    Carcass discrimination is a very important issue in the evaluation of different sheep breeds as lamb meat for the red meat sector and the study aims to determine the carcass differences of Romanov and Kivircik lambs up to 6 months old by 2D geometric analysis. In this study was carried out with six months old 13 Kivircik and 16 Romanov lamb cold carcasses. Principal components (PC) that describe the most variation in shape were determined for all samples. A discriminant analysis was performed for the mean shapes of two different breeds. In terms of size (centroid size), Romanov's results were higher. The difference in shape (procrustes distance) was statistically significant for the whole carcass. The shape variations were pretty close for the top view of the whole carcass. It was observed that this analysis was not effective in the differentiation of breeds. The most significant analysis between the two feedings was in the side view of the whole carcass. A total of 26 PCs were obtained from the side view of the whole carcass, 25 PCs from the inside view of half carcass, and 12 PCs from the shape analysis made from the top view of the whole carcass as a result of PCA analysis. PC1 was found to describe for more than 40% shape variation for each view. The lower border of Romanov's rib cage was more ventral according to the results. Also, Kivircik had a straighter thoracal and lumbar vertebrae arrangement, while Romanov's was curved. Geometric morphometry can be a useful method for carcass separation.

    This study aims to reveal the statistical difference by measuring the vertebral heart scale and anatomical structures of the heart in different dog breeds. The vertebral heart scale (VHS) has recently been described as a method for measuring the heart silhouettes of dogs and cats. Vertebral heart scale (VHS) may vary in dog and cat breeds due to age, weight, etc. Twenty-one dogs (10 males and 11 females) of different ages and weights were used. Among the dog breeds used are the French Bulldog, Russian Poodle, Rottweiler, Jack Russell, Golden Retriever, King Charles, Pekingese, Belgian Shepherd, Husky, Chihuahua, Cocker, Terrier, Bulldog, Bouvier and Flanders breeds. Multislice detectors were scanned at 80 kV, 200 MA, 639 mGY, and 0.625 mm slice thickness. The resulting images were saved in Digital Imaging and Communications in Medicine (DICOM) format. The obtained sections were measured in 3D-Slicer software. Thoracic height (TH) and cranial vena cava (CVC) measurement parameters were statistically significant with weight (P<0.05). Vertebral heart scale (VHS) was not statistically significant with any parameter in the correlation analysis (P>0.05). At the correlation table of animal weight with the measurements, it was seen that it had a very significant positive correlation with other measurement parameters except vertebral heart score (VHS) (P<0.01). Vertebral heart scale was determined as 9.09 +/- 1.37 vertebrae in females and 9.50 +/- 0.52 vertebrae in males. The study aims to contribute to veterinary anatomy, surgery and internal medicine.
