Abstract

A total of 32 nursery pigs(8.9 ± 0.3 kg, PIC L337 × C24)were used to determine the interactive effects of nursery diet complexity and phase feeding on growth performance, caloric efficiency, diarrhea score and incidence, and economic return in nursery pigs.Pigs were randomly allotted to the following treatments 1) 2-phase complex2) 3-phase complex3) 2-phase semi-complexand 4) 3-phase semi-complex. Each treatment had 8 replications with 1 pig per replicate. Pigs and feeders were weighed at the end of each phase to calculate for ADG, ADFI, F/G, and caloric efficiency. Diarrhea score of each pen were assessed visually each day.Results showed that pigs fed with complex dietshad greater(P<0.05) ADG, ADFI, F/G, and caloric efficiency and were heavier (P<0.05) at day 0 to 6 however, no significant differences were observed in the subsequent phases. Phase feeding had no effect on pig weights, ADG, ADFI, F/G, and caloric efficiency. There was also reduced (P<0.05) incidence of diarrheawhen a 3-phase feeding program was employed.Margin over feed cost was greater (P<0.05) for pigs fed the 3-phase feeding program compared with those fed the 2-phase feeding program.In conclusion, feeding pigs with complex diets immediately postweaning improved nursery growth performance and the use of a 3-phase feeding programmaximized economic returns.
