英文摘要	The degu, a small rodent, is often kept as a pet. As precocial animals, degu pups are born highly developed with a birth weight of 13.5 to 14.6 g (litter size: 65 +/- 0.1). Within the first two weeks, the pups gain on average 1 to 1.5g body weight/day. Natural weaning occurs after the fourth to the sixth week of life. Degu pups have been observed to consume solid feed at the earliest on the sixth day of life. A prenatal transfer of maternal immunoglobulins (IgG) provides the pups with a passive immunity for a certain period of time. The neonates of rodent species can be reared even without an intake of colostrum. Degu milk is more concentrated (total solids: 26.9% +/- 5.8) than the milk of guinea pigs or chinchillas. The primary energy source in degu milk is the milk fat. The content of lactose in degu milk declines during the course of lactation. Milk replacers for canine puppies supplemented with vegetable oil, minerals and Lactobacillus preparations are recommended for rearing orphaned degus. Weaning of orphaned degu pups has been found to be successful after the tenth day of life. Nevertheless, suckling was predominant until day 10 to 20 and solid feed is digested more efficiently from the age of two weeks onwards. The gradual adaptation to supplementary feed (for example, pelleted compound feed or best quality hay with a low crude fibre content) reduces the risk of diarrhoea. Freeze-dried gut flora stabilizers are able to support the establishment of a healthy intestinal flora. The distance between the clitoris or urinary orifice and the anus is used to differentiate between the sexes of degus. There are anatomical peculiarities of male degus which have to be considered especially during castration (nonscrotal rodent, mesentery connection between testes and seminal vesicles).
