Formulation and calculated composition of the basal diet (as-fed basis).
| Ingredient | Content (%) | Calculated composition | Nutrient levels (%) |
|---|---|---|---|
| Corn | 67 | ME (MJ/kg) | 11.44 |
| Soybean meal | 22.28 | CP (%) | 16.50 |
| Limestone | 8.72 | Lys (%) | 0.83 |
| CaHCO3 | 1.00 | Met+- +Cys (%) | 0.57 |
| Premix1 | 1.00 | Ca (%) | 3.61 |
| Total | 100.00 | Available P (%) | 0.36 |
The premix provided the following per kg of the diet: vitamin A (transretinyl acetare), 7,500 IU; vitamin B1 (thiamine mononitrate), 2 mg; Vitamin B2, 4.98 mg; Vitamin B6 (pyridoxine hydrochloride), 4.98 mg; Vitamin B12 (cobalamine), 0.02 mg; vitamin D3 (D-activated animal sterol), 3 000 IU; vitamin E (all-rac-α-tocopherol acetate), 20 IU; vitamin K3 (menadione dimethylpyrimidinol bisulfite), 2 mg; nicotinic acid, 30 mg; pantothenic acid, 15 mg; folic acid, 0.8 mg; biotin, 0.2 mg; Fe (from ferrous sulfate), 75 mg; Cu (from copper sulfate), 10 mg; Se (from sodium selenite), 0.3 mg; Zn (from zinc sulfate), 70 mg; Mn (from manganese sulfate), 60 mg; I (from potassium iodide), 1 mg; Ca, 1 g; NaCl, 3.5 g.
The experimental diet was the same basal diet supplemented with 0.5, 0.75, 1.0 g of EO-PGS/kg of the basal diet.
