Realizing the significant association of A1 and A2 β-casein (CSN2) polymorphism with health promoting properties and milk performance traits, the present investigation was undertaken to explore A1/A2 polymorphism in Indian zebu breed, Ongole (Bos indicus) and crossbred, Frieswal (HF × Sahiwal) cattle using allele-specific (AS)-PCR. Thirty eight Ongole cow, 124 Frieswal heifers and 48 Frieswal b...

Semen production from breeding bulls used in Artificial Insemination (AI) program is of great importance cattle breeding. Good quality semen has positive effect on the fertility cows and heifers. The aim this study was to evaluate assessed as freezing ability Red Chittagong Cattle (RCC) bull with fresh-diluted frozen semen. parameters characteristics included were volume per ejaculate (ml), per...

Malignant catarrhal fever (MCF) is a fatal disease of cattle that, in East Africa, follows contact with wildebeest excreting alcelaphine herpesvirus 1 (AlHV-1). Recently an attenuated vaccine (atAlHV-1) was tested under experimental challenge on Friesian-Holstein (FH) cattle and gave a vaccine efficacy (VE) of approximately 90%. However testing under field conditions on an East African breed, t...

The tribe Bovini comprises cattle and cattle-like species. Reconstructions of their phylogeny have so far been incomplete and have yielded conflicting conclusions about the relationship of American bison and wisent (European bison). We have compared the sequences of three mitochondrial and two Y-chromosomal DNA segments. Mitochondrial DNA indicates that four distinct maternal lineages diverged ...

Baseline surveys were conducted in the Upper West Region of Ghana to assess the distribution and densities of tsetse species, as well as the prevalence of bovine trypanosomosis. The entomological survey was designed to cover the suitable tsetse habitats along the three main rivers in the study area (i.e. Black Volta, Kulpawn and Sissili). Results indicated the presence of Glossina tachinoides i...

The objectives of the present study were to estimate the allele and genotype frequencies of the GH1/Alu I and POU1F1/Hinf I polymorphisms in beef cattle belonging to different genetic groups and to determine the effects of these polymorphisms on growth and carcass traits in cattle submitted to feedlot management, an intensive production model. Genotyping was performed on 384 animals, including ...

In Niger, the growth in local demand for milk and meat makes it necessary to consider genetic improvement of the indigenous cattle. At the Toukounous breeding station, the Azawak zebu has undergone over 50 years of line breeding for milk and meat production traits. To understand the adoption potential of improved Azawak sires in Niger, this study proposes to estimate the values that cattle keep...

The effect of different nematophagous fungi [Duddingtonia flagrans (AC001 and CG722) and Monacrosporium thaumasium (NF34)] with regard to controlling infective larvae (L3) of nematodes after gastrointestinal transit in female cattle (3/4 Holstein × Zebu) was evaluated. A total of 24 pubescent female cattle were used, weighing approximately 320 kg each one. There were three treatment groups, eac...

Several studies arduously reported that gayal (Bos frontalis) is an independent bovine species. The population size is shrinking across its distribution. In Bangladesh, it is the only wild relative of domestic cattle and also a less cared animal. Their body size is much bigger than Bangladeshi native cattle and has prominent beef type characters along with the ability to adjust in any adverse e...
