Introduction forage production, defined in chapter 1 as the integrated end-product of conversion of solar energy into plant biomass, is the foundation of range animal production systems because plant biomass is of limited caloric value to man as a primary consumer, the value of this renewable resource is in the production of secondary and tertiary products through grazing animals.

In this assignment the author will produce a report that discusses nutritional and energy requirements, comparing and contrasting similarities and differences between the two groups for each nutrient and for energy. The required dietary energy concentration is a function of the energy requirement and the feed intake rate calculated requirements for dietary energy concentration typically are very high in early lactation because the rate of milk production is high relative to the feed intake rate. Daily intake levels the reference values used for the daily intake guide are based on those provided in the australia new zealand food standards code (fsc)the fsc has outlined the composition and labelling requirements for food.
