Proximate Analysis, Minerals and Calories (click here for Midwest Lab report )

The table below indicates the values for test results from Midwest Labs, plus calculated values for components in a formula mixed at a ratio of 1:2 with water using WildAgain's nutrition calculator. The Kcals are calculated using both the standard Atwater calculation as well as the modified Atwater as prescribed by AAFCO.

Protein %	41.7	Protein %	6.6
Acid Hydrolysis Fat %	27.1	Fat %	4.3
Carbs (subtraction) %	18.4	Carbs %	2.9
Calcium %	2.09	Calcium %	.3
Phosphorus %	1.74	Phosphorus %	.3
Magnesium %	.106	Ca/P Ratio	1.2
Sodium %	.46	Kcals/cc (Atwater)	.81
Potassium %	1.62	Kcals/cc (AAFCO)	.73
Peroxide Value (what's this?)	11.1

Solubility Test (what's this?)

The instructions on the KMR® packaging indicates that this powdered milk replacer can be used immediately after mixing. It states... "Gently shake or stir one part powdered KMR® into two parts warm water." When mixed following these instructions (using hot tap water at 125°F), the formula produces an unwetted cap of undissolved powder that comprises 18% of the volume of the mixing container after 30 minutes. The photo of the cylinder on the far right shows this unwetted cap (flotation line is evident a line marker 82.) The use of hotter water (175°F) improves the formula, but still produces an unwetted cap of 13% volume (as shown below). Allowing the formula to rehydrate in the refrigerator (40°F) for 4 hours improves the solubility even further, but still produces an unwetted cap of undissolved formula at line marker 94. The photo above on the right (Figure 2) shows the amount of residue remaining after emptying the cylinders after 30 minutes.


Figure 1. This lot did not fully rehydrate when used as an instant mix or after rehydrating for 4 hours. Using hotter water (175°F) did reduce the amount of wetted product for immediate use, but had no effect after 4 hours.	Figure 2. This lot did produce considerable residue at both immediate use and after 4 hours. Using hotter water (175°F) did reduce the amount of residue for the immediate mix, but had no visible effect after 4 hours.

Physical characteristics

The texture of this product was uneven and inconsistent. This resulted in measurement error described below. (The expected error shown below is equal to 1 standard deviation (statistically 68% of all measurements should fall within this range)).

Texture	Weight/TBSP and measurement variability
Photo not available for this lot.	Weight (average)	5.9 grams / TBSP (large end of red scoop).
	Texture and handling comments	Clumpy, scoops unevenly and inconsistently.
	Observed measurement variability (what's this?)	Scooping error generally within +/- 5.0%. Low error -11.9%; High error +6.8%.
	Scoop or weigh?	Weighing (rather than scooping) will produce a more accurate measurement.
