Abstract

The aim of the study aimed to find out cheap local bioactive materials that support immunity, antioxidant capacity, and reproductive efficiency of California rabbits. Seventy-two adult rabbit does were equally allocated into six treatments (12, each). All does were fed a basal diet and orally given three ml distilled water as a basal solution during 10 days before mating until 28-days post insemination. Control does (C) received no supplement, G2 (HB) does were given 50mg honeybee/head/day; G3 (DPP) received 50 mg date palm pollen/head/day; G4 (BP) received 200mg bee pollen/head/day; G5 (SY) received three ml of a commercial synbiotic, and G6 (MIX) received a combination of all previous compounds.
Results indicated that all treatments improved (P<0.05) the immunity functions and antioxidant biomarkers. Similarly, all treatments increased (P<0.05) plasma protein, albumin, and globulins, However it reduced (P<0.05) liver enzymes activity. Treatments remarkably reduced the bad cholesterol (free and LDL) and triglycerides, but increased HDL compared with control. Furthermore, all treatments elicited more secretion of ovarian hormones, which in turn increased pituitary gonadotrophins (FSH and LH). Contrariwise, all treatments resulted in lower levels of prolactin.
In conclusion, provision of rabbit does during its productive life with bee products, date palm pollen and synbiotic would be a good solution for improving productive and reproductive performance of such animal.
