Carcass, cut-up and giblets yield in sexed broilers maintained under floor and cage and their mutual transfer system

The aim of the present study was to compare different broiler rearing systems for carcass cut-up yield in sexed broilers. In the present study, 96 sexed broilers grown on 4 rearing systems (Floor, Cage, floor-cage and cage-floor) were used to study carcass, cut up, and giblets yield (%). The birds were arranged according to Completely Randomized Design and the data were analyzed using ANOVA technique in factorial arrangement. The means were compared using Duncan’s Multiple Range (DMR) test. Results showed significantly higher neck (%), drumstick (%), tender loin fillets (%), and wings (%) in birds kept on floor. Whereas, ribs and back (%) was found to be better in birds kept entirely in cages and in those shifted to cages after 21 days. The dressing (%) was found to be better only in floor reared females than males. However, giblets (%) and breast meat (%) were neither affected by rearing system nor by sexes. Hence the present study concludes that floor rearing system have better cut up yield for most of the organs.
