Recipes without lamb

We have a few allergies, but he can tolerate poultry and fish at least. There are several recipes featuring these, but they often include lamb’s liver. Would it be possible to suggest a type of liver that could replace lamb?

• Do you know if he can tolerate beef? It’s the best nutritional substitute; they’re quite similar in nutritional content 😊
• Unfortunately, he’s developed an allergy. He tolerates alpaca (which is easy for me to get hold of) and game – could any of these be used as a substitute? He doesn’t eat homemade food every day, but a few days a week alongside a complete raw diet.
• I see, so it’s fine to replace it with alpaca and game 😊 If it were homemade every day, I’d adjust the plan, but since you’re combining it with complete raw food, it’s absolutely fine!
