Talk:Colostrum
From Wikipedia, the free encyclopedia

Possible correction needed: I believe that in humans, the only immunoglobulins in colostrum are IgG, IgA, and IgM (as per http://classes.ansci.uiuc.edu/ansc438/Motherneonate/immunoglobulintransport.html). Can anyone confirm which antibodies are in fact transmitted in the colostrum? —Preceding unsigned comment added by Odd Loaf (talk • contribs) 01:55, 31 January 2008 (UTC)
[edit] From the French article
French article translation via systran:
The colostrum is the name given to the milk secreted by the mammals females at the end of the gestation and in the first days (3࠴) according to parturition.
Of yellowish color, it is very rich in essential proteins and antibodies with the immunization of the new-born baby and low in sugars. The types of antibodies met in the colostrum depend on the infectious agents to which the mother was exposed lasting her existance, either naturally, or by vaccination.
The new-born baby is able to absorb the antibodies in the first times after the birth, as long as the permeability of the intestinal cells makes it possible to let pass these large molecules. Thereafter the antibodies are destroyed during the processius digestion. This transmission cannot be done during gestation because the placenta is impermeable with the antibodies.
The new-born babies nourished with the centre are immunized thus better than those nourished with the feeding-bottle.
In the bovine breeding, one holds the name of colostrum to the product of the first draft. That collected then until the 4e day is a milk of transition whose composition approaches gradually that of the unskimmed milk. The colostrum of cow is very rich in proteins (14 % instead of 3,2 % in milk on average), in antibody (6 %), vitamin A and biogenic salts. It is also fattier (6,7 % instead of 3,2 %).
Marketed milk should not contain traces of colostrum.
The antibodies contained in the colostrum are generally specific to each species. However preparations containing of the bovine colostrum are sold like dietetic supplements with the virtues miracle in particular to resist ageing.

I removed a pretty sizable chunk of newly added material:
- (The milk of each mammal contains different components in different ratios according to what is best suited for that mammal's digestive system and unique needs...why protein, which is easily and quickly digested by humans, is responsible for the soft curds in a breastfed baby's stools. Cow's milk (and infant formula) is about 80 percent casein protein, which is good for calves' multi-stomach digestive system, but harder for human babies to digest. In early lactation, the ratio of whey protein to casein protein in human milk is about 90:10. By six weeks it is about 80:20; by six months, 60:40.(Breastfeeding Answer Book, p 21))
Most of this doesn't concern colostrum; it is describing breast milk in general. Joyous | Talk 20:27, 7 December 2005 (UTC)

"Colostrum is high in carbohydrates, protein and antibodies, and low in fat, which human newborns may find difficult to digest."
This is incorrect. Colostrum is easy to digest and that is why it is produced as the first milk.
Bear in mind that there is a societal bias against breastfeeding and this can affect information given on the subject.

- I think you are misreading the statement. It's not saying colostrum is difficult to digest. It is stating that newborns may find fats difficult to digest, and colostrum is low in fat. Joyous! | Talk 14:12, 23 March 2007 (UTC)
OK, I "misread" this too, and why I came to discuss it. I think it needs re-wording. The comma after carbohydrates and after fat are acting as brackets.
This source says that human colostrum has less carbohydrate than milk, which would be consistent with bovine colostrum (check the labels for milk and colostrum from Organic Pastures products). -- maurile, 9 September 2007 —Preceding unsigned comment added by 67.52.152.225 (talk) 17:50, 10 September 2007 (UTC)
[edit] Colostrum
You have a lot of information on the human colostrum but what about the ruminant colostrum?
In the ruminants the colostrum is important to get all the anti-bodies and the micro-organisms for the rumen to start to develop. Without this first milk after the first few hours of being born the animal will not survive.
