For over a century, the word temperament has been used to define the fear-related behavioral responses of cattle when exposed to human handling. As cattle temperament worsens, their response to human contact or any other handling procedures becomes more excitable. Within the beef cattle industry, producers select cattle for temperament primarily for safety reasons. However, recent studies demon...

Seroprevalence of brucellosis in 1473 cattle and 481 buffaloes from various Government and 286 cattle and 223 buffaloes from different private livestock farms was carried out by performing Rose Bengal plate test (RBPT) and serum agglutination test (SAT). RBPT recorded the seroprevalence as 14.70% in cattle and 15.38% in buffaloes at Government and 18.53% in cattle and 35.40% in buffaloes at var...

871 mesenteric lymph nodes taken from 110 native cattle from Urmia slaughter-house with differentages were examined for Linguatula serrata infection. The lymph nodes were studied based on their colourand consistency. 44% of the cattle were found positive for L. serrata infection. The number of parasitesisolated from each infected lymph node varied from 1 to 69 with a mean of 5.48. There were no...

Introduction During the 1980s, the beef slaughtering industry became increasingly concentrated. In 1980 the four largest packers slaughtered 36% of fed cattle nationally and marketed 53% of boxed beef. By 1989 the four largest firms slaughtered approximately 69% of the fed cattle and marketed more than 80% of the boxed beef (Purcell 1990a; Lambert 1990). Concentration is even higher in some reg...

The utility and documentation of traits and characteristics of Zebu, Bos indicus, cattle in beef production in the United States are discussed with reference to adaptation. Zebu cattle are uniquely suited to hot climates due to coat, hide, skin and hematological attributes. Form, growth and physiological aspects are unique genetic attributes which are different from those of Bos taurus cattle. ...

The objective of this study was to investigate the correlation between cattle breeds and deposit of adipose tissues in different positions and the gene expressions of peroxisome proliferator-activated receptor gamma (PPARγ), fatty acid synthase (FASN), and Acyl-CoA dehydrogenase (ACADM), which are associated with lipid metabolism and are valuable for understanding the physiology in fat depot an...

Leptin plays an important role in the regulation of feed intake, energy metabolism, growth and reproduction of cattle. We used the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique to screen for DNA polymorphisms of the leptin gene in 403 cattle belonging to various breeds of Bos indicus (Hariana, Sahiwal, Gir and Nimari cattle), Bos taurus (Holstein Friesi...

During 2003-2007, deaths occurring in the production of crops and animals in the United States totaled 2,334; of these, 108 (5%) involved cattle as either the primary or secondary cause. During the same period, Iowa, Kansas, Missouri, and Nebraska accounted for 16% of the nation's approximately 985,000 cattle operations and 21% of the nation's cattle and calf herd. To better characterize cattle...

although the high infection rate of microscopic sarcocyst occurs in cattle, to the best of our knowledge,there is no report about the identification of macroscopic sarcocyst in iran. in this work, sarcosystis hirsutawas first isolated from slaughtered cattle. in a 2-year-old slaughtered cattle, morphological examinationrevealed 3-5 mm in length cysts distributed in different striated muscles, p...

in order to investigate the prevalence and detection of etiological agents of pyelonephritis in shahrekordabattoir, 404 kidneys of slaughtered cattle (207 female and 197 male) were inspected. kidney samples, whichhad gross changes were obtained for histological examination. urine and renal tissue samples were alsocollected aseptically for microbiological examination. in histological examination...
