Type: conference-paper
Abstract: A prior study shown that the best combination of hibiscus leaf 0.3 mg/ml (Supplement 1) and tea by-product 2 mg/ml might enhance VFA synthesis. This study aimed to evaluate the impact of a mixture of Syzygium aromaticum oil, Camellia sinensis leaf meal, and Hibiscus rosa-sinensis on the in vitro fermentability and digestibility of rumen. There were five replications and four treatments in the fully randomized block design experiment. Among the therapies were the following: As a control, A1 uses forage:concentrate (60:40% DM); A2 uses control plus Supplement 1; A3 uses control plus Supplement 1 plus 0.02 mg/ml S. aromaticum oil; and A4 uses control plus Supplement 1 plus 0.04 mg/ml S. aromaticum oil. The following variables were noted: pH value, total volatile fatty acid (VFA) generation, ammonia (NH3) concentration, dry matter digestibility (DMD), organic matter digestibility (OMD), pH, total gas output, ammonia (NH3) concentration, and total volatile fatty acid (VFA) generation. The results indicated that adding 0.04 mg/ml of S. aromaticum oil enhanced total VFA (p<0.01), decreased DMD (P<0.01), lowered OMD, and decreased total gas production (P<0.1). There was no discernible difference between pH levels and NH3 concentrations (P>0.05). In summary, rumen fermentation characteristics may be stimulated by adding up to 0.04 mg/ml of S. aromaticum oil.
