Principles of supplementary feeding in sheep-grazing systems.

Abstract

The major reasons and practical considerations for supplementary feeding of sheep maintained under grazing systems are presented. The relation between the intake of herbage and supplements, including the concepts of substitution and complementation, are discussed. The chapter elaborates on the nutritive value and types of supplementary feed, which come in the form of energy/high-carbohydrate and protein supplements, conserved forages, and forage crops.
