ABSTRACT

The experiment was conducted to determine the behavioural response of Ross broiler chickens fed diets containing different levels of wheat distiller’s dried grains with solubles (wDDGS).Four groups of 36 day-oldRoss broiler chicks were weighed, wing tagged and distributed into four dietary treatments with four replicates each, for a 42-day trial in a one-phase feeding system in a completely randomized design. Birds of each replicate were randomly assigned to circular floor pens of 1.2 m2 with wood shavings as litter material at different sides of the experimental room to achieve uniform distribution of bird groups. Each pen was equipped with a suspended infrared heat lamp, plastic chick feeder and plastic drinker. Four iso-nitrogenous diets, with varying metabolisable energy, fibre and some amino acid contents, were formulated for the study. Diet A, which was the control contained 0% wDDGS while diets B, C, and D contained 10, 20 and 40% DDGS respectively. The diets and clean drinking water were provided ad libitum to these birds throughout the experimental period. Behaviours of birds were recorded weekly using mounted video cameras to film four sets of pens on consecutive days. Different behaviours of broiler chickens were significantly (P < 0.05) affected by age. Comfort behaviours (preening and dust bathing) as well as agonistic behaviours (aggression and pecking) were not performed frequently and were not affected by age.
