Skim Milk Powder
Skim milk powder (SMP) is a dairy product of the dairy industry that is made by evaporating milk to dryness and by removing the water from pasteurized nonfat milk. By depriving microorganisms of water (which is required for their survival and development) by drying the milk, it allows skim milk powder to have a longer shelf life, of up to 3 years if stored properly. SMP contains lactose, milk proteins and minerals in the same relative proportions as the fresh milk from which it was made. In order to remain safe, SMP needs to be stored under cool, dry conditions and protected from any contact with water during storage. SMP provides an excellent source of lactose (49 to 52%), protein (34-37%), minerals (calcium, sodium, potassium, phosphorus, iron, magnesium, and zinc), and amino acids (isoleucine, leucine, lysine, methionine, and phenylalanine) required, as well as functional properties such as water binding, thickening, emulsification and flavour.
Egg quality: When combined with a diet containing Lactobacillus acidophilus, SMP significantly improved egg quality characteristics which included higher shell thickness, specific gravity, Haugh unit, and shell percentage.
