Fatty Acid Profile

Omega 3 Supplement fatty acid profile


C14:0 Myristic 5.3% C18:2 Linoleic 4.8%
C16:0 Palmitic 14.0% C18:3 Linolenic 1.0%
C18:0 Stearic 3.0% C20:5 EPA 11.4%
C18:1 Oleic 11.7% C20:6 DHA 16.8%

Variation in fatty acid profile comes from the raw materials themselves and the need to compensate for ambient temperatures.

Increasing Omega 3 Fatty Acids Can Increase Milk As Well As Fertility (Technical Report 13-05)


UFAC UK have long advocated use of long-chain omega 3 fatty acids to enhance fertility and immune function. Now work from the United States also supports our position that omega 3 fatty acids can also increase milk production with NO detriment to butterfats.

Dr. Jose Santos gave a presentation to the American Dairy Science Association this summer (2013) in Indianapolis. This reported on his work at the University of Florida, where he looked at varying the ratio of omega 3 to omega 6 fatty acids.

Dr. Santos and his team were interested in the impact of altering the ratios of omega 6 to omega 3 fed to mothers in relation to immune function and performance of calves. They also looked at the performance of the mothers; and this is where things get interesting!

Experiment One compared a control with either a saturated fat product (a calcium soap of palm fatty acids) or an unsaturated fat product, high in omega 3 and omega 6 fatty acids.

Figure 2; % Milk Fat as Influenced by Type of Fat Supplement

As would be expected, the extra energy from fat supplementation increased milk yield; but the response was HIGHER for the unsaturated fat supplement than for saturated. Furthermore, use of unsaturated fats has been associated with reduced milk fat; this is clearly not the case here. Both of these effects are statistically significant. Feed efficiency (ie milk produced per kg fed, was also improved, although this was just under the threshold for significance. Feeding unsaturated oils such as those found in UFAC UK products pays dividends.


Experiment Two changed the ratios of omega 6 to omega 3, whilst keeping energy supply the same.

Figure 4; Milk Fat Response to Changing omega 3 to omega 6 Ratios

By increasing omega 3 fatty acids whilst reducing omega 6 fatty acids Dr. Santos significantly INCREASED milk yield and MAINTAINED milk fat levels. Again, this is completely in line with the UFAC UK philosophy that using highly digestible soft oils including fish oil provides cows with MORE energy than is currently predicted from rationing systems. Indeed, Dr. Santos states responses to dietary fats depend on the composition of the FA (fatty acids) in the supplement

Also discussed in the report is work by a co-worker of Dr. Santos, Dr. F.T. Silvestre. When looking at reproductive performance, the kinds of benefits seen in previous studies were confirmed. Cows were fed either palm-based or soft oil-based supplements during transition (30 days pre- and post-calving), followed by palm-based or fish oil-based supplements for 30 days afterwards.

Figure 4; Milk Fat Response to Changing Ω3 : Ω6 Ratios

Again, this work confirms the UFAC UK view that using products with high levels of long chain omega 3 fatty acids improved reproductive performance; and that one facet of this performance is reduction in embryo loss.

Both DYNALAC and GALAXY from UFAC UK comprise soft, highly digestible vegetable oils and significant levels of long chain omega 3 fatty acids from fish oil.


Figure 7: Milk production Response to Increased DHA + EPA

Converting the lactation trial data to actual intake of the long chain omega 3 fatty acids DHA + EPA allows us to produce Figure 7. To put this into context, 500 g of UFAC UK products will supply the following levels of DHA + EPA;

Dynalac 11.1 g

Galaxy 16.4 g

Both of these products have been shown in UK conditions to enhance milk production and improve reproductive outcomes.

UFAC UK continue to use the soft, highly digestible vegetable and marine oils that this study has found to be of significant in improving dairy cow productivity. With our blends of soya, rape, sunflower and olive oils, together with high quality fish oils, we produce products that;


  • Produce milk in a healthy and cost effective manner
  • Supplement forages and enhance dry matter intake
  • Supply essential fatty acids that improve immune function
  • Actively support reproductive performance
