Abstract
The present study was carried out under farm conditions to compare the effects of cage and slat floor rearing systems on the growth performance, livability, uniformity, and welfare of Cobb 430 female broiler breeders during their growing phase (9–22 weeks). A total of 2,400 pullets were allocated equally to the two housing systems, with performance indicators such as weekly body weight, feed efficiency, foot lesions, shank length, and breast muscle condition assessed. The results showed that the cage-reared birds consistently showed significantly higher body weights (3176.18 ± 1.73 g vs. 2974.66 ± 2.70 g in slats at 22 weeks) and marginally better livability (95.0% vs. 93.3%). Slat-reared birds exhibited superior breast muscle scores with more birds in grades A and B compared to cages, alongside a slightly greater average shank length (7.14 ± 0.07 cm vs. 7.09 ± 0.08 cm). Foot lesion scores were significantly higher in the slat system (1.58 ± 0.17) than in the cage system (1.13 ± 0.13), indicating increased foot health challenges on slats. These findings demonstrate the need to balance enhanced growth and survivability in cage systems with better muscle development and leg health in slat environments. Integrating benefits from both systems can optimise broiler breeder management for productivity and welfare.
