State the three sources of water for use by an animal.

a) Roughages and concentrates are two main categories of animal feedstuffs, differing primarily in their fiber content and nutrient density. • Roughages are feedstuffs that are high in fiber (crude fiber content typically above 18%) and relatively low in digestible energy and protein. They are bulky and provide satiety, promoting gut health. Examples include hay, silage, and fresh pasture grass. • Concentrates are feedstuffs that are low in fiber (crude fiber content typically below 18%) and high in digestible energy or protein. They are dense in nutrients and are used to supplement the diet to meet specific nutritional requirements for growth, production, or reproduction. Examples include cereal grains (like maize), oilseed meals (like fish meal), and molasses.
