The Production of High Vitamin A Milk by Diet
Quote from

This is why commercial milk/dairy can be harmful. Vitamin A can be in much higher amounts than found on the label since all milking cows consume a diet that is fortified with Vitamin A. Organic dairy is not fortified with Vitamin A, which means less Vitamin A in the dairy fat. Additionally, Vitamin A seems to replace the beta carotene in the milk when it is supplemented.
To put the results into perspective, butter typically has only 25 iu Vitamin A per gram. In this study, they were able to increase the amount to 170 using shark liver oil.
Summary
The vitamin A content of the butterfat obtained from cows on a diet high in fresh alfalfa was considerably increased by the administration of shark liver oil in daily doses of approximately 700,000 I.U. although lower amounts were ineffective.
The vitamin A in butterfat averaged 113 I.U. after administration of the vitamin A supplement at a level of 1,400,000 I.U. daily. In one cow, the level reached 170 I.U. per gram which value was also noted a month later. The increased amounts of vitamin A in the butters persisted without diminution over a 5-month period during which the experiments were continued.
There is a marked decrease in carotene which occurs even when doses of shark liver oil, too small to cause an increase in the level of vitamin A in milk, are fed.
No toxic-symptoms were noted and the cows remained in good nutritional condition as reflected by the increased production of milk and butterfat.
The present experiments emphasize the lack of correlation between color of the milk and its vitamin A content.

That’s highly disturbing! Thanks YH

Organic dairy, at least here in the USA is fortified with A
http://organicvalley.custhelp.com/app/answers/detail/a_id/186/~/are-vitamins-added-to-organic-valley-milk%3F
From that organic valley page:
Vitamin A: We are required by law to add vitamin A to all of our skim/fat free/nonfat milk, lowfat (1%) milk, and reduced-fat (2%) milk. This is because vitamin A is "fat soluble," so you lose vitamin A content when you reduce fat in fluid milk. We do add vitamin A to some of our whole milk products also. For confirmation, please reference the ingredient label.

I meant the cow fodder, not the actual milk. Since they supplement the feed, the cows produce much more milk, with a much higher level of Vitamin A. Since Vitamin A is colorless, it is very difficult to know how much Vitamin A is actually in the final product. The fortification of low fat and skim makes matters even worse. Organic whole milk that is not grass fed or fortified is probably the safest type of milk.

Kalona Super Natural and Trader's Point Creamery are two Whole Milk Organic Dairy brands I've found in the Midwest U.S. not fortified with A. I'm not currently consuming any dairy but have bought both in the past and trust the quality. I've even been to Trader's Point Creamery because it's close to my home.

@yh Ah, so white butter isn’t “safer.” Thanks for the warning!

You really can’t win. Between the yellow carotene of excesssively grass fed organic dairy, and the inconspicuously retinol loaded conventional dairy, most American dairy doesn’t warrant its own consumption.

I wanted to put this thought somewhere, and maybe someone can tell me a better place.
I was thinking about how baby "foods" such as yolk and milk are loaded with VA, and nature hasn't figured out how to stop that. I assume it is because VA is ubiquitous and part of life on the planet, and it infiltrates our fats, and babies need fat.
My theory is...that where possible (say, when the mother is very healthy and not VA toxic) perhaps the mother ALSO puts in the nutrients the baby needs to detoxify or at the very least to deal with VA.
Perhaps these foods should be studied.

My theory is VA is needed for babies because their immune system is not fully developed(yet).

Vitamin A and Vitamin D levels of milk is interesting. Vitamin A levels are relatively high in milk while D is very low. Almost like Vitamin A is the initial immune system support for offspring and not Vitamin D. Both could be immunomodulating hormones with different roles at different stages of life, with Vitamin D being after infancy. Not sure if any of this is true, may just be rambling. 😉
