Article in English: When you are checking on your guinea pig, listen for any groaning. Your guinea pig will give a distinctive groan when she is going into labour. Even if you've never heard it before, chances are you’ll know it when you hear it. It should be under an hour and there should be about 5 minutes between pups. The sow will sit up with her head between her legs and make small ‘hiccups’, these are contractions.  Do not hold the mother. Do not crowd the mother — have only one person in the room, but another on standby to make calls if necessary. Do not intervene or touch the pups unless you need to. There is no need to remove other sows, they may even help with the pups. If any sign of complication or distress does arise, do not hesitate and contact the vet immediately. Signs of complication are:  Mother strains for 15 minutes without producing a pup. Total labor is over one hour. Mother starts making "extreme" stress calls Mother seems to give in, appearing exhausted Mother salivates/foams at mouth Excessive bleeding (more than a tablespoon) The vet may try to manipulate the piglet into a position where the mother can pass it. However, a caesarean surgery may be required. Occasionally, with large litters, if the pups emerge too quickly, the mother will not have time to break the amniotic sac herself. In these cases, and only if you are sure the mother will not do it herself, carefully pick up the pup with a clean towel and remove the sac yourself, clearing any fluid from the face. Do not use your fingers or nails as you could accidentally scratch the pup’s eyes. Whilst a pup becoming stuck in the birth canal or born breech is common, never intervene yourself. Only a skilled and experienced veterinarian should attempt to manipulate the position of pups before they are born. If a pup is not, carefully lift it up and hold it at arm’s length. Its head should be away from you. Spin around once. The force should free any blockages from its throat and help it to start breathing. If this does not work, gently rub its back...

Summary in Indonesian:
Dengarkan baik-baik. Hadirlah saat proses melahirkan. Saat kelahiran, pantau tanda-tanda komplikasi dan bersiaplah menghubungi dokter hewan bila diperlukan. Terlibatlah hanya bila diperlukan. Periksa tiap anak bernapas atau tidak. Periksa betina sudah menyingkirkan tanda-tanda kelahiran atau belum. Pastikan betina tertarik pada anak-anaknya, mengingat pada kelahiran pertama, terutama pada betina muda, mereka mungkin akan kabur dari anak-anaknya seakan-akan bingung.
