Sažetak
Substantial metabolic and oxidative stress and a decrease in immune function have been associated with increased sensitivity to several diseases in dairy cows during the transition period (before and after calving). We investigated the effect of supplementation with linseed (LS), rich in omega-3 polyunsaturated fatty acids (n-3 PUFAs), alone, or in combination with an organic source of selenium, on the plasma metabolic parameters during the transition (10 ± 3 days before to 42 days after calving). A portion of the total mixed ration (TMR) from the control group (C) was replaced with n-3 PUFA-rich LS in both experimental groups (LS and LS + Se), keeping the diets iso-energetic and iso- nitrogenous. In addition, in the LS + Se group, inorganic sodium selenite was replaced by organic selenium. On day 42, we found (a) higher (P < 0.05) LDL level and Sodium ion concentration in the LS group than in the LS + Se and C groups ; (b) lower (P < 0.05) concentrations of triglycerides and lactate in the LS and LS + Se groups than in the C group ; and (c) higher (P < 0.05) urea concentration in the LS + Se group than in the C and LS groups. In conclusion, n-3 PUFA supplementation acted positively on lipid profile and no adverse effect on plasma metabolic parameters were found.
