EFSA scientific opinion that after the sorrows of the flesh de l'Espresso, will further pain to farmers, particularly pollicoltori. Supports EFSA considers that the welfare animal, in this case chickens for meat, that is, those chickens bred to be processed in the legs and wings, and Thigh several pieces, there are several reasons for concern. EFSA bring attention to the rapid growth, the result of intensive farming in which animals are subjected:
For broilers the main concerns in terms of being identified and associated to genetic selection were represented by disorders involving skeletal problems such as lameness, contact dermatitis, anatomical irregularities and sudden death syndrome. These problems are mainly related to rapid growth rates and resulting in poor welfare. The experts note the differences between countries, regions and different farming systems.
EFSA acknowledges that due to genetic selection has increased in broilers, the growth rate of four times, but this does not always coincide with the welfare of chickens. What to do? Simply put, says EFSA in genetically selected chickens should be taken into account not only the volume growth, but also the environment in which they live and do not necessarily force growth:
for example, to hot climates should be selected birds that grow Slowly, as the fast-growing broiler chickens are susceptible to heat stress. In addition, the genetic selection of poultry, it would be desirable to give high priority to reducing the number of lame birds and the reduction of contact dermatitis. These are important welfare problems, involving genetic predisposition and environmental conditions.
The situation is almost similar to breeding hens. EFSA writes:
For breeding animals, experts identify five main risk factors with impact on the welfare associated with management or genetic selection. The management factors are barren environment, animal density, dietary restrictions and limited sources of light, the genetic factor is the rapid growth rate. There are also concerns for the welfare arising from the interaction tra genetica e ambiente.
