TI  - Endocrine regulation of metabolism in sheep given kale (Brassica oleracea) and 
      ryegrass (Lolium perenne)-clover (Trifolium repens) fresh-forage diets.
PG  - 165-73
AB  - Diets of fresh kale (Brassica oleracea) and ryegrass (Lolium perenne)-clover 
      (Trifolium repens) herbage were fed to growing sheep in three experiments. In 
      Expts 1 and 3 the sheep were confined indoors and fed at hourly intervals, and 
      all were given supplementary iodine to counteract kale goitrogens. Lambs grazed 
      the two forages for 24 weeks in Expt 2, with and without intramuscular injections 
      of iodized oil. The kale and herbage contained respectively 11 and less than 0.1 
      g S-methyl-L-cysteine sulphoxide (SMCO)/kg dry matter (DM) and values for readily 
      fermentable: structural carbohydrate (CHO) were 3.1 and 0.8, respectively. Blood 
      samples were withdrawn from indwelling catheters (Expts 1 and 3) or venipuncture 
      (Expt 2) and the plasma analysed for a range of hormones using radioimmunoassay 
      procedures. Glucose irreversible loss (GIL) was measured in Expt 1 using primed 
      continuous infusions of D-[U-14C]glucose. Samples of adipose tissue were removed 
      from the shoulder area in Expt 3, and rates of D-[U-14C]glucose and 
      [U-14C]acetate incorporation and oxidation were measured in vitro, together with 
      the rate of glycerol release. In the presence of supplementary I2, kale feeding 
      was associated with an elevation in plasma concentration of free thyroxine (T4). 
      Regardless of I2 supplementation, sheep fed on kale had much higher plasma growth 
      hormone concentrations than sheep fed on ryegrass-clover herbage, and this was 
      accompanied by reduced plasma somatostatin concentrations. Plasma insulin and 
      glucagon concentrations were similar for sheep fed on the two diets; GIL tended 
      to be slightly but not significantly greater (9.4%) for sheep fed on kale than 
      for those fed on ryegrass-clover herbage.(ABSTRACT TRUNCATED AT 250 WORDS)
