I'm not familiar with that brand as its likely US and I'm in Canada I use Tollden farms. If its anything like that then yes. Ground meat bones and organs.  
The supplement I use are AOR probiotic 3 and AOR DPPzyme.  
I deal with a very well respected and publishe holistic vet who advised to stick to poultry rabbit or lamb. He said the game meats have often proven too rich for the dogs system and many dogs have had allergy issues with beef.  
I hope that helps. PM me if I can help you out further.  
The brand of curcugen is Genestra     |
