From fertilisation to hatching one group of salmon embryos was reared at ambient temperatures (fluctuating around 1.6° C) and another at 10° C. At Gorodilov stages 28, 30 and 33 transverse sections of whole embryos were obtained for light and electron microscopy. Total cross-sectional areas, fibre numbers, fibre diameters and myofibrillar areas of the white(More)
Up-to-date annotated catalogues of known inherited disorders in dogs are freely available on the Internet, providing vital information to existing and prospective dog owners, dog breeders, veterinarians, geneticists and others interested in the occurrence and control of inherited disorders. These resources are the Canine Inherited Disorders Database (CIDD),(More)
The fat-free carcass weight of the obese mouse (ob/ob) is generally less than that of wild-type siblings. The aim of this investigation was to examine the effect of obesity on muscle weights and histochemistry and to determine whether any effects could be eliminated when the obesity was largely prevented or reduced by limiting food intake. For 5 muscles(More)
Much attention has been given over the years to animal welfare issues surrounding the seal hunt in Atlantic Canada. However, very little information is available on this subject in the scientific literature. This article reports the results of observations made by representatives of the Canadian Veterinary Medical Association at the hunt in recent years and(More)
Fetal growth is known to be correlated with the size of the placenta and the exchange surface area. Reduction in the growth of the materno-fetal exchange surface areas may be a mechanism by which the effects of maternal undernutrition on fetal growth are mediated. In the compact placenta of the guinea pig the exchange surface is equivalent to the peripheral(More)
The Snell dwarf mouse exhibits impaired growth of the anterior pituitary resulting in reduced levels of growth hormone and thyroid stimulating hormone. Ten dwarf mice and 10 phenotypically normal littermates were killed at 33 days of age. M. biceps brachii (a predominantly fast muscle) and m. soleus (a relatively slow muscle) were removed from each animal(More)
