BROILER UTILIZATION OF DIETS FORMULATED WITH HIGH OIL CORN AND ENERGYFROM FAT

A variety of corn having higher oil content (5.7%) than the common yel low dent corn (3.8%) was introduced experimentally in Brazil. Several questions about the nutritional characteristics of this newly develope d corn arose from poultry nutritionists, especially regarding its ener gy utilization by broilers. This study attempted to compare the high o il corn (HOC) with the yellow dent corn (YDC) commonly used in broiler feeds in Brazil, Broiler field performance was evaluated with two gro ups of broilers fed diets containing HOC or YDC and high or low energy levels from 1 to 21 or from 2 to 42 days, Dry matter digestibility (D MD), ether extract digestibility (EED), and AME(n) were also determine d with the two types of corn, Similar values of DMD and EED were found for both tyes of corn, but AME(n) was higher for HOC (3478 kcal/kg) t han for YDC (3280 kcal/kg). Results. suggest a better utilization of Y DC than HOC with young chicks when supplemental oil is added.
