Abstract

Foot pad dermatitis (FPD) represents a widespread problem and constitutes a welfare issue in broiler production. This study examined the effects of genotype, (fast-, medium- and slow-growing broilers), production system (indoor and outdoor access) and sex on the incidence of FPD. A total of 2,240 1-day-old mixed male and female chicks were reared to 12 weeks of age in an 8x2 factorial design. For each of 8 genotypes, chicks were randomly allocated to 1 of 2 production systems with 2 replicates, each comprised of 70 birds per pen. A four-stage feeding program was implemented consisting of broiler starter, layer chick starter, layer chicken grower and layer chicken developer feed, with all feed and water were offered ad libitum. A continuous lighting regimen (23 hours/day) was used for the first 2 weeks, and a daily lighting regimen (14 hours/day) was used for the remainder of the study. At 8, 9, 10, 11 and 12 weeks of age, 6 males and 6 females per genotype were slaughtered, and FPD scores were calculated for left feet.
