Effects of feeding 3-nitrooxypropanol to lactating dairy cows on methane emissions, animal performance and rumen fermentation
DownloadFall 2014
Methane emissions from ruminants are of great concern as they contribute to greenhouse gasses emitted within the atmosphere. The objective of this research was to evaluate a novel biochemical compound, 3-nitrooxypropanol, on its ability to reduce methane emissions and its impact on animal...

Repeatability of anogenital distance in Holstein cattle and its association with embryo yield and quality
DownloadSpring 2021
Reproductive phenotypes that are easy to measure, have high genetic variation and heritability along with good repeatability are being explored for genetic selection of cows for improved fertility. In this regard, anogenital distance (AGD; the distance from the center of the anus to the base of...
