The best is fresh tripe, i'm afraid I don't know where you could get it where you are. Here I have a good supplier for raw feeders who I order it from. However if you can't find it fresh, don't stress, dehydrated will still be good for her and its not like its an essential. The benefits are that its a natural food for them full of live digestive enzymes and probiotics and they love it! I don't go by exact amounts, just give her a small amount.
Its good to give a variety of protein sources because there are different vitamins and minerals in different meats, so feeding a variety ensures they will consume a wide range of nutrients.
If she looks fantastic and has a ton of energy then you are doing GREAT
