The effects of choice feeding with whole wheat continuous, intermittent and with limestone on performance, egg quality parameters and profitability in laying hens

This study was conducted to investigate the effects of using whole wheat in choice feeding on performance, egg quality, and income laying hens. In study, a total 160-Hyline W-80 white commercial hens aged 28 weeks were divided into four treatment groups fed for 84 days. The as follows: 1) Control (C, standard hen feed), 2) C feed+choice continuously with separate cup (CW), 3) feed+weekly intermittent (WW), 4) continuous wheat+limestone together (WL). Choice by methods (continuous, weekly intermittent, limestone) caused significant decrease live weight change (P<0.01), increased feed consumption, conversion ratio compared control group (P<0.05). Total yield not affected (P>0.05). eggshell weight, thickness, shell per unit area, yolk color (P<0.01). However, it did significantly affect ratio, surface albumen height, Haugh values eggs Also, production costs, sales income, net profit similar all conclusion, performance economic parameters negatively; however, reductions some quality values.
