Summary Homozygous transferrins of adult cattle are made up of two strong pairs and one weak pair of protein bands on starch gel electrophoresis. Foetal transferrins have only the slower band of each pair with the fastest band of the three being much

Two divergent lines of sheep were produced by selection on an index of testis diameter adjusted for body weight at 6, 10 and 14 weeks of age. There were correlated changes in growth patterns, such that animals in the high and low lines were of a simi

Divergent selection has resulted in two lines of lambs (high and low) that have a 5-fold difference in their ability to release luteinizing hormone (LH) in response to 5 micrograms of gonadotrophin-releasing hormone (GnRH). Baseline gonadotrophin con

The concentration of prostaglandin (PG) F-2alpha in ovarian arterial blood was compared to that in aortic and carotid blood at different stages of the ovine oestrous cycle, and its concentration measured in the ovarian artery following the infusion o

Analysis of the numerical proportions of Soay, Orkney and Shetland sheep of different colours together with test matings, produced results compatible with the hypothesis that these breeds have a multiple allelic series at locus A, white (A1) being do

Plasma LH levels were examined at 1 1/2-hr intervals in ram lambs of the Finnish Landrace, Border Leicester and Cheviot breeds on three occasions at 3-week intervals by radioimmunoassay. On each occasion, the mean plasma LH concentration was found to

The dynamics of FSH and LH secretion were studied in sheep genetically selected for High (H) and Low (L) rates of testis growth. Gonadotrophin secretion had previously been shown to be affected in the ram lamb with H-line lambs more sensitive to ster
