Abstract: Compared with floorrearing(FR) and slatrearing(SR) broiler technical crafts, cagerearing(CR) has its own advantages as follows: 1) Feeding density are doubled, thus less land is needed. 2) Higher growing performance and better feed convertion rate is available. For 1 kg liveweight gain, 160 g less feed is consumed. 3) Leg diseases occations are lower than SR, but similar with FR. 4) More qualified birds are produced than SR and FR. 5) 0.8 yuan and 0.56 yuan more margin per bird is obtained than FR and SR respectively.
