Nucleus herd with grandparent gilts bought in
If you opt for EgoFit with grandparent gilts bought in (db.03 or db.01), you can restrict animal movements on your farm and so stabilise the health of your herd. Grandparent gilts only are brought onto the farm – in low numbers (approx. 4% of the herd) and with long breaks in between – and then used to produce hybrid sows. The pure-bred breeding stock can be purchased at different ages. Genetic progress on the farm is ensured by importing grandparent gilts and using breed line semen. This form of homebred restocking is already successfully implemented with smaller herds.
