Why are the fat and protein levels in Esbilac/KMR liquid different than in the powders?

When you read the Guaranteed Analysis on a can of liquid milk replacer and a can of powder milk replacer you are reading values for the product in that container. The guarantees for powdered milk replacers are much higher because the numbers listed are the nutrient values prior to the water being added. If you look at the values for moisture on the labels, you’ll notice that the moisture level on the can of ready-to-serve liquid is much higher than on the can of powder. Once you reconstitute the powder with water, the fat and protein levels should be similar to those shown on the label of the ready-to-use liquid.
