Relationship between protozoa, digestibility and methane production in rumen: a molecular comparative approach between ruminants and camels protozoal fauna
Description: Recently, Canada made an agreement to reduce CH4 emissions. In agricultural, methane is mainly produced by the dairy sector and a large part comes from the animal himself due the rumination. Improving the rumination efficiency could be a way to be a part of the national reduction effort. Ruminants and camels are herbivores evolved to use fibrous roughage. The compartmental stomach retains feed and provides the requirements for the diverse microbial population it hosts like bacteria and protozoa. The microbial population ferments fibrous feeds, producing microbial protein and as a fermentation by-product, volatile fatty acids. These provide an energy source that the host animal can use for maintenance and well as for performance, such as growth and milk production. Protozoa species in camelids are different and allow better cell-wall degradation in the rumen; furthemore methane production is reduced as compared to other ruminants. Thus, it seems that the presence of protozoa in the rumen may increase forage digestibility by up to 30%. Molecular characterization of camel microflora and its comparison with those of other ruminants will provide information about their diversity, along with their role and mode of action. This study is about the characterization of the population of ciliated protozoa and methanogens population in the camel and bovine rumen by the PCR technology. Assume identified in camels highly efficient microbial population whose rumen of ruminants devoid that might be transferable in ruminants to improving their digestibility of forages and improving their production as well as decreasing their methane emissions.
