Use of vitamin c to deviate the sex proportion in bitches identified in estrus by colpocitology
Keywords:
Vaginal cytoloty, Ascorbic acid, sex selection, BitchesAbstract
Several studies have been developed trying to clarify the determination of sex and the factors responsible for the deviation of the sex proportion. This study aimed to administer vitamin C in an attempt to promote the deviation of the sex proportion of female dogs detected in estrus by colpocytology. Forty animals, aged between two and seven years, from two kennels in the city of Salvador-BA and metropolitan region were used. The bitches were followed every two weeks using colpocytology to identify the estrus phase. After detecting the onset of proestrus (vaginal bleeding), follow-up was carried out on alternate days in order to assess the best day for covering the animal. The animals were mated for a period of 8 days. The total 40mg/kg of vitamin C was administered orally twice a day. Treatment started 24 hours before mating, ending after the last day of copulation, that is, after 8 days. There was the birth of 58% of females, however this deviation was not statistically significant. We concluded that however further studies should be carried out to try to determine what factors are responsible for the male:female birth rate in dogs.
