Résumé anglais
Although the poultry industry has developed into an intensive management system over the past several decades, current trends are moving towards extensive systems with decreased hen stocking density. However, there is limited information on the resource demands of such systems, particularly with regards to labor requirements. Labor-hour commitment per hen-housed and hen-day were evaluated for 4 different environments: range (R), cage-free (CF), modified cage (MC), and conventional cage (CC). Within each system, 3 strains of brown egg layers were examined to determine whether production system influenced labor-hours. Data collection began at 33wk of age and continued until 89wk in all environments. Range systems demonstrated the highest labor-hour requirement for both the hen-housed and hen-day measurements, particularly during the summer months when pasture management within the paddocks was time consuming. Conventional and modified cage systems required the least time commitment with cage-free serving as an intermediate. Cage-free labor-hours increased towards the end of the cycle as maintaining litter quality within the house became more demanding. The cost of labor-hours was not offset by the price per dozen eggs produced and the difference was greater in the extensive systems. This study supports previous findings that extensive layer production systems require greater labor-hours and provides an economic perspective to the increased time commitment.
