Abstract

HRISTOV, H., V. GERZILOV and A. TENEVA, 2004. A study on blood serum protein profiles of pekin, muscovy and mule ducks. Bulg. J. Agric. Sci., 10: 753-756

The study was carried out on the quantitative record of blood serum protein fractions of 20 female Pekin ducks and 15 Muscovy drakes, local population bread on the poultry farm of the Agricultural University, as well as of 25 mule ducks obtained from them by artificial insemination with mixed semen. The total proteins in Peking duck serum were 55 ± 0.39 g/L, in Muscovy drakes - 46.80 ± 0.34 g/L and in mule ducks - 46.1 ± 0.57 g/L. In both parent forms and in the hybrid obtained we reported five protein fractions- prealbumins, albumins, postalbumins, transferins and g-globulins. The relative share of those fractions in Pekin ducks was 0.2 %, 34.65 ± 0.89 %, 14.35 ± 0.93, 16.40 ± 0.68 %, 33.00 ± 1.00 %, respectively; in Muscovy drakes - 6.23 ± 1.25 %, 33.23 ± 0.98 %, 16.92 ± 1.24 %, 12.54 ± 0.86 % and 30.77 ± 1.42 %; in Mule ducks - 1.60 ± 0.53 %, 34.88 ± 0.44 %, 19.40 ± 0.57 %, 11.92 ± 0.56 % and 31.64 ± 0.98 %.
