Reproductive Performance Status of Adult Female Rabbits Administration Spirulina and Combination of Folic acid, B6 and B12

Abstract

The current study aimed to evaluate the effects of oral administration of spirulina (as a food supplement) on the reproductive performance of adult female rabbits. Female rabbits (16 to 18 weeks old) were divided into three groups (10 rabbits/ group). These groups are: (Gr.I) as a control group and (Gr. II) spirulina was given at a dose (0.5 g / kg of body weight) and (Gr. III) was given a complex of folic acid, B6 and B12 (2.5 + 50 +1 mg / kg body weight) all groups were treated for four weeks. At the end of the treatment period, 2 untreated males (two males/ group) were naturally mated with treated females. The results showed that there was no significant difference in the estrogen concentrations among all groups, while the progesterone concentration showed a significant decrease in the third compound group compared to the control group and DXN-spr. Also, the testosterone hormones did not show significant differences in all groups. FSH and LH concentrations appeared to be significantly decreased in the third group than in the other two groups. The fertility rate and the number of female fertilities increased in the second group (DXN-Spr.) compared to the other groups. There was also a significant increase in birth weight and fertility rate in this group compared to the control and group No. 3 groups. We conclude that oral dosed spirulina (0.5 g/kg body weight) acts as a natural antioxidant that improves reproductive efficiency and reproductive hormones.
