In most of the holdings of bovine animals play an important role in the changes in the ration during dry period. Especially in the peripartal period is limited to the total supply of feed, what negatively affects on antioxidant indexes in blood of dairy cows (Slavik et al. 2008).

According NRC (2001), diets containing under 0.3 mg of Se/kg of dry matter (DM) per day is deficient for antioxidant effect and immunostimulation of organism in dry period.The objectives of this study were to measure the effect of peroral supplementation of selenium (Se) on the changes of plasma concentrations of Se and glutathione peroxidise (GPx) activities in the blood of dairy cows during peripartal period.

From 240 Holstein herd in a two – four lactation-gestation cycle were selected control group (C) and experimental group (D). The blood samples from vena jugularis were collected 21st day before calving (control sampling), on the day of calving, 12th day and 21st day after calving. The same days after control sampling were peroral supplemented dairy cows in D group with 0.3 mg Se/kg/DM in form of Na2SeO3. The control group (C) was without peroral supplementation of Na2SeO3 with the diet containing 0.2 mg of Se/kg/DM. The changes (P>0.005) on the concentration of Se in plasma were determined in D group on the day of calving, 12th day and 21st day after calving as well as the increased activity of GPx (P>0.05) on the 12th day and 21st day after calving in comparison with the control group.

Diskusia

Pekny den prajem, gratulujem k velmi precizne vypracovanej a urcite vyznamnej studii. Pisete, ze Selen a jeho zlozky su v krmnych zmesiach casto deficientne. Z vasej studie je zrejmy jeho jednoznacny pozitivny ucin, k tomu smetuje aj moja otazka: Do akej miery su taketo studie vyuzite ako realny podnet.. apelovanie na zvysene vyuzivanie pridavku Se a jeho zlucenin v krmnych zmesiach?? Dakujem za odpoved a prajem vela uspechov.. a samozrejme sa tesime na monografiu, kde sa viaceri dozvieme viac o vasej studii.

Dobrý den, dakujem Vam za otazku ako aj za prípravu monografie. Táto študia ako aj monografia je zamerana na preventívne podávanie vybraných antioxidantov dojniciam v poslednej fáze gravidity. Vysledkom oboch prác je praktické doporučenie presných dávok Selénu a vitamínu E pre chovatelov dobytka v počas obdobia zasušenia kedy sú gravídne dojnice najviac náchylné na rôzne ochorenia, ktoré sa po pôrode možu prejavit na zníženej produkcii mlieka ako aj zníženom zdraví teliat.
