We evaluated the apparent ( AID ) and standardized ileal digestibility ( SID ) of amino acids ( AA ) in spray‐dried egg ( SPE ) and albumen powder ( AP ) compared with spray‐dried porcine plasma ( SDPP ), dried porcine solubles ( DPS ) and fish meal ( FM ). Additionally, the effects of these egg byproducts as a replacement for conventional animal proteins on the performance and nutrient digestibility of piglets were studied. In Exp. 1, six barrows fitted with ileal T ‐cannulas were allotted to a 6 × 6 L atin S quare design and fed six diets. The AID and SID of AA were generally higher in AP and FM ( P < 0.01) than in the other protein sources. In Exp. 2, 150 piglets weaned at 21 days, were fed diets containing the five protein sources for 3 weeks. Weight gain of piglets fed SDPP was the highest among the treatments. Dry matter and protein digestibility for pigs offered SDPP were higher ( P < 0.01) than those offered FM and DPS . AP decreased ( P < 0.05) E scherichia coli counts in the cecum. DPS decreased ( P < 0.05) serum diamine oxidase compared with SPE . In conclusion, AP and SPE are competitive with traditional animal protein sources and can be successfully fed to piglets without compromising performance.
