2006
R. K. Mossa
A total of 24 adult male aged 32 weeks from Iraqi local drakes were used in this study to determined some semen characterization, drakes devided randomly into three equal groups and subjected to three semen collection frequencies (once daily, twice daily and once every 2 days) for- 18 consecutive days. The study revealed the following results: 1- Semen characteristics of Iraqi local drakes were, semen volume 0.65ml, spermatozoa concentration 3.52 X 10 9, sperm motility and Abnormality 81.64, 13.14% respectively, pll value 7.1 and individual motility 84.2%. The concentration of glucose, protein and cholesterol in semen plasma were 95.8ml/100ml, 1.22mg/ 100 ml and 102.4 Mnol/ml respectively. 2— The total mean semen volume over 18 days period and total number of spermatozoa produced by the drakes increased significantly as the collection frequency in creased from once over 2 days to twice daily from 3.42 to 8.90ml and 5.85 x 109 to 10.72 x 109 respectively. 3- The average semen volume per collection and the average number of spermatozoa per ejaculate decreased significantly as the collection frequency increased from once over 2days to twice daily from 0.91 to 0.67ml and 1.96 X 109 to 0.92 X 10 9 respectively. 1- , 4- No significantly difference showed on concentration of spermatozoa with the . frequency of collection over 3 periods. 5- Analysis of semen from birds were ejaculated twice daily was showed that the second collection inferior to the first in total number of spermatozoa, total volume of semen and concentration of spermatozoa.
