When I used that before the smell coming off the food was incredible. The rats had an odor to them. I found out one of their main plants is in Georgia and they get the fat from chicken parts. Once I went back to regular food the smelled ceased.
I have been feeding southern State Sow cube for sometime and have never had problems. Even if you just mixed it 50/50 with Maz it would save you tons of money. I paid 11.50 for 50 lbs last week.
