This is what I used to feed when I fed lab blocks. I have since changed over to low quality dog food. It has almsot the exact same nurtitonal values as Mazuri, with *slightly* higher fat/protein content, which I find supports breeding females much better than the lab diets did, as well as produces quicker growing, plumper feeders, which is exactly what you want in feeder rodents
