Factors Affecting Nutritional Value of Feedstuffs
نویسندگان
چکیده
For ruminants, the microbial population existing in the rumen breaks down feed ingredients offered to the animal. This population must be healthy and viable to permit maximum utilization of feed ingredients. Because ruminants evolved mainly as forage feeders, factors that disrupt population of cellulolytic microorganisms will result in reduced utilization of nutrients -primarily, energy and protein, but also reduced production of vitamins and utilization of minerals. Factors that affect nutritional value of feedstuffs are discussed below.

There is a tendency to consider forages largely in terms of their energy value or TDN. However, the feeding value of forage is actually a more complex function of its nutrient composition, chemical-physical characteristics of its fiber, acceptability (palatability), and associative interactions it might have with other dietary ingredients. Because forages are not usually cost-competitive with c...
