Although Nutrient Requirement tables and Feed Composition tables (as supplied in Appendix A) provide volumes of information that is useful in feed formulation, it should be understood that the farm manager has a more comprehensive set of feed management “tools” at his/her disposal. These “tools” can assist the farmer on a daily basis to improve the feed management on the farm.
Remembering that feed is the most expensive input in a livestock production operation, it makes sense that different methods should be employed to obtain the most benefit out of feeds at the lowest cost.
