Nutrition, Feeding, and Calves: Different Techniques to Study Rumen Fermentation Characteristics Of Maturing Grass and Grass Silage

摘要

Grass samples were harvested during the 1993 growing season after a precut on April 27, 1993 and were stored frozen or left to ensile in 30-L buckets. Effects on chemical composition and fermentation ki- Netics of the maturation of the grass and of ensiling Were investigated. Chemical composition and fermen- Tation kinetics were determined using the gas produc- Tion technique, in vitro techniques, and the nylon bag Technique. Two silage samples were also investigated In vivo.
