“…Studies comparing the effect of pasture versus TMR feeding systems on the milk fat content have demonstrated that milk produced from TMR systems has a lower or depressed milk fat content [65,66,67,68,69,70]. This observation has been attributed to the high fiber content of a pasture diet in addition to the abundance of materials that induce fat synthesis in the mammary gland, as opposed to TMR diets that differ from fresh pasture systems in their starch content.…”

Milk is a highly nutritious food that contains an array of macro and micro components, scientifically proven to be beneficial to human health. While the composition of milk is influenced by a variety of factors, such as genetics, health, lactation stage etc., the animal’s diet remains a key mechanism by which its nutrition and processing characteristics can be altered. Pasture feeding has been demonstrated to have a positive impact on the nutrient profile of milk, increasing the content of some beneficial nutrients such as Omega-3 polyunsaturated fatty acids, vaccenic acid, and conjugated linoleic acid (CLA), while reducing the levels of Omega-6 fatty acids and palmitic acid. These resultant alterations to the nutritional profile of “Grass-Fed” milk resonate with consumers that desire healthy, “natural”, and sustainable dairy products. This review provides a comprehensive comparison of the impact that pasture and non-pasture feeding systems have on bovine milk composition from a nutritional and functional (processability) perspective, highlighting factors that will be of interest to dairy farmers, processors, and consumers.

“…In this regard, there is a significant difference in the diet of dairy cows in OF vs CF from early spring until early winter. Additionally, milk produced in organic dairy farming has a significantly more concentration of UFA, especially polyunsaturated fatty acid (PUFA) than in conventional farming (KUČEVIĆ & al [3];POPOVIĆ-VRANJEŠ & al [8]). Effects of season, access to fresh grazing, or usage of specific silage types could be used by producers to enhance the content of beneficial FA in milk.…”

“…Primarily due to the successful management of dairy cow's feeding in all stages of production. Managing nutrition, as well as a choice of farming system, can contribute to the control of fatty acids content in milk during the year in all seasons (ELLIS & al [5]; KUČEVIĆ & al [3]; POPOVIĆ-VRANJEŠ & al [8]). Useful information about FA content is one of the best approaches to improving a milk quality.…”

“…Milk produced on an organic dairy farm has a more favorable fatty-acid composition because it contains more unsaturated FA, especially a group of polyunsaturated FA with omega-3 (ELLIS & al [5]; BALTUŠNIKIENE & al [6]; PRANDINI & al [7]). A number of studies show that nutrition of dairy cows, which is based on use of pasture (fresh grazing, or usage of specific silage types), as well as type of farming (organic vs conventional), have the highest effect on fatty-acid content of milk, as it increases the content of polyunsaturated fatty acids, especially omega-3 and conjugated linoleic acid (ELLIS & al [5]; KUČEVIĆ & al [3]; POPOVIĆ-VRANJEŠ & al [8]). The group of unsaturated FA (especially polyunsaturated) has positive effects on human health.…”

In order to determine potential differences among the fatty-acid content in raw cow's milk in terms of organic and conventional dairy farming, various approaches of chemometric tools were applied. Furthermore, reliable regression models for prediction of unsaturated and saturated fatty acids contents in milk based on milk fat content was used. During 12 months research (four seasons) were collected a total of 7.978 samples of raw milk. The results included dendrograms (as results of cluster analysis) and univariate linear models. The cluster analysis covered the annual saturated and unsaturated fatty acid content values. Linear models present the dependence between milk fat and saturated fatty acids content, and milk fat and unsaturated fatty acids content. For all established statistical models, adequate validation procedures were conducted as an important step in testing the performance of the obtained models. Established models can be applied for the purpose of prediction of saturated and unsaturated fatty acid on the basis of milk fat, which was confirmed by internal and external validation parameters (R 2 in some models was higher than 0.90). Also, results of correlation between milk fat and fatty acids content provide very useful information for a breeding organizations and milk producers.
