Ruminal Flora Studies in the Sheep IV. the Influence of Varying Dietary Levels of Protein and Starch Upon Digestibility, Nitrogen Retention, and the Free Microorganisms of the Rumen

Abstract
Data are presented from a replicated feeding trial with sheep, designed to determine the influence of varying dietary intakes of starch and protein upon digestibility, protein utilization, and the numbers and types of "free" bacteria in the rumen.
