Data on liver vitamin A concentrations in malnourished, debilitated, down cattle in tropical, northern Australia support the hypothesis that 12% annual cattle mortality was due, in part, to a slow release of liver vitamin A. High Ca and low Zn levels in the legume forage apparently contributed to the slow release. The cattle showed marked sensitivity to sunlight and exhibited problems of sight....

Fourteen percent of U.S. cattle slaughtered in 2011 had liver abscesses, resulting in reduced carcass weight, quality, and value. Liver abscesses can result from a common bacterial cause, Fusobacterium necrophorum, which inhabits rumen lesions caused by acidosis and subsequently escapes into the blood stream, is filtered by the liver, and causes abscesses in the liver. Our aim was to identify S...

In this paper conventional X-ray analysis of cattle metapodials is used to study the age structure of slaughtered cattle at Eketorp ringfort on the island of Öland, Sweden. The X-ray analyses suggest that several animals in both phases were slaughtered aged 4-8 years. More oxen/bulls than cows reached the advanced age of over 8 years, yet in phase III more oxen/bulls seem to have been slaughter...

bovine venereal campylobacteriosis, caused by campylobacter fetus subsp. venerealis (cfv), is regarded as one of the major threats to the cattle industry around the world. abortion and infertility are two important reproductive problems in cows infected with c. fetus subsp. venerealis. reports on the presence of cfv are scarce in the cattle, in iran. therefore, the present study was designed to...

fasciolosis and dicrocoeliosis are endemic parasitic diseases in middle east especially iran, which making significant economic problems. this retrospective survey has been done to evaluate contamination rate of slaughtered animals with fasciolosis and dicrocoeliosis at meisam abattoir, in tehran, iran. in this survey, prevalence rate of fasciolosis and dicrocoeliosis in slaughtered animals in ...

The surface of the intestinal mucosa is constantly assaulted by food antigens and enormous numbers of commensal microbes and their products, which are sampled by dendritic cells (DCs). Recent work shows that the mesenteric lymph nodes (MLNs) are the key site for tolerance induction to food proteins and that they also act as a firewall to prevent live commensal intestinal bacteria from penetrati...

AIM The main objectives of this study were to determine the incidence of Sarcocystis sp. infection in cattle and buffalo carcasses slaughtered at El-Kharga abattoir, New Valley Governorate, Egypt. MATERIALS AND METHODS The slaughtered animals were daily inspected for Sarcocystis macrocysts through a year (2015). Macroscopic Sarcocystis was detected from a total of 2120 cattle and buffalo carc...

Fourteen percent of U.S. cattle slaughtered in 2011 had liver abscesses, resulting in reduced carcass weight, quality, and value. Liver abscesses can result from a common bacterial cause, , which inhabits rumen lesions caused by acidosis and subsequently escapes into the blood stream, is filtered by the liver, and causes abscesses in the liver. Our aim was to identify SNP associated with liver ...

Conducting routine allergy tests of cattle with a simultaneous sample in TB-prone farms is necessary to confirm the stage epizootic process. The purpose research – explore pathomorphological changes cows upon detection para allergic reactions during diagnostic testing for tuberculosis. diagnosis tuberculosis animals was performed comprehensively using all methods control provided guidelines epi...
