The sire effect on litter size: small, but usable for breeding

Sire effect – what does this mean for the sow farmer? 

The biggest lever remains the sow (genetics + management). However, the boar makes an additional, measurable contribution. 

Deceive individual cases: With small effects, it takes a lot of litters – otherwise, chance wins. 

Documentation makes the difference: recording parity, live/stillbirths, fostering, pre-wean mortality and health events cleanly. 

Returning data: The better farms and studs structure data, the better evaluations will be – and the more precise breeding decisions will be.
