A comparison of barley, corn and wheat as the grain in broiler starter rations Haazele, Felix M.
Abstract
Growth trials, a digestibility and N-retention trial were conducted using broiler chicks to compare the nutritional value of broiler starter rations based on barley, corn, wheat or combinations of two cereals.
When barley replaced wheat to a maximum level of 50% of the total diet with adjustments to keep diets iso-nitrogenous, feed consumption increased with increasing barley, weight gain fell when barley was used at levels beyond 30% of the diet and feed efficiency fell with increasing barley. However, differences in these parameters were not significant. Feed intakes were 1274, 1292, 1323, 1304, 1311 and 1308 g/bird, weight gains 806.25, 817.50, 826.00, 817.25, 802.75 and 797.50 g/bird and feed/gain ratios 1.58, 1.58, 1.60, 1.60, 1.63 and 1.64 for 0, 10, 20, 30, 40 and 50% barley diets respectively.
When corn replaced wheat to a maximum level of 48.6% of the total diet, feed intake significantly (P
