Abstract
This study was conducted in order to determine and investigate the bacterial contamination of commercial poultry feeds marketed in Khartoum state. A Total of (45) samples of three different commercial poultry feed namely, pre starter for chicks, broiler finisher and layer finisher obtained from five localities in Khartoum state namely ( Sharg Alneel , Khartoum , Bahri , Omdurman and Jabel Awliaa ) were examined for their microbiological quality using microbiological and analytical methods. The mean total bacterial counts vary within the samples of the three types of poultry feeds while statistical analysis revealed no significant difference between mean of the three type of poultry feeds. Statistical analysis also revealed a high significant difference in the mean of total bacterial counts for the five localities (P≤0.01), and the highest mean of total bacterial counts found in Jabel Aweliaa locality was (5.71) log10 CFUcm, while the least in Bahri locality was (4.57) log10 CFUcm. Three genera of bacteria were isolated and their percentage occurrence was Escherichia coli (60%), salmonella spp (53.33%) and staphylococcus aureus (26.66%). Proximate composition showed a different variation in moisture, ash, fat, crude fiber and protein content among the experimental samples obtained from Bahri and Jebel Aweliaa localities. Approximate analysis indicated a deterioration in nutritive value specifically protein percent for samples collected from Jabel Aweliaa locality which showed highest bacterial contamination in it. The obtained results indicated, the tested samples of commercial poultry feeds marketed in Khartoum State contain contaminants.
