Star Milling Co. lab block- Reviews?

Hi all,
I bought rat chow from this milling co at my local feed store (they didn't have any known brands :/ ) and I'm just wondering how it stacks up. I accidentally tore off the top of the label when I she-hulked the impossible-to-open double walled bag, so I don't have the exact name of the food. I checked out their website, but that wasn't very helpful. If it helps, the bottom of the label says code: 05/06. When I ordered it, I want to say the clerk said it was called Fat Rat. My rats seem to be doing well on it, no cannabalism or anything, I just have a little bit of greasiness on my females. I'd appreciate any input y'all have on this brand of food.

You ever learn anything about it?

Star Milling Company is down the street from me. I have had to use it in a pinch when Mazuri didn't arrive. On the Star Milling stuff my output dropped to 5-7 babies on experienced moms. I also noticed a few moms that delivered stillborns (undeveloped).... I am faithful to Mazuri because my rats are healthier and production is back at around an average of 14 but I have had 2-21 litters 1-22 litter and 1-23 litter. The star is about 21.00 a bag. I pay 30.00 for my Mazuri. There is 0 thought involved in this.
