Different Country, different food?

Curiosity on labelling - was messing around with something and noticed ambiguity in labelling - bag of Royal Canin Mini has ingredients listed for 24 countries including EU, Australia, South Africa Korea Russia etc but in the English list - for GB/IRL/RSA/AUS the analytical content is labelled differently for RSA and shows different numbers.
So decided to look up on t’internet - the only web site mentioned on the pack is www.royalcanin.com
Royal Canin Mini Adult ingredients
Chicken meal, brewers rice, brown rice, corn, corn gluten meal, chicken fat, natural flavors, wheat gluten, dried beet pulp, vegetable oil, brewers dried yeast, fish oil, potassium chloride, calcium carbonate, salt, fructooligosaccharides, sodium tripolyphosphate, DL-methionine, choline chloride, L-lysine, magnesium oxide, vitamins [DL-alpha tocopherol acetate (source of vitamin E), L-ascorbyl-2-polyphosphate (source of vitamin C), biotin, D-calcium pantothenate, pyridoxine hydrochloride (vitamin B6), vitamin A acetate, niacin supplement, thiamine mononitrate (vitamin B1), riboflavin supplement (vitamin B2), folic acid, vitamin B12 supplement, vitamin D3 supplement], taurine, trace minerals (zinc oxide, zinc proteinate, ferrous sulfate, manganese proteinate, copper sulfate, copper proteinate, manganous oxide, calcium iodate, sodium selenite), L-carnitine, rosemary extract, preserved with natural mixed tocopherols and citric acid.

But if you go on the www.royalcanin.co.uk website the ingredients are list like this

to me that’s two totally different foods - only seeing this as a problem because the writing on the packaging is tiny and the logical thing to find bigger type face would be to visit the website listed on the packet. Also why such a difference in the US food and the other 24 countries? - yikes just looked into it further - the US one is double the price of UK per kilo (if my maths and conversion is right)
Does anyone know of any other foods that differ so much between countries?
