It’s now technically possible to increase Omega-3 fatty acids in milk using GM soybean to feed cows.<\/div>\n

Omega-3 oils are extremly good for health (click the Omega-3 tag below for a wealth of evidence).<\/div>\n
\n<\/div>\n
In human trials, GM soybean oil that is rich in SDA Omega-3 oil has been shown to improve blood chemistry measures of cardiovascular health (see here) that are connected to Omega-3. SDA is an effective source of important oils such as EPA and DHA because the body can efficiently convert it to these vital Omega-3 oils. Other oils normally found in plants are less efficiently converted than is SDA.<\/div>\n
\n<\/div>\n
Currently we rely on fish to get the the most beneficial Omega-3 oils like DHA and EPA. GM soybean oils offer a way to protect fish-stocks and health by providing effective alternatives to fish oil.<\/div>\n
\n<\/div>\n
\n<\/div>\n
If they are fed to animals, these new soybeans can also be used to make animal products that healthier in terms of fat profile. A innovative route to provide Omega-3 rich milk is now opening up from feeding experiments (cited in scientific detail below) where cows are given GM soybeans (but for success, the good oils should be be protected from rumen microbes). Similar experiments with poultry would be very interesting.<\/div>\n

Very long chain n-3 fatty acids such as eicosapentaenoic acid (EPA; 20:5n-3) are important in human cardiac health and the prevention of chronic diseases, but food sources are limited. Stearidonic acid (SDA; 18:4n-3) is an n-3 fatty acid that humans are able to convert to EPA. In utilizing SDA-enhanced soybean oil (SBO) derived from genetically modified soybeans, our objectives were to examine the potential to increase the n-3 fatty acid content of milk fat and to determine the efficiency of SDA uptake from the digestive tract and transfer to milk fat. Three multiparous, rumen-fistulated Holstein cows were assigned randomly in a 3 x 3 Latin square design to the following treatments: 1) control (no oil infusion); 2) abomasal infusion of SDA-enhanced SBO (SDA-abo); and 3) ruminal infusion of SDA-enhanced SBO (SDA-rum). The SDA-enhanced SBO contained 27.1% SDA, 10.4% alpha-linolenic acid, and 7.2% gamma-linolenic acid. Oil infusions provided 57 g\/d of SDA with equal amounts of oil infused into either the rumen or abomasum at 6-h intervals over a 7-d infusion period. Cow numbers were limited and no treatment differences were detected for DMI or milk production (22.9+\/-0.5 kg\/d and 32.3+\/-0.9 kg\/d, respectively; least squares means +\/- SE), milk protein percentage and yield (3.24+\/-0.04% and 1.03+\/-0.02 kg\/d), or lactose percentage and yield (4.88+\/-0.05% and 1.55+\/-0.05 kg\/d). Treatment also had no effect on milk fat yield (1.36+\/-0.03 kg\/d), but milk fat percentage was lower for the SDA-rum treatment (4.04+\/-0.04% vs. 4.30+\/-0.04% for control and 4.41+\/-0.05% for SDA-abo). The SDA-abo treatment increased n-3 fatty acids to 3.9% of total milk fatty acids, a value more than 5-fold greater than that for the control. Expressed as a percentage of total milk fatty acids, values (least squares means +\/- SE) for the SDA-abo treatment were 1.55+\/-0.03% for alpha-linolenic acid (18:3n-3), 1.86+\/-0.02 for SDA, 0.23 +\/- <0.01 range=\"36.8\" range=\"45.0\" range=\"1.3\"><\/div>\n
