Two hundred and forty commercial female day-old broiler chicks were used to investigate the effects of high-fiber grains on the growth rate and various gut sizes. Four experimental diets were formulated to have similar energy and protein contents, with corn and sorghum as low-fiber2048 grains, and rye and hulled barley as high-fiber grains. Birds were housed randomly in 20 wire-floor cages. There were 5 replicates per treatment and 12 chicks per replicate (pen). At 3 wk of age, rye-fed broiler chicks grew at significantly lower rate than did the other birds. At 6 wk of age, the growth rates of birds fed rye and sorghum were significantly lower than those of birds fed barley and corn. The feed efficiency of the rye treatment at 6 wk of age was significantly poorer than those of corn and barley treatments, and that of the sorghum treatment was intermed
