Abstract
In this study, the use of the three-dimensional modeling method was tested in taking some body measurements in camels with a practical method and was compared with other measurement methods. As the animal material of the study, 12 single-humped dromedary female camels and 14 double-humped Camelus dromedarius × Camelus bactrianus: F1 male camels, a total of 26 camels, were used in three camel farms in Incirliova district of Aydın province. The body measurements are taken from each animal by using different three methods, namely by the manual method (MM), by the photography method (PM), and by the three-dimensional modeling method (3D) were the withers height (WH), the back height (BH), the rump height (RH), the body length (BL), the brisket height (BRH), the abdominal height (AH), the shoulder width (SW), and the rump width (RW), and these values were compared with each other. As a result of this study, the mean values of MM and 3D measurement values were very close to each other and the difference between them was found to be statistically insignificant (P < 0.05). The difference between the means of PM and MM/3D measurement values was found to be significant (P < 0.05). In the measurements taken by MM, 3D, and PM methods in male camels, the values obtained by MM and 3D methods for WH, BH, RH, BRH, AH, BL, and SW were very close to each other and the differences between them were found insignificant statistically (p < 0.05). On the determined regression graph, a linear was found between MM and 3D measurement values. As a result of this study, it has been determined that the 3D modeling method can be used as a remote and more practical method in determining the morphological features of large-scale animals such as camels more reliably, more easily, and more practically.
Highlights
It is important to determine or to measure the morphological characteristics in defining species and the races within those species
Measurement values of Rump Height (RH), Body Length (BL), Shoulder Width (SW) and Rump Width (RW) were very close to each other in Manuel Method (MM) and 3- using a threedimensional (3D) methods, and the differences were statistically insignificant (p < 0.05), but the difference between the measurement values determined by MM and Photography Method (PM) (p < 0.05) was found significant (Table 1)
The values measured by 3D and PM methods for Brisket Height (BRH) and Abdominal Height (AH) were close to each other and the difference was found to be statistically insignificant (p < 0.05), but the difference between MM measurement values of the same regions and the values obtained by other methods was statistically significant (p < 0.05)
Summary
It is important to determine or to measure the morphological characteristics in defining species and the races within those species. Estimation of some physiological characteristics is difficult and time consuming for researchers and breeders in animal breeding studies. All these difficulties have created problems in the work of researchers.Studies have attempted to estimate the characteristics of populations or the identification of races from these criteria by taking measurements on a small number of animals. The use of body measurements technically and scientifically in the evaluation and breeding of farm animals at the end of the last century has further increased the importance of the subject (Zehender et al 1996). Studies have been carried out for many years to develop practical and applicable methods to define morphological features and especially body measurements and to determine some physiological features in many animals (Wu et al 2003; Tasdemir et al 2011; Ozkaya, 2012)
