Individual differences in welfare within broiler breeder flocks
Broiler chickens have been heavily selected for efficient meat production and are well known for their voracious appetites and rapid growth. However, this rapid growth comes with an increased risk of health problems, which presents problems especially for the parental generation: the broiler breeders. To slow their growth and alleviate cardiovascular, skeletal and fertility-related health problems these breeders live part of their lives under heavy feed-restriction regimes.
While feed-restriction keeps the birds physically healthier, it is bound to leave them feeling very hungry. My research project is about these hungry young breeders and their welfare. The initial questions of my research are about the differences in welfare status within a flock, and whether the feeding regime can be altered to keep the chicks growing slowly while experiencing less hunger.
