The Composition of "First Milk" Bovine Colostrum
IMAGE
The biologically active components in bovine colostrum change very rapidly after the calf is born. Due to these rapid changes, it becomes necessary to know that it has the highest amount of biologically active substances and that you know exactly what makes up bovine colostrum.
Protein.
Most of the biologically active substances in complete bovine colostrum that can convey significant health benefits are proteins. Since almost all of the beneficial proteins are conveyed from the mother's bloodstream into the colostrum before birth and the mother then begins to reabsorb them about 6-8 hours after birth, it is important to use colostrum that has been collected during a time period that will minimize the effect of the reabsorption process. Of real significance is the fact that by 24 hours after birth most of the proteins in the udder fluid can be accounted for by two individual proteins that are primarily only of nutritional value, casein and albumin.
Colostral Fat
Although some people disagree, the milk fat in the ?first milking? is very important and also contains the necessary protein, casein. Some companies choose to remove the milk fat from their colostrum claiming it deteriorates their product faster and doesn't have any purpose They claim the substitute fat they add is more digestible. On the contrary, the casein found in the milk fat of true colostrum serves a very important purpose. In the stomach it breaks down into absorbable peptides and amino acids. These peptides and amino acids create a cottage cheese-like curd that is used to create new muscle protein in the stomach. The ?first milk? colostrum contains that important protein, casein, as well as other significant biologically active substances and should be left in the colostrum product.
20-30% of the ?first milking? colostrum is milk fat. Some beneficial biologically active substances found in that milk fat are corticosteroids, steroid hormones, some growth factors, vitamins A, D, E and K and insulin.
Lactose (milk sugar).
10-15% of the ?first milking? colostrum is lactose. An enzyme in the calf's stomach and saliva, called the lactase enzyme, break glucose and galactose down to create energy for the developing calf. The amount of lactose increases in the mother's milk for the developing calf. The lactose content 6 hours after birth is half of what it is at 12 hours and a third of what it is 24 hours after birth.
Since most people have the same enzyme (lactase) in their saliva and their digestive system, the lactose in the colostrum that they use as a dietary supplement can provide the same ready source of metabolic energy. However, there are ?lactose intolerant? individuals who have problems digesting lactose because their body produces too little or none of the lactase enzyme. The amount of lactose in first milking colostrum collected within 6 hours after birth is about one-half of what it is at 12 hours after birth and one-third of what it becomes by 24 hours. Therefore, a high quality complete first milking colostrum collected within 6 hours after birth can be used as a dietary supplement by more people without potentially having them suffer the discomforts associated with lactose intolerance.
More Compositional Considerations
The following comparative facts about colostrum and milk further stress the value of a complete first milking colostrum in maximizing the health related benefits.
Colostrum has 10 times the amount of vitamin A than milk.
Vitamin D is found to be 10 times greater in colostrum than milk.
Colostrum has 10 times the amount of iron than milk
Colostrum has more magnesium, phosphorous and calcium than milk.
Biologically Active Components
Metabolic Factors, Growth Factors and Immune Factors are the major categories bovine colostrum can be divided into. When looking into bovine colostrum, be aware of companies' interpretations of what these components do rather than what the original studies show. - 17269
