Table 4.
Fertility and embryo viability after artificial insemination of frozen/thawed chicken semen of Bionda Piemontes (BP), Bianca di Saluzzo (BS) and Pepoi (PP) Italian breeds.
| Breeds | Fresh | Overall | |||
|---|---|---|---|---|---|
| Parameters | BP | BS | PP | Semen | Value |
| Fertility 1 (%) | 4.8 a | 15.55 | 15.89 | 100 a | 16.43 b |
| Fertile eggs/eggs set (n/n) | (11/229) | (31/213) | (34/214) | (38/38) | (114/694) |
| Embryo viability 2 (%) | 36.36 a | 81.25 | 79.41 | 86.84 | 78.26 b |
| Live embryos/fertile eggs (n/n) | (4/11) | (25/31) | (27/34) | (33/38) | (89/114) |
a,b. Different letters within a row indicate a significant difference between the breed and the overall mean value (p < 0.001). 1 Fertility = (fertile eggs/eggs set) × 100. 2 Embryo viability = (live embryos/fertile eggs) × 100.
