McNay Research and Demonstration Farm
Our group has previously reported that percentage of fatty acids within the total fatty acids shows evidence of being under genetic control. In more recent work, we are conducting a comparison of heritability estimates when the fatty acids are expressed as a percentage of the lipid (% fatty acid within the total fatty acids) or expressed as a concentration within the beef (mg fatty acid/g of beef). Expression of fatty acid concentration as mg fatty acid/g of beef is dependent upon both the concentration of lipid in the beef and the concentration of fatty acid within the lipid.
