Abstract
This study was performed on three local strains of cocks jGimmizah (G), Golden Montazah (Z) and Silver Montazah (S)j, to investigate the semen characteristics under seasonal variations. In G-strain the overall means of the ejaculated volume, sperm concentration, sperm motility, live sperms, dead and abnormal sperms were 0.338 ml, 2.083X109 sperm/ml, 82.20%, 8585% 7.093% and 7.003% respectively. In 2-strain, the overall means of the previous traits were 0.258 m1,1.86X109 sperm/ml, 82.04%. 82.52%. 10.73% and 6.76%, respectively, while, in 5-strain, the overall means were 0209m1, 2.06X109 sperm/ml, 78.47%. 83.45%, 10.16% and 6.22%. For the overall moons of fructose concentration In semen, the Gistrain came outstandingly first at 2.833 mg/100 ml followed by the Z-strain at 2.744 mg/100 ml and finally the S-strain at 2.687 mg/100 ml. In general the Gimmizah strain was superior for semen characteristics. With respect to the chemical characteristics of seminal plasma: in Gistrain the overall means of the total protein, albumin. cholesterol, lactic dehydrogenase (LDH), sodium, potassium and chloride concentration were 1.092 8/100 ml, 0.561g/100 ml, 29.101 mg/100 ml, 387.45 U/ 100 ml, 292.61 mg/100 ml, 33.347 mg/I00 ml and 242.30 mg/100 ml, respectively. In 2-strain, the overall means of the previous traits were 1.092 9/100 ml, 0.4785 8./100 ml. 29.116 mg/100 ml, 351.75 U/100 ml, 289.11 mg/100 ml. 29.460 mg/100 ml and 243.04 mg/100 ml, respectively, while, in S -strain, the overall means were 1.226 8/100 ml, 0.577 9/100 ml, 27.689 mg/100 ml, 359.57 U/100 ml, 289.11 mg/ 100 ml, 31.258 mg/100 ml and 235.37 mg/100 ml, respectively. Fertility tests were performed during the hatching season from January to May. It was bound that fertility percent age of G-strain was 91.08% followed by Z-strain 89.15% and 5-strain 87.16%. Optimal temperature in relation to fertility percentage was from February to April (20.7-24.659) for G-strain, while, April was best for Z-and 5-strains (24.6C°).
