Résumé anglais
Background
• In France, 50 % of organic sows are raised in free range systems
• 80 % of the production cost are feed costs
The Classical feed for pregnant sows consists of
40 % Cereals, 16% Maize 20% Wheat Bran, Minerals, dried Alfalfa, and about 15 % of protein components.
The research question now is:
Is it possible to replace this part with grazing?
The experimental design looks like this.
The Requirements are:
You need grassland rich in legumes
Rotating pasture with paddocks
Less feed (80% of control)
Less protein in supplied feed
Here are some results:
For energy pasture contributed 22% of the nutritional needs of the sows.
For digestible Lysine, it was 33%.
The feed costs per pregnant sow were 362 Euros in the control group. For pasture, feed cost was 294, plus 10 Euros for pasturing. Pasture resulted in 16% savings compared to the traditional method. It could be increased with a longer pasturing season
Here are some recommendations:
If there is too much competition at feeding, then individual feeding in the refectory is recommended.
We observed that sows show less interest to pasture at the end of gestating period. We recommend to go back to complete feed 3 weeks before farrowing.
If pasturing is not possible, e.g. because grassland production is too low, use silage instead.
This video highlights OK-Net EcoFeed research on rotational grazing to replace protein components in organic pregnant sows. By reducing feed to 80% of control, it was found that pasture can replace 22% of energetic nutritional needs in sows. Pasture resulted in 16% savings compared to the traditional method. It could be increased with a longer pasturing season.
Key recommendations include: Here are some recommendations: If there is too much competition at feeding, then individual feeding in the refectory is recommended. We observed that sows show less interest to pasture at the end of gestating period. We recommend to go back to complete feed 3 weeks before farrowing. If pasturing is not possible, e.g. because grassland production is too low, use silage instead.
This tool is targeted towards organic pig farmers and farm advisors. Although research was done in France, it is relevant in similar systems across Europe and the world.
