Protein is one of the most important essential nutrients; it is involved in many vital functions in the body, such as growth and tissue repair, enzyme catalysis, transport and storage, coordinated movement, mechanical support, immunological protection, generation and transmission of nerve impulses, and control of metabolism, growth and cellular differentiation. Therefore, ensure adequate supply...

Metallothionein (MT) is important because it binds tightly to heavy metals to decrease their toxicity. DNA was isolated from 30 toxic metal exposed and 30 toxic metal unexposed Zebu cows. The amplified metallothionein isoform-2 (MT-2) PCR product (489 bp) was further used for PCR-RFLP and DNA sequencing. MT-2 TaqI PCR-RFLP revealed homozygous genotype (AA) except for the E23 animal (AB). The ge...

The amount of trace elements present in edible bovine tissues is of importance for both animal health and human nutrition. This study presents data on trace element concentrations in semitendinosus and cardiac muscles, livers and kidneys of 60 zebu (Bos indicus) bulls, sampled at Jimma, Ethiopia. From 28 of these bulls, blood samples were also obtained. Deficient levels of copper were found in ...

Projections for beef cattle production in Brazil for the next 10 years forecast an annual increase of about 3.5%. For the same period, a 2.22% growth in the domestic intake of beef cattle and an increase of 3.07% a year in exportation is estimated. This annual increase in exportation could reach 3.4 million tons by 2019, establishing Brazil as the main beef exporting country (MAPA/AGE, 2009). T...

Estimates of covariance components between scrotal circumference, serving capacity, days to calving, yearling and final weight were obtained for Hereford, Angus and Zebu cross cattle in temperate and tropical Australia. Analyses were carried out by restricted maximum likelihood employing a derivative-free algorithm and fitting bivariate animal models. Aspects of modeling and computational requi...

The productivity of herds may be negatively affected by inbreeding depression, and it is important to know how intense is this effect on the livestock performance. We performed a comprehensive analysis involving five Zebu breeds reared in Brazil to estimate inbreeding depression in productive and reproductive traits. Inbreeding depression was estimated for 13 traits by including the individual ...

Introduction Taurine (Bos taurus) and zebu (Bos indicus) cattle were domesticated independently in the Near East and in India respectively (Beja-Pereira et al., 2006) and are believed to have diverged 117-275,000 years ago (Bradley et al., 2006). Bos taurus cattle were introduced to Australia by European settlers in the end of the 18th century. The main B. indicus breed used for beef production...

Acrobustitis is the inflammation of distal prepuce, which can lead to a narrowing preputial ostium due stenosis or growth fibrous tissue after an inflammatory reaction. This condition usually occurs in cattle with long such as Zebu Zebu’s crossbreeds, leading animal Impotentia Coeundi, this characterized by bull's disability copulate, that leads lower herd fertility and consequent financial los...

The tribe Bovini contains a number of commercially and culturally important species, such as cattle. Understanding their evolutionary time scale is important for distinguishing between post-glacial and domestication-associated population expansions, but estimates of bovine divergence times have been hindered by a lack of reliable calibration points. We present a Bayesian phylogenetic analysis o...
