R.  aFurther studies concerning the effects of fats in sheep rations.  c1958  aIn growth and digestibility studies with sheep, it was found that the inclusion of 15% animal fat in a basal ration containing cottonseed hulls significantly reduced the digestibilities of dry matter and organic matter, and the weight gains. The addition of alfalfa ash, sodium bicarbonate, or potassium bicarbonate to the high fat ration did not improve weight gains; in fact, both bicarbonates tended to depress appetites and gains. In another experiment, it was shown that the addition of 10% corn oil reduced gains regardless of whether it was absorbed by the concentrate or roughage portion of the ration. Neither 10 nor 15% corn oil in the rations of sheep increased the accumulation of blood and urine ketone bodies. The addition of corn oil did not seem to affect diurnal ruminal pH values of sheep, whereas alfalfa ash and sodium bicarbonate tended to reduce the hydrogen-ion concentration. The addition of corn oil caused an accumulation of a frothy foam in the rumen. Some nutritional implications of these observations were discussed.  aSheep1 aSIRNY, R. J.1 aTILLMAN, A.
