	abstract = {The concentrations of cholesterol and triglyceride in blood plasma  were compared in two genetically distinct herds of Angus cattle. Any   concentration differences between the herds should indicate a realised  genetic response to selection for yearling weight.    Seventy-four yearling Angus cattle from the Waikite weight selection and   control herds were blood sampled after a 24-h fast in July, September and   November 1993 (heifers twice, bulls three times; n=178 samples). Plasma   cholesterol concentrations averaged 2.73 and 2.91 (s.e.d. 0.08) mmol/l in the   two herds, respectively (P<0.05), and triglyceride concentrations averaged   0.296 and 0.316 (s.e.d. 0.015) mmol/l, respectively. There was a 30kg   (14\%) difference in yearling live weight between the two herds (P.001).   Both metabolites showed moderate between-animal repeatabilities,  0.52+0.11 and 0.37+0.16 respectively, and there was a positive phenotypic  correlation of 0.40 between cholesterol and triglyceride concentrations  within herds.    These results show that a 14\% higher weight-for-age as a result of selection   was associated with a 6\% lower plasma cholesterol concentration. This was   consistent with our previously observed cholesterol difference in cooked beef   from the same herds.   },
