“…INTRODUCTION: Manganese (Mn) is an essential trace element for livestock, but little is known about the optimal Mn source and level for yak. METHODS: To improve yak’s feeding standards, a 48-h in vitro study was designed to examine the effect of supplementary Mn sources including Mn sulfate (MnSO(4)), Mn chloride (MnCl(2)), and Mn methionine (Met-Mn) at five Mn levels, namely 35 mg/kg, 40 mg/kg, 50 mg/kg, 60 mg/kg, and 70 mg/kg dry matter (includes Mn in substrates), on yak’s rumen fermentation. …”

“…AIM: To evaluate different thawing temperatures and duration on the post-thaw semen quality of Indian yaks bulls. MATERIALS AND METHODS: Semen ejaculates from four different yak bulls were collected using artificial vagina method and extended with tris extender containing 6.4% glycerol at 35°C, cooled gradually from 35°C to 5°C at 1°C/3 min and equilibrated at 4-5°C for 4 h and frozen in French mini straws using a programmable bio-freezer and finally stored in liquid nitrogen. …”
