Browse Selection by Goats in Grassland Ecosystems

Abstract

This chapter explores the browse selection behavior of goats within grassland ecosystems, underscoring their role as adaptive mixed feeders. Unlike strict grazers, goats exhibit a strong preference for browsing shrubs, forbs, and tree foliage, particularly during dry seasons when herbaceous forage is limited. Their dietary choices are influenced by plant palatability, nutritional value, seasonal availability, and the presence of physical and chemical defenses. Through selective feeding, goats can shape vegetation dynamics, controlling woody plant encroachment, enhancing grass regrowth, and influencing species composition. However, unmanaged browsing may lead to overutilization and land degradation. Understanding the ecological and nutritional drivers of goat browse selection is essential for sustainable rangeland management and optimizing livestock productivity in grassland ecosystems.
