thein vitro fermentation, bacterial population, volatile fatty acids (VFAs), and enteric CH4 production. Seven experimental diets were evaluated: a control treatment of Pennisetum purpureum (T7) and six treatments ofP. purpureum supplemented (30%) with the foliage of Neomillspaughia emargiata (T1),Tabernaemontana amygdalifolia (T2), Caesalpinia gaumeri (T3), Piscidia piscipula (T4), Leucaena leucocephala (T5), and Havardia albicans (T6). The T2, T7, and T5 treatments had the highest (p<0.05) digestibility of dry matter. Overall, supplementation increased (p<0.05) the concentrations of propionicand butyric acid and decreased acetic acid. Methanogenic bacteria decreased (p<0.05) in T1, T2, T5, and T6. Ruminococcus albus decreased in T1, T2, T3, and T5 and Selenomonas ruminiantum increased in T3. Fibrobacter succinogenes increased, except in T5. Methane production decreased (p<0.05) in T1, T4, T5, and T6. The supplementation with Leucaena leucocephala, Tabernaemontana amygdalifolia, Neomillspaughia emargiata, Piscidia piscipula, Havardia albicans, and Caesalpinia gaumeriis a potential alternative nutritional strategy forruminants that results in positive changes in VFAs profile, a decrease on CH4 production and methanogenic bacteria, and changes on fibrolytic and non-fibrolytic bacteriacomposition.
