AAFCO制定的狗食&貓食標準

AAFCO (Association of American Feed Control Officials) 美國飼糧管理協會

下面兩個表是AAFCO在2008年發表的狗食&貓食營養標準

真沒想到貓食蛋白質&脂肪的最少需求量比狗食還多，難怪我覺得在家的寵物貓好像都很容易胖

a Presumes an energy density of 3.5 kcal ME/g DM (metabolizable energy/gram dry matter), as determined in accordance with Regulation PF9, which is based on the 'modified Atwater' values of 3.5, 8.5, and 3.5 kcal/g for protein, fat, and carbohydrate (nitrogen-free extract, NFE), respectively. Rations greater than 4.0 kcal/g should be corrected for energy density; rations less than 3.5 kcal/g should not be corrected for energy. Rations of low-energy density should not be considered adequate for growth or reproductive needs based on comparison to the Profiles alone.
^b Although a true requirement for fat per se has not been established, the minimum level was based on recognition of fat as a source of essential fatty acids, as a carrier of fat-soluble vitamins, to enhance palatability, and to supply an adequate caloric density.
^c Because of very poor bioavailability, iron from carbonate or oxide sources that are added to the diet should not be considered as components in meeting the minimum nutrient level.
^d Because of very poor bioavailability, copper from oxide sources that are added to the diet should not be considered as components in meeting the minimum nutrient level.
^e Because processing may destroy up to 90 percent of the thiamin in the diet, allowance in formulation should be made to ensure the minimum nutrient level is met after processing.

b Although a true requirement for fat per se has not been established, the minimum level was based on recognition of fat as a source of essential fatty acids, as a carrier of fat-soluble vitamins, to enhance palatability, and to supply an adequate caloric density.
c If the mean urine pH of cats fed ad libitum is not below 6.4, the risk of struvite urolithiasis increases as the magnesium content of the diet increases.
d Because of very poor bioavailability, iron from carbonate or oxide sources that are added to the diet should not be considered as components in meeting the minimum nutrient level.
e Because of very poor bioavailability, copper from oxide sources that are added to the diet should not be considered as components in meeting the minimum nutrient level.
f Add 10 IU vitamin E above minimum level per gram of fish oil per kilogram of diet.
g Vitamin K does not need to be added unless diet contains greater than 25 percent fish on a dry matter basis.
h Because processing may destroy up to 90 percent of the thiamin in the diet, allowance in formulation should be made to ensure the minimum nutrient level is met after processing.
i Biotin does not need to be added unless diet contains antimicrobial or antivitamin compounds.
j Methionine may be used to substitute for choline as a methyl donor at a rate of 3.75 parts for 1 part choline by weight when methionine exceeds 0.62 percent.
