Journal ArticleDOI
Effects of essential oils on digestion, ruminal fermentation, rumen microbial populations, milk production, and milk composition in dairy cows fed alfalfa silage or corn silage.
TL;DR: Results from this study showed limited effects of MEO supplementation on nutrient utilization, ruminal fermentation, and milk performance when cows were fed diets containing either AS or CS as the sole forage source.
Journal ArticleDOI
Fatty acids in forages. I. Factors affecting concentrations
TL;DR: Forages represent a high proportion of ruminant diets they provide a significant quantity of fatty acids (FA), and effects of growth stage, fertilization, conservation method, growth period, species, and cultivar on forage FA were determined.
Journal ArticleDOI
Effects of addition of essential oils and monensin premix on digestion, ruminal fermentation, milk production, and milk composition in dairy cows.
TL;DR: Results from this study suggest that feeding EO and MO to lactating dairy cows had limited effects on digestion, ruminal fermentation characteristics, milk production, and milk composition.
Journal ArticleDOI
Lower Pregnancy Losses in Lactating Dairy Cows Fed a Diet Enriched in α-Linolenic Acid

TL;DR: In this article, the effects of a diet enriched in alpha-linolenic acid (ALA) would influence ovarian function, early embryo survival, conception rates, and pregnancy losses in lactating dairy cows.
Journal ArticleDOI
Milk production and composition, ovarian function, and prostaglandin secretion of dairy cows fed omega-3 fats.

TL;DR: The results suggest that the improvement in gestation rate that was observed when feeding increased levels of alpha-linolenic acid in earlier work may partly result from lower levels of production of the dienoic prostaglandin PGF2alpha.
