This thesis is a study of the small animal colonies operated by the animal nutrition laboratory in the Department of Animal Husbandry. The four animal units studied are the albino rat, albino mouse, guinea pig and rabbit. The management practices used for each species are described fully. They include the housing, feeding, breeding and control of disease methods utilized. The factors discussed in the housing of the animals are the space utilization per animal and the type of cages. In addition, scale drawings and illustrations of the cages and cage racks are included. The method of feeding and the formula of each ration for each species is reported. The system of breeding used in each of the colonies is described. Control of disease is discussed with reference to the sanitation procedures practised. Growth and production data are reported for each species and a comparison made with the data published in the literature for other colonies. The number of animals involved in the study are 1,700 rats, 258 mice, 73 guinea pigs and 85 rabbits. The growth data includes size of litter, birth weights and weekly weights there after until weaning age. The production data comprises the percentage fertility and percentage weaned. In addition the results of a cost survey is reported. The cost per animal for each species includes the cost of housing, feeding and labour. The results reported here are comparable to those reported elsewhere. / Land and Food Systems, Faculty of / Graduate

The anti-estrogenic properties of birdsfoot trefoil (Lotus corniculatus) and yellow pine (Pinus ponderosa) needles were studied. Oral administration of a water-soluble fraction of an acetone extract of birdsfoot trefoil was found to decrease uterine weight of immature female mice. The estrous cycles of rats receiving this extract in the ration, were not disturbed. Specially prepared aqueous fractions of an acetone extract of yellow pine needles decreased the uterine weight of mice. In further experiments, immature female mice were fed 0.040 mcgms. and 0.020 mcgms. diethylstilbestrol (D.E.S.) per gram of feed. When a water-soluble fraction of pine needle extract was administered, it did not affect uterine weight significantly in the 0.040 mcgm. D.E.S. group, but markedly and significantly decreased uterine weight in the 0.020 mcgm. D.E.S. group. This pine needle extract also interrupted the estrous cycles of mature rats, causing a prolonged diestrus. Chromatographic studies indicated that the pine extracts probably do not owe their anti-estrogenic activity to pinosylvin or its mono-methyl ether. / Land and Food Systems, Faculty of / Graduate
