To meet perceived consumer demand and increase producers’ profit margins, the goal in turkey farming became the production of the maximum amount of breast meat at the lowest possible cost. As a result of selection for this single trait, 70% of the weight of mass market turkeys is in their breast.[2] Consequently, the birds are so heavy that they are completely incapable of reproducing without artificial insemination, and they reach such extreme weights so quickly their overall development fails to keep pace with their rapidly accruing muscle mass, resulting in severe immune system, cardiac, respiratory and leg problems.[1]
