Table 3 Semen parameters in samples used for artificial insemination: Volumes, sperm-concentrations and total sperm cells used for AI as well as fertility of the obtained clutches. Only clutches with successful or likely successful artificial insemination are listed. Each row represents one female and each semen data one artificial insemination

  1. Second to fourth column: volumes and concentrations used for AI (1. = first insemination before first egg; 2. = second insemination before first egg. If semen was only examined within the capillary, the concentration is graded like described in the text (sporadic (+), low (++), middle (+++), high (++++) and extremely high (+++++)). Fifth column: 4/3/2 = In a clutch with a total of 4 eggs, 3 eggs were laid after AI (potentially fertilised) and 2 were effectively fertilised.
