Abstract: Fumaric acid (FA), level of dairy product in the diet and creep feeding were evaluated in three experiments using individually fed pigs (weaned at ca. 21 days and weighing about 6 kg). They were assigned at random to treatments. In Experiment 1, the treatments were: (1) no pre-weaning creep and no FA post-weaning, (2) no pre-weaning creep and 20 g/kg FA post-weaning, (3) pre-weaning creep and no FA post-weaning, and (4) pre-weaning creep and 20 g/kg FA post-weaning. In Experiment 2, the treatments were: (1) 50 g/kg dried whey, (2) 50 g/kg whey with 20 g/kg FA, (3) 50 g/kg whey with 30 g/kg FA, (4) 200 g/kg whey, (5) 200 g/kg whey with 20 g/kg FA, (6) 200 g/kg whey with 30 g/kg FA. In Experiment 3, the treatments were: (1) high dairy product (whey plus skim milk powder) diet, (2) high dairy product diet with 20 g/kg FA, (3) low dairy product diet, (4) low dairy product diet with 20 g/kg FA. The number of pigs per treatment in Experiments 1, 2 and 3 was 16, 10 and 10, respectively. All diets contained barley, wheat, herring meal and full-fat soybean meal. In Experiment 1, FA inclusion increased intake (518 ν. 466, s.e.d. 21.5 g/day, P < 0.05), daily gain (339 ν. 280, s.e.d. 18.1 g/day, P < 0.01) and improved feed conversion rate (1.55 ν. 1.70, s.e.d. 0.06, P < 0.05) in the first 3 weeks post-weaning. In Experiment 2, there was no effect of treatment. In Experiment 3, increasing the level of dairy product in the diet increased feed intake (P = 0.06) and daily gain (P < 0.05) and improved feed conversion rate (P < 0.01). The conclusions are that FA improved post-weaning performance and that increasing the level of dairy products in postweaning diets also improved performance.
