Two experiments, each consisting of 2 trials, were conducted to determine the effect of salmon protein hydrolysate (SPH) and spray-dried plasma protein (SDPP) fed during the first week post weaning and their subsequent effect on growth performance of weanling pigs. Pigs were fed in a 3-phase feeding program with a duration of 7 d for phase 1 in both experiments, and 14 or 15 d for phase 2, and 7 or 8 d for phase 3 in Exp. 1 and 2, respectively. Dietary treatments were only fed during phase 1; while the same diet was fed to all pigs in phases 2 and 3. Pigs were blocked by initial BW and sex and littermates were balanced across treatments. Data from the 2 trials within each of Exp. 1 and 2 were combined and analyzed together; there were no treatment × trial interactions (P > 0.10). In Exp. 1, 324 weanling pigs (10 reps of 5 or 6 pigs per pen) with an average initial BW of 6.4 ± 1.3 kg were assigned to: (1) a control diet with no SPH or SDPP, (2) 1.5% SPH, (3) 3.0% SPH, (4) 1.5% SDPP, (5) 3.0% SDPP, or (6) 1.5% SPH + 1.5% SDPP. Experiment 2 was similar to Exp. 1, but red blood cells were removed from all diets to reduce diet complexity. In Exp. 2, 320 weanling pigs (14 reps of 5 or 6 pigs per pen) with an average initial BW of 5.4 ± 1.2 kg were assigned to: (1) a control diet with no SPH or SDPP, (2) 1.5% SPH, (3) 1.5% SDPP, or (4) 1.5% SPH + 1.5% SDPP. Three batches of SPH were used and each batch was analyzed for AA composition. In Exp. 1, the inclusion of SDPP or SPH during phase 1, did not affect (P > 0.10) ADG, ADFI, or G:F compared with pigs fed the control diet. There were no carryover effects on growth performance in any of the subsequent phases. Overall G:F, was greater (P = 0.08) in pigs fed the 1.5% diets compared with pigs fed the 3.0% diets. In Exp. 2, there were no differences (P > 0.10) in ADG, ADFI, or G:F among pigs fed the SPH or SDPP diets compared with pigs fed the control diet. Pigs fed the combined diet had greater (P < 0.10) overall ADFI compared with pigs fed the control diet, but similar to pigs fed the SPH and SDPP diets. These results indicate that the inclusion of up to 3% SDPP or SPH in diets fed during the first week post weaning did not affect growth performance of weanling pigs, and there were no subsequent carryover effects. Salmon protein hydrolysate did not affect growth performance of weanling pigs and may be considered as an alternative protein source in diets for weanling pigs. |
