based on being formulated to meet the nutrient content of the Dog Food Nutrient
Profile for Growth and Reproduction.
Because of concerns for excess calcium to produce detrimental effects in growing
dogs of large and giant breeds, 10-13 the 2007 CNES deemed that additional restriction to
the maximum limit for calcium was warranted and lowered the maximum calcium
concentration to 1.8% DM. The CNES did not believe it necessary to decrease the
previous maximum calcium concentration of 2.5% for adult dogs or growing dogs of
small or moderate size breeds. However, the AAFCO Pet Food Committee felt that
only one maximum value should be established, especially to ensure all life stage
products were properly formulated. Thus, the AAFCO Pet Food Committee elected to
set the maximum calcium for all dog foods formulated to meet the Dog Food Nutrient
Profiles at 1.8% DM. The CNES retained the maximum phosphorus concentration of
1.6% DM for both profiles, as well as the minimum and maximum values of 1:1 and
2:1, respectively, for the calcium to phosphorus ratio.
OTHER MACROMINERALS
POTASSIUM
The 2007 CNES elected to retain the recommended minimum potassium
concentration at 0.6% DM for both Profiles. Although the RA in the 2006 NRC and
some concentrations in the FEDIAF Guidelines are less than 0.6% DM for potassium,
the CNES felt that the potassium concentration did not warrant changing especially
given that potential toxicosis of potassium was not a practical concern. Thus, a
maximum concentration for potassium was not established.
SODIUM & CHLORIDE
The 2007 CNES did not change the minimum recommendation for sodium or
chloride in the Growth and Reproduction Nutrient Profile as the values are slightly
above the 2006 NRC RA. The 2007 CNES made an editorial increase in the
recommended minimum concentrations for sodium and chloride in the Adult
Maintenance Nutrient Profile to match the 2006 NRC RA. For sodium the increase
was from 0.06% to 0.08% DM and for chloride from 0.09 to 0.12% DM. The
recommended minimum concentrations for sodium and chloride in both dog food
nutrient profiles continue to reflect the 1:1.5 sodium to chloride ratio of salt previously
used by the 1990 CNES to justify recommended chloride concentrations. As noted by
the 1990 CNES, because palatability and food consumption would decline due to
excess sodium before adverse health effects were observed, setting a maximum
concentration for sodium was not of practical concern.
MAGNESIUM
The 2007 CNES increased the minimum recommended concentration for
magnesium from 0.04 to 0.06% in Adult Maintenance and Growth and Reproduction
Nutrient Profiles to match the 2006 NRC RA for adult maintenance and peak lactation,
respectively. The 2007 CNES deleted the maximum recommended concentration for
magnesium due to lack of data specific to dogs in both the 2006 NRC and the 2005
Mineral Tolerances of Animals. The only comment regarding maximum magnesium
content in the 2006 NRC was that a SUL for magnesium in the diets of dogs was
greater than 1.7% DM.
MICROMINERALS
IRON
The 2007 CNES made an editorial change to the minimum concentration for iron
in the Growth and Reproduction Nutrient Profile to make the concentration consistent
with a presumed caloric density of 4000 kcal ME/kg DM which makes the
recommended concentration consistent with the RA from the 2006 NRC and the
