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
The milk fat in complete first milking colostrum is one the most under-rated and misunderstood components by many companies that promote bovine colostrum for human consumption. There are all kinds of stories, none of which are ever substantiated with any scientific evidence that the fat in colostrum doesn't serve any purpose and/or that having it there leads to faster deterioration of the product. Nothing could be further from the truth. In fact, one of the companies that removes the fat from what they call "colostrum" then adds a component of the fat back to their dried products. They claim that this makes their "colostrum" more digestible, which was one of the functions of the fat in complete colostrum in the first place. Casein is a nutritionally valuable complete protein that is broken down in the stomach to small peptides and amino acids so that they can be absorbed and used to build new muscle protein by forming a cottage cheese-like curd in the stomach. This occurs enzymatically in the newborn and the adult and the basis for the curd that forms is the fat in the colostrum. So without it, in addition to losing some significant biologically active substances that are associated with the fat, one loses most of the nutritional value of the casein. That is part of the reason why the fat content of colostrum increases with time after birth as the amount of casein increases in the secreted fluid. Mother nature doesn't waste much and has organized the components of colostrum and their changing pattern in an efficient way to maximize the benefits to the offspring that is going to receive it.
Bovine colostrum contains 20-30% milk fat. Insulin, some growth factors, corticosteroids, steroid hormones, and vitamins A, D, E and K are some of the beneficial biologically active substances found in the milk fat of bovine colostrum.
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.
The metabolic energy that comes from lactose being broken down from the lactase enzyme in the saliva and stomach can also benefit humans. For those people who are lactose intolerant, their bodies struggle to digest lactose because their bodies have little or don't have the lactase enzyme. Most of these people can use bovine colostrum as a dietary supplement without having to worry about it causing them discomfort due to their lactose intolerance.
Other compositional considerations.
When colostrum and milk are compared, the following results are found:
Vitamin A is found to be 10 times greater in colostrum than milk.
Colostrum has 3 times the amount of vitamin D than milk
Colostrum contains at least 10 times more iron than milk.
Colostrum contains more calcium, phosphorous and magnesium than milk.
Biologically Active Components
The ?first milking? colostrum biologically active components can usually be divided into categories. Most components fit into these basic categories: Growth Factors, Immune Factors and Metabolic Factors. Sometimes different suppliers of colostrum will give claims of their interpretation of results found in studies rather than the facts found by the scientific investigator. It is important to keep that in mind as you examine different colostrum suppliers. - 17274
