Item A morphometric study on the skull of the turkeys (meleagris gallopavo)(Bursa Uludağ Üniversitesi, 2018-03-01) Yonkova, Penka; Yılmaz, Bestami; Süzer, Bayram; Serbest, Ayşe; Uludağ Üniversitesi/Veteriner Fakültesi.In this study, 80 turkey skulls (40 females and 40 males) were used. Turkeys slaughtered at the age of 128 days. The females had an average weight of 11.5 kg and the males had 19 kg. We measured 14 features and determined 6 indices on the skulls of turkeys. Our study focused on morphometric differences and comparison of determined features of those skulls for males and female turkeys. Correlations between all features and indices of the skulls were examined for each male and female group, separately. All morphometric measurements were significantly higher in male group. All indices except skull index and foramen magnum index were significantly higher in female group. These measurements showed that males have bigger skulls. Cranial index, facial index, index 1 and index 2 showed that males have narrower and longer skulls while the females have smaller and wider. According to foramen magnum index, foramen magnum of turkeys is slightly vertical oval. Also, ratio of skull length and width is similar for both sexes. This study is the morphometric evaluation of the skull in turkeys. Therefore, this study will lead to further studies on turkeys and other bird speciesItem Ultrasound imaging, biochemical blood analyses, and weight investigations of dissectible fat depots in New Zealand white rabbits(TÜBİTAK, 2012) Yonkova, Penka; Rusenov, Anton; Kanakov, Dean; Zapryanova, Dimitrinka; Vachkova, Ekaterina; Dimitrov, Rosen; Kostov, Dimitar; Serbest, Ayşe; Uludağ Üniversitesi/Veteriner Fakültesi/Anatomi Anabilim Dalı.; 0000-0002-2687-1221; AAH-4081-2021; 54786039100The purpose of the present study was to evaluate changes in real-time ultrasound imaging traits and weight of dissectible fat depots (inguinal, interscapular, and perirenal) in rabbits with different body weights and to monitor the changes in blood glucose and constituents of lipid profiles. In this study, 18 clinically healthy male New Zealand white rabbits were used. The rabbits were fed with standard diet and were divided into 3 groups according to their body weight: group 1 at 1.06 +/- 0.03 kg, group 2 at 2.1 +/- 0.05 kg, and group 3 at 3.06 +/- 0.03 kg. Examined by ultrasonography, the inguinal and interscapular fat depots appeared as bands with weak to moderate echogenicity, whereas perirenal fat was moderate to hyperechoic. The thickness of subcutaneous fat depots measured by ultrasound increased along with body weight and differences between the groups were found to be statistically significant (P < 0.001). The differences in perirenal fat thickness between rabbits from group 1 and group 2 were not found to be statistically significant. Perirenal fat thickness in the rabbits from group 3 was higher (P < 0.001) than that of the other groups. Perirenal fat weight in group 3 correlated positively (r = 0.82; P < 0.05) to body weight. Blood biochemical analysis showed that blood glucose, total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) were in the reference range for all groups regardless of the fact that TG and HDL-C in groups 2 and 3 were significantly higher than those in rabbits from group 1. The in vivo ultrasound screening of adipose tissue, together with blood lipid profile, is an indicator of good health and proper energy balance in rabbits bred for meat or as companion animals.
