DNA content of spermatozoa in different genetic lines of turkeys.
The variability of DNA content in turkey spermatozoa of four different lines and its correlation with body weight and sperm concentration were studied. In lines selected for lower body weight the DNA content was 2.034 and 2.036 pg per spermatozoon. In lines selected for higher body weight the DNA content was 2.267 and 2.370 pg per spermatozoon. Sperm concentration in 1 mm3 of semen, however, was higher in lines with a lower body weight (6.08-6.21 million) in comparison with lines selected for higher body weight (5.46-5.67 million). The correlations between the DNA content and sperm concentration were negative (r ranged from -.457 to -.860).
