Effects of hydrolyzed vegetable protein or hydrolyzed vegetable and meat protein blend on nursery pig performance
A total of 280 pigs (PIC 327 × 1050, initially 7.6 kg) were used in a 28-d trial to evaluate the effects of hydrolyzed vegetable protein or a blend of hydrolyzed vegetable and meat protein for nursery pigs. Three days after weaning, pigs were allotted to 1 of 4 dietary treatments in a completely randomized design, balancing for initial BW and gender. There were 10 pens per treatment with 7 pigs per pen. The 4 treatment diets were: (1) no added specialty protein source (negative control); (2) 6% select menhaden fish meal; (3) 5% hydrolyzed vegetable protein (Hydr SF 52, International Ingredient Corporation, St. Louis, MO), or (4) 6.5% hydrolyzed vegetable and meat protein blend (HDSF Protein; International Ingredient Corporation). Treatment diets were fed from d 0 to 17 and a common Phase 2 diet was fed from d 17 to 28. From d 0 to 17, pigs fed the negative control diet had improved (P<0.05) G:F compared with pigs fed diets with Hydr SF 52 or HDSF Protein. No differences (P>0.55) in ADG and ADFI were detected among treatments. From d 17 to 28 (common period), no difference (P>0.27) was observed in growth performance between pigs previously fed any of the treatment diets. Overall (d 0 to 28), no differences (P>0.36) were observed in ADG, ADFI, or G:F. Although pigs fed the hydrolyzed vegetable and meat protein sources had similar performance to pigs fed fish meal, definitive conclusions regarding efficacy of the specialty protein sources tested cannot be made because performance was also similar to pigs fed the negative control diet.
