“…Although both of n-3 and n-6 FA are essential and have valuable impacts on human health, excessive levels of n-6 FA and very low levels of n-3 FA (increased n-6 to n-3 ratio) possibly interfering the way of the body to utilize n-3 FA and therefore limit their abundant health benefits (Simopoulos, 2016). LO supplementation could lower the ratio of n-6 to n-3 more than SO supplementation (Antonacci et al, 2018). The ratio of n6 to n-3 is desirable to be closer to 2:1 (Benbrook et al, 2013).…”

There is an awareness in augmenting conjugated linoleic acid (CLA) and n-3 fatty acids (FA), while lowering saturated FA (SFA) in ruminant milk due to their advantageous health benefits for humans. Therefore, we aimed to investigate the effects of soybean and linseed oils on milk yield, milk composition, milk FA profile, and blood lipid metabolites. Eighteen multiparous Egyptian buffaloes fed corn silage and clover hay-based diet were allocated at random for body weight, days in milk, and milk yield into 3 groups of 6 buffaloes each using a randomized block design. Dietary treatments consisted of three concentrate supplements containing no additional plant oil (CON) or containing soybean oil (SO) or linseed oil at a level of 2.6% of dry matter intake (DMI) (400 g/head/d; 25.6 g/kg DMI). Moderate dietary inclusion of SO or LO had no detrimental effects on DMI, milk production, or milk fat per cent. Milk protein, lactose, ash, and total solids concentrations were increased by LO supplementation. The LO diet decreased milk total SFA content (C10:0, C12:0, C14:0, C16:0), augment monounsaturated FA (MUFA), 18:3n-3 FA, CLA, and polyunsaturated FA, as well as lower atherogenicity index and n-6:n-3 compared to CON. On the other hand, the SO diet increased milk fat content of n-6 FA, CLA, MUFA, and n-6:n-3, and decreased the atherogenicity index compared to CON. LO supplementation had no effect on serum concentrations of triglyceride, total lipids, HDL, and LDL. However, the SO group tended to have greater serum total lipids and LDL concentrations and significantly elevated level of serum cholesterol. In conclusion, dietary inclusion of LO in the concentrate supplement of dairy buffaloes could enrich the nutritive value of milk with advantageous FA (n-3 FA, MUFA, and CLA) and lower the atherogenicity index and n6 to n3 ratio without triggering any adverse effects on buffalo performance.

“…"It is therefore expected that a diet with vegetable oils rich in unsaturated fatty acids and secondary fatty components could not only improve the nutritional properties (fatty acid profile) but could also improve the physical properties of milk" [7]. "The most significant changes in milk fat quality relate to rheological (melting) properties, which influence numerous quality aspects of manufactured dairy products.…”

“…Shazly et al [11] observed that "the physical properties of anhydrous milk fat (AMF) such as sold fat content (SFC) of cows and buffaloes supplemented with flaxseed oil (FO), soybean oil (SO), or their mixture (FSO) were affected not only by its content of USFA but also by its contents of lipid-minor components such as cholesterol and vitamin E". Antonacci et al [7] reported that "the soybean-linseed oil blend at 50% resulted in the highest number of favorable nutritional changes in ewe's milk including the decrease in the hypercholesterolemic fraction of milk, the simultaneous increase in vaccenic, rumenic and linolenic acids, the n-6/n-3 ratio lower than 4 and a low atherogenic index". In another study, Lin et al [12] reported "a decrease in the hardness and solid fat index (SFI) of milk fat derived from the cows supplemented with calcium salts of oleic acid and this was also attributed to an increase in monounsaturated fatty acids and a decrease in saturated fatty acids".…”

This study examined the effect of dietary supplementation of DHA-enriched micro algae diet on physical and technological properties of dairy milk fat in terms of the dynamic crystallization and melting behaviour. Two dairy cows were subjected to feeding regime of DHA-enriched micro algae diet and control diet. The experiment was carried out during 21-d to determine the normal (control) and DHA-enriched micro algae diet modified milk fat that were taken for further analysis. The melting and crystallization behaviour of the milk fat from the cows fed control and DHA-enriched micro algae diets was studied using differential scanning calorimetry (DSC), Q1000 (TA Instruments, New Castle, DE, United States). DHA-enriched micro algae supplementation strongly affected the melting and crystallization properties of milk fat. Generally, the onset temperature (°C) of milk fat crystallization was significantly lower in DHA-enriched milk fat as compared to the control. The quantity of heat released by fat crystallization expressed as J/g (peak area) was significantly lower in enriched milk fat. DHA-enriched milk fat also had a lower peak maximum temperature as compared to control in all samples investigated. All melting curves displayed two peaks (lower melting and higher melting peaks) and for melting peaks, DHA-enriched milk fat melted at significantly lower temperature as compared to the control indicating an increase in the degree of unsaturation of milk fat. Melting offset temperature was significantly lower for DHA-enriched milk fat as compared to the control. It can be concluded that from the results of this study, micro algae supplementation significantly altered the milk fat composition and positively affected melting and crystallization behaviour of milk fat.

“…Production of these isomers in the rumen is enhanced as linoleic acid intake increases, indicating the ability of microbes to hydrogenate can be overcome by high levels of unsaturated fatty acids (Loor, Quinlan, Bandara, & Herbein, 2002). Antonacci, Bussetti, Rodriguez, Cano, & Gagliostro (2018) reported that the soybean-linseed oil blend at 50% resulted in the highest number of favorable nutritional changes in ewe's milk taking into account the decrease in the hypercholesterolemic fraction of milk, the simultaneous increase in vaccenic, rumenic and linolenic acids, the n-6/n-3 ratio lower than 4 and a low atherogenic index. Therefore, it can be expected that a diet with vegetable oils rich in unsaturated fatty acids and secondary fatty components could not only improve the nutritional properties (fatty acid profile) but could also improve the physical properties of milk.…”

The experiment was carried out to evaluate the quality of anhydrous milk fat (AMF) of cows and buffaloes supplemented with flaxseed oil (FO), soybean oil (SO), or their mixture (FSO). Lactating crossbred cows and buffaloes were fed with control diet or with one of three supplements: 2% FO, 2% SO, and 2% FSO according to a double 4 x 4 Latin Square Design. The diets with FO, SO, or FSO reduced saturated FA, mainly C4:0, C14:0 and C16:0, while increased the unsaturated FA C18:1 and C18:2 in milk from cows and buffaloes. Cholesterol content decreased in cow's AMF while increased in buffalo's AMF when a diet supplemented with FO, SO, or FSO. The diet with SO or FSO increased the content of vitamin E in AMF obtained from cows (25.06 and 17.89 mg 100 g-1) and buffaloes (28.48 and 30.32 mg 100 g-1) compared with the control diet (11.02 and 15.68 mg 100 g-1), respectively, which correlated positively with scavenging activity for DPPH• (r2 = 0.66) and ABTS• (r2 = 0.67) radicals. Solid fat content (SFC) was high for cow’s AMF, with 58.12-60.37% at 5°C compared to that of buffalo's AMF, with 52.37-56.98%, but was low for cow's AMF at >15°C. Finally, supplementing a diet with vegetable oils, particularly SO, improves the quality of AMF; increases USFA/SFA ratio, vitamin E content, and antioxidant activities
