Under traditional management on the Qinghai-Tibetan Plateau, yaks () graze only natural pasture without supplements and are forced to cope with sparse forage of low N content, especially in winter. In contrast, indigenous Tibetan yellow cattle require during cold season. We hypothesized that, response harsh conditions, intakes better than cattle. To test this hypothesis, a study whole-body retention urea kinetics was conducted 2 concurrent 4 × Latin squares, 1 square using Four isocaloric...
Rumen studies have focused almost exclusively on livestock species under strictly regimented diets. This means that the ruminal condition of free-living and free-feeding wildlife remains practically unstudied. Urea nitrogen salvaging, a process by which urea is passed into rumen, to both provide valuable source for bacterial growth buffer potentially harmful acidic effects short chain fatty acids, has remained unexplored in wild ruminants, such as deer. UT-B2 transporters are key proteins...
Aquaporins (AQPs) are a large family of integral membrane proteins that facilitate the transport water through biomembranes. AQP1, one 13 AQPs identified in mammals, is distributed various tissues and organs, plays an important role body homeostasis. The objectives present study were to identify expression aquaporin-1 (AQP1) kidney, rumen parotid gland yaks, quantify whether protein abundance AQP1 species specific between yak (Bos grunniens) indigenous cattle taurus). Three 3-year-old...
Urea nitrogen secreted from blood to rumen is a crucial factor shaping the symbiotic relationship between host ruminants and their microbial populations. Passage of urea across epithelia facilitated by transporter B (UT-B), but long-term regulation these proteins remains unclear. As ruminal function develops over period months, developing an excellent model with which investigate this regulation. Using epithelium samples calves birth 96 d age, study performed immunolocalization studies...
The urea nitrogen salvaging process (UNS) supports the symbiotic relationship between ruminants and their gastrointestinal microbiome by both supplying buffering bacterially-derived short chain fatty acids (SCFAs). Studying such physiological processes via investigation of rumen papillae morphology functioning, as well western blotting to detect transporters, allows researchers test hypotheses linking physiology ecology. goal this innovative approach is indicate way forward for future...
The rumen ecosystem represents a classic example of symbiotic relationship between host animals and microbial populations. Urea nitrogen secreted from the blood to is crucial factor shaping this relationship. transport urea across epithelium facilitated by proteins namely transporter B (UT‐B) possibly aquaporin‐3 (AQP3). However, how ruminants regulate availability microbes through these remain unclear. Given that calves are stage at which colonization begins, developing an excellent model...
