ABSTRACT 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 poultry pigs; however, their role ruminants remains unclear. This study aimed to investigate the effects of phytosterol lick blocks on performance, serum biochemical rumen fermentation parameters Tibetan sheep. Fifteen 5‐month‐old sheep (29.16 ± 1.51 kg) were randomly assigned three...
Abstract The aim of this study was to investigate the effects ensiled agricultural byproducts from Qinghai-Tibet plateau on growth performance, rumen microbiota, ruminal epithelium morphology, and nutrient transport-related gene expression in Tibetan sheep. Fourteen male sheep were randomly assigned one two diets: an untreated diet (without silage inoculum, CON, n = 7) or (with ESD, 7). total experimental period lasted for 84 d, including early 14 d as adaption remaining 70 data collection....
Introduction Manganese (Mn) is an essential trace element for livestock, but little known about the optimal Mn source and level yak. Methods To improve yak’s feeding standards, a 48-h in vitro study was designed to examine effect of supplementary sources including sulfate (MnSO 4 ), chloride (MnCl 2 methionine (Met-Mn) at five levels, namely 35 mg/kg, 40 50 60 70 mg/kg dry matter (includes substrates), on rumen fermentation. Results showed that Met-Mn groups higher acetate ( p <...
Copper (Cu) is essential for the health of livestock, however, optimal source and level dietary Cu yaks are uncertain. To fill this important gap, we designed an in vitro study to examine effects three sources, namely methionine (Met-Cu), chloride (CuCl2) tribasic (TBCC), at five levels, 5, 10, 15, 20 25 mg/kg DM (includes substrate), on rumen fermentation yaks. In dry matter degradability (IVDMD) amylase activity were greater (p < 0.05) with added Met-Cu than other two ammonia nitrogen...
Copper, manganese, and iodine are part of a yak’s required trace elements. However, knowledge about their dietary requirements is scarce. Therefore, an experiment was conducted to evaluate rumen fermentation, blood parameters, growth performance screen out the optimum levels elements in yaks’ diet. Here, 18 three-year-old castrated yaks were randomly divided into four groups, which fed with diets containing basal (CON: 4.40, 33.82, 0 mg/kg) low-level (LL: 10.00, 40.00, 0.30 mg/kg),...
