do they prefer qualitative food restriction to quantitative food restriction?
Broiler breeders are fed a restricted quantity of high quality food (quantitative restriction) and show signs of hunger (high food motivation, activity and abnormal foraging behaviour). An alternative is to provide larger quantities of lower quality food (e.g. high in fibre; qualitative restriction), although the welfare benefits of this remain controversial. Preference testing enables us to ask the animal whether its welfare is improved: we will offer broilers choices between large portions of low quality food and small portions of high quality food (portions designed to achieve equal growth), and furthermore explore the basis and strength of any preference. This project is PhD studentship awarded to Louise Buckley and funded by the Universities Federation for Animal Welfare (UFAW).
