Effects of induced subacute ruminal acidosis on milk fat content and milk fatty acid profile [PDF]

open access: yes, 2008
Two lactating dairy cows fitted with a rumen cannula received successively diets containing 0%, 20%, 34% and again 0% of wheat on a dry matter basis. After 5, 10 and 11 days, ruminal pH was measured between 8:00 and 16:00 hours, and milk was analysed for

Biophysical modeling indicates a high affinity of ethyl esters of omega-3 polyunsaturated fatty acids to the enzymes of the pro-inflammatory arachidonic acid cascade

open access: yesФармакоэкономика, 2022
Background. Omega-3 polyunsaturated fatty acids (ω-3 PUFAs) are widely used in modern cardiology. The anti-inflammatory effect of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) is realized, in particular, by modulating the activity of the ...
