individually identified and assigned to eighteen pens (4 pigs
per pen). From 56.9±6.90 kg body weight until slaughter
(105.4±9.97 kg) pigs were fed two diets according to their
age (60 to 80 kg and 80 kg to slaughter). Within each age
period, 3 dietary treatments were formulated to contain 0 (C),
50 (PM) and 100 (PH) g of ensiled citrus pulp per kg on a dry
matter basis (DM). Diets with citrus pulp (PM and PH) were a
mixture of C feed with the respective amount of fresh ensiled
citrus pulp and different amounts of soya and lysine were
added if necessary. Diets were formulated to be isoproteic
and isoenergetic (Table 1)
