Abstrakt: This study aimed to assess the growth performance, carcass characteristics, and meat quality traits of broiler chickens raised on plastic-grid floors, traditional wood shavings, and wood shavings enriched with zeolite. The experimental design included the allocation of 504-day-old chicks to three different bedding materials, namely wood shavings, plastic-grid floors, and zeolite litter, each with four replications (42 birds per replicate). The chicks were individually weighed at birth and grouped according to their average body weights. An experiment involving 504 chicks was conducted, with each replicate consisting of 42 male chicks of similar body weight. At the end of the experiment, a total of 120 chickens were slaughtered with 10 chickens selected from each replicate for processing carcass and meat quality traits. The effects of different bedding materials on mortality (P = 0.812), body weight (P = 0.565), and body weight gain (P = 0.569) were not significant. The ANOVA test was conducted to compare the main effects of performance, carcass, and meat quality characteristics. The feed intake was significantly affected in the 2nd, and 3rd weeks (P = 0.001; 0.023); in addition, the feed conversion ratio was significant in the 2nd, 4th, and overall period (P = 0.003; P = 0.026; P = 0.038) by the bedding materials. The breast yield (P = 0.001), thigh yield (P = 0.028), and wing yield (P = 0.023) were significant. The type of bedding material used in broiler production significantly influenced the pH 24 (P = 0.030), L* (P = 0.037), a* (P = 0.000), and CL (P = 0.028). It was concluded that both a plastic-grid floor and zeolite supplementation to wood shaving litter did not significantly affect overall growth performance in broiler chickens. However, the plastic-grid floor showed superior effects on breast meat yield and quality characteristics, particularly reducing cooking loss, when compared to zeolite supplementation in wood shaving litter. The plastic-grid floor led to a slight increase in the feed conversion ratio. Consequently, adopting a plastic grid floor emerges as a viable alternative to traditional wood shavings in broiler farming.
