Abstract


The slaughterhouse of Cotonou and the surfaces of slaughtering of Porto-Novo, Abomey-Calavi, Sèmè-Kpodji and Ouidah constitute sources of animal solid matter flow in Large Nokoué. Within the framework of this research, it is refers to the contents of paunches considered for their potential of valorization in the production of biogas and the compost. Then, the quantitative evaluation their layers is a contribution to the efficient use of those as resources or raw materials, for a planning of future management. The methodological approach used is centered on the document retrieval, the datagathering by measurements or weighing of the roughs weight of contents of paunch of the animal species using balance of brand CAMRY as well as recovery of the statistics of slaughtering in the structures in charge of the breeding and the services of inspection of the activities of slaughtering units. The data obtained were treated then the analyzed results. The sample size selected is of 50 individuals of species cattle and 50 individuals of species of caprine sheep. The data analysis was analyzed, inter alia, thanks to software SPSS version 17.0 was used for the statistical analyses. It comes out from this research that each shot down cattle generate 48.5612 kg of waste (contained digestive). It is advisable to recall that the majority of the cattle taken as sample is race zebu and bull-fighting. As for the sheep and goats, each animal generates a quantity of approximately 4.0364 kg of waste. With this average of 48.5612 kg of contents of bovine paunch, and 4.0364 kg for the sheep and goats, the layer of contents the digestive ones was estimated at 1060 tons for the year 2011, and at 1298 tons for the year 2015 at the level of Large Nokoué. If this trend is maintained, this layer could border 2011 tons by 2030. The evaluation of the layers of contents of paunch produces by the activities of demolition the sector of the study regarded as largest parts of the fractions which may undergo beneficiation of the livestock wastes takes part in the installation of strategies of perpetuation of the actions of treatment and valorization within the framework of a sector.
