During the finishing phase, it is important to ensure an optimal overall environment for the finishers. An important part of this environment is the light climate.
Light can stimulate feed intake but can also prevent undesirable behaviour. A correct light climate enables finishers to see better, which makes them feel more comfortable in their pens and with their pen-mates.
There are different ways to rear finishers, with several combinations possible of housing in smaller groups, in larger groups and with different feeding systems. In each system, social contact between finishers is very important to prevent undesirable behaviour. Light can contribute to improving these social contacts.
Conventional housing system
Finishers are conventionally reared in groups. Correct lighting can significantly improve several aspects of the finishing period. Feed and water intake can improve, as well as the degree of socialisation of the pigs.
