What diet does a pregnant sow need?
- Pregnant sows need plenty of daily changed fresh water to drink, double the normal amount of vitamin C as well as extra calcium and protein. No other changes in foods or amounts are necessary if your guinea pig is on a good quality diet, i.e. plenty of good quality hay (up to 80% of the daily food intake), about 40g good quality pellets and 50g of mixed veg per day.
Vitamin C: One extra slice of bell pepper or some extra chunks of broccoli every day will do for the increased need of vitamin C.
Calcium: Adding calcium rich alfalfa/lucerne hay to your normal hay will help with forming the pups’ bones; this should be continued for the pups until the end of the nursing period.
Protein: Again, alfalfa hay is the best source!
Do not be tempted to feed much more than normal because a small litter of big pups can cause real problems during birth, especially in small, stunted and very young sows. You are aiming for an ideal birth weight, not a high birth weight for the pups. However, mums can certainly do with some rest and special pampering afterwards!
See a vet asap if a sow shows signs of pregnancy toxaemia (blood poisoning) - indicated by anorexia (not eating), a hunched/depressed appearance, excessive salivation and convulsions in advanced stages. Pregnancy toxaemia generally happens in the two weeks before and after giving birth, and is a metabolic disease that results from inadequate feed intake and/or stress. The condition is more frequent in warm weather and develops quickly.
It is not uncommon for sows to bleed a little bit during the first 24 hours after giving birth. However, any bleeding that is a constant or repeated trickle especially of fresh blood and amounts to more than a teaspoon full needs to be seen by a vet as soon as possible.
Any swelling/reddening around her bits in the days or weeks after giving birth needs to be seen by a vet as well. An infection of the womb can happen especially in sows that have been kept in filthy surroundings; it can be fatal for the mum if it is not seen quickly. In rare cases the uterus can prolapse (come out of her back). Please see a vet asap in all of these circumstances.
