Association of BMPR-1B Gene 3’-UTR Region Polymorphism with Litter Size in Tibetan Sheep [PDF]

Kafkas Universitesi Veteriner Fakültesi Dergisi, 2021
Bone Morphogenetic Protein Receptor-1B (BMPR-1B) is considered as the primary gene in sheep for follicular development and litter size trait. It has been defined as the most major candidate gene for genetic markers of sheep reproductive performance.

Variations in HIF-1α Contributed to High Altitude Hypoxia Adaptation via Affected Oxygen Metabolism in Tibetan Sheep

Animals, 2021
The Tibetan sheep is an indigenous species of the Tibetan plateau and has been well adapted to high-altitude hypoxia. In comparison to lowland sheep breeds, the blood gas indicators have changed and the HIFs signaling pathway is activated in Tibetan ...

Evaluation of the recombinant egagb8/2 antigen for the diagnosis of cystic echinococcosis in tibetan sheep on the qinghai-tibetan plateau, china [PDF]

Kafkas Universitesi Veteriner Fakültesi Dergisi, 2021
The unique geographical and ecological conditions of the Qinghai-Tibetan Plateau (QTP) constitute the environmental conditions of the natural foci of cystic echinococcosis (CE). It is a rare and highly endemic area in the world.

Transcriptomic Study of Spermatogenesis in the Testis of Hu Sheep and Tibetan Sheep

Genes, 2022
Numerous genes involved in male reproduction regulate testis development and spermatogenesis. In this study, the testis tissue transcriptome was used to identify candidate genes and key pathways associated with fecundity in sheep. Histological analysis of testis tissue using hematoxylin–eosin (HE) routine staining was performed for two sheep breeds ...

Physiology and Proteomic Basis of Lung Adaptation to High-Altitude Hypoxia in Tibetan Sheep

Animals, 2022
The Tibetan sheep is an indigenous animal of the Tibetan plateau, and after a long period of adaptation have adapted to high-altitude hypoxia. Many physiological changes occur in Tibetan sheep as they adapt to high-altitude hypoxia, especially in the ...

Study on the Plateau Adaptive Synergistic Mechanism of Rumen Microbiome-Metabolome-Resistome in Tibetan Sheep. [PDF]

Microorganisms
Tibetan sheep are an important livestock breed adapted to the extreme environment of the Qinghai–Tibet Plateau (QTP). Their energy metabolism and environmental adaptability are highly dependent on the rumen microbiome.

The interaction between rumen microbiota and neurotransmitters plays an important role in the adaptation of phenological changes in Tibetan sheep. [PDF]

BMC Vet Res
The gut-brain axis is regarded as the “second brain” of the host. Gut microbiota and their metabolites affect intestinal homeostasis, function, and phenotype by regulating bidirectional communication between the gut and brain.
