In this study, we determined species-specific variations by analyzing the mitochondrial 12S rRNA gene sequence variation (∼440 bp) in 17 newly obtained sequences and 90 published cattle, yak, buffalo, goat, and pig sequences, which represent 62 breeds and 17 geographic regions. Based on the defined species-specific variations, two endonucleases, Alu I and Bfa I, were selected for species authen...

The number of meat recalls has increased markedly in recent years. This research examines the impact of beef and pork recall announcements on nearby daily live cattle and lean hog futures market prices, respectively. Results indicate medium-sized beef recalls that are of serious health concerns have a marginally negative impact on short-term live cattle futures prices. However, results are not ...

We surveyed β-lactamase-producing Escherichia coli from farm animals (chickens, pigs, and cattle) and raw retail meat in Shizuoka Prefecture, Japan. In total 305 E. coli isolates, 15 isolates collected from broilers, beef cattle, chicken meat, and pork meat, were found to have β-lactamase genes encoding CTX-M-2, CTX-M-14, CMY-2, SHV-2, and/or TEM-1, whereas 7 possessed mutations in the ampC pro...

were passing meat inspection. Meat inspectors were requested to submit lymph nodes that appeared abnormal as to size, color, or consistency. A total of 2843 dairy animals3 and 6791 beef animals was inspected on collection days. Lymph nodes were submitted from 736 cattle. Four dairy cattle were found to have malignant lymphoma following the histopathologic study. Two of these cows with extensive...

Fifty Angus x Shorthorn heifers (mean body weight, 384 kg) were used to investigate the effects of a 72 h pre-slaughter fast and cold environmental conditions (accentuated by wetting down) on meat colour, muscle ultimate pH (pHu) and gusceptibility to bruising. Cattle fasted outdoors and wet down had a higher muscle pHu than cattle fasted in a shed (5.51 vs 5.37: P < 0.05) and a darker meat col...

A significant challenge facing the world today is the expected 34% increase in the human population by 2050, which will require 70% more food from existing natural and land resources (FAO, 2009). Thus, the efficiency of natural resource use must be improved to meet the food security goals for a growing population while protecting the environment (FAO, 2009). Due to their ability to utilize cell...

Meat animals are unique as experimental models for both lipid metabolism and adipocyte studies because of their direct economic value for animal production. This paper discusses the principles that regulate adipogenesis in major meat animals (beef cattle, dairy cattle, and pigs), the definition of adipose depot-specific regulation of lipid metabolism or adipogenesis, and introduces the potentia...

BACKGROUND A study to curb transmission cycle of a zoonotic Taenia cestodiasis between humans and cattle is presented. OBJECTIVE To evaluate the reliability of meat inspection procedure in detecting carcasses of cattle with T. saginata cysticercosis. METHODS A total of 55 cattle divided into two groups of artificially (n=30) and naturally (n= 25) infested animals were utilized. Total dissec...

Simple and reliable conventional multiplex-polymerase chain reaction (multiplex-PCR) as well as real-time PCR approaches for the partial-length cytochrome b or cyt b gene of mitochondrial DNA (mtDNA) were compared to identify seven animal species for the authenticity of low non Halal (pig, dog, cat and donkey) and high value Halal (cattle, sheep and goat) meats. Either analysis indicated the su...

The fatty acid composition of the intramuscular lipids of cattle, pigs and birds were determined relative to breed and feeding regime. The cattle included Yellow Cattle, Hereford and Japanese Black; pigs included Wild-boar, Touyuens and Yorkshires; the birds were Wild-birds, Jungle-fowl and broilers. The pen fed animals such as Japanese Black cattle and Yorkshire pigs had a higher amounts of ol...
