UNASSIGNED: Two experiments were conducted to determine the effects of @entity10102 , phytase, fiber, and @entity1460 oil on apparent total tract digestibility (ATTD) and standardized total tract digestibility (STTD) of @entity9495 and on ATTD of P in fish meal fed to growing @entity1707 . In Exp. 1, 40 growing @entity1707 (initial average BW: 19.16    2.04 kg) were randomly allotted to 1 of 5 diets with 8 @entity1707 per treatment and placed in metabolism crates. Four diets were used in a 2    2 factorial design with 2 levels of @entity10102 (0 or 0.7%) and 2 levels of microbial phytase (0 or 500 phytase units/kg). The diet containing no @entity10102 was based on @entity969 , cornstarch, fish meal, casein, and @entity1460 oil, and the diet containing 0.7% @entity10102 was based on @entity4336 , @entity4336 germ, fish meal, casein, and @entity1460 oil. A @entity9495 -free diet was used to determine basal endogenous losses of @entity9495 . Feces were collected from d 6 to 13 after a 5-d adaptation period. Results indicated that the ATTD and STTD of @entity9495 in fish meal and the ATTD of P increased ( < 0.001) if phytase was used and were greater ( < 0.05) in the diets based on @entity4336 and @entity4336 germ. Experiment 2 was conducted to determine the effects of fiber and @entity1460 oil on the ATTD and STTD of @entity9495 and the ATTD of P in fish meal. Fifty growing @entity1707 (initial average BW: 19.36    0.99 kg) were randomly allotted to 1 of 5 diets with 10 @entity1707 per treatment. Two diets contained @entity969 , cornstarch, fish meal, casein, and either 0 or 8% of a synthetic source of fiber. Two additional diets contained fish meal, casein, @entity4336 , and either 1 or 7% @entity1460 oil. A @entity9495 -free diet was also used. @entity1707 were housed individually in metabolism crates and fecal samples were collected. Results indicated that fiber increased ( < 0.001) the ATTD and STTD of @entity9495 and the ATTD of P, but the ATTD and STTD of @entity9495 or the ATTD of P were not affected by @entity1460 oil. In agreement with the results of Exp. 1, the ATTD and STTD of @entity9495 and the ATTD of P in the @entity4336 -based diet were greater ( < 0.05) than those in the cornstarch-based diet. In conclusion, phytase and fiber increased the ATTD and STTD of @entity9495 and the ATTD of P in fish meal, but inclusion of @entity1460 oil did not affect digestibility of @entity9495 or P. The observation that values for the ATTD and STTD of @entity9495 and ATTD of P are greater in @entity4336 -based diets than in cornstarch-based diets indicates that values for the digestibility of @entity9495 and P obtained in cornstarch-based diets may not always be representative for the digestibility in practical @entity4336 -based diets.

Effect of XXXX , microbial phytase, fiber, and @entity1460 oil on calculated values for apparent and standardized total tract digestibility of calcium and apparent total tract digestibility of phosphorus in fish meal fed to growing @entity1707 .
