Abstract

ABSTRACT We assessed the effect of rumen fluid (RF) collection site (central vs. ventral), seaweed (with or without Asparagopsis taxiformis) and their interaction on in vitro total gas and methane yield, and fermentation parameters. Rumen fluid was collected via esophageal tubing from six cows, controlling sampling locations manually through the rumen cannula. Linear mixed-effect model analysis revealed no interactions between rumen fluid collection site and seaweed. Seaweed reduced (P < 0.01) total gas and methane yield (mL/g DM) by 10% and 93%, respectively. Collection site had no effect on total gas yield, but methane yield was slightly lower (P = 0.03) with central than ventral RF. Our pilot study is the first report on gas parameters for incubated rumen fluid from different collection sites, and the observed effect of collection site on CH4 yield provides further evidence for the importance of representative rumen sampling.

期刊介绍： Acta Agriculturæ Scandinavica, Section A – Animal Science publishes results of original research in animal science and their applications related to the following topics: -Animal breeding and genetics -Molecular genetics -Animal physiology and reproduction -Nutrition and feeding -Animal behaviour and welfare -General animal husbandry and systems of production, including economic and technical aspects -Hygiene and quality of animal products In addition to original articles, covering basic as well as applied subjects, the journal features review articles and short communications. Acta Agriculturæ Scandinavica, Section A – Animal Science forms part of a trilogy of titles published on behalf of the Nordic Association of Agricultural Scientists (NJF). The series also includes Section B - Soil & Plant Science and the recently launched Section C - Food Economics . Acta Agriculturae Scandinavica A, B and C are available to purchase as a combined subscription. This provides access to all three journals in the series, and is available to institutional subscribers only. For full pricing information, please view the Taylor & Francis Journals Price List here.
