    Opis:
    Genistein (GEN), an isoflavonoid phytoestrogen, is one of the potent estrogenic compounds derived from plants that can cause disrupting effects on sex organ development in non-mammalian and mammalian species. The present study revealed effect of genistein on germ cell number in the genital ridges during gonadogenesis. Genistein (16 and 24 μg/g egg) was injected into the egg yolk prior to incubation. Effect of genistein on quail-primordial germ cells (PGCs) number was examined by counting the number of Wisteria floribunda (WFA)-positive cells localized in both left and right genital ridges compared with the control group. Both concentrations of genistein resulted in significant decrease of PGC number compared with the control group. Percentages of the sterility rate of the embryo treated with 16 and 24 μg of genistein/g egg were 19% and 23%, respectively. These results provide evidence that genistein may be a germ cell toxicant causing sterility later in life of adult birds. This is the first report on the effect of genistein on PGC number in the genital ridges of the avian embryo.

    Opis:
    The study attempted to analyse and characterize bacteria of the genus Staphylococcus isolated from the surface and contents of quail eggs, taking into account their phenotypic properties, biochemical reactions, antibiotic sensitivity patterns, and PCR to test for the presence of the mecA gene, which is responsible for resistance to methicillin. The study included 45 strains of the genus Staphylococcus isolated from the whites, yolks and shells of table quail eggs. The results obtained indicate that a fairly high percentage of the retail quail eggs tested were contaminated with Staphylococcus bacteria. Among the species isolated (11 in total), the most frequently occurring strains were of Staphylococcus hominis (26.7%), followed by Staphylococcus aureus (15.6%), S.xylosus and S. lentus (13.3% each), while percentages of the other Staphylococcus species were under 10%. The Staphylococcus strains tested had highly differentiated biochemical and enzymatic properties. As many as 7 biotypes were distinguished among the 7 S. aureus isolates, 6 biotypes within the species S. xylosus (6 strains tested), 5 biotypes among the 6 strains of S. lentus, but only 4 biotypes among the 12 S. hominis strains. The antibiotic sensitivity testing showed 15.5% of the strains to be resistant to one or more of the therapeutic agents tested. Moreover, some isolates exhibited intermediate sensitivity to the drugs, particularly to gentamicin (24.4%), neomycin (31.1%), streptomycin (46.7%) and Linco-Spectin (48.9%).

    Opis:
    The aim of this study was to investigate the impact of heat stress on production performance and oxidative stress in different plumage colors of Japanese quail. For this purpose, a total of 100 birds were used in this study. The 25 birds belonged to Wild-type (n=25, grey), Tuxedo (n=25, black), Golden (n=25, yellow) and Recessive white (n=25). The birds were reared for 42 days in an environmentally controlled room at 39°C and relative humidity of 60-65%. The body weight, body weight gain (g/bird/day), and feed conversion ratio were not different between the groups (p>0.05). However, the feed intake (g/bird/day) of the Wild-type had a higher value than the Tuxedo (black) group counterparts between 15 and 21 days different (p<0.05). There was no significant effect of heat stress on the carcass traits (p>0.05). Spleen weights were different between the groups (p<0.05). The yellow group had the highest spleen weight. The highest MDA level was found in the Recessive White variety, followed by Wild-type (grey), Golden (yellow) and Tuxedo (black), respectively. However, there were no statistical differences amongst the groups (p>0.05). There was also no statistical significance in glutathione (GSH) and superoxide dismutase (SOD) levels (p>0.05). The heat shock protein 70 kDa (HSP70) level was significantly different between the groups (p<0.001). The highest percentage was observed in the Golden (5.06%) and the lowest in the White (1.43%) variety. There was no superior color variety of Japanese quail regarding fattening performance and carcass traits. It is conceivable that when considering the stress response of the different colors, the Golden group is more sensitive to stress due to the hepatic and cellular level of HSP70.
