Summary:

The welfare of broiler breeders during rearing is commonly impaired, as the restrictive feeding commonly practiced, and the management procedure leaves the chicks feeling hungry and frustrated about their inability to feed. This study attempted to improve the welfare of broiler breeders by making simple and practical changes to the feeding system. The effect on hunger and frustration experienced by the broiler breeders was compared when the feed was scattered in the litter and/or feeding the chicks twice a day. Scatter feeding and feeding two meals a day did not have a significant affect on various hunger indicators such as compensatory feed intake, plasma glucose/non-esterfied fatty acid ratio and plasma corticosterone concentration. Scatter feeding did reduce the amount of time the chickens spent pecking at an object, but they spent a large amount of their time performing foraging behaviours, thus it is not clear if scatter feeding was effective at improving the welfare of the broiler breeders. Feeding twice a day increased the amount of time the chickens spent walking, which could be how they expressed their frustration about their inability to eat, or they were searching for more food. Thus, the welfare of the broiler breeders during was not improved by feeding two meals a day, scatter feeding or by combining the two treatments as the birds still demonstrated behaviours that indicate that they are still hungry.
