The objective of this experiment was to evaluate the effect of forage source on the temporal changes in milk conjugated linoleic acid (CLA). Fourteen Holstein cows were divided into two groups. One group (LOT) was fed a corn silage-alfalfa hay mix ad libitum, while the other group (PAS) grazed on alfalfa-grass pasture. Additionally, both groups were fed 8.2 kg d-1 grain supplement containing 650 g of oil composed of fish oil and sunflower oil (1:4). The concentration of cis-9, trans-11 CLA in milk fat of both diets reached maximum levels on day 3 of oil supplementation, declined during day 6, and then remained constant during the reminder of the experiment. Milk vaccenic acid (VA) and trans-10 C18:1 reached their maximum concentrations on days 3 and 6, respectively, of oil supplementation with both diets. In conclusion, the decline in milk cis-9, trans-11 CLA over time was not affected by forage source and may have resulted from an increase in formation of trans-10 C18:1 and C18:0 at the expenses of VA.

The objective of this study was to evaluate the effects of two levels of maize silage and extruded soybeans supplementation on fatty acid profile in milk fat of dairy cows. Eight Holstein cows were distributed in a double 4x4 Latin Square design with a factorial arrangement. The treatment groups were: high maize silage and low lipid, high maize silage and high lipid, low maize silage and low lipid and low maize silage and high lipid. The experimental periods lasted 21 days. Milk samples were collected on days 18 and 19 of each experimental period. The increase of lipid contents in high and low maize silage diets decreased short chain fatty acids concentrations (C4:0 - C12:0). The conjugated linoleic acid content (cis-9 trans-11 C18:2) increased from 3.72 to 4.85, and 4.6 to 5.89mg/g, when extruded soybeans was used in high and low level of corn silage, respectively. The increase in dietary lipids content resulted in higher trans-11 C18:1 fatty acid concentration. Fatty acid trans-10 C18:1 tended to increase with the elevation of the lipids content in the diet. There was significant correlation between trans-10, cis-12 C18:2 and milk fat percentage. The extruded soybeans supplementation decreased shortchain fatty acids and palmitic acid in milk. In addition, this oilseed enhanced the concentration of conjugated linoleic acid (C18:2 cis-9 trans-11) and vaccenic acid, which improved the milk quality for the human health.

Milk Fat Synthesis

Trans- 10, cis- 12 conjugated linoleic acid (CLA), a biohydrogenation intermediate produced in the rumen, is a potent inhibitor of milk fat synthesis. Data from a number of studies where various doses of trans -10, cis -12 CLA have been abomasally infused demonstrate a curvilinear relationship between the percent reduction in milk fat yield and both the dose of trans- 10, cis- 12 CLA infused and the milk fat content of trans- 10, cis- 12 CLA. In addition to a reduction in milk fat output, under some circumstances an increase in milk yield and milk protein output are observed. To date, there has been no examination of the effects of trans- 10, cis- 12 CLA on milk fat synthesis in lactating sheep. The current study was therefore designed to determine if trans- 10, cis- 12 CLA would inhibit milk fat synthesis in lactating sheep. In order to test the effectiveness of trans- 10, cis- 12 CLA in inhibiting milk fat synthesis we used a lipid-encapsulated trans- 10, cis- 12 CLA supplement (LE-CLA) as a means to provide the trans- 10, cis- 12 CLA isomer post-ruminally.
