Effect of Corn Fiber Feed on Performance and Apparent Digestibility of Nutrients in Egg-laying Hens
For investigating the effect of corn fiber feed on production performance in laying hens, in this experiment,500 240-days-old laying hens were randomly allotted to 5 treatments > with each treatment represented by 5 replicates of 20 birds each. I to V groups experiment diets used 0,0. 92%, 1. 84% ,2. 76% and 3. 68%. Pre-feeding period was 7 days and the experiment lasted 60 days. The results indicated: ① Compared with the control group, there were no significant effect on the egg production rates, average egg weight, day-egg yields ,feed conversion ratio and broken (soft) eggshell rates. V group decreased the day-feed intake by 5. 48% significantly than the control group(P<0. 05). IV group decreased the mortality significantly by 87. 5% compared with the control group(P<0. 05). ② The apparent digestibility of CP of II group was lower than the control group(P<0. 05) .others were higher than the control group(P<0. 05). All the experiment groups were higher than . The control group in the index of Ca, II , III and IV experiment groups were effective. The index of P were higher than the control group(P<0. 05). ③ Every group increased the economic efficiency.
