Metabolism of cystine by Merino sheep genetically different in wool production. 3. The incorporation of radio activity into wool fibres during and after intravenous infusions of L-cystine and its relationship to wool growth and efficiency of conversion of food into wool



Metabolism of cystine by Merino sheep genetically different in wool production. 3. The incorporation of radio activity into wool fibres during and after intravenous infusions of L-cystine and its relationship to wool growth and efficiency of conversion of food into wool



Australian Journal of Biological Sciences 26(2): 465-476



For parts 1 and 2 see NAR 43, 8029 and 8030.3. Twelve mature ewes from a flock selected for high clean fleece weight (Fleece Plus) and 12 from a flock selected for low clean fleece weight (Fleece Minus) were given daily 500 or 1100 g chaffed lucerne hay. After 40 days each ewe was given by vein L-cystine-35S for 12 to 14 h. During the final 7 to 9 h of infusion the 35S activity in plucked fibres increased linearly with time.
