    Determination of the Relationship of Serum Amino Acid Profile with Sex and Body Weight in Healthy Geese by Liquid Chromatography-Tandem Mass Spectrometry
    (Facta-Fundacio Arnco Ciencia Tecnologia Avicolas, 2022) Yavuz, E.; Iiak, K.; Celik, O. Y.; Bolacali, M.; Ergiden, Y.; Gurgoze, S.
    The aim of this study is to determine the serum amino acid profile using Liquid Chromatography-Tandem Mass Spectrometry (LC-MS / MS) in healthy male and female geese of the same age that were raised in similar care and feeding conditions. The animal material of the study consisted of a total of 41 geese, 18 male, and 23 female of the same age (9 months). After a 12h fasting period of the geese, blood samples were taken from V. subcutanaeulnaris into tubes without anticoagulant. After separating the serums, the samples were preserved at -20 degrees C degrees until Methylglutaryl (Met-Glu), Valine (Val), Leucyl-Isoleucine (Leu-Ile), Methionine (Met), Phenylalanine (Phe), Argininosuccinate (ASA), Tyrosine (Tyr), Aspartic acid (Asp), Alanine (Ala), Arginine (Arg), Citrulline (Cit), Glycine (Gly), Ornithine (Orn), Glutamic acid (Glu) were analyzed. The Val, Asp, Arg, Cit, Gly, and Orn levels of male geese were higher compared to female geese in the research (p<0.05). It was determined that Asp, Arg, Cit, and Gly levels increased as the body weights of the geese increased (p<0.05). It was also determined that the effect of Gender x Body Weight interaction on Val, Cit, and Orn levels was significant (p<0.05). As a result; it has been concluded that the serum amino acid profile of healthy geese can vary according to gender and live weight, and more studies are needed to elucidate the reasons for these changes.

    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.
