    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.

    Total oxidant and antioxidant activities in milk with various somatic cell count intervals during discrete cow and buffalo lactation periods
    (Indian Dairy Assoc, 2018) Yigit, A. A.; Cinar, M.; Macun, H. C.; Ozenc, E.; Kabakci, R.; Yazici, E.; Salar, S.
    This study first investigated the total oxidant and antioxidant capacity (TOC and TAC, respectively) in cow and buffalo milk, with various somatic cell count (SCC) levels, having the same lactation numbers(LN). Second, it determined whether there is an association between the TAC and TOC and the lactation number, for the same SCC level. Quarter milk samples, collected from Holstein cows and Anatolian buffaloes, were separated into SCC levels of <= 2x10(5), 2x10(5)-5x10(5), 5x10(5)-1x10(6) and >= 1x10(6) cells mL(-1) for cow milk, and <= 2x10(5), 2x10(5)-4x10(5), 4x10(5)-1x10(6) and >= 1x10(6) cells mL(-1), for buffalo milk. Next, each group was subdivided, according to the lactation number (cows: 1-2nd, 3-4th, 5-6th, buffaloes: 1-4th, 5-8th, 9-12th), and TOC and TAC of the milk were measured. For the same lactation numbers, TOC increased in the cow and buffalo groups with an SCCV >= 1x10(6) cells mL(-1) (p< 0.05). Conversely, TAC decreased in cow milk with an SCC > 5x10(5)cells mL(-1). In buffalo milk, TAC decreased in parallel with the increased SCC. Among the same SCC groups, TOC and TAC were not affected by the lactation number, in cow and buffalo milk. An increased SCC caused an increased TOC and decreased TAC level, for the same lactation number. No relation existed among TOC, TAC and lactation number, for the same SCC level. SCC may be used as an indicator of TOC and TAC in cow and buffalo milk.
