บทคัดย่อ (EN): This experiment was to investigate the effect of mao seed (MS) levels on digestibility and rumen gas production by using in vitro gas production techniques. The experimental design was a completely randomized design (CRD) and the dietary treatments were MS supplementation at 0, 4, 8, 12, 16 and 20 mg with 0.5 g of roughage and concentrate ratio at 60:40. The results revealed that the intercept value (a), gas production from the insoluble fraction (b), gas production rate (c), potential extent of gas production (a+b) and cumulative gas production (72 h of incubation) were not significantly different among treatments (P>0.05). Supplementing with MS had not affected on in vitro dry matter degradability (IVDMD), true digestibility and NH3 -N concentrations (P>0.05). Moreover, supplementing MS linearly decreased in in vitro organic matter degradability (IVOMD). Populations of protozoa tended to decrease when increasing level of MS (P=0.06). Based on this study, it could be concluded that supplementation of MS at 8 mg could be efficiently utilized in rumen in term of reduced protozoal population and maintaining the digestibility and in vitro gas production.
