Effect of storage on fatty acid profile of butter from cows fed whole or ground flaxseed with or without monensin

Milk production, milk fatty acid composition, and blood biochemical parameters of Holstein dairy cows fed whole or ground flaxseed instead of extruded soybeans in the first half of lactation

To evaluate the effects of physically processed flaxseed [ground flaxseed (GFS) and whole flaxseed(WFS)] as a replacement for extruded soybeans on feed intake, milk production, milk composition, milk fatty acid (FA) composition and blood biochemical parameters, nine primiparus Holstein dairy lactating cowsaveraging 495 ± 34.5 kg of body weight (BW) and 70 ± 5 days in milk (DIM) were assigned in...

Butter composition and texture from cows with different milk fatty acid compositions fed fish oil or roasted soybeans.

Changing the milk fatty acid composition can improve the nutritional and physical properties of dairy products and their acceptability to consumers. A more healthful milk fatty acid composition can be achieved by altering the cow's diet, for example, by feeding supplemental fish oil (FO) or roasted soybeans (RSB), or by selecting cows with a more unsaturated milk fatty acid composition. We exam...

Characterization of milk from feeding systems based on herbage or corn silage with or without flaxseed and authentication through fatty acid profile

Adapting feeding system is an effective way for improving the nutritional quality of milk as currently intended by dairy industry. The objectives of this work were (1) to characterize milk from feeding systems based on herbage or corn silage with or without flaxseed and (2) to authenticate the milk from the three systems on the basis of the fatty acid (FA) profile. Bulk milk samples were collec...

Effect of diets containing roasted soybean, extruded soybean or their combination on performance and milk fatty acid profile of lactating Holstein cows

The aim of this study was to investigate the effect of diets containing roasted soybean (R), extruded soybean (E) or their combination (RE) on dairy cow performance and milk fatty acid (FA) profile. Nine multiparous lactating Holstein cows (680 ± 25 kg BW; 90 ± 10 DIM; means ± SD) were randomly assigned to a triple 3 × 3 Latin square design. Dry matter intake (DMI), apparent nutrient dige...
