Abstract

One hundred and three adult cocks of two different strains (Rhode Island White, 59 semen quality with concomitant effect on and Rhode Island Red, 44) were subjected to  weekly semen collection for four weeks. The Rhode Island White cocks had gross sperm  motility of 80.76± 1.45% while the value for the significant effects of low relative humidity, high Red cocks is 79.43+1.68% but the difference was temperatures, low rainfall and peak amount of insignificant. The Rhode Island White cocks had a higher (P<0.001) sperm concentration (1.93 0.10x10'/ml) than the Red cocks (1.27±0.12x10 /ml) while semen volume  (0.58±0.04ml) and colour (1.96±0.14) for the  Rhode Island White cocks were lower and   (P<0.001) than the corresponding values of  0.80+0.05ml and 2.820.16 for Rhode Island Red cocks. Colour was found to be positively correlated (r= 0.89) with concentration and rate of genetic progress. Breeding soundness total sperm (r=0.61). The correlation between  sperm concentration and volume, and evaluation of the breeding cocks is concentration and total sperm, were 0.72 and of 0.67 respectively.
