ABSTRACT

The Dairy Cattle Feeding Formulation System was developed to formulate feeding guidelines for meeting standards for lactating dairy cows. Difficulty of data entry because of complex file creation and manipulation was the major reason this program was not adopted widely in Virginia. As a result few rations were formulated by this program by extension personnel. A modified version of the original program has been created to simplify data entry and running the program. This program is accessed on the Computerized Management Network by the names DAIR3 or DAIR3S. The DAIR3 is a prompted version that leads the user through input. The DAIR3S is a semi-prompted version that removes most of the time-consuming prompting. Both versions correspond to the format on a printed input form. A file is created with cow production data, feeds available, feed prices, and changes to feed nutrient concentrations. This file will be retained on the computer until purged or written over and can be edited for corrections or update prices and analyses. This revised program has met with success because it eliminates the tedious time-consuming manipulation required to create and edit files and allows data entry in a step-by-step straight approach.
