Red Clover Hays of Varying Phosphorous Content for Growing Beef Calves

Introduction: The Tennessee Valley Authority is vitally interested in the effect of phosphorous on crop yields and the nutritional value of these crops on livestock. They manufacture different phosphatic fertilizers and test them on farms and in laboratories. Financial assistance is given by the Tennessee Valley Authority to the Tennessee Experiment Station in this study of the feeding value of clover hays of varying phosphorous contents for growing beef calves. This experiment was originated to (1) study growth of calves fed rations differing only in the phosphorous content of the red clover hay; and (2) to study the availability to growing beef calves of the phosphorous in the red clover hays having a different phosphorous content.
