“…Pasture quality has a major effect on the performance of grazing animals (Kuczyńska ; Kuczyńska and others ). The quality of the diet of dairy cows in the organic system strongly influences the content and composition of milk protein, fat, and the fat‐soluble micronutrient fraction of dairy products, in particular vitamins A and E (Sakowski and others ). Brodziak and others () reported higher concentrations of Lf and PUFA in milk obtained from cows kept in the traditional system.…”

“…Many factors affect the FA composition of bovine milk, including season (Sakowski and others ), parity (Puppel and others ), access to fresh grazing (Kuczyńska ; Kuczyńska and others ), grazing sward type (Hauswirth and other ), silage type (Dewhurst and others ), polymorphic forms of β‐lactoglobuline (Puppel and others ) or fish oil, and linseed supplementation (Puppel and others , ). Our study showed that the content of monounsaturated fatty acids (MUFA) in milk fat was dependent largely on the concentration of PUFA, and to a lesser extent on the supply of MUFA (Table ).…”

The aim of this study was to determine the nutritional value of organic milk in Poland, investigate the influence of diet on antioxidant capacity and degree of antioxidant protection (DAP), and to examine the effect of season on the bioactive properties of milk from organic farms. From 2014 to 2015, 820 milk samples were collected from 6 organic farms during indoor feeding season (IDS) and pasture feeding season (PS). Pasture feeding season + corn grain (PSCG) cows' daily ration during pasture feeding season was enriched with 4 kg a day of corn to improve dietary energy balance. Milk obtained during PS was found to have a higher fat content, slight but significantly lower protein content compared with milk from IDS. The study showed that the content of monounsaturated fatty acids (MUFA) in milk fat was strongly linked to the concentration of polyunsaturated fatty acids (PUFA) and, to a lesser extent, on the supply of MUFA. The IDS data (concentration of vitamin E, A, and β-carotene) showed the lowest values compared with the PS and PSCG groups. Total antioxidant status (TAS) and DAP showed an increasing trend in organic milk. PSCG was associated with highest level of DAP (9% higher than PS and 79% higher than IDS) and TAS (37% higher than PS and 79% higher than IDS). The results obtained show that supplementation of the basic ration with corn grain improved both TAS and DAP. The higher DAP and TAS value is responsible for product stability, considering the risk factor related to levels of cholesterol-oxide intake in humans.

“…High oxidative stress is common in organs and tissues with high metabolic and energy demands, including skeletal and heart muscle, liver and blood cells . Milk composition can be altered by the feeding regime . Antioxidants can be transferred either directly from the feed to the milk, or indirectly, diet supplements cows' milk .…”

Kouřimská L., Legarová V., Panovská Z., Pánek J. (2014): Quality of cows' milk from organic and conventional farming. Czech J. Food Sci., 32: 398-405.The results of chemical and microbial analyses of raw milk samples coming from organic and conventional farming systems were statistically compared. The samples were analysed during a twelve-month period (June-May). A total of 2206 samples were collected of which 528 were organic. After raw milk was processed, sensory hedonic quality of 171 pairs of organic and conventional non-standardised pasteurised whole milk samples were evaluated using the pair comparison preference test. Four parameters in raw milk, free fatty acids, urea content, somatic cell count and coliform bacteria count, showed no significant differences between the two types of production. Significantly higher contents of protein, casein, lactose, and non-fat solids were detected in conventional milk, which also had a significantly lower freezing point. On the contrary, significantly higher contents of total mesophilic bacteria count and a higher percentage of samples with positive coliform bacteria count were found in organic milk samples. Sensory analysis of pasteurised milk showed no significant hedonic difference between organic and conventional samples.
