The Frankenprey diet is designed to mimic eating Whole Prey.
If they are eating Frankenprey, they are receiving everything that they need.
The Frankenprey diet is:
7-9 meals of Bone In meats
3-4 meals of Muscle meats, one of which is Heart.
1 meal of Liver plus another Organ
1 meal of Liver plus another Organ plus a half meal of Heart.
Bones provide:
Calcium, vitamin D, phosphorous, magnesium and protein. Calcium is particularly important for bone development.
The Bones that a ferret eats are those of an animal the size of a chicken or smaller.
Chicken wings, Cornish game hens, Quail, rabbit, mice or Guinea Pig are some examples.
Heart provides most of the Taurine needed for Ferrets.
Taurine is essential for Ferrets: It is essential for cardiovascular function, and development and function of skeletal muscle, the retina, and the central nervous system.
Heart is ten percent of their weekly menu.
Taurine is also found in smaller amounts in animals, but for our purposes we use Heart to ensure an adequate amount. Tongue contains alot of Taurine and can be substituted for Heart, when Hearts are hard to find.
Liver: Animal livers are rich in iron, copper and preformed vitamin A.
Liver can build up in a Ferret's system, unlike Taurine which is water soluable.
For that reason, their weekly menu is limited to two Liver meals and another Organ. Liver is ten percent of their weekly intake.
On Frankenprey, ferrets get Liver plus another Organ that secretes:
Kidney, spleen, thymus, pancreas or brains.
These organs offer some of the densest sources of nutrients like B vitamins, iron, phosphorus, copper and magnesium, and are rich with the most important fat-soluble vitamins, A, D, E and K.
On the Frankenprey menu, they eat a minimum of three proteins.
Beef is high in Iron and Vitamin B
Turkey, Pork, Lamb, Goat are some good protein sources and each provides nutrients that are important such as Choline. Choline is important for the central nervous system and is part of the Vitamin B group.
Fat equals energy for Ferrets and fatty cuts of meat are good choices.
Additionally, a raw egg a week and fish oil will provide plenty of Omega 3's.
If you are feeding Frankenprey and following the correct guidelines, your ferrets should not need additional supplements.
As for Probiotics, I haven't needed to use them. I'm tagging
Heather to help you with that question.
I tried to look up the ingredients in your products and couldn't find a definitive list of what is in Pet Friends Animinierals. I did find one site that gave me an idea of what was in the product and there seemed to be alot of Liver.
