(2004) suggested that protozoa transformed the starch into more butyric acid. Contrary to this view, protozoans have been suggested to play an important role in preventing lactate accumulation and controlling pH as they use lactate (Dehority, 2005).
Rezaei et al [12] found that adding molasses to ensiled Amaranthus hypochondriacus reduced the pH, butyric acid content, N[H.sub.3]-N content and cytoderm components and increased WSC content, lactic acid content, gas production levels and degradation kinetic parameters in vitro.
10 mL of anaerobic sludge sampled and inoculated to 300 mL serum bottles, and each bottle contained 100 mL propionic acid or butyric acid enrichment medium.
The concentration of butyric acids in the rumen fluids of lambs in T1 and T2 was very high compared with other groups which may support the previous hypothesis related the high glucose levels of these groups since propionate levels were low.
Fermentation characteristics reported include dry matter, pH, ammonia, acetic acid, lactic acid, propionic acid, and butyric acid (Kung and Shaver, 2001; Ward, 2000).
And for DM content, butyric acid, propionic acid, hemicellulose, NDT and MM, there was no significant effect (p > 0.05) of the interaction and of isolated factors, with mean values of 23.9; 0.03; 0.22; 26.82; 55.16 and 2.25%, respectively.
The relative mean distribution of acetic, propionic, and butyric acids of all groups was as follows: in the caecum, acetic acid 74%, propionic acid 13%, and butyric acid 13%; in proximal colon, acetic acid 75%, propionic acid 13%, and butyric acid 12%; in distal colon, acetic acid 71%, propionic acid 14%, and butyric acid 15%.
The butyric acid is considered as an anticancerigenous compound in several models of experimental carcinogenesis.
casei) and butyric acid glycerides (Baby c4) on the performance and blood chemistry of broiler chickens under commercial conditions.
Some cereal foods rich in indigestible carbohydrates lower the blood glucose response, a mechanism that has been attributed to colonic fermentation resulting in metabolites, particularly the short chain fatty acids (SCFA) acetic, proprionic and butyric acids.
The two acids identified from the culture tubes after 72 h of incubation were acetic and butyric acids (Table 3).
Propionic and butyric acids are more revolting, being the fragrance of rancid butter.
The main fermentation products that inhibit yeasts and moulds are acetic, propionic, and butyric acids in the silage; hence, the increased acetic and butyric acids in the IR and GG silages and the increased acetic acid in the WM silage could function as inhibitory substances.
Rumen metabolite revealed treatment effect for total volatile fatty acids (TVFA) acetic acid, propionic acid and butyric acids, holotrichs, spirotrichs and total protozoal population (Table 5).
