ABSTRACT


Juan Guillermo Rosa W.1 y Rodrigo Venegas R.2
 

During 1970 two trials were carried out at the Carillanca Experiment Station in order to observe the performance of growing finishing pigs (28-100 Kg live weight) when feeded with acidulated rapeseed soapstock or beef tallow in oat rations.
In trial I fatty acids from the refining of adible rape-seed oil were used at the following levels: 0-2-4-6 and 8%. In trial II the pigs received beef tallow obtained from the slaughter house, at the same levels as in trial I.
