Abstract

Livestock feeders operate on a narrow margin of profit. Their profit generally depends on rapid and efficient live weight gains rather than on a wide spread between buying and selling price of the animals. The need for efficient meat production has prompted agricultural scientists to develop and investigate a desperate array of compounds having growth stimulating properties and thereby aid the livestock feeder in improving rate and efficiency of gain. The market situation of inedible animal fats has changed dramatically in recent years. Lard and tallow are not currently used to the extent that they once were in the manufacturing of soap and explosives. Fat is a high-energy nutrient having approximately 2.25 times the number of calories as carbohydrates or proteins per unit of weight. Since animal fats have become relatively cheap and because they are such concentrated source of energy, their use as a concentrate replacement has been studied. The work reported here in was undertaken to study and compare the effects of diethylstilbestrol (implanted or supplied in the protein supplement).
