Seasonal variations in plasma glucocorticoid levels in yaks (Poephagus grunniens L.) (Bos grunniens)

Tropical Animal Health and Production, 2009
The changes of glucocorticoid concentrations were measured by highly sensitive enzymeimmunoassay procedures using second antibody coating technique and cortisol -HRP amplified system for one whole calendar year in yaks. The year was divided into seasons of cool, intermediate and hot seasons.

The subpleural pulmonary microvasculature in newborn yak (Bos grunniens)

Veterinary Research Communications, 2008
Yak is a unique domestic animal of Qinghai-Tibetan Plateau. Its unique adaptability to the high altitude environment has been hypothesized due to special pulmonary microvasculature. However, the anatomical evidence is still less. The present study characterized the subpleural pulmonary microvascular architecture of newborn yak by vascular corrosion ...

Polymorphism in Mitochondrial DNA (mtDNA) of Yak (Bos grunniens)

Biochemical Genetics, 2002
Mitochondrial DNAs (mtDNA) from 21 yaks (Bos grunniens) were assayed for restriction fragment length polymorphisms by using 20 restriction endonucleases, six of which (AvaI, AvaII, BgIII, EcoRI, HindIII, and HpaI) detected polymorphism. Four different mtDNA haplotypes were identified.

Yak (Bos grunniens)

The yaks are long-haired humped bovid, a multipurpose animal that can survive in a low oxygen and cold environment at an elevation of 2000 to 6000 meters above sea level. The animal has the ability to graze diverse foliage from coarse shrubs to short grasses. The majority of yak population is still living in central Asian highlands, which include parts

Evaluation of foot and mouth vaccination for yak (Bos grunniens) in Pakistan

Tropical Animal Health and Production, 2017
In northern Pakistan, many farming communities rely on domestic yak (Bos grunniens) as a principle source of income. A 2006 participatory disease surveillance report from this region indicated that foot-and-mouth disease (FMD) is the most prevalent annual disease of yak. Our objectives of this study were to determine exposure levels of yak to FMD virus;

Cytogenetic characterization of the yak (Bos grunniens) and comparison with cattle (Bos taurus)

2009
The domestic yak (Bos grunniens) belongs to the family Bovidae and is one of the most important species for the economy of the Asian high lands. Recently, the interest for this species increased also in European countries, mainly because of its meat and milk characteristics.

Genetic variation in the β-lactoglobulin of Chinese yak (Bos grunniens)

Journal of Genetics, 2012
Yak (Bos grunniens) is distributed in the area of Central Asian highlands, it thrives in conditions of extreme harshness with severely cold winters, short growing seasons for herbage and no absolutely frost-free periods (Wiener et al. 2003). The total population of yak is estimated to be 14 million, about 90% of the domestic yaks are found on the ...

Reproduction in female yaks (Bos grunniens) and opportunities for improvement

Theriogenology, 2003
This paper reviews seasonal breeding, puberty, postpartum anestrus, embryonic loss and calf survival and their constraints in female yaks. Methods for improving fertility in postpartum yak cows are also considered. Yaks are seasonal breeders with mating and conception restricted in the warm season.

Skeletal muscle myosins from the yak (Bos grunniens), cattle (Bos taurus) and their hybrids

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1983
The skeletal muscle myosins of the yak (Bos grunniens), of cattle (Bos taurus) and of their first and second filial generation hybrids have been studied by ATPase measurements, fluorescence spectroscopy, near-ultraviolet circular dichroism and peptide mapping on polyacrylamide gels.

Parasitic infections of Indian yak Bos (poephagus) grunniens—an overview

Veterinary Parasitology, 1994
For centuries, the yak and its hybrids with domestic cows (dzomo/dzo) have been contributing to the socio-economic status of their owners in desolate regions of the Greater Himalayas. Studies on the prevalence of parasitic diseases in these animals were undertaken in Ladakh (Jammu and Kashmir), Sikkim and villages near the Indo-Nepal border of Uttar ...
