During the autumn-winter-spring season of 2016-2017, Center for Breeding Steppe Animals (Orenburg region) conducted coprological surveys herbivores. Identified contamination strongylata have yaks and camels at a low infestation intensity. These animals were not dehelmintizated in autumn period. By spring, strongylate intensity increased. The kiangs Przewalski’s horses kept here subjected to deh...

Currently, information available on the comprehensive changes in rumen bacteria and metabolites of yaks fed high-grain diets is limited. This study aimed to investigate effects diet feeding blood metabolites, microbiome, metabolomics by using 16S rDNA gene sequencing liquid chromatography–mass spectrometry (LC/MS). Here, fourteen healthy male (body weight, 249.61 ± 8.13 kg) were randomly assign...

Mitochondrial DNA (mtDNA) is widely used in various genetic studies of domesticated animals. Many applications require comprehensive knowledge about the phylogeny of mtDNA variants. Herein, we provide the most up-to-date mtDNA phylogeny (i.e. haplogroup tree or matrilineal genealogy) and a standardized hierarchical haplogroup nomenclature system for domesticated cattle, dogs, goats, horses, pig...

With assistance from lay volunteers and using a giant stove, Tibetan monks at Longen monastery in rural Qinghai province China prepare and serve meals for several hundred of their peers during the summer retreat. In the past, rugged geography and the isolation of this monastery above 13,000 feet gave reasons for the monks to eat local meat since other foodstuffs were unavailable in an area unab...

Six abomasums of yaks (Bos grunniens) were studied with gross dissection and histological methods. It was found that the mucosa of the yak abomasum was covered with simple columnar epithelium. There were lots of spiral folds (≥10) in the fundic glandular area. The developed membrane of lamina propria was occupied by high density glands. According to the morphological characteristics of the glan...

Abstract One of the most important achievements Tuvans in process adaptation to nomadic culture and extreme continental climate Central Asia was breeding various domestic animals adapted different ecological conditions region. The main wealth a nomad is livestock: horses, camels, cattle, sheep goats, yaks, reindeer. article analyses problems livestock theft Tuva from mid-nineteenth century curr...

Shiga toxin (Stx)-producing Escherichia coli (STEC) are recognized as important human pathogens of public health concern. Many animals are the sources of STEC. In this study we determined the occurrence and characteristics of the STEC in yaks (Bos grunniens) from the Qinghai-Tibetan plateau, China. A total of 728 yak fecal samples was collected from June to August, 2012 and was screened for the...
