Effects of Low Protein Diets on Lean Genotype Pigs: Growth, Feed and Nitrogen Intake and Fat Indicators
Feeding a low-protein diet supplemented with lysine to pigs from 40 to 115kg resulted in growth similar to the normal protein control diet but with more intramuscular fat, according to researchers based in the UK and Italy. However, six per cent more feed was needed to produce 1kg of liveweight gain over the period for the lysine-supplemented pigs than for the controls, which the authors attributed to deficiencies of other amino acids.
