Eliminating Unwanted Day-Old Chicks

摘要

An evaluation of the 'Carbon dioxide (CO_2) method' with the 'Fast cutting-method' - better animal welfare versus improved efficiency. Hatcheries that produce chicks from table egg layer strains as well as those breeding hatcheries that produce parent stock, grandparents and great' grandparents face the problem of disposing of large numbers of 'unwanted' chicks. These are the male chicks from layer strains or the other sex from the male and female lines at GP and GGP levels.
