Abstract

A total number of 244 New-Zealand White (NZW) rabbits (48 sexually mature bucks 9 months of age, and 196 nonparous does 6 months of age) were used in the present study. The study lasted 4 months and was designed to estimate fertilizing ability of bucks and fertility traits of does as affected by injection of Gibberellic and Boric acid or both. Rabbits were divided into four experimental comparable groups (12 bucks and 49 does each). Animals in 1st group were subcutaneously injected with 1 ml saline solution (NaCL) 0.9% and served as a control group, while the rabbits in 2nd, 3rd and 4th groups were injected subcutaneously with 1 mg Gibberellic acid, 2.5 mg Boric acid and mixture of 1 mg Gibberellic and 2.5 mg Boric acids, respectively. The present investigation included two experiments. The first experiment (in vitro) was designed to investigate semen quality and storagability; spermatozoa enzymatic activity and sperm penetration into estrus cow cervical mucus. The second experiment (in vivo) was designed to estimate fertility traitsof does artificially inseminated by bucks treated with the same treatments.  
Results obtained showed that, Diluted semen of bucks injected with Gibberellic and Boric acid or both, recorded higher(P ≤ 0.01)  sperm motility and storagability than control group, during conservation at both incubation and refrigeration temperatures. Dead and abnormal spermatozoa and acrosomal damages percentages of diluted semen recorded significant (P ≤ 0.01) decrease. Spermatozoa enzymatic activityt, decreased significantly (P ≤ 0.01) and sperm penetration into estrus cow cervical mucus significantly (P ≤ 0.01) increased. Physical semen quality decreased significantly (P≤0.05) with progress of conservation time at incubation condition (37 °C)up to 6 hours, or at  refrigeration temperature (4-6 °C) up to 3 days. Fertility traits of NZW rabbit does were significantly (P≤0.0.5 or 0.01) better by injecting Gibberellic and Boric acid or both.
Conclusively, it could be concluded that, injecting rabbits with mixture of Gibberellic and Boric acids improved semen quality and storagability of bucks, and fertility traits of does in comparison with administration of each acid alone.
