“…The correlation between mean volume of individual sweat glands in an area and sweating rate was negative, and the correlation between total sweat gland volume in an area and its sweating rate was not significantly different from zero. This agrees with Nay and Dowling (1957) who found no evidence of an association between sweat gland size and sweating rate.…”

“…Breeds and strains which are better able to control body temperature have the largest glands. Zebu cattle and their crossbreeds have been shown to have higher follicle density than British-breed animals (Nay and Hayman 1956;Turner, Nay, and French 1962), although Pan (1963) found no significant difference between Jersey and Sahiwal cows. Pan, Donegan, and Hayman (1969) showed there was a positive correlation between the density of a sweat gland population in a body region and its sweating rate.…”

“…Differences in sweat gland size have been demonstrated between different breeds of cattle and between different strains within breeds (Nay and Hayman 1956;Nay and Dowling 1957;Nay and Hayman 1963;Pan 1963). Breeds and strains which are better able to control body temperature have the largest glands.…”

Significant differences in sweating rate between micro-areas of cattle skin have been demonstrated and the differences in morphology between these contrasting areas investigated.Variation in sweating rate over the skin was most marked when the coat was longest and follicle activity and sweating rate least.Among the characters most closely related to sweating performance were percentage of follicles in anagen and arterial supply to the sweat gland layer. Neither mean sweat gland volume nor follicle density had a direct effect on sweating rate.The growth phase of the hair follicle has a strong influence on the capillary supply to the sweat gland and this appears to be a critical factor in sweat gland performance.

Using measurements made on cows in the herds of the Hannah Research Institute (Ayrshire), the West of Scotland Agricultural College (Ayrshire and Friesian) and in the twin herd of the Animal Breeding Research Organisation (Ayrshire), repeatability and heritability estimates were obtained for three hair follicle and four sweat gland traits. Average repeatability was high (50-70%) for all characters except angle of slope of the hair (18%). Heritability estimates were extremely variable among the different herds and methods of measurement but there was evidence of considerable genetic variation, particularly for sweat gland traits. The most consistent heritability estimate (30-45%) was given by the ratio of sweat gland length to diameter. The potential use of skin types for the selection of cattle for tropical regions is discussed.

“…Breed differences in sweat gland size and distribution over the body surface have been crudely established by linear measurement or by approximating glands to crude geometric shapes in cattle 18–23 and other bovids 24 . Tropical cattle are reported to possess larger and more numerous glands on thermal windows, e.g.…”

Stereological techniques were used to assess seasonal influences on morphometric characteristics of hair follicles, sweat and sebaceous glands in abattoir pelts of ponies (PN), thoroughbred (TB) and non-thoroughbred (NTB) horses. Volume density of sweat glands increased significantly from winter (0.061) to summer (0.098) in TB, and showed no change in NTB and a positive tendency in PN. There might be a body surface area : volume effect for sweat gland parameters as PN had smaller values than either TB or NTB, probably attributable to control of heat loss in winter. In summer, the skin remained thick and the volume density of sebaceous glands was increased in NTB, in contrast to TB where both were decreased. It is possible that in summer, sebum has a particular importance in NTB to enhance wicking of sweat through the pelt. TB showed significantly higher volume measurements of sebaceous glands than NTB and PN for winter: sebum has probably a special importance for water-proofing in TB in winter. PN showed no significant seasonal changes in sebaceous glands, but had a thinner summer skin. Winter values for hair follicle volume density between equine groups were similar (TB, NTB 0.066; PN 0.059), as was skin thickness (1.14-1.19 mm). The volume density lowered significantly in summer in TB and NTB. The volume of hair follicles under a unit area of skin surface decreased significantly in TB and nonsignificantly in NTB and PN. The seasonal adaptations of the skin shown here were most pronounced in TB and differed between breeds.
