fasciolosis is a disease caused by liver fluck of the genus of fasciola. diagnosis of fasciolosis has been challenging for a long period due to low sensitivity of the coprological diagnostic method. in this study, an in-house dot-elisa method; using excretion–secretory (es ag) and crude (cr ag) antigens of fasciola was described for diagnosis of fasciolosis in cattle. for this purpose, the sera...

background: heavy metals contaminated environment constitutes a serious problem for human and other organisms. moreover, metals such as cd, pb, and cr are toxic metals. therefore, the purpose of this study was to evaluation of cd, pb, and cr in the muscle of cow, calf, and sheep slaughtered in sanandaj city from iran. methods: this was a descriptive cross-sectional study in sanandaj city in nov...

The prevalence of Toxoplasma (T.) gondii was surveyed using a latex agglutination test (LAT) in native Korean cattle. A blood sample was collected from female 105 cattle in the Daejeon area of Korea. All cattle were asymptomatic and had not received any prophylactic treatment for T. gondii. Blood samples were collected via the caudal vein. The cattle ranged in age from 2~6 years (mean 3.7 years...

Epidemiology of fasciolosis was studied at slaughter houses, livestock farms, veterinary hospital and on household cattle under different managemental conditions. Infection rate was 22.6%, 17.5%, 10.82% and 8.76% respectively in slaughtered cattle, cattle at livestock farms, veterinary hospitals and household cattle. Overall highest seasonal prevalence in all types of cattle was recorded during...

Pasturing of livestock in forests has had profound consequences for Europe's landscapes. In Białowieża Primeval Forest (BPF), cattle pasturing was a part of traditional forest use that ceased only in the second half of the twentieth century. We collected information on the institutional changes governing forest cattle pasturing and the changes in spatial extent of cattle presence in BPF in last...

This study compares the prevalence of ixodid tick species on cattle and goats in Maputo Province. Adult ticks as well as the nymphs of three species, and only the adults of two species were collected from sets of five cattle at 21 localities throughout the province and compared with those collected from similar sets of goats at the same places. Amblyomma hebraeum adults and/or nymphs were prese...

Information about genetic diversity and population structure among cattle breeds is essential for genetic improvement, understanding of environmental adaptation as well as utilization and conservation of cattle breeds. This study investigated genetic diversity and the population structure among six cattle breeds in South African (SA) including Afrikaner (n = 44), Nguni (n = 54), Drakensberger (...

Crossbred horned steers and heifers (n = 40; BW = 311.8 ± 4.7 kg) were used to determine the effect of dehorning methods on pain, cattle behavior, and wound healing. Cattle were blocked by weight and randomly assigned to 1 of 4 treatments: 1) control (CON), 2) banded using high tension elastic rubber (BAND), 3) mechanically removed (MECH), or 4) tipped (TIP). Vocalization and behavior were reco...

Cattle may suffer pain and distress if incorrectly stunned. Regular monitoring of stun quality in abattoirs is now required by EU law. This study aimed to assess stun quality in cattle slaughtered under commercial conditions. A stun protocol was developed to evaluate when inadequate stunning occurred. This included rating of identified symptoms into three levels from highest to lowest risk for ...

Understanding and documenting the process of hybridization and introgression between related species is a major focus of recent evolutionary research using molecular techniques. Many North American bison herds have cattle ancestry introduced by crossbreeding over a century ago. Molecular estimates of this ancestry have shown much higher levels for cattle mtDNA than for autosomal cattle genes. A...
