    Dietary fig seeds improve growth performance and antioxidant capacity of quail
    (South African Journal Of Animal Sciences, 2023) Tufan, T.; Bolacali, M.; Irak, K.; Arslan, C.; Ozcan, C.; Kaplan, O.; Irmak, M.
    The aim of this study was to determine the effect of the addition of fig seed (FS) as a feed additive in quail rations on growth performance, carcass parameters, and antioxidant status. A total of 2000 one day-old quail chicks were allocated to a control diet (C; n = 400) or diets supplemented with 0.25% (FS0.25; n = 400), 0.50% (FS0.50; n = 400), 0.75% (FS0.75; n = 400), and 1.00% (FS1.00; n = 400) FS. There were five replicates of 80 chicks for each treatment. At the end of the study, the highest body weights and average daily live weight gains were observed in the FS1.00 group, whereas the lowest BW was observed in the control group. There was no statistical difference between the groups in terms of feed consumption, but the feed conversion ratios of all experimental groups were higher than the control group. The addition of FS had a marked effect on slaughter, hot, and cold carcass weights; and leg, chest, and wing weights compared to the control. Addition of FS to the ration increased total protein and albumin levels, whereas it decreased total oxidant status and alkaline phosphatase. Glucose and uric acid values showed a variable trend. As a consequence, it was concluded that the addition of fig seed as a feed additive at 0.50-1.00% of quail rations could be beneficial based on growth performance, carcass characteristics, and blood parameters.

    Investigation of the effects of live weight and sex on oxidative stress and antioxidant parameters in healthy geese - preliminary study
    (Eugen Ulmer Gmbh Co, 2023) Yavuz, E.; Irak, K.; Celik, O. Y.; Bolacali, M.; Ergiden, Y.; Tufan, T.; Gurgoze, S.
    This study was carried out to determine the effects of live weight and sex on oxidant respective antioxidant status in clinically healthy geese. The total antioxidant level (TAS), total oxidant level (TOS), oxidative stress index (OSI), ferric ion reducing agent antioxidant power (FRAP) and Glutathione (GSH) levels were measured in serum samples from a total of 41 geese (18 males and 23 females) at 9 months of age, bred under the conditions of local breeders. While it was determined that live weight and sex had an effect on TOS and FRAP parameters, but it did not affect TAS, OSI and GSH values in geese. A negative relationship between live weight gain and TOS levels was found. It was detected that FRAP levels were higher in female geese than in males (p < 0.05). It was concluded that the relationship between TOS level and live weight of healthy geese should be further investigated and that the FRAP level could be evaluated as an indicator of antioxidant power in healthy geese of different sexes.
