Starter and grower diets contained an anticoccidiostatic drug (Maxiban, 0.375 g/kg; on top).
The premix supplied per kg diet: Ca, 3 g, Cl, 0.01 g, vitamin A, 12,000 IU, vitamin D3, 4,000 IU, vitamin K3, 3.33 mg, biotin, 250 μg, folic acid, 1.67 mg, vitamin B1, 3.33 mg, vitamin B2, 8 mg, Vitamin B6, 4.17 mg, vitamin B12, 25 μg, nicotinamide, 69.1 mg, calcium pantothenate, 20 mg, choline chloride, 400 mg, Fe, 50 mg, Cu, 15 mg, Mn, 100 mg, Zn, 70 mg, I, 1.56 mg, Se, 0.25 mg. Vitamin E was omitted in the premix.
Values show calculated values based on AMINODat 5.0, and values in brackets are analyzed values. SID = standardized ileal digestible. Analyzed SID amino acids were calculated from analyzed amino acid concentrations with the help of amino acid digestibility values from AMINODat 5.0. The metabolizable energy (ME) content of the diet was calculated based on crude nutrient analyses of the dietary ingredients or for values in brackets of diets, according to GfE (Gesellschaft für Ernährungsphysiologie) (1999).
