This guide is intended to assist teachers in conducting a farm management simulation that has been designed to help vocational agriculture students acquire competency in both crop and livestock farming. The introductory section includes an overview of the simulation, planning considerations and suggested grading criteria, and a suggested sequence for developing the farm management problem (including a discussion of student choices, recommendations concerning the use of reference materials, and possible changes that individual instructors can make in the simulation). The first unit consists of crop production data on the following: liming, corn, soybeans, small grains, forages, harvest management, seeding mixtures and rates, pasture, and suggested rates and dates of seeding important Ohio crops. The following livestock production data are included in unit II: nutrient composition of feed stuffs commonly fed to cattle and sheep; metabolizable energy, vitamin, and mineral contents of swine feeds; average nutrient composition of feeds commonly used in horse rations; guidelines in selecting rations for dairy cattle, beef cattle, sheep, swine, horses, and poultry; space requirements for livestock, poultry, and horses; and breeding recommendations. Unit III consists of equipment and supplies cost data, including building and equipment costs for livestock, equipment costs and custom hire rates, acre-hours for tillage implements and other equipment, costs of farm supplies, and marketing data. Fourteen transparency masters are included in the fourth unit. (MN)
