Abstract

Milo, raw and heated soybean meal were irradiated with 5 Mrad and 10 Mrad, and fed to chicks ad libitum for three weeks. The diets contained 55% irradiated milo or 50% irradiated raw and heated soybean meal. The remaining 45% or 50% was a non-irradiated nutritionally adequate semi synthetic ration. Comparable non-irradiated feed ingredients were fed as control. Observations were made on growth, feed intake, metabolizable energy value of the diet, digestibility of protein and pancreas weight.<br>The following results were obtained:<br>1. Marked increase in feed intake was observed in irradiated milo diet. The metabolizable energy value of irradiated milo (5 and 10 Mrad) was significantly reduced.<br>2. Marked growth retardation and reduction of feed efficiency of heated soybean diet was observed by 10 Mrad.<br>3. Raw soybean diet showed significantly poorer growth than heated ones. However, chick growth, feed efficiency, protein digestibility and metabolizable energy of soybean diet were improved by 10 Mrad.<br>4. The activity of trypsin inhibitor and pancreatic hypertrophy of chicks fed the raw soybean diet appeared to be reduced in response to the radiation dose.<br>5. No gross symptoms of toxicity due to irradiated feed ingredients were found in any of the chicks.
