"Feeding the protected canola supplement significantly reduced the proportions of saturated fatty acids C16:0, C14:0, and C12:0 in milk fat; there were corresponding increases in proportions of C18:0, C18:1, C18:2, and C18:3. Yield of C18 monounsaturated and polyunsaturated fatty acids increased by 54%, which is equivalent to 143 g/d."
An old study, but something to keep in mind. Our sacred cow, famous for making everything saturated, a last safe haven. Even the cows fat (at least in the dairy) is being manipulated. I would guess this stuff is in all the dried feed for the cows. Another reason to know your food source yourself.

Human breast milk can be similarly changed. The intake of saturated fats and unsaturated fat can have significant effects on breast milk composition. I believe there is a circulating graph showing the shift in PUFA composition in US breast milk over the last few decades. No surprise, it shows a substantial increase in polyunsaturated fatty acids.
If Mark Twain is any indication, then PUFA has been slowly but surely put on the US population for over 160 years, with much of the institutional efforts coming in the last 50 years or so.

@JulofEnoch I know. But normally the metabolism of the cow saturates the unsaturated fatty acids from grass and alike. This study shows that a special form of canola keeps it unsaturated trough the ruminant metabolism of the cow in to the milk.

Yes, an "aldehyde treated protein" bonded canola oil. Certainly, loading cattle with aldehydes has no negative effects. Biohydrogenation is not a complete process, the encapsulation of oils comes along numerous feeding practices to raise n-3. So much wasted energy with fish meals and algae, I guess why not make nightmare canola.
What I find interesting is that there's no effect on milk yield, when high PUFA typically reduces milk production. I can't access the study, but I'd like to see more.
Coconut oil promotes fat oxidative stability by reducing the portion of PUFA and increasing alpha-tocopherol and causes the least weight-gain in cattle.
