Just read the latest posts... chromium picolinate in cat food? ha ha ha ha ha ha ha That's right what someone said above: its probably there to counter the high amount of carbs in the diet. As I said, the "Complete and Balanced" banner on the petfood label is a myth. I'd rather eat food prepared in the average kitchen than in the petfood manufacturer's laboratory.
It's like modern medicine: take this pill to get rid of your headache. Oh, BTW, the pill will make you slightly nauseous. To counter that, I have here an anti-nausea pill, which BTW, may produce loose BM. To counter that, I am prescribing this 3rd pill which may or may not give you heart palpitations.... just in case they do, I'm giving you a 4th pill... which may kill you if you do not take it exactly as prescribed....
No thanks, doc, I think I'll bear with the headache and see if an icepack in my old fridge would do the trick.
And... no thanks, PFI: I'll make Cato's food and my own.

Your not kidding. When my dad started up on medications, originally for high blood pressure he started slowly going downhill and they kept prescribing more and more med's for all these "ailments" that started appearing out of no where. My dad died in Jan 08 and I still believe it was the medications that caused his neurological system and health to fail not "Alzheimer symptoms" that supposedly took his life. He went from healthy to a basket case in 5 years when he started these meds up. |

What struck me about the numbers is the dry dog food tests show 5-10x the recommended amount of ALL supplements in it, for all formulas. You have to wonder why they would waste that money on oversupplementation, unless it's to make up for poor food quality.

Petslave, what I can't get my mind around is that this is AFTER processing results. Are these macro nutrients/minerals diminished by processing?
If a substantial portion of nutrients are lost during processing & this is the level of what's left.. I can't picture how they have "room" for the "food" part. Shoot, I have an image of living off of vitamin pills without eating " food ".

That's exactly right. Most of the nutrients are processed out or rendered into something noxious. Macro and micro nutrients have to be put back in after processing through high heat torts. Your pet is basicaly eating rag cloth spiked with vitamins and minerals, most of which are not natural but made in the laboratory. Boggles the mind to think of it. |

Would some math pros help me here, pretty please? I'm seriously mathematically challenged  On an average we feed 3/4 cup kibble daily split between 2 meals. It weighs 110 grams per cup, 1/8 cup is 13.75 grams of unground kibble, so that's 82.5 grams of food ( 6 X (13.75g in 1/8 cup)). Don't know if it matters, but the moisture is 10% on the label. (3/4 cup of unground kibble is approx 3.045 ounces ? without water adjustment.) If phosphorus test results were 12,000 ug/g how much did I feed in mg so that I can compare it to the NRC 160mg? ETA: Removing 10% moisture from serving: 82.5/.90=91.67g/dm served Convert 12,000ug/g to mg= 12,000/1000=12mg/g 91.67g/dm x12=1100.04mg/dm potassium 82.5g x12 = 990mg potassium (w/o moisture adj) Am I going the right direction? |

LOL, yes you are  . If Phosphorus results were 12,000 ug/g "as received" (or "as fed"), that means the test sample contains 1.2% Phosphorus. If you fed 82.5g of a food which contains .012% Phosphorus, you fed .99g, or 990mg, of Phosphorus. Also, if your food (like the test sample) contains 1.2% Phosphorus (and we assume that it does), and it's moisture content is 10% moisture, your food contains 1.3% Phosphorus on a "dry matter basis". (OK, maybe it's not a perfect analysis, but it's close enough). 1.2% Phosphorus / (100% - 10% Moisture) = 1.3% Phosphorus expressed as "dry matter" AAFCO recommends 0.50% Phosphorus on a dry matter basis. So your food contains 2.6 times what AAFCO recommends. Guys, it's not the math - it's all those apples and oranges. 5CM |

 Taking the mystery out of finding out how much is in what you actually feed in your home is a good thing. It was hard for me to look at the test result amounts and relate that to the amount of food in my at home feeding schedule. A 12lb cat most likely isn't eating the same amount as a 9lb cat for maintenance feedings and learning how to compute the as fed nutrition to your own pet is IMO a good thing. The same math applies no matter whether it's phosphorus or calcium, or whatever in the list of test results. What it enables me to do is to take the results, calculate based on what my cats are eating & give the Vet more information when we have issues.. like Ling's weight loss and Dollywad's weight gain (even when on a diet) & persistent diarrhea to see if it give any information from that exercise helps figure out what's happening.

Offy, Thanks for writing all that out. Big help, IBL. We know that the nutrient composition of food varies, so sometimes a particular nutrient will be higher, and sometimes, lower. The expectation is that, over time, the nutrient composition will vary around the nutrient requirements by some tolerance. Will leave it to the food scientists to account for such variations, and calculate the nutrient profiles and databases. Nutritionists can help us to balance the diet in order to meet certain requirements, and the process may get a bit involved. But Offy's approach gives us a starting point, and the ability to discuss diet and health with the vet. Clearly, "one size doesn't fit all", so one recipe isn't right for everyone, but if you're interested, Marta Kaspar's Alternative Nutrition site provides a nutrient calculator. It's very cool - and it's free. http://www.knowwhatyoufeed.com/RecipeBasicnonmetric.htmhugs, 5CM =^..^ = |

There are some new test results up at Don's site, being challenged in the pet food test deciphering category...what are your thoughts on these new test results? http://www.pfpsa.org/news.html |
