Microbiological quality of commercially available poultry feeds sold in Bangladesh

Abstract

Abstract:The study was conducted aiming at the isolation and identification of pathogens from poultry feed manufactured by four different brands namely A (broiler starter), B (broiler finisher), C (layer starter) and D (layer finisher) sold in retail stores of Rangpur city of Bangladesh. All these samples were collected from four randomly chosen outlets and analyzed by culturing in different culture media such as Nutrient broth (NB), Nutrient agar (NA), Salmonella-Shigella (SS) agar, Eosin methylene blue (EMB) agar, MacConkey agar, Triple sugar iron (TSI) agar slant, Motility, Indole, Urease (MIU) and Saboraud Dextrose agar (SDA) media. The bacterial agents were isolated and examined under light microscope for their gross morphological and conventional biochemical characteristics. The bacteriological analyses were done at the Microbiology

Prevalence and Antimicrobial Resistance Profiles of Salmonella Species and Escherichia coli Isolates from Poultry Feeds in Ruiru Sub - County, Kenya

“…The prevalence of 58% of Escherichia coli obtained was similar to a related study carried out in Bangladesh with a prevalence of 57% [27]. Other related studies reported different prevalence of 16% in Iraq [1] and in Nigeria 10.6% and 11% respectively [29,16].…”

“…A prevalence of 28% of Salmonella sp. in poultry feeds recorded was similar to a prevalence of 29% reported in Tanzania [26] and Bangladesh [27]. Nevertheless, studies in Africa have continued to show varying results.…”

The occurrence of drug-resistant bacteria and screening the possible presence of residual antibiotics in poultry feed samples

“…Poultry feed comprises mainly grains such as maize, wheat, barley, cake meal, sunflower seeds, peanuts and animal protein products such as fish meal, meat or bone meal, etc. (4,6,7). Depending on the functions they perform in the birds, different categories of poultry feeds exist inclusive of starter, growers, finishers, layers etc.…”

“…Depending on the functions they perform in the birds, different categories of poultry feeds exist inclusive of starter, growers, finishers, layers etc. (7).…”

“…Major feed contaminants include moulds, mycotoxins and bacteria which may be responsible for various poultry diseases like cholera, colibacillosis, listeriosis, staphylococcosis, amoebic dysentery, bacillary dysentery, salmonellosis, avian influenza, newcastle disease, infectious coryza etc. (1,3,7,10).
