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.

Ingredients (what's this?)

The table below indicates the primary ingredients for the lot number indicated.

Primary ingredients

Dried whole goat milk, vegetable oil, calcium sodium caseinate, soy oil, whey protein concentrate

Secondary ingredients Dicalcium phosphate, L-arginine, DL-methionine, choline chloride, potassium chloride, calcium carbonate, potassium phosphate monobasic, magnesium carbonate, salt, potassium phosphate dibasic, magnesium sulfate, zinc sulfate, vitamin A supplement, ferrous sulfate, vitamin B12 supplement, calcium pantothenate, copper sulfate, ascorbic acid, niacinamide, manganese sulfate, folic acid, riboflavin, vitamin D3 supplement, thiamine hydrochloride, potassium iodide, pyridoxine hydrochloride, potassium citrate, vitamin E supplement, biotin.


Solubility Test (what's this?)

As shown below, considerable separation occurred with this product after 30 minutes. While hotter water and longer hydration time showed improvements, the product never seemed to fully reconstitute.

Figure 1. This product produced separation into 3 distinct layers as shown above. The top level was unwetted powder. The middle layer was translucent that appeared to be liquefied oil. The bottom layer appeared to be dilute formula solution. As shown, the formaul was better with hotter water and longer hydration time. Figure 2. A considerable amount of residue was observed at both water temperatures and both hydration times.


Physical characteristics

The texture of this product was very 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)).


Weight/TBSP and measurement variability

Weight (average) 6.0 grams / TBSP (large end of red scoop).
Texture and handling comments Somewhat clumpy in texture, scoops somewhat unevenly and inconsistently.
Observed measurement variability (what's this?) Scooping error generally within +/- 2.7%.

Low error -5.0%; High error +3.3%.

Scoop or weigh? Weighing this product (rather than scooping) will produce a more accurate measurement.
