Methane (CH4) is produced as a result of anaerobic fermentation of the soluble and structural carbohydrates by methanogens in the rumen of ruminant animals, which is released into the environment by eructation. Methane production from ruminant range from 2 to 12% of the gross energy intake and represents a substantial loss in efficiency of animal production. Recently, CH4 production by ruminants has also received attention due to its contribution to global warming. Much research has been carried out on the manipulation of rumen fermentation to inhibit methanogenesis. Several strategies can be treated to reduce CH4 production in the rumen such as by feed manipulation (composition, feeding level) or by the use of both chemical and natural feed additives. More biotechnological interventions e.g., defaunation, probiotics and prebiotics, and introduction of reductive acetogenesis in the rumen, are also mentioned. Chemical inhibitors have proved to be effective in decreasing CH4 production to variying degrees. Problems with chemical inhibitors have been noted, such as rumen microbial adaptation, toxicity to the host, residues in endible products and an inability to increase energetic efficiency.

The research was aimed to evaluate the effect of using cassava starch on the quality and acceptability of meatball. Six kilograms of ground beef meat which have been well mixed with spices of salt, garlic and pepper were divided into 5 sub-groups. Each sub-group of dough was mixed with 5 difrerent levels of cassava starch of 0 % (R0), 5 % (R1), 10 % (R2), 15 % (R3) and 20 % (R4), respectively. The dough were then made in small ball form (meatball) and subdivided into 4 sub-sub-groups as replications. The raw dough of meat ball was then cooked in boiling water for 15 minutes to produce ready to eat meatball products. The products were measured for pH, moisture and protein content, and acceptability. Results indicated that pH, moisture and protein content of the meatball were decreased significantly (P<0,01) by increasing the use of cassava starch. Acceptability of meatball by test consumers, however, was not significantly affected by the use of cassava starch. Therefore, cassava starch could be used up to 20 % in making meat ball.
