Feed for laying hens: a minimum of insoluble fibre is recommended to limit the feather pecking. High feed energy level provokes feather pecking, reduces the feed efficiency. Feed lower in energy, richer in coarse insoluble fibre, will allow a good energy efficiency to be obtained (expressed in kcal) and plumage to be maintained. This strategy could be particularly beneficial for alternative production (free range, organic…), especially in the absence of ground litter. The hens’ consumption time depends on the fibre content of the feed. Feather pecking is inversely proportional to consumption time. Floor system: Where hens are reared on the ground or in henhouses, it is best therefore to avoid energy levels which are too high, and to incorporate a minimum of cellulose. The use of a minimum of wood shavings on floor is recommended.
