for determining the fatty acid characteristics and biodiesel quality of ethiopian jatropha provenances, the study was conducted in five regions namely southern nation nationalities peoples regional state (snnprs), amhara region, tigria region, oromia region and benishangul gumuz regions, where physic nut is found abundantly. for each region, representative sampling sites were selected following...

The amino acids in an acid hydrolysate of casein were catabolized more extensively by Megasphaera elsdenii than those in an enzymic hydrolysate. Threonine and serine were most actively degraded, but no resultant increase in growth yield occurred. Branched-chain volatile fatty acid production, which increased as the dilution rate of a glucose-limited chemostat decreased, seemed to be associated ...

The rumen is arguably the most important organ in the ruminant digestive system. Ruminal microbial protein and volatile fatty acid (VFA) synthesis supply most of the protein and energy needs of the ruminant. Rumen function problems can reduce intake, digestion, and health of ruminants and culminate in death. Furthermore, inefficient rumen function reduces animal performance and health and contr...

The effect of phosphorus supplementation to ammoniated rice straw was studied. The in vitro experiment was carried out following the first stage of Tilley and Terry method. The treatments consisting of four diets were A= 50% ammoniated rice straw + 50% concentrate (control), B= A + 0.2% phosphorus (P) supplement, C= A + 0.4% phosphorus (P) supplement, and D= A + 0.6% phosphorus (P) supplement o...

Abstract The effect of pH and extraction temperature on flux, recovery, mass transfer coefficient separation factor volatile fatty acids (VFAs) alcohols from synthetic solutions cheese whey fermentate was investigated using a silicone membrane contactor with water as extractant. allowed undissociated only, resulting in substantially higher recovery efficiencies at 3 than 5. Furthermore, the non...
