Use the right feeding line

The manufacturer's guide lists up to 55g a day for young or growing guinea pigs, up to 50g for adult maintenance and up to 55g for lactating guinea pigs. This food is complementary, so the same guidance calls for unlimited good-quality hay, a small daily quantity of fresh greens and constant access to fresh water.

Why we chose it

The 10KG format is the deciding feature for homes feeding more than one guinea pig or buying less often. The clear life-stage ration ranges and full analytical panel make it possible to compare the food on more than bag size.

Full description

A larger guinea pig food bag is easiest to judge by the daily ration, because bag size alone says nothing about how quickly a group will use it.

Mr Johnson's Advance Guinea is a 10KG complementary food for guinea pigs. Its composition starts with wheatfeed, alfalfa, barley and oatfeed, followed by soya bean meal, sunflower seed meal, vegetable oil and fat, carrot, calcium carbonate, sodium chloride, Verm-X herb blend, Bio-Mos, glucosamine and De-odorase. The analysis declares 18% protein, 13% fibre, 4% oils and fats and 6% ash, plus calcium, sodium and phosphorus. Vitamins A, C, D and E and several trace elements are also declared.

Use the right feeding line. The manufacturer's guide lists up to 55g a day for young or growing guinea pigs, up to 50g for adult maintenance and up to 55g for lactating guinea pigs. This food is complementary, so the same guidance calls for unlimited good-quality hay, a small daily quantity of fresh greens and constant access to fresh water.

Who it's for: homes with guinea pigs that can use a 10KG bag sensibly and want a single-component complementary food with a published analysis and separate feeding ranges for growth, maintenance and lactation.
