  1. aIngredients in descending order (high protein quality diets): liver, meat, wheat flour, sunflower oil, blood meal, greaves meal, minerals, gelling and thickening agents, vitamins
  2. bIngredients in descending order (low protein quality diets): liver, trachea, wheat flour, meat, sunflower oil, greaves meal, blood meal, minerals, gelling and thickening agents, vitamins
  3. cAdditional analysis of total dietary fiber (TDF) revealed that the values were below the detection limit for all experimental diets. The analyses were performed according to the instructions of the manufacturer (Total Dietary Fiber Assay Kit, Megazyme u.c., Ireland)
  4. dCalculated according to NRC [22]
