There are few references on the use of forage resources to feed outdoor sows. Which species should be planted, how should the grassland be organised and what are the zootechnical results?
The video presents the results of a trial testing the implementation of meadows grazed by pregnant sows whose ration is reduced in protein and quantity.
The video "Foraging of sows on high-protein grassland" presents the results of a trial conducted on the Trinottières pig experimental farm on 6000 m² of grassland, containing grasses and fodder legumes. The aim is to test rotational grazing on pregnant sows, whose concentrated feed is reduced in quantity and protein, and to observe the feeding behaviour of sows, the circulation of animals, and the consumption of feedstuff. The trial was seemed to support this method. However, it suggests that a full ration should be maintained at the end of the pregnancy. This tool is interesting for both farmers and advisors, and can also be used in conventional outdoor breeding. It can be used in any geographical area where animals have access to the outdoors.
