PC = positive control diet; PC diet was mixed as a single batch and subdivided into the PC and PC + phytase treatments.

2

NC = negative control diet; NC diet was mixed as a single batch and subdivided into the NC and various NC + phytase treatments.

3

Vitamin–mineral premix (units per kilogram of feed): vitamin A, 12,500 IU; vitamin D3, 3,125 IU; vitamin E, 40 IU; vitamin K (menadione), 2.5 mg; riboflavin, 7.5 mg; D-pantothenic acid, 12.5 mg; vitamin B12, 0.01875 mg; pyridoxine, 5 mg; thiamine, 2.55 mg; folic acid, 0.625 mg; niacin, 37.5 mg; biotin, 0.15 mg; iodine, 1.65 mg; copper, 15 mg; iron, 80 mg; selenium, 0.3 mg; manganese, 88 mg; zinc, 100 mg.

4

Quantum Blue phytase (5,000 FTU/g of premix; AB Vista, Marlborough, UK).

5

Quantum Blue phytase was added on top of the NC diet at 0.03 (150 FTU/kg), 0.06 (300 FTU/kg), 0.12 g/kg (600 FTU/kg) or 0.24 (1,200 FTU/kg) g/kg for the NC phytase-containing diets, or on top of the PC diet at 0.24 g/kg (1,200 FTU/kg) for the PC phytase-containing diet.
