You need to give more vitamin C rich veg than normal to pregnant and nursing sows; they need about double the amount. Guinea pigs can't produce their own vitamin C, so you need to feed extra for the pups to develop properly and build up their own parcel.
You also need to feed more calcium during this period for the pups' bones. This can be best done by feeding extra alfalfa hay on top of the normal hay.
Continue to give extra vitamin C and alfalfa hay for as long until Flower has finished nursing her own pups-to-be.
- unlimited hay, 50-80% of the daily food intake
- topped up bowl of pellets
- 50g of mixed veg per piggy per day
- freshly changed water
Please do not be tempted to feed a pregnant sow more! You are aiming for pups of an ideal size, not huge babies that are in danger of getting stuck during birth.
