“…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 ).…”

“…Identification with fatty acid standards and quantitative determination of individual fatty acids in crude fat were conducted using an Agilent 7890A gas chromatograph with HP ChemStation software (Agilent Technologies), a flame ionization detector and a Varian Select FAME column (100 m length, 0.25 mm dia, 0.25 μm film thickness; Varian/Agilent Technologies). The analysis involved a programmed run with temperature ramps under the conditions and temperatures described by Puppel and others (). Each peak was identified and quantified using pure methyl ester standards (PUFA no.…”

“…An antioxidant is a chemical substance which, even in low concentrations, significantly delays, or prevents oxidation. Antioxidants can be transferred either directly from the feed to the milk (Nałęcz‐Tarwacka and others ), or indirectly (Whitlock and others ; Allred and others ; Puppel and others , b). The antioxidant properties of milk are due to the presence of several antioxidant enzymes, including catalase, gluthation‐peroxidase, lactoperoxidase, superoxiddismutase, or some vitamins and provitamins like the vitamin A and carotenoids, vitamin E, and vitamin C (Andrei and others ).…”

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.

“…For above reasons, public health guidelines in most developed countries have recommended population-wide reduction in saturated and trans FA and an increase in 18:3n-3, 20:5n-3, and 22:6n-3 in the human food chain to decrease the incidence of chronic disease (WHO, 2003). Although increasing the proportion of polyunsaturated fatty acids (PUFA) in milk is limited due to extensive biohydrogenation of these FA in the rumen, supplementing linseed to dairy cattle increased the proportion of cis -9, trans -11-18:2 ( c 9, t 11 CLA) and n-3 FA, particularly linolenic acid, EPA and DHA in milk (Glasser et al, 2008, Lerch et al, 2012; Puppel et al, 2013). The objective of this study was to characterize milk FA composition responses to different forms of dietary linseed supplements in lactating dairy cows fed a diet based on grass silage.…”

The objective of this study was to determine the effects of linseed oil or whole linseed supplementation on performance and milk fatty acid composition of lactating dairy cows. Thirty six Holstein Friesian crossbred lactating dairy cows were blocked by milking days first and then stratified random balanced for milk yields and body weight into three groups of 12 cows each. The treatments consisted of basal ration (53:47; forage:concentrate ratio, on a dry matter [DM] basis, respectively) supplemented with 300 g/d of palm oil as a positive control diet (PO), or supplemented with 300 g/d of linseed oil (LSO), or supplemented with 688 g/d of top-dressed whole linseed (WLS). All cows were received ad libitum grass silage and individually fed according to the treatments. The experiment lasted for 10 weeks including the first 2 weeks as the adjustment period, followed by 8 weeks of measurement period. The results showed that LSO and WLS supplementation had no effects on total dry matter intake, milk yield, milk composition, and live weight change; however, the animals fed WLS had higher crude protein (CP) intake than those fed PO and LSO (p<0.05). To compare with the control diet, dairy cow’s diets supplemented with LSO and WLS significantly increased milk concentrations of cis-9, trans-11-conjugated linoleic acid (CLA) (p<0.05) and n-3 fatty acids (FA) (p<0.01), particularly, cis-9,12,15-C18:3, C20:5n-3 and C22:6n-3. Supplementing LSO and WLS induced a reduction of medium chain FA, especially, C12:0-C16:0 FA (p<0.05) while increasing the concentration of milk unsaturated fatty acids (UFA) (p<0.05). Milk FA proportions of n-3 FA remarkably increased whereas the ratio of n-6 to n-3 decreased in the cows supplemented with WLS as compared with those fed the control diet and LSO (p<0.01). In conclusion, supplementing dairy cows’ diet based on grass silage with WLS had no effect on milk yield and milk composition; however, trans-9- C18:1, cis-9, trans-11-CLA, n-3 FA and UFA were increased while saturated FA were decreased by WLS supplementation. Therefore, it is recommended that the addition 300 g/d of oil from whole linseed should be used to lactating dairy cows’ diets.
