Abstract excerpt
Feed conversion has been described as a "milk yield-tissue balance-appetite complex" in which energy inputs from feed intake and tissue balance impose a limit on milk yield. An experiment at the Agricultural University of Norway provided data to estimate genetic parameters of variables in this "complex." Fat-corrected milk yield, NE from roughage (NER) and BW were measured weekly on 353 first-lactation,...
