The effects of shade and hormone implant on fattening yearling heifers

Abstract

Fifty head of Hereford heifers averaging 607 pounds per head were used in the 1959. They were placed in five lots, 10 head per lot on the basis of live weight and previous treatment. The heifers were on test from May 14, 1959, to October 1, 1959 (140 days). At the beginning of the experiment the heifers were consuming 5 pounds of sorghum grain, 1 pound of soybean meal, and 5 pounds of alfalfa per head daily. They were rapidly brought to a daily ration composed of all the sorghum grain they would consume, 1 pound of soybean meal, and 5 pounds of alfalfa hay. At the termination of the test, the heifers were sold on the central market at St. Joseph, Mo.
