Online published on 13 November, 2019. Abstract Feeds is the common constituents includes vitamins, soya beans, whole cereals and vegetables. For Salmonella and Escherichia successful control, the feed should be exposed to 85.7°c temperature because of spores are heat resistant. Crops of oilseed and grains shows the presence of diverse microflora, and to low moisture content these are highly resistant. As with natural microbial contaminants of feed, the inoculation's primary vector is soil. Animal feces mixed soil can contaminate the crops which are standing by direct deposition or if used as fertilizer. Lowering the feeds pH (haylage, silage) or feeds which are dry (meat meals, grains) may considerably reduce the activities of spoilage and allows the long time storage of animal feeds. Cl. Perfringens, Cl. Botulinum, Listeria, E.coli, Salmonella and other pathogens are involved in the pathogenesis of the poultry feeds. Cl. Botulinum is an obligate anaerobe, generally associated with silage, haylage, and contaminated carion. Listeria spp. are not possessing spore cycle, but may survive for 10–12 years. Strains of E. coli are normal microflora of human and animal intestine, and hence serves as feeds fecal contaminant. Salmonella is ubiquitous in nature and can spread horizontally and vertically throughout the livestock herd or poultry flock. In grains and feed other pathogens also may be present, though their routes of transmission are not clear. Various methods are used to avoid and treat the contamination of feed like rapid drying, shortening the time of storage, soybean oil supplementation and other chemical treatment methods are also included.
