[The fat mobilization syndrome in guinea pigs (Cavia porcellus L.)]

Feeding experiments were applied to 82 guinea pigs, different by age, sex, and stage of reproduction, and showed that high-energy feeding and subsequent feed withdrawal could trigger off with high probability a fat mobilising syndrome with clinically manifest ketosis in animals in gravidity and lactation or subclinical ketosis in all non-gravid individuals. High-energy or restrictive feeding alone did not cause in guinea pigs any disease along the lines of gravidity toxicosis. Aspects relating to aetiological and pathogenetic comparability with ruminants are discussed in some detail.
