this study was conducted to investigate the bacterial contamination of small ruminant carcasses in traditional slaughterhouses of tehran province, in summer and winter seasons. 30 sheep and goat carcasses from slaughterhouses of rey, shahreyar and eslamshahr were evaluated. در انتهای خط کشتار و قبل از مرحله توزیع، از لاشه دامها نمونه برداری شد. randomly samples were taken at the end of the slau...

The current experiment was conducted to evaluate the on-line application of visible and near-infrared spectroscopy (VISNIR) to US Select carcasses during commercial beef carcass grading procedures to predict tenderness of longissimus steaks after 14 days of refrigerated storage. A regression model was calibrated using 146 carcasses and tested against an additional 146 carcasses. Carcasses were ...

Feedlot producers could optimize the value of cattle in a given market grid if they were able to improve the uniformity of the body composition between cattle among loads. Allelic variation due to a single nucleotide transition (cytosine [C] to thymine [T] transition that results in a Arg25Cys) has been demonstrated to be associated with higher leptin mRNA levels in adipose tissue and increased...

this study was conducted to determine the prevalence of salmonellae contamination of chicken carcasses in slaughterhouses in central iran (yazd province). 435 samples were obtained from liver, breast— before and after chilling—and bacteriological and serological examinations were done. the results showed that the rate of contamination of liver, breast meat—before and after chiller—were 8.1, 18....

the aim of this study was to determine the principal reasons for condemnation of broiler poultry carcasses and its economic losses in namin slaughter-house of iran from  february 2008 to  march 2009 . in this period, 2741794 poultry were slaughtered which were7662237 kg live weight and 5560963 kg eviscerated meat .from these , 20479 carcasses responsible for 0.74% of total slaughter with overal...

Our objective was to determine the effect of repeated use of implants on feedlot performance and carcass characteristics of Holstein cattle. Holstein steers (n = 128) weighing an average of 211 kg were blocked by weight and randomly assigned to 16 pens. At the start of the trial (d 0), pens were assigned to one of four treatments: 1) nonimplanted control (C); 2) implant on d 0, 112, and 224 (T3...

The aim of this study was to determine the frequency of enterotoxigenic and enteroaggregative strains ofEscherichia coli in chicken carcasses by polymerase chain reaction (PCR). In this study 63 strains of E. coliwere isolated from 110 samples of chicken carcasses during processing after chilling in the poultry slaughterhouse of Shahrekord. Polymerase chain reaction assays were used to detect t...

This study was carried out to determine the prevalence of foodborne pathogens, Escherichia coli, E. coli O157:H7, Listeria monocytogenes and Campylobacter spp. on slaughtered cattle in Isfahan, Iran. A total of 203 cattle carcasses were sampled by surface section of neck meat taken immediately after slaughter and analyzed using microbiological examinations. Suspected colonies to E. coli O157:H7...

There is much interest in understanding how anthropogenic food resources subsidise carnivore populations. Carcasses of hunter-shot ungulates are a potentially substantial food source for mammalian carnivores. The sambar deer (Rusa unicolor) is a large (≥ 150 kg) exotic ungulate that can be hunted throughout the year in south-eastern Australia, and hunters are not required to remove or bury carc...

The objective of this study was to characterize Salmonella enterica contamination on carcasses in two large U.S. commercial pork processing plants. The carcasses were sampled at three points, before scalding (prescald), after dehairing/polishing but before evisceration (preevisceration), and after chilling (chilled final). The overall prevalences of Salmonella on carcasses at these three sampli...
