Hi crazy4cats –
Feeding a variety of red meat, poultry and fish (or if not feeding fish, supplementing with quality fish oil) is very important. Different meats have different amino acid profiles, it’s important to feed a variety so your dog gets a full spectrum of amino acids. Even two different types of poultry – say, chicken versus turkey – will have completely different amino acid profiles. Rotating for this reason isn’t quite as critical when feeding balanced commercial kibble or canned foods as it would be with feeding a home cooked or raw diet as commercial diets should be formulated to include adequate levels of essential amino acids, but it’s still important. Different meats also contain different types of fat: poultry is high in polyunsaturated fats (especially linoleic acid) and low in saturated fats and docosahexaenoic acid (DHA), ruminants are high in saturated fats and low in polyunsaturated fats and DHA and fish is, typically, rich in DHA. Feeding your dogs a variety of different protein sources will help balance the fats in their diet. It’s important that dogs (and cats) consume a balanced spectrum of fats, in order to do this they will need to consume a variety of red meats and poultry supplemented with fatty fish or fish oil or it will be necessary to balance the fats in their food – this would involve supplementing red meat recipes with alpha linolenic acid (ALA), Linoleic Acid (LA) and DHA (walnut oil or hemp oil or canola oil in addition to a fatty fish or fish oil) and supplementing poultry recipes with ALA and DHA (chia seeds or flax and fish or fish oil). I don’t know of any kibble or canned food manufacturer that balances the fats in their foods so it’s best to feed a variety. I personally prefer single protein group foods – red meat, poultry, fish but a food that contains both poultry and red meat would be better than only feeding poultry based foods or only feeding red meat based foods. When I fed kibble I’d cycle between a red meat based food, then a poultry based food then a fish based food. Red meat would be beef, lamb, venison, bison, pork, etc. Poultry would be chicken, turkey, duck, etc. In addition to the reasons stated, I like red meat (for my homemade raw diets) because I have a greater variety of organ meat to choose from. When feeding poultry the only option is liver (gizzards and hearts count as muscle meat), this isn’t enough variety. So I typically feed red meat organs because I can get liver, kidney, lungs, spleen, pancreas – I can also get healthy “by-products” such as trachea, gullet and green tripe.
