The effect of environmental temperature on the excretion time of sebum in different genotypes of cattle

The effects of hair density of beef cattle on Haematobia irritans horn fly populations

“…O' Kelly & Reich (1982) indicated that there are significant genotype by environmental interactions in the composition of sebum. The differences that occur between Bos indicus and Eos tarusus in sebum production and excretion time could be explained by differences in blood flow rate to the skin along with differences in the rate of substrate supply to the glands (O'Kelly & Reich, 1984).…”

“…The number of hairs per area of the photograph was converted to the number hairs per square centimetre of skin. & Reich (1984), samples of hexane containing sebum were filtered through Whatman No. 3 paper.…”
