Show Feed Pigs Irradiated Yeast for Quick Gains Vitamin D Feeding in Winter Is Profitable The winter feeding of irradiated yeast to pigs should become a "must," following experimental work conducted at the University of Wisconsin. It was found that pigs that were fed four ounces of irradiated irradi-ated yeast in each ton of feed, and had access to cow manure, outdistanced out-distanced all others. The yeast-fed pigs made average daily gains of 1.51 pounds per head and required only 375 pounds of feed to produce each 100 pounds of pork. The pigs used in the investigation ! were allowed to run outdoors, indicating in-dicating that winter sunlight is not always sufficient to prevent vitamin D deficiency. Despite the high price of irradiated ir-radiated yeast, the feeding of only four ounces to a ton of feed, makes it very economical to use. Recent investigations indicate that rapid bringing to maturity of from 200 to 240 pounds will prove the most profitable weight under present conditions. Type of pigs arriving ar-riving on the market would indicate that there is considerable room for breed improvement. Produce houses " L report that too many rangy pigs are still being bred. Well managed pigs should produce a net profit of at least 86 cents per hundredweight, after all overhead, labor, food profit and other items are considered. Irradiated Ir-radiated yeast should increase this margin of profit considerably. |
