AB  - Ten Kabbashi rams were used to investigate the relationship 
  between their body weights and testicular measurements. The rams were purchased 
  at 7 months of age and maintained under uniform condition of feeding and management. 
  Body weights and testicular measurements were taken once every month. The testicular 
  measurements (cm) and body weights (kg) were subjected to linear {Y = a+bX} 
  and logarithmic {Y = b<SUB>0</SUB>+b<SUB>1</SUB> ln(X)} regressions where, Y 
  is the testicular measurement and X is the body weight, a and b are constants 
  denoting the intercept and the regression coefficient, respectively. There was 
  a strong and positive correlation between testicular measurements and body weight 
  in Kabbashi rams. The average live body weights increased from 22.95 kg at 7 
  months of age to reach 64.31 kg by 28 months. The average testicular circumference 
  increased from 20 cm at 7 months to 34.5 cm at 20 months of age. Corresponding 
  changes in the testicular length were found to be 12.70 and 20.81 cm at 7 and 
  20 months of age, respectively. The linear regression coefficient for the testicular 
  length and testicular circumference on body weight were 0.214 and 0.287 and 
  the coefficients of determination (R<SUP>2</SUP>) were 0.822 and 0.782. Due 
  to the strong correlation between body weight and testicular measurements, body 
  measurements can be used to select Kabbashi rams for breeding programs. However, 
  further studies are needed to determine the relationship between these subjective 
  morphological criteria and the actual fertility and semen quality in Kabbashi 
  rams.
