Rat breeding project part Two

How can I make my rats grow faster what food can make them grow bigger yet remain healthy?

I feed mine their block, then daily table scraps, stale bread etc.

This mix is good too:

I used it for a while. I'll specifically give it to nursing mothers to get their weight back on.

I use vanilla Ensure to plump up any moms that get thin. I suppose I could give it to feeders that are growing or just before I feed them off(a few days before).

I just soak Mazuri lab block in the Ensure and then feed the mush to the rats. They love it.

I feed Purina Mills Sow and Pig food, Garden Rotini pasta (dry) and they get fresh veggies from time to time. If I notice a rat needs to gain a bit, I also feed them a little hardboiled egg. I plan on making a dry mix of puffed grains, oatmeal, and garden rotini to feed along with their pig feed. At some point I might switch to Mazuri 6F or do a combination of the Mazuri and pig feed. Not sure yet, but what I feed now keeps them pretty healthy. One of our breeder males got around 525g before we sold him as a pet.

I use a similar mix to the link posted, minus the dog food. I feed 18% protein lab blocks to all my rats. I also feed this dry mix to moms / pups, but it could be feed to others as well:
Whole wheat dry pasta or veggie pasta
old fashioned oats
black oil sunflower seeds
freeze-dried meal worms (usually sold to feed pond fish)
rat and mouse natural carnival diet by hm brown ("natural" has no pellets in it, which they don't eat anyway)

I also feed moms / babies a daily helping of veggies and boiled egg including kale, carrots, cucumber or zucchini, sometimes other greens as well. My adults get this 2-3 times a week as a treat, the same with the seed mix above.

I also sometimes give them soy milk, but some do not take to it. I may try soaking the lab blocks in it and see what they think.
