VI. Estimating Feed Requirements of Ruminant Livestock in Tropical and Sub-Tropical Regions.

Precise information is generally lacking for a specific region, but general criteria may be formulated from fragmentary data in a few instances, supplemented with more comprehensive evaluations from rangeland livestock in the dry temperate zone regions.

For convenience, guidelines as to nutrient requirements of ruminant livestock (particularly cattle, sheep and goats), may be expressed in daily and yearly feed requirements expressed in total dry weight of forages consumed, and in the animal needs for total digestible nutrients (TDN), and crude protein.
