[Comparisons of endocrine hormones levels between Tibetan antelope and Tibetan sheep].

Sheng li xue bao : [Acta physiologica Sinica], 2013
The Tibetan antelope, a prototype mammal, has developed a unique adaptation to extreme high altitude-associated hypoxia. To investigate the role of the endocrine system in adaptation to high altitude in the Tibetan antelope, comparisons of endocrine hormones levels between Tibetan antelope (n = 9) and Tibetan sheep (n = 10) were performed.

Seroprevalence of Toxoplasma gondii Infection in Tibetan Sheep in Northwestern China

Journal of Parasitology, 2010
The seroprevalence of Toxoplasma gondii infection in Tibetan sheep was surveyed in Qinghai Province, northwestern China, in May and June 2010. In total, 580 serum samples was collected from 6 counties, and antibodies to T. gondii were detected by indirect hemagglutination (IHA) test. Antibodies to T.

Effects of different Lys/Met ratios on the antioxidant capacity, tissue morphology, and fatty acid composition of subcutaneous fat in Tibetan sheep on low-protein diets: a lipidomic analysis

Frontiers in Veterinary Science
Introduction This study employed lipidomics to investigate the effects of varying lysine (Lys)- to-methionine (Met) ratios on the antioxidant capacity, tissue morphology, and fatty acid composition of subcutaneous fat in Tibetan sheep fed a low-protein ...

Effects of yak and Tibetan sheep trampling on soil properties in the northeastern Qinghai-Tibetan Plateau

Applied Soil Ecology, 2019
Abstract Grassland soil is affected by trampling, ingestion and excretion by herbivores, of which the effects of trampling are most pronounced and intense. However, the mechanism of livestock trampling on grassland soil remains uncertain. The objective was to ascertain the differential effects of trampling by yaks and Tibetan sheep on grassland at ...

Grazing Promotes Decomposition of Tibetan Sheep Dung in Alpine Meadow Through Decoupling Climate

Land Degradation & Development
Dung decomposition plays a pivotal role in the cycling of carbon (C), nitrogen (N), and phosphorus (P). However, the combined effects of grazing system and grazing intensity on dung decomposition remain unclear.

Contribution of nitric oxide to adaptation of tibetan sheep to high altitude

Respiratory Physiology & Neurobiology, 2004
We examined the effects of endogenous nitric oxide synthase (NOS) inhibition on pulmonary hemodynamics in awake sheep living at low and high altitudes to evaluate the role of NO in adaptation to an hypoxic environment. Unanaesthetized male sheep in three places--Matsumoto, Japan (680 m above sea level), Xing, China (2300 m) and Maxin, China (3750 m ...

Effects of Phytosterol Licking Blocks on Growth Performance, Serum Biochemical Parameters and Rumen Fermentation in Tibetan Sheep.

Journal of animal physiology and animal nutrition
Phytosterols are plant-derived natural compounds which resemble in structure with cholesterol. It has been demonstrated that phytosterols significantly affect growth regulation and antioxidant capacity in poultry and pigs; however, their role in ...

Distribution of Cryptosporidium species in Tibetan sheep and yaks in Qinghai, China

Veterinary Parasitology, 2016
Few data are available on the distribution of Cryptosporidium species in Tibetan sheep and yaks, which are free-range animals living in a cold, low oxygen, and high ultraviolet radiation habitat. In this study, 904 fecal specimens were collected from 350 Tibetan sheep and 554 yaks in six counties. Cryptosporidium spp.

First Report of Coxiella burnetii Seroprevalence in Tibetan Sheep in China

Vector-Borne and Zoonotic Diseases, 2015
Query (Q) fever is a vector-borne zoonosis caused by the obligate intracellular pathogen Coxiella burnetii. Animals, including dogs, cats, cattle, and sheep, can be infected by C. burnetii. However, little information is available about C. burnetii infection in Tibetan sheep in China. Antibodies against C.
