ABSTRACT
This study seeks to analyze the effects of different housing types and feed formulations on broiler chicken carcass weight. The experiment was conducted in a trial facility in Molalahu Village, Pulubala District, Gorontalo Regency, for 45 consecutive days between February and March 2025. A total of 192 two-week-old broiler chickens, including both males and females, were used as experimental animals. The study employed a completely randomized design (CRD) in a 2×6 factorial arrangement with four replications. The first factor was housing type, consisting of litter housing (A1) and slat housing (A2), while the second factor was feed combination with substitution of corn leaf meal and seaweed meal (B0–B5). The data were analyzed using analysis of variance (ANOVA), and significant effects were further examined using Duncan’s Multiple Range Test. The results indicated that housing type did not have a significant effect (P>0.05) on broiler carcass weight, whereas feed type had a highly significant effect (P<0.01). The control treatment (B0) produced the highest carcass weight (1,218.04 g), whereas treatments with higher proportions of corn leaf meal and seaweed meal (B3 and B4) resulted in the lowest carcass weights. The reduction in carcass weight at certain feed levels was suspected to be caused by anti-nutritional compounds, such as saponins, flavonoids, and phlorotannins, which inhibit protein absorption and muscle tissue formation. No significant interaction was observed between housing and feed factors on carcass weight (P>0.05). These findings suggest that feed is the dominant factor influencing carcass weight, while housing type can be adjusted according to environmental conditions.
