Evaluation of Physical Structure. 1. Grass Silage

Journal of Dairy Science, 1993
Abstract Physical structure of 19 grass silages was investigated by measuring chewing activity with a group of eight cows for 4 d. Eating, ruminating, and total chewing indexes varied considerably among cows. Silages were made from perennial ryegrass different in growth stage at harvest, chopping lengths, and preservation methods. Eating index varied

220 Evaluation of Forage Quality of Crested Wheat Grass

Journal of Animal Science, 2022
Abstract An experiment evaluated forage value of crested wheat grass (CWG) harvested from Western Nebraska over a 2-year period (2019-2020). Two large pastures, comprised of 95% CWG, were divided into 13 paddocks (34.4 ha, 3 paddocks and 42.5 ha, 10 paddocks). Within each pasture, 2 paddocks were assigned at random for sampling.
