title: Response of Ross 308 and Hubbard broiler chickens to feed removal for different durations during the day.
abstract: The effects of feed removal for 6, 8, or 10 h during the day from 8 to 28 days of age followed by ad libitum feeding to market age on the growth performance of two strains of broiler chickens, Ross 308 and Hubbard, were studied over 7 weeks. Ross 308 was superior to Hubbard in weight gain and final body weight but consumed more feed and deposited more abdominal fat. Overall, daily feed removal reduced feed intake and improved feed efficiency in all feed-restricted birds, and the longer the period of feed removal the better the efficiency of utilization, but it had no significant effect on weight gain and market weight. It is suggested that for broiler production in the tropics, Ross 308 could be used on a 10-h daily feed removal program from 8 to 28 days of age.
