Nutritional value for growing turkeys of corn of light test weight

An experiment was conducted to determine the relationship between test weight of corn and growth, efficiency of feed utilization, nutrient retention, and carcass composition of young turkeys. The MEn values of corn were also measured. Two samples of corn differing substantially in test weight were f...

Description
Summary:An experiment was conducted to determine the relationship between test weight of corn and growth, efficiency of feed utilization, nutrient retention, and carcass composition of young turkeys. The MEn values of corn were also measured. Two samples of corn differing substantially in test weight were fed to male turkey poults (Nicholas Large White) from 1 to 20 d of age. The test weights of the light-weight corn and the normal-weight corn were 55 kg/hL (43 lb/bu) and 70 kg/hL (54 lb/bu), respectively. The light-weight corn was lower in crude protein concentration (6.63%) than the normal-weight corn (8.53%). The determined MEn of the corn samples did not differ (3.22 vs 3.25 kcal/g). The light-weight corn diet had modest adverse effects on growth and feed efficiency of poults during the 1 to 7 d after hatching. Poult carcass composition and retention of nitrogen and energy were not affected by the test weight of corn
