Abstract

A total number of 50 males of 13 sires and 22 dams at 36, 40 and 44 weeks of age of of Bronze turkey at Mehallet-Mousa Turkey Station, Animal Production Research Institute at Kafr El-Sheikh Governorate were used in this study. Semen characteristics were recorded at 36, 40 and 44 weeks of age. Results showed that means of semen characteristics were ranged from 78.63 to 88.68 for advanced motility (AM), from 4.06 to 4.16 for Mass motility (MM), from 9.67 to 10.73% for dead spermatozoa (D), from 3.18 to 4.86 for Concentration (Cn), from 6.59 to 6.82 for pH, from 0.32 to 0.41 ml for volume (VOL) and from 89.27 to 90.33% for livability (LIVE) at 36, 40 and  44 weeks of age. Values of coefficients of variation (CV%) ranged from 6.49 to 10.97 % for (AM), from 16.92 to 26.72 % for (MM), from 29.01 to 47.27 % for (dead spermatozoa), from 6.27 to 17.01 %for (Cn), from 1.71 to 6.72% for (pH), from 11.84 to 20.55 % for (VOL) and from 3.10 to 5.27 % for (LIVE) at 36, 40 and  44 weeks of age..Direct additive genetic variance (σ2a) ranged from 10.776 to 18.791 for AM, from 0.176 to 0.392 for (MM), from 2.235 to 5.538 for (D), from 0.013 to 0.083 for (CN), from 0.002 to 0.062 for (pH), 0.002 to 0.003 for (VOL) and from 2.235 to 8.427 for (LIVE). While  maternal additive genetic variance (σ2m)   ranged from 3.088, 3.890 for AM, 0.044 to 0.363 for MM. 0.662 to 2.289 for D, 0.002 to 0.023 for CN, 0.001 to 0.017 for pH, 0.001 to 0.001 for VOL and 0.662 to 0.873 for LIVE. Direct habitability (h2a) had moderate estimates and were ranged from 0.30 for pH at 40 weeks of age to 0.41 for dead spermatozoa and VOL at 36 weeks of age. While maternal habitability (h2m) were low an ranged from 0.07 for pH at 36 weeks of age to 0.14 for VOL at 36 weeks of age. The ranges in predicted breeding values (PBV) for bards ranged from 0.03 to 7.63 for AM, 0.71 to 2.19 for MM traits, 2.84 t  5.33 for dead, 0.22 to 0.58 for Cn, 0.23 to 0.44 for pH, 0.06 to 0.07 for VOL and 2.83 to 5.33 for LIVE traits., for dams ranged from 4.59 to 5.51 for AM, 0.89 to 1.34 for MM traits, 2.14   2.72 for dead, 0.19  to  0.36 for Cn, 0.12 to 4.55 for pH, 0.04 to 0.06 for VOL and 2.14 to 2.70 for LIVE traits for sires ranged from 3.16 to  4.39 for AM, 0.39 to 0.84 for MM traits, 1.37 to 2.24 for dead, 0.11 to 0.19 for Cn, 0.09 to 3.17 for pH, 0.025 to 0.031 for VOL and 1.37 to 2.24 for LIVE traits. The ranges in predicted breeding values (PBV) for males ranged from 5.41 to 9.08 for AM, 0.71 to 2.15 for MM, 2.83 to 5.33 for D, 0.21 to 0.58 for CN, 0.23 to 5.41 for pH, 0.06 to 0.07 for VOL and 2.84 to 5.33 for LIVE. The average positive% of PBV for males were 48.0, 54.0, 54.0, 52.0, 56.7, 48.0 and 66.0% for AM, MM, D, CN, pH, VOL AND LIVE, respectively. .Genetic and phenotypic correlations among the semen characteristics were mostly positive and significantly )P<0.05, P<0.01, P<0.001) and were low to high at 36, 40 and  44 weeks of age.
