Guinea Pigs

Guinea Pigs are herbivorous rodents that have a well-developed caecum (hind gut) for fermentation of plant material. They require a high fibre diet consisting mostly of grass and hay. Unlike other small mammals, guinea pigs have a have a special dietary requirement for Vitamin C (Ascorbic Acid) which they obtain from fresh plant material and leafy green vegetables.

Young guinea pigs are born well-developed (precocial), fully furred, eyes open and mobile soon after birth. They have a high requirement for protein in early life to sustain their rapid growth rate, and this is provided by the mother's milk for upto 3 weeks of age.

Our products include Guinea Pig Milk Replacer, hand-rearing accessories as well as healthy supplements and treats for adult guinea pigs.

    To make an Impact Dose

    Weigh the animal and select the appropriate weight range from the feeding guide. Thoroughly mix the amounts of Impact powder and warm, pre-boiled water. An electric whisk may be used for larger quantities. Prepared Impact may be kept refrigerated for one day, or stored frozen for up to 2 weeks.

    Directions for Newborn Mammals

    Including cats, dogs, rabbits, rats, guinea pigs, horses, alpacas, cows, sheep, pigs, deer, zoo animals and eutherian wildlife (eg flying foxes & microbats).

    Impact should be fed as soon as possible after birth, and preferably before milk is fed. Impact may be absorbed for several days after birth, depending on the species, but is most effective in the first 12 hours.

    Newborns that have not received maternal colostrum should receive at least 2 doses of Impact within 48 hours of birth.

    First 12 hours after birth: Prepare an Impact Dose as described above and feed ¼ of the amount every 2 hours. Do not feed milk during this time.
    12 to 48 hours after birth: Commence feeding milk. Prepare an Impact Dose as described above and feed ¼ of the amount every 4 hours, in between milk feeds.

    Do not mix or feed Impact with milk.

    Directions for Marsupials

    Including kangaroos, possums, wombats, koalas, bandicoots, carnivorous marsupials and monotremes (echidna and platypus).

    Impact is ideally fed to pouch-bound marsupials within a week of first coming into care, as immunity from the mother’s milk can deplete significantly after 7 days and may be completely gone by 4-6 weeks.

    Impact may be fed as either a daily Maintenance Dose or a short-term Concentrated Dose.

    Maintenance Dose: Add 1g of Impact powder (1moderately heaped spoon) per 100mL of milk fed, repeated daily as required. Use as a preventative measure to provide a constant low-dose of immune support during care. 

    Concentrated Dose: Add 5g of Impact powder (5 moderately heaped spoons) per 100mL of milk fed. Repeat for up to 5 days, every 4 weeks, as necessary. Ensure joeys are well hydrated prior to feeding. Use when animals initially come into care, for sick or stressed animals or just prior to first pouch emergence (Wombaroo Age Factor of 0.6).
