Addition of garlic powder to the ration mixture and its effect on digestion coefficient of dry and organic matter, total gas and methane in vitro production

The aim of the experiment is to find out effect garlic powder on digestion coefficient and rumen environment in vitro by adding four levels (0.0, 1.0, 2.0 3.0) g/100 g dry matter added mixture feed concentrate: roughage (40:60). Total gas was calculated 24 hours. digestibility determined after 96 hours incubation . Results showed differences (p < 0.01) total methane production, lowest value for treatment 1.0 g/100g DM , organic significantly increased (p<0.01) T3 (2.0%) with (61.28 79.87) respectively compared control. Significant difference(p<0.01) between all treatments count bacteria. Addition mix ration 60: 40 roughages : concentrate at level improve increase decrease production.
