Abstract
This study targeted to investigate the effect of Spirulina platensin(SP),vitamin E and their combination on in vivo and in vitro reproductive performance, and some physiological and health indicators of heat stressed rabbit does. Nili-parous NZW rabbit does (n=80) were allocated to four groups.Does in the 1st group (G1) were fed commercial complete feed diet (CFD),
while those in G2, G3 and G4 were fed CFD with SP(300 mg/kg),vitamin E
(100 mg/kg diet)and SP+ vitamin E/kg diet),respectively. All does were naturally mated with fertile NZW bucks (5 bucks per group). Results showed that does in G2 showed significantly(P<0.05) better reproductive performance
(conception rate, kindling rate and litter size), lipid profile (total lipids,cholesterol, triglycerides, high and low density lipoproteins,antioxidant capacity(total antioxidant capacity, glutathione, malondialdehyde, glutathione peroxidase, glutathione S-transferase, superoxide dismutase and catalase),
immunity (lysozyme, IgG and IgM), ovulatory response (CLs number and
ovulation rate), embryo quality, and hatched blastocysts production with higher cell number and inner cell mass as compared to other groups .In conclusion, dietary supplementation with Spirulina platensis (300mg/kg diet), in comparing with vitamin E (100 mg/kg diet) or their combination at the same levels, had positive impact on reproductive performance of rabbit does used in breeding program under heat stress condition in Egypt.
