| Popis: | The objective of this study was to determine the relationship between the number of transferable embryos (TE) and various blood chemistry parameters as a reflection of the metabolic state of cows after superovulatory treatment. Forty-nine Holstein cows were subjected to superovulatory treatment for commercial embryo production. At the time of embryo harvest, individual blood samples were taken from cows for biochemical analysis. All embryos including dead ones as well as non-fertilized oocytes were counted in uterine lavage. Feed samples collected daily for a period of two weeks before embryo harvest, were analyzed for mycotoxins: vomitoxin, zearalenone and T-2 toxin. On average, cows produced 9.45+/-5.60 embryos and oocytes of which 5.27+/-4.20 were TE, 0.37+/-0.80 were dead embryos and 3.82+/-3.78 were non-fertilized oocytes. Higher concentrations of Mg and K were associated with a higher production of TE (p=0.005 and p=0.043, respectively) and higher activity of creatinine kinase was associated with a lower production of TE (p=0.011). |
