Relationships among dietary roasted whole soybeans (RSB), milk fatty acid profile, and the development of spontaneous oxidized flavor of milk were investigated by using 20 commercial dairy herds. Diets contained 0 to 15.3% of dry matter as RSB. Concentrations of dietary RSB were correlated positively with concentrations of C18:2 and C18:3 in milk fat. Concentrations of alpha-tocopherol, beta-carotene, and ascorbic acid in milk decreased from 0 to 3 d of storage (4 degrees C), and oxidized… 
Feeding dried distillers grains with solubles affects composition but not oxidative stability of milk.
Peroxide values support the findings by the sensory panel that both feeding DDGS at 10 and 25% and vitamin E and C fortification did not practically change the oxidative stability of milk and indicate that feedingDDGS under experimental conditions modified milk composition, but did not contribute to the development of off-flavors in milk.
Ability of 3 tanniferous forage legumes to modify quality of milk and Gruyère-type cheese.
Feeding SF compared with BB and BP increased the content of 18:3n-3 in the milk and the cheese without a negative effect on flavor of the cheese.
Fatty acid composition, vitamin A content and oxidative stability of milk in China
The influence of geographical region and lactation stage on the fatty acid composition, vitamin A content and oxidative stability of milk from Holstein cows and the relationship between milk fat components and milk stability was investigated.
Performance of lactating dairy cows fed whole cottonseed with elevated concentrations of free fatty acids in the oil.
Differences in milk fatty acid concentration and nutrient digestibility suggest minor changes in rumen fermentation; however, feeding WCS with up to 12% FFA did not negatively impact nutrient intake and digestibility or milk yield or composition.
A review of the effects of different feeding regimes of cows on milk fatty acids profile and antioxidant capacity
This bibliography review analyzes the effects of different feeding regimes of cows the nutritional and sanogenic quality of milk, with a particular emphasis on milk content in functional fatty acids
Oxidative stability of milk influenced by fatty acids, antioxidants, and copper derived from feed.
The higher degree of lipid oxidation in milk from cows fed grass-clover silage could not be explained from the concentration of alpha-tocopherol, carotenoids, uric acid, and copper in the milk, but was thought to be highly influenced by the significantly higher concentration of linolenic acid present in milk.


Factors Relating to Development of Spontaneous Oxidized Flavor in Raw Milk
Abstract Factors affecting spontaneous oxidation in 1198 raw milk samples collected from 137 herds were determined. Milk was examined organoleptically for oxidized flavor 48h after collection on a 0
Performance and profiles of milk fatty acids of cows fed full fat, heat-treated soybeans using various processing methods.
Twenty-four multiparous Holstein cows (48 d in lactation) were used in an 8-wk trial employing a completely randomized block design to determine the effect of heat treatment of full fat soybeans on
Conjugated linoleic acid content of milk and cheese from cows fed extruded oilseeds.
The conjugated linoleic acid content of milk and cheese can be increased by the inclusion of full fat extruded soybeans and fullFat extruded cottonseeds in the diets of dairy cows.
Effects of fat source and copper on unsaturation of blood and milk triacylglycerol fatty acids in Holstein and Jersey cows.
Comparison of the plasma triacylglycerol fatty acid profile with the milk fat profile was useful to interpret separate events of biohydrogenation in the rumen and desaturation by the mammary gland.
Influence of dietary fat source on oxidative stability and fatty acid composition of milk from cows receiving a low or high level of dietary vitamin E
Fifteen primiparous Holsteins were used in a latin square design with three periods and three treatments to assess the effect of fat source on milk flavour, yield and composition, and composition of
Further studies on lipid composition of bovine milk in relation to spontaneous oxidised flavour
Milk samples from five commercial dairy herds having severe problems with spontaneous oxidised flavour (SOF) and milk samples from five herds without such problems were analysed for parameters
Effect of supplemental vitamin E and selenium in the diet on vitamin E and selenium levels and control of oxidized flavor in milk from Holstein cows
There was a trend toward reduced oxidized flavor when vitamin E was given, and levels of anti-oxidants in milk and resistance of milk to oxidation were increased.
Effect of α-tocopherol supplementation to dairy cows on milk and plasma α-tocopherol concentrations and on spontaneous oxidized flavor in milk.
An α-tocopherol supplementation study was conducted with 12 Holstein cows, assigned to one of three dietary α-ocopherol levels, 0, 700, and 3000 IU cow−1 d−1, as dl-α-tocopheryl acetate, as well as a field study of four herds with a chronic spontaneous oxidized flavor (SOF) milk problem.
Relation of Natural Copper in Milk to Incidence of Spontaneous Oxidized Flavor
Summary Milk as it is produced by the cow contains a low but variable concentration of copper (natural copper). Results are presented that show a relatively high concentration ( ca. 0.2 p.p.m.) of
Raw soybeans and roasted soybeans of different particle sizes. 2. Fatty acid utilization by lactating cows.
Roasting tended to increase the total tract digestibility of fatty acids, and roasted soybeans tended to increased polyunsaturated fatty acids in milk compared with raw soybeans, primarily because of changes in concentration of C18:2.
