Monkey welfare

Abstract

The nutrition of laboratory animals 87 proximal part of the flexure of the small colon which may be YO calcified as to appear like the stem of a clay pipe (Pl. 2 , 2) with the lumen of the gut almost completely obstructed. Histologically the lesions resemble those characteristic of hypervitaminosis D. Summarizing, I would say that unless an adequate diet is provided at all times to breeders and growers, the door may be opened to epidemic disease with disastrous results, or the results of experiments will be difficult to interpret if guineapigs matched in weight vary greatly in age or guinea-pigs of the same age vary greatly in physiological development. I would also suggest that the nutritional requirements of the guinea-pig require further study particularly in regard to the part played by hay. PI. 2.

Observations on a Successful Breeding Colony of the Marmoset, Oedipomidas Oedipus

“…None-the-less, we discontinued the U-V exposures in favor of an increase in dietary vitamin D since it was too difficult, in any case, to provide substantial U-V exposure to a colony as large as ours. References relevant to the use of ultra-violet light, vitamin D require ments, osteomalacia and sensitivity to parathyroid hormone are given by Halloran [31] and others [10,22,27,28,40,41,44,46,48,49,50,60,70,72,75,84]. When the vitamin D supplementation was begun, the total amount added to the diet was set at 1000 I. U./animal/day.…”

“…Several other laboratories are, or have been, interested in estab lishing colonies of these small, South American prim ates [10,19,21,22,24,27,28,40,41,44,46,48,49,50,59,65,68,71,73,75,80,84], Additional publications show a growing appreciation of their use fulness in m any biomedical areas [3, 5-8, 11, 12, 14, 16-18, 20, 23, 29, 30, 34, 43, 45, 51-53, 62, 70, 72, 76]. This report, then, serves to review certain findings of other investigators and to chronicle some Hampton, H ampton and Landwehr of our experiences in order to help establish this group of prim ates as laboratory subjects.…”

Problems of Rickets in Monkeys and Apes

“…A degree of success was achieved when Dr H S Lucas was Pathologist at the London Zoo. He exposed marmosets to ultra violet light (UVL), and continued his experiments with Margaret Hume subsequently at the Lister Institute (Lucas et al 1927, Lucas et al 1937, Hume 1957). This treatment had the effect of halting all further skeletal disease in the marmosets; however, the marmosets were given boiled milk ad lib.…”
