I just checked the pack of Hill's Science and this is what it said:
INGREDIENTS: cereals, meat and animal derivatives, oils and fats, deviratives of vegetable origin, vegetable protein extracts, minerals, eggs and egg derivatives, seeds, L-tryptophan, L-lysine hydrochloride.
AVERAGE ANALYSIS: Protein 27.8%, fat 18.5%, fibre 2.5%, ash 6.9%, calcium 1.29%
PER KG: Vitamin A 9, 100 IU, Vitamin D3 530 IU, Vitamin E 600 mg. Copper (copper sulphate) 12.3 mg. With natural preservatives (citric acid) and natural antioxidants (mixed tocopherols.)
This is all the nutritional information on here. Can anybody point out the good and bad things that are in here?
