Evaluation of Bovine Plasma Source and Whole Dried Milk in Nursery Pig Diets on Growth Performance
A total of 360 barrows and gilts (PIC 359 × C29; initially 6.2±1.4 kg BW and 19 d of age) were used in a 24-d experiment evaluating different specialty ingredients on nursery pig growth performance. This experiment was conducted in a commercial environment (Cooperative Research Farm Nursery; Sycamore, OH). At weaning, pigs were allotted to pens by initial BW to 1 of 4 treatments in a completely randomized design. There were 9 replicate pens per treatment with 10 pigs per pen. Experimental diets were fed from d 0 to 10 with a common diet fed from d 10 to 24. Experimental diets were: 1) Negative control (NC; 5% fish meal), 2) NC + 5% bovine plasma A (AP920,APC Inc.; Ankeny, IA), 3) NC + 5% bovine plasma B (Promax; Protena, Nicauragua), and 4) NC + 5% dried whole milk (NutriGold; International Ingredients Corporation Inc., St. Louis, MO). All diets were balanced on SID Lys and lactose and were fed in pellet form. From d 0 to 10, pigs fed Plasma A and Plasma B had greater (P<0.01) ADG and ADFI than pigs fed the NC or NutriGold diets. Pigs fed Nutrigold also had increased (P<0.01) ADG relative to pigs fed the NC diet. Also, G:F was greater (P<0.001) for plasma and NutriGold containing diets compared to the NC. During the common period (d 10 to 24), there were no differences for ADG or ADFI, but pigs previously fed NC had greater (0.810 vs. 0.765; P<0.01) G:F compared to those previously fed Plasma A. Overall (d 0 to 24), pigs fed Plasma A and B had greater (P<0.02) ADG and ADFI than NC pigs. Furthermore, pigs fed Plasma B had increased (P<0.04) ADG relative to pigs fed Nutrigold. In summary, both plasma sources increased intake and growth with no differences between sources. NutriGold also improved performance compared to the NC.
