Abstract:
Background and Objective: The sex pre-selection for offspring before conception is desirable demand especially for the breeding program of farm animals. This study aimed to evaluate the preconception treatment of monovalent and divalent ions on the primary sex ratio, ovarian structures and serum minerals levels in New Zealand white rabbit does. Materials and Methods: Nine New Zealand white rabbits doe (5.4±0.61 months of age and 2.4±0.35 kg of body weight) were used. Rabbits in the 1st group were given drinking water only (control). While the 2nd and 3rd groups were given 1% of (calcium and magnesium) and (sodium and potassium) in daily drinking water, respectively for 15 days before mating. The embryos of each group were individually collected after three days of mating for primary sex detection using SRY (Sex Determining Region Y) Polymerase Chain Reaction (PCR) assay. Mineral analyses for all studied animals were weekly detected in serum before and after mating. Results: The primary sex ratio for embryos of rabbits does receive (Na+K) produced more males (69.7%) while (Ca+Mg) administrated rabbits does produce more females (72.2%). The mineral treatment leads to a significant increase in the number of corpus luteum, total embryos, follicles bleeding and a significant decline in the count of large follicles. Also, there was no significant change in serum Na and Ca levels in the treated groups compared to the control. Conclusion: The preconception administration of Ca+Mg could produce more females while Na+K could produce more males without adverse side effects on serum minerals concentration.
