Summary
This paper, published in the Journal of Dairy Science in 2004, investigates the relationship between forage management systems and the nutritional quality of milk, as expressed through fatty acid composition. The authors likely demonstrate that pasture-based and legume-rich forage systems tend to produce milk with elevated concentrations of CLA and omega-3 fatty acids relative to conserved forage or concentrate-based systems. The findings contribute to the evidence base linking grazing management and forage diversity to improvements in the nutritional profile of dairy products.
UK applicability
Although conducted in the United States, the findings are broadly applicable to UK pasture-based dairy systems, where there is growing policy and consumer interest in the nutritional benefits of grass-fed and mixed-forage dairy production. The results may inform UK farm advisory guidance on forage management as a means of enhancing milk fatty acid quality.
Key measures
Milk fatty acid composition (% of total fatty acids); conjugated linoleic acid (CLA) content; omega-3 to omega-6 ratio; saturated and unsaturated fatty acid proportions
Outcomes reported
The study examined how different forage systems (e.g. grazed pasture, hay, silage, and mixed forage diets) influence the fatty acid profile of cow's milk, with particular attention to beneficial fatty acids such as conjugated linoleic acid (CLA) and omega-3 fatty acids.
