Hi Cecile:
Did you check out the links to all the articles on the first page of this thread? Here’s an article with more info on feeding large and giant breed puppies with references posted at the end that could help with your research.

Keep in mind the commercial foods you have access to are more than likely different from those available in the U.S. Looks like the Eukanuba is a better choice out of those two kibbles.
I can’t comment on the milk powder and chic liver mix other than maybe the milk powder would throw the calcium ratio off; IDK if it’s beneficial to feed or not. Hopefully someone else will pop in with more knowledge. Any extra foods should be kept at no more than 10% of his daily caloric intake to avoid nutritional imbalance.
If you are interested in more home cooked dog food recipes for your other dogs I can post the names of some books.
