Digestion Studies with Oat Silages Using a New Fecal Collection Technique

Abstract
Nine 8-month-old Holstein bulls were used to determine the apparent digestibility of oat silage made of oat forage harvested in the boot, earlymilk and soft-dough stages. Total fecal collections were made in 6-mil polyethylene bags described herein. The TDN content of the silages for boot, early-milk and soft-dough stages was 67.0, 60.9 and 54.1%, respectively. During the 14-day interval between the boot and soft-dough stages, TDN decreased 1.4% daily. Copyright © . .
