BACTERIOLOGICAL QUALITY OF COMMERCIALLY PREPARED AND SELF COMPOUNDED POULTRY FEEDS IN SOKOTO METROPOLIS, SOKOTO, NIGERIA

摘要

Evidences arising from epidemiological studies as well as from detailed experimentalinvestigations have indicated that there is strong relationship between certain feed ingredients and incidence ofbacterial infections. A total of two hundred and thirty nine (239) Poultry feed samples comprising of twohundred and four (204) commercially prepared feed and thirty five (35) self compounded feed were collectedfrom seventy six (76) identified poultry farms in Sokoto metropolis over a period of 12 months for assessingtheir microbiological (bacterial) quality. Of the total 80 questionnaires administered, 76 (95.00%) wereresponded to. Of the respondents, 53 (69.74%) indicated using commercially prepared feed while 23 (30.26%)compounded the feed by themselves. Similarly, 30.57% of the farms visited store their feed either within thepoultry pen or in an open space. Out of total (n=239), commercially prepared (n=204) and Self compounded(n=35) feed samples, 217 (90.79%) samples yielded positive bacterial growth. Based on culture andidentification, 263 bacterial species/genus were identified which include the following: Corynebacteriumpyogenes(9; 3.42%), Bacillus subtilis(60; 22.81%), Enterobacter arrogenes(6; 2.28%), Escherichia coli (57;21.67%), Listeria monocytogenes (19; 7.22%), Coagulase-negativestaphylococcus(8; 3.04%), Pasturellamultocida (3; 1.14%), Pseudomona aerogenosa (7; 2.66%), Proteus mirabilis (1; 0.38%), Proteus vulgaris (17;6.46%),Salmonella spp.(10; 3.80%), Staphylococcu aureus (44; 16.73%), Streptococcus pyogenes (17; 6.46%),Yersinia enterocolitica (3; 1.14%)and (2; 0.76%) unidentified bacterial species.The presence of the abovebacteria in all the feed samples calls for attention in the storage methods employed by the poultry and otherlivestock farmers, the warehouse condition, distributors and the sellers. This result could be used as a baselinedata in setting public health standard for poultry feeds to achieve food security concern issues
