Abstract

The aim of this study is to compare between the Algerian Sloughi dog breed and the Spanish Galgo cross Sloughi raised in the northwest of Algeria and establish mathematical formulas that will allow us to estimate the live weight of dogs based on body measurements in both breeds. Sixteen body measurements, live weight and ten body indexes (cephalic, format, bone, massiveness, head/neck, head/muzzle, tail/body, profile, head length/ears and head width/ears) were used to compare between the studied dogs. 58 Sloughi (34 males and 24 females) and 51 Galgo cross Sloughi (40 males and 11 females) were studied, dogs were adults and unrelated. The effect of breed on body measurements, weight and body indexes was assessed using t-test, the effect of sex on body measurements, weight and body indexes was assessed using the t-test too. Pearson’s correlation was used to identify linear relationship among the different body measurement and body weight, Among the obtained multiple regression models, the highest coefficients of determination (R²) were obtained from the models formed of height at withers, tail length, neck length and head girth in all dogs (R² =0.640), the model formed of height at withers and ears length in Sloughi dog (R²= 0.730) and the model formed of head girth, chest girth and abdominal girth in Galgo cross Sloughi dogs (R²= 0.712). This study concluded that live weight of Algerian Sloughi and Galgo cross Sloughi dogs could be estimated with a high accuracy using some body measurements and statistical methods.
