ik voer op het moment alleen gemalen kippenvleugels als calciumbron.nou las ik dit op internet:

From the above example one can see that whole commercially available chickens without innards may contain too much bones vs. meat to be fed longterm as a sole dietary source to cats (2 parts meat vs. 1 part bones), but clearly, wings (necks) and backs are definitely way too rich in bones and should only be fed as a supplement to lean meat. Meyer/Zentek say that 1 g of bones per 1 kg of body weight suffice to cover maintenance requirements for calcium and phosphorus but should not exceed 10 g per day per kilo body weight. Note that approx. 70% of the dry, fat-free mature bone are minerals (generally known as bone ash) of which the chief components are 80% Ca3(PO4) = calcium phosphate, 13% CaCO3 = calcium carbonate and 2% Mg(PO4) = magnesium phosphate and the remainder 5% will be small amounts of other macro minerals and trace minerals. The remaining 30% of bone (dry, fat-free) is the organic fraction, over 90% of which is collagen which has low digestibility and is (to some extent) subject to bacterial fermentation in the colon.
een kippenvleugel zou dus te veel bot bevatten?
moet ik dan gewoon wat minder geven?
normaal krijgen ze zo'n 100 gr gemalen kippenvleugel per dag.(ze eten zo'n 1400 gr per week,waarvan 700 gr dus kippenvleugel.is dit dan te veel?
ik ben nog op zoek naar andere soorten bot,en dan iets wat ik ook met mn hand-gehakt-molen kan malen...iemand ideen?
