Figueroa, V.; Maylin, A.; Novo, O., 1991. Effect of low protein levels on the behaviour and on the carcass characteristics of pigs fed molasses B and torula yeast. Livest. Res. Rural Dev., 3 (3): 6-13

A total of 48 castrated male hybrid pigs with an initial liveweight of 30 kg were used to evaluate in four treatments the effect of two levels of protein (8 and 10%) and two intake systems (ad libitum and programmed) in diets based on molasses `B' and torula yeast as the only protein source. A fifth treatment of maize and torula yeast (12%) served as control. The pigs were slaughtered at 90 kg LW and carcass composition was determined. It was demonstrated that it is possible to reduce the level of protein below previously recommended requirements in molasses B - torula yeast diets, supplemented with methionine, without any detrimental effect on pig performance compared to a cereal diet with higher level of protein. The restriction in protein and protein:energy intake had no effect on carcass quality for molasses B fed pigs compared to pigs that received a diet based on cereal with a higher protein:energy intake.
