Evaluation of procedures to predict fat-free lean in swine carcasses12
Autor: H. Sellers, Rodger K. Johnson, O. W. Robison, Michael D. Tokach, John W. Mabry, R.K. Miller, R. Goodwin, Eric P. Berg
Publikováno v: Journal of Animal Science. 82:2428-2441
The objectives were to develop equations for predicting fat-free lean in swine carcasses and to estimate the prediction bias that was due to genetic group, sex, and dietary lysine level. Barrows and gilts (n = 1,024) from four projects conducted by t
