More comfort, less stress can solve sow infertility says Bpex

But with vets in some parts of the UK reporting increased incidence of reduced appetite resulting in failure to come on heat and, therefore, increased weaning to service intervals, producers are likely to be looking at ways of improving sow fertility.

BPEX AI programme manager Angela Cliff says there is no definite pattern with infertility, so it is vital to provide sows with the most comfortable, stress-free environment possible, so the impact of any extraordinary stressors will be reduced.

"Younger sows, particularly gilts, are more prone to reduced fertility, delayed oestrus, failure to cycle and increases in return rates."

Specialist pig vet Andrian Cox reckons this year's hot and humid summer period has resulted in many sows showing reduced appetites.

"Where that is the case, I have advised feeding twice or even three times a day and providing extra water, combined with keeping room temperature as low as possible by keeping creep feed lights off whenever possible."
