The aim of the present study was to evaluate the influence of neonatal feeding on zootechnical and economic aspects of the initial production of broiler chickens. A total of 320 Cobb-500 male chicks were used. After vaccination, the neonatal hydrating feed was added to the transport box. Four control groups were formed (A to D) with chicks 8, 24, 48 and 72 hours after hatching without neonatal feeding and four experimental groups were formed (E to H) with chicks lodged 8, 24, 48 and 72 hours after hatching with neonatal feeding. The hydrating supplement demonstrated dehydration of the chicks. Group E had an initial body weight gain of 1.88% associated with a shorter post-hatch lodging interval. At seven days of age, the chicks in Group F, which received neonatal feeding, were an average of 15.31 g above the expected weight. Based on yield rates at seven and 14 days, the average live chicken gross margin and average carcass gross margin were positive in birds that received neonatal nutrition. Neonatal supplementation offers a financial benefit by enhancing animal wellbeing and contributing to an increase production profit.
