| What do you have to do to make a valid comparison between various types and brands of dog food? |
|
Definition
The guaranteed analysis numbers represent the nutrient amounts that are present on an "as fed" (AF)
basis, which does not account for the amount of moisture that is present.AF numbers must be converted to
"dry matter" (DM) percentages, which represent the actual level of nutrients consumed with a
particular diet. AAFCO recommendations are also reported by using DM data |

Term
formula to convert AF (as fed) numbers into DM (dry matter) values. The formula calculates the
percentage of a nutrient on an AF basis with the proportion of DM in the diet |
|
Definition
1. Calculate the proportion of DM in the diet.
Bow Wow Semi Moist Cool K9 Dry
100-25% moisture = 75% DM 100-10% moisture = 90% DM
2. Use the formula to convert AF to DM.
Bow Wow Semi Moist Cool K9 Dry
22% protein/75% DM = 0.293 22% protein/90% DM = 90% DM
3. Multiply the answers by 100 to get a percentage of the nutrient on a DM basis.
Bow Wow Semi Moist Cool K9 Dry
= 29.3% protein = 24.4% protein
The conclusion is that Bow Wow Semi Moist contains more protein than Cool K9 Dry. |

calculate a rough estimate of a food's caloric distribution by using
information from the guaranteed analysi |
|
Definition
The following steps show how to calculate caloric
distribution in the guaranteed analysis of Happy Tail Dog Food.
Crude protein = not less than 28%
Crude fat = not less than 16%
Crude fiber = not more than 3%
Calculate the total calories in 100 grams of food.
Protein = 3.5 kcal/g
Fat = 8.5 kcal/g
Carbohydrate = 3.5 kcal/g
Therefore:
Protein 3.5kcal/g x 28g = 98 kcal
Fat 8.5kcal/g x 16g = 136 kcal
Carbohydrate 3.5kcal/g x 46g = 161 kcal

PM]
Total = 395 kcal
100g - 28g protein - 16g fat - 3g fiber - 7g minerals = 46g carbohydrate |

| Calculate the percentage of metabolizable energy. |
|
Definition
Calculate the percentage of metabolizable energy.
Protein ( 98kcal/395kcal) x 100=24.8%
Fat (136kcal/395kcal) x 100=34.4%
Carbohydrate: (161kcal/395kcal) x 100=40.7% |
|
|
Term
| Once we know the energy density and caloric distribution, how do we determine the amount of a particular food to give a dog? |
|
Definition
Pet food companies always overestimate the amount to feed on
their labels. A starting point is to simply reduce the amount recommended on the label by 25%.
Any further increases or decreases in the amount of food can be based on your dog's health and
weight. |
|
|
Term
| Is the source of the ingredients important? |
|
Definition
If canned foods list animal source products first or second on the ingredient list, you can assume
that the food has animal products as its major protein source. The same is true for dry foods
that list animal products in the first three ingredients. If the dog food meets or exceeds your
dog's requirement for nutrients, the source of the ingredients is immaterial. Dogs can thrive on
totally synthetic or vegetarian diets if they are properly balanced. The only time the exact source
of a food's ingredients matter is when dealing with food allergies. |

|
Term
| In the 3 important points of the AAFCO statement, what do the terms complete and balanced mean? |
|
Definition
The term "complete" implies that the dog food contains all of the required nutrients
for the canine health. If those nutrients are present in the proper amounts and
ratios, the food can be called "balanced." |

Term
| In the 3 important points of the AAFCO statement, what life stages are recognized? |
|
Definition
| Only three life stages are recognized by AAFCO: adult, growth, and reproduction. |

Term
| In the 3 important points of the AAFCO statement, what two methods are allowed for supporting claims? |
|
Definition
AAFCO regulations allow only one of two methods for supporting the claim that
a food is complete and balanced for a particular life stage.

1. Analysis using laboratory or computer-based models.
2. Using feeding protocols.
Analysis of a food's performance by feeding protocols involves giving the food to living
dogs under specific conditions. Therefore, it provides a more biological evaluation of a
product than laboratory or computer methods. |
