    Age-and sex-related changes in selected hematological parameters, lipid peroxidation and erythrocytes osmotic fragility of Turkish Angora cats
    (Hellenic Veterinary Medical Soc, 2022) Kabakci, R.; Yigit, A. A.; Kara, E.; Cinar, M.; Ekici, H.; Aluc, Y.
    This study was conducted to investigate the changes in selected hematological parameters, lipid peroxidation and osmotic fragility of erythrocytes in Angora cats depending on age and gender. For this purpose, the blood samples were collected from vena saphena medialis of 9 young and 14 adult cats which were also classified as male (n=12) and female (n=11). Following hematological analysis, samples were washed with PBS by centrifugation and 10% hematocrit suspension was prepared from the erythrocytes pellet for the osmotic fragility test. The concentration of malondialdehyde (MDA) was also measured from lysed erythrocytes to determine lipid peroxidation level. Red blood cells (RBCs), hemoglobin, and hematocrit were significantly (P<0.001) high in adults while the mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC) were significantly (P<0.05) high in young cats. Erythrocyte MDA level was also higher statistically (P<0.05) in adult cats than in young cats. There was no significance (P>0.05) in these parameters between male and female cats. Findings of fragility tests showed that erythrocytes of young and male cats were statistically more susceptible to hypotonic NaCl solutions than those of adult and female cats, respectively (P<0.01, P<0.05). It was concluded that erythrocytes related parameters in Angora cats changed depending on age rather than gender except for stability of RBCs.

    Determining the effects of black cumin seed oil on performance and meat fatty acid profile of broiler chickens
    (South African Journal Of Animal Sciences, 2019) Demirci, M.; Karsli, M. A.; Aluc, Y.
    This study was designed to investigate the effects of adding black cumin (Nigella sativa L.) seed (BCS) oil to diets for broiler chickens on their performance and the meat fatty acid profile of the meat. Broiler chicks were assigned to three groups. The unsupplemented control did not receive BCS oil. The two treated groups received 0.5% and 1% BCS oil. The live weight and live weight gain of the experimental groups were generally greater for the treated groups than for the control group. Feed consumption did not differ among groups, and thus the group that was fed the diet supplemented with 1% BCS oil was most efficient. Total saturated fatty acids were lower, and polyunsaturated fatty acids were greater in the treated groups, but monounsaturated fatty acids were greater in meat from the control group. As a result, it can be concluded that the addition of 0.5-1% BCS oil into the diets of broiler may improve the performance of chicks and enrich the meat quality by creating meaningful changes in meat fatty acid profiles, especially in terms of total polyunsaturated fatty acids.
