This study was conducted to investigate some factors affecting nutritive value using fermentation gas production technique (Pressure transducer for In-vitro cumulative gas production techniques. Four buffers: (BUF1= MENKE AND STEINGASS (1988). BUF2= GOERING AND VANSEOST (1970. BUF3= THEODORUE (1993). BUF4= STEINGASS (1983)) were used with two different ratios of rumen liquid buffers: (1:2 and 1:3), two different sizes of rumen liquid for incubation (30 ml and 60 ml), two feedstuffs samples weights (200sw1-600sw2 mg) have been investigated. Various feedstuffs were evaluated: Roughages (rice straw RS), corn stover CS), sugar cane bagasse SCB) and Alfalfa hay AA)). Concentrate (soybean meal SBM) - cottonseed meal CSM) - concentrate feed mix CFM) and corn C) ). Results showed that the highest gas emitted was found with BUF2 (GOERING and VANSEOST (1970) and the lowest was with BUF3 (THEODORUE (1993). Differences were significant (P |
