Higher IFN-γ responses to mycobacterial antigens were observed in Bos taurus (Holsteins) than in Bos indicus (Zebu) cattle which could due to differences in antigen recognition profiles between the two breeds. The present study was conducted to evaluate mycobacterial antigen recognition profiles of the two breeds. Twenty-three mycobacterial antigens were tested on 46 skin test positive (24 Zebu...

The first case of spongiform encephalopathy in a zebu (Bos indicus) was identified in a zoo in Switzerland. Although histopathologic and immunohistochemical analyses of the central nervous system indicated a diagnosis of bovine spongiform encephalopathy (BSE), molecular typing showed some features different from those of BSE in cattle (B. taurus).

Trypanosomosis is a serious cause of reduction in productivity of cattle in tsetse-fly infested areas. Baoule and other local Taurine cattle breeds in Burkina Faso are trypanotolerant. Zebuine cattle, which are also kept there are susceptible to trypanosomosis but bigger in body size. Farmers have continuously been intercrossing Baoule and Zebu animals to increase production and disease toleran...

In order to clarify the origin and genetic diversity of cattle in North Eastern Asia, this study examined mitochondrial displacement loop sequence variation and frequencies of Bos taurus and Bos indicus Y chromosome haplotypes in Japanese, Mongolian, and Korean native cattle. In mitochondrial analyses, 20% of Mongolian cattle carried B. indicus mitochondrial haplotypes, but Japanese and Korean ...

Abstract Background In evolutionary theory, divergence and speciation can arise from long periods of reproductive isolation, genetic mutation, selection environmental adaptation. After divergence, alleles either persist in their initial state (ancestral allele - AA), co-exist or be replaced by a mutated (derived -DA). this study, we aligned whole genome sequences individuals the Bovinae subfami...

Two cases of Squamous cell carcinoma are recorded in zebu cattle of Tirupati, Andhra Pradesh. Lesions showed different clinical aspects Papule and cauliflower like growths placed at level of nictinating membrane of eye and interdigital spaces of hind limb respectively. Cytology and histopathological examination revealed well and poorly differentiated squamous cell carcinomas respectively.

The aim of this study was to assess the process and extent of sedentarisation among Fulani cattle owners in the derived savannah zone of south-west Nigeria. The results, based on a survey of 66 randomly-selected cattle owners, indicate an on-going process of settlement. Previously cattle owners visited the zone for dry season grazing but an increasing number were found to be settling and becomi...

The basic objectives and procedures for successful crossbreeding of beef cattle were considered, with special reference to the levels of realized hybrid vigor that might be anticipated for different crossbreeding programs involving the American Brahman (Z1) and European (Ej) breeds. Intralocus heterozygosis levels with respect to breed origin of genes (breed heterozygosis) were computed for var...

Zebu breeds of cattle from southern part of India are well known for their adaptability to extreme climatic conditions, draught efficiency, disease resistance and poor nutritional environment. Selection of appropriate populations for conservation of such genetic resources is needed in view of preventing rapid erosion of animal genetic resources. Estimation of genetic diversity is essential to d...
