1A total of 180 nursery pigs (initial BW 6.4 kg) were used in a 24-d trial to determine the effects of increasing PEP-NS on nursery pig growth performance.
2The pretest diet was a common diet fed the first 7 d postweaning and was in pellet form.
3Phase 2 diets were fed from d 0 to 14 and were in meal form.
4Phase 3 diet was a common diet fed from d 14 to 24 and was in meal form.

6Special select menhaden fish meal (SMFM): Omega Protein Corp., Houston.
7Provided (per kilogram of complete diet) 11,025 IU of vitamin A, 1,654 IU of vitamin D, 44 IU of vitamin E, 4.4 mg of vitamin K (as menadione dimethylpyrimidinol bisulfate), 55.1 mg of niacin, 33.1 mg of pantothenic acid (as D-calcium pantothentate), 9.9 mg of riboflavin, 0.044 mg of vitamin B12, 16.5 mg of Cu as CuSO45H2O, 165.4 mg of Fe as FeSO4H2O, 39.7 mg of Mn as MnSO4H2O, 0.30 mg of Se Na2SeO3, 165.4 mg of Zn as ZnO, and 0.30 mg of I as C2H2(NH2)22HI.
8Phyzyme 600 (Danisco Animal Nutrition, St. Louis, MO) provided 231 phytase units/kg, with a release of 0.10 available P.
9Values for select menhaden fish meal were from the NRC (1998) and nutrient profiles for PEP-NS were provided by the manufacturer and used in diet formulation.
10Amino acid digestibility values for spray-dried plasma and respective vegetable protein carriers were averaged and used as the estimate of standardized amino acid digestibility of amino acids in PEP-NS.

1A total of 300 nursery pigs (initially 5.4 ± 0.84 kg and 19 ± 2 d of age) were used in a 25-d trial to determine the effects of PEP2 on nursery pig growth performance. There were 12 pens per treatment with 5 pigs per pen.
2Contained no specialty protein products.
3Contained 4% spray-dried animal plasma in phase 1 (d 0 to 11) and 4% select menhaden fish meal in phase 2 (d 11 to 25).
