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) - cotton seed 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 |
