- Abstract
Rabbits are a basic source of protein in many areas around the world. Rabbits are characterized by meat of good quality and high protein source. It is of importance to study and predict different rabbit characters. A total of 720 data values of three different breeds of rabbits (NewZeland White, Californian, and Rex) and both sexes were used. Discriminant analysis (DA) was used to classify the three rabbit breeds and sexes based on the morphological characters (body length (BL), chest circumference (CHC), abdominal circumference (ABDC), thigh circumference (THC), ear length (EL) and ear width (EW)). Data were analysed using the procedures of DA on SPSS 23 statistical package. The results were that ear width showed a strong participation (0.65) in discriminating the three breeds and explained most of the variance while body length (- 0.61) was next in importance as a predictor followed by abdominal circumference (0.53) and the other variables were less contribution in the first function. In the second function, ear width showed stronger contribution (-0.64) then chest circumference (0.56) in explaining variations followed by body length (0.50). The other variables were low contributors as predictors in classification of the three breeds. Abdominal circumference is the most significant morphological trait as a discriminating variable (0.70) in discrimination between male and female and explained most of the variance followed by ear width (0.56) then the body length (-0.53). It is found that 59.2 % correct classification of the rabbit breeds using the discriminant functions was achieved and 70.8 % correct classification of the rabbit sexes using the discriminant functions was achieved. From This study, it is concluded that rabbit breeds and sexes can be clearly identified based on morphological traits with low percent of wrong classification by using discriminant analysis which considered a suitable tool for classification purposes.
