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...

Background: Species identification in commercially processed food and feed products is one of the important issues. This study was conducted to develop a genetic method for the detection of pig and cattle species in processed food and feed products using newly designed species-specific primers targeting mitochondrial 12S rRNA gene fragments. Methods: Two sets of specific primers were designed ...

Changes in performance traits in beef cattle over the last 30 yr necessitate the re-evaluation of central testing procedures to ensure that they are cost effective and appropriate for current test objectives. The objective of this study was to evaluate the potential for reducing the length of evaluation from 140 d to either 112 or 84 d. Data evaluated were postweaning feedlot performance test r...

Animal domestication was a major step forward in human prehistory, contributing to the emergence of more complex societies. At the time of the Neolithic transition, zebu cattle (Bos indicus) were probably the most abundant and important domestic livestock species in Southern Asia. Although archaeological evidence points toward the domestication of zebu cattle within the Indian subcontinent, the...

Neospora caninum is a worldwide distributed pathogen which causes abortion in cattle leading to economic loss in the cattle industry. The aim of this study was to determine the seroprevalence of N. caninum antibodies in the native cattle slaughtered in various areas of Kurdistan province (western Iran) from September 2010 to September 2011. Serum samples from 368 cattle slaugh...

BACKGROUND Bovine paratuberculosis is an incurable chronic granulomatous enteritis caused by Mycobacterium avium subspecies paratuberculosis (MAP). The prevalence of MAP in the Swiss cattle population is hard to estimate, since only a few cases of clinical paratuberculosis are reported to the Swiss Federal Food Safety and Veterinary Office each year.Fecal samples from 1,339 cattle (855 animals ...

Camels are getting increasingly important for pastoral livestock systems in arid and semi-arid rangelands of East Africa that adversely affected by climate change. Cattle more susceptible to drought than camels rely on grass, while primarily browsers. Diet selection can influence the quality milk, especially milk fat. Little is known about differences fatty acid profile compared cattle, under f...

The present study was carried out to validate the single nucleotide polymorphism (SNP) in mitochondrial gene- cytochrome b oxidase at 14,716 bp (C T transition) position obtained from whole genome sequence data of indigenous cattle breeds Department Animal Genetics and Breeding, Madras Veterinary College, Tamil Nadu. A total 288 animals, viz. Alambadi (16), Bargur (99), Kangayam (54), Pulikulam...

Abstract: In order to investigate the seroprevalence of Neospora caninum infection in cattle in Southwestern Iran, blood samples were collected from Holstein (121 animals) and cross-breed (436 animals) cattle from three farms and seven areas of Ahvaz, respectively. All of the Holstein cattle were “4 years old but cross-breed cattle were from different age groups ( < 2, 2-4, 5-6 and > 6 years ol...
