Impacts of selenium nanoparticles and spirulina alga to alleviate the deleterious effects of heat stress on reproductive efficiency, oxidative capacity and immunity of doe rabbits.

Effects of dietary inclusion of (SP) and selenium nanoparticles (SeNPs) combination (SP-SeNPs) on the reproductive performance and , reproductive and metabolic hormones, hemato-bichemical parameters, oxidative stress, and immunity of heat-stressed doe rabbis were evaluated. All supplements significantly increased live litter size at birth and weaning, viability rate at birth, hemoglobin and red blood cells, and plasma T3, T4, insulin, total proteins and albumin compared with control. Plasma estradiol 17-β (pre-mating), progesterone (mid-pregnancy), and prolactin (day -7 postpartum) were significantly increased only by SeNPs (0.
