Effects of Bedding Materials on Growth Performance, Footpad Dermatitis, Blood Parameters, and Economic Outcomes in Broiler Chickens

A 42-day trial compared rice hulls and rubberwood shavings as broiler litter applied at an equal rate (7.5 kg/m2) in a house equipped with an evaporative cooling system. A total of 552-day-old male Ross 308 broiler chicks were randomly assigned to two treatments, with 12 replicate pens per treatment and 23 birds per pen. Body weight, feed intake, and feed conversion ratio (FCR) were assessed during the starter (0–14 d), grower (15–35 d), and finisher (36–42 d) phases. Footpad dermatitis (FPD), litter moisture, and complete blood counts were evaluated on days 14, 35, and 42, whereas infectious bronchitis (IB) antibody titers were measured on days 14 and 35. Rubberwood shavings increased body weight and feed intake during the grower and finisher phases and improved FCR during days 36–42 (p < 0.01). The FPD scores were lower with rubberwood shavings on days 35 and 42 (p < 0.05), although litter moisture was numerically higher on day 42. Hematological responses were transient, and IB antibody titers were unaffected. Economic analysis showed higher net profit (p < 0.01) and marginally higher return on investment in broilers reared on rubberwood shavings, with the economic advantage becoming more evident after footpad downgrade loss was considered.
