The energy requirements for carbohydrates increase in dogs during pregnancy. Because cats are strict carnivores, they don’t have a dietary requirement for carbohydrates and cannot metabolize large amounts of simple carbohydrates. It bulks up food – more bulk/fiber It reduces cost – in the manufacturing process, CHO less expensive than fat or protein.
Normalize bowel transit time is IMPORTANT because fiber pulls water into the bowel and softens it for passage. If an animal has diarrhea, the fiber absorbs the excess water. Probiotics help to establish the best balance of microorganisms in the GI tract. They live in the colon and break down long chain insoluble carbohydrates into healthy short-chain fatty acids. They nourish colonic cells.
Cats lose taurine in their feces due to normal GI bacterial action, and coupled with the fact that they can’t synthesize it, makes it an important essential amino acid. Tell story of litter of kittens and vegetarian owner at ASPCA. Importance of Taurine.
AAFCO doesn’t publish ranges in its profiles – only minimums of nutrients and in the case of certain minerals like calcium and phosphorus – maximums.
Alpha linolenic , Linoleic acid and Arachaonic acid are all ESSENTIAL FATTY ACIDS. DOGS: Linoleic is essential in the dog, and from that dogs can make alpha linolenic. Dogs can also synthesize arachidonic acid CATS: Arachidonic is essential in the cat only – they cannot synthesize it. Omega-6 fatty acids are required for growth and reproduction, and are precursors to certain hormones – like prostaglandin CELL MEMBRANE: remember from your anatomy class that the cell membrane is made up of a phospholipid bi-layer
Ben was a patient at the Animal Referral Center in Ft. Pierce, Florida.
This is a radiograph taken of Ben’s pelvis prior to surgery. You can see cardinal signs of hip dysplasia here. The left femur head doesn’t fit into the acetabulum, and has worn away some.
This is a post-surgery radiograph – Ben had his left femur head removed – a femoral head ostectomy. The point of all this is to illustrate the connection between obesity and skeletal problems.
