Fifty-two Angus x Gelbvieh rotationally crossed virgin, ovariectomized, or single-calf heifers were slaughtered after 100 d on a high-concentrate diet. Heifers from each treatment were approximately 31, 33, or 35 mo of age, and they produced 31 A, 5 B, and 16 C maturity carcasses. Because of the small number, B maturity carcasses were not included in this study. Number of A maturity carcasses d...

A study was conducted in order to evaluate the contamination by Brucella spp. of meat from animals slaughtered because they had resulted positive for brucellosis at some time during their life. After slaughter and before delivery to market outlets, swab samples were taken from 307 carcasses of infected animals: 40 cattle, 60 sheep and 207 goats. The swabs were subsequently analysed by means of ...

The study results of Aberdeen-Angus breed bull meat production, depending on the body type, are presented. first group consisted bulls descended from stud large tall second small compact type. It was determined that at age 18 months, large-type parents reached a weight 442 kg, and small-type - 413 kg. had higher pre-slaughter by 31.4 kg heavy carcasses compared to 28.3 or 13.5% (P > 0.99). b...

Recent research has demonstrated how scavenging, the act of consuming dead animals, plays a key role in ecosystem structure, functioning, and stability. A growing number of studies suggest that vertebrate scavengers also provide key ecosystem services, the benefits humans gain from the natural world, particularly in the removal of carcasses from the environment. An increasing proportion of the ...

During processing, fecal material may contact broiler carcasses externally or internally. A study was conducted to determine the effect of external vs. internal fecal contamination on numbers of bacteria on broiler carcasses. In each of 3 trials, 12 carcasses just prior to evisceration were obtained from a commercial processing plant, placed on a shackle line, and eviscerated with commercial eq...

High quality pork is consumed as fresh meat, whereas other carcasses are used in the processing industry. Meat quality is determined measuring technical muscle variables. The objective of this research was to investigate the molecular regulatory mechanisms underlying meat quality differences of pork originating from genetically different Piétrain boars. Piétrain boars were approved for high mea...

The objective of this study was to evaluate the effects of sequential applications of ɛ-polylysine (EPL) or lauramide arginine ethyl ester (LAE) sprays followed by an acidic calcium sulfate (ACS) spray on inoculated chicken carcasses to reduce Salmonella (Salmonella enterica serovars including Salmonella typhimurium and Salmonella enteritidis) contamination during 6 days of storage (4.4°C). Sec...

A study on the prevalence and levels of Campylobacter, Salmonella and E. coli on broiler chicken carcasses, wash and rinse water from pluck shops/ cottage poultry processors (CPP) in county Nariva Mayaro Trinidad was done. 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...
