Effects of Asparagopsis taxiformis on enteric methane emission, rumen fermentation and lactational performance of (Norwegian Red) dairy cows
Eikanger, Katrine Sømliøy (Master thesis, 2022)Ruminants with their rumen microbial fermentation contribute to greenhouse gas emissions when producing enteric methane. Feed supplements able to inhibit the formation of methane and thereby reduce the amount of methane ... -
Exploring current practices and the potentials of Nanopore sequencing in metagenomics
