aTreatment diets were fed during phase 1 from d 0 to 7 and phase 2 from d 7 to 21, with a common phase 3 diet fed from d 21 to 33. All diets were fed in pelleted form.
bDiets were formulated with consideration of increased moisture content provided by LL and molasses. Concentration of diet components were initially decreased to allow for moisture loss during the pellet cooling process. Item (%) represents the percentage of each ingredient that was added to the mixer.
cLL is SweetLac (SweetLac 63; Westway Feed Products, Tomball, TX).
dM = Sugar cane molasses.
eVTM = vitamin and trace mineral premix, which provide per kilogram premix: 725,747 IU vitamin A, 136,078 IU vitamin D, 3,629 IU vitamin E, 91 mg vitamin K, 3 mg B12, 2,722 mg Niacin, 1,814 mg pantothenic acid, 454 mg riboflavin, 18 mg biotin, 91 mg folic acid, 181 mg pyridoxine, 3,005ppm Zn phase 1, 1,925 ppm Zn phase 2, 125 ppm Zn phase 3, 125ppm Fe, 22 ppm Mg, 15ppm Cu, 0.6 ppm I, 0.3 ppm Se.
fRONOZYME HiPhos 2,700 provided 443 phytase units (FYT)/kg with a release of 0.05 % available P.
gThe calculated nutrient composition is estimated on the diets after pelleting with 90% DM.
