Determination of body measurements of Turkish grey cattle with different image processing methods
Abstract
Twenty heads one-year-old Turkish Grey Cattle Breed, which were protected as part of the conservation of native genetic resources at the Sheep Breeding Research Institute, were evaluated as a material. Body measurements for each animal were determined using the classical method (CM) and six different image processing methods: Fixed Scale Photography (FSP), Fixed Object Photography (FOP), Laser Pointer Photography (LPP), Fixed Scale Video (FSV), Fixed Object Video (FOV), and Laser Pointer Video (LPV), and the methods were compared. The correlation coefficients between CM and FSV, FOV, and LPV were calculated as 0.906 (p<0.01), 0.906 (p<0.01), and 0.909 (p<0.01), respectively for withers height (WH). For back height (BH), the correlation coefficients between CM and the same methods were calculated as 0.879 (p<0.01), 0.950 (p<0.01), and 0.944 (p<0.01), respectively. In terms of rump height (RH), the highest measurement difference was observed between CM and FSV with 3.11%, and the lowest difference was observed between CM and FOV with 0.07%. It was determined that Image Processing Methods (IPMs) could be used as an alternative to classical measurement methods for determining WH, BH, RH, and chest deepth (CD) of each type. It was determined that all IPMs could be used as alternative instead of CM for determining the body measurements of Turkish Grey cattle.
