    Assessment of ejaculate quality in roosters of three laying lines

  • Original language description

    The aim of this study was to examine the semen quality in roosters of three laying lines used in breeding in Czech Republic. The maternal lines Bar Plymouth Rock (BPR -08) and Rhode Island Red (RIR -05), and the maternal line Light Sussex (SU -07) were used. Ejaculates were collected four times during laying period of hens by dorso-abdominal massage. The following parameters were determined: volume, concentration of spermatozoa, motility and total sperm abnormality. Statistically significant differenceswere found in volume of ejaculate between all three lines (from 0.55 to 0.80cm3). The highest volume as well as the highest concentration of spermatozoa (2.39 x 106/mm3) were found in BPR. Statistically significant differences were found also in motility of spermatozoa between BPR and RIR (68.59 vs. 77.19%). However, very high percentage of sperm abnormality were found in all three lines (from 56.29 to 72.63%). This phenomenon may be caused by transportation of ejaculate into laboratory
