Effects of Insoluble Fiber on Growth Performance, Carcass Traits and Ileum Morphological Parameters on Broiler Chick Males

To determination the effects of insoluble raw fiber concentrate (IRFC) on performance, carcass and ileum morphologic traits, four dietary treatments containing 0, 0.25, 0.50 and 0.75% levels of IRFC with four replicates were fed to 240-days-old Lohmann chick males for 42 days. Weight gain significantly differed in grower (22-42 d) and total of experimental period (042 d) and the control group shows a lower weight gain than other groups. Feed conversion rate (FCR) for the control and 0.25% IRFC at the starter and control group for grower and overall of period was greater than other groups. IRFC at the rate of 0.50 and 0.75% produced significantly greater carcass and breast meat than the other groups. Significant differences were observed in intestine and abdominal fat. Use of 0.75% IRFC had lower intestine percentage as compare to other groups. Likewise control group had a higher abdominal fat than other groups, while thigh and liver had no significant differences. Crypt depth did not show differences at day 21 and 42. At day 21 control group had a lower height of villi than others, also control and 0.25% IRFC had a lower villi to crypt ratio (V/C) as compare to 0.50 and 0.75% groups. At day 42, all of IRFC groups had higher villi height and a high V/C ratio than control group. © 2010 Friends Science Publishers
