Fertility and hatching rates in turkey hens fertilized with fresh and frozen semen in the presence of Lake or Tselutin diluent and three sperm concentrations per insemination dose.
| Semen Treatment | Extender | Sperm Concentration (× 106 spz) | Total Fertile Eggs (%) | Hatching Rate (%) |
|---|---|---|---|---|
| Fresh | - | 250 | 90.8 a | 75.6 a |
| Frozen | Tselutin | 600 | 81.9 bc | 51.4 d |

| Extender effect | p = 0.767 | p = 0.974 | ||
| Sperm concentration effect | p = 0.049 | p = 0.004 | ||
