Feed Value for Sheep of Cornstalks, Rice Straw and Barley Straw as Compared with Alfalfa

Abstract

The feed values of pelleted cornstalks, rice straw and barley straw fortified to equivalent N, P and S levels and unsupplemented pelleted alfalfa were compared in digestion trials with rumen fistulated sheep. Dry matter intake and digestibility, digestible energy, rumen fermentation, and ruminal VFA and microbial protein data indicated that the relative feed value of these rations was from highest to lowest, alfalfa, cornstalks, rice straw, and barley straw. The results indicate that fortified cornstalks and rice straw can be used as a part or all of the maintenance ration of sheep. Copyright © 1971. American Society of Animal Science .
