There are 21 pluck shops/ cottage poultry processors in the county, 14 pluck shops were randomly selected for the study. Samples consisted of 28 broiler carcasses, 14 wash wa...

Food safety and shelf-life are both important microbial concerns in relation to broiler meat production. Focus is mainly placed on the absence or control of potentially pathogenic microbes such as Salmonella spp. and Campylobacter spp. but, from the commercial point of view, other spoilage bacteria also play a role as potential threats. Regarding food safety, the primary target should be the pr...

The article presents the results of studying impact spore-forming probiotic “Olin” and prebiotic “Eсofiltrum” on meat quality broiler chicken carcasses Ross-308 cross. In course research, it has been found that inclusion these preparations in diet a positive effect studied indicators: pre-slaughter weight increased by 4.3-5.7%, gutted carcass 4.6-6.2%, muscle 4.8-6.5%, loin muscles 5.7-8.2%. ra...

Reducing the Campylobacter load on poultry carcasses represents a major tasks for industry as its ability to reduce their presence is of interest aiming increase consumer safety. This study investigated mixture natural antimicrobials (A3001) adherence T6SS+/? C. coli isolates (NC1hcp-, NC2 hcp- and NC3 hcp+) chicken neck skin whole carcasses. Overall, antimicrobial induced significant reduction...

Commercial layer-type, pullet, cockerel, and broiler chicken flocks infected with highly pathogenic avian influenza (HPAI) H5N1 in Nigeria between 2006 and 2008 were investigated for morbidity, mortality, and pathology. Of the one hundred and fifty-three (153) farms confirmed with HPAI infection, one hundred and twenty-seven (127) were layer-type farms, nine (9) were pullet and broiler farms ea...

We consider a feature selection method to detect skin tumors on chicken carcasses using hyperspectral data. A chicken skin tumor is an ulcerous lesion that is surrounded by a rim of thickened skin. Detection of chicken tumors is a difficult detection problem because chicken tumors are of many sizes and shapes; some tumors appear on the side of chicken. In addition, different areas of normal chi...

Forty-eight, 27-week-old White Leghorn hens were fed a diet containing 0, 1.25, 2.5 or 5.0% conjugated linoleic acid (CLA) for 12 weeks. At the end of the 12-week feeding trial, hens were slaughtered, and boneless, skinless breast and leg meats were separated from carcasses. Meats were ground through 9 and 3-mm plates, and patties were prepared. Patties prepared from each dietary treatment were...
