Effect of DietaryResin on Growth Performance, Blood Biochemistry, and Cecal Microbiota of Growing Rabbits.

Abstract

The present study aimed to examine the impact of dietary supplementation of(BS) (frankincense) resin on growth and carcass traits, blood hematology, serum metabolites and cecal microbiota of growing rabbits. One hundred New Zealand White (NZW) growing male rabbits (6-weeks old) were divided randomly into five groups using different levels of BS (0.00, 0.25, 0.50, 0.75, 1.00 g/kg diet, respectively). When compared to the control diet, daily body weight gain (BWG) and feed conversion ratio (FCR) of rabbits fed BS enriched-diets were improved, while feed intake was significantly decreased. A gradual depression (P < 0.01) in serum triglycerides (TG), total cholesterol (TC) and low density lipoproteins (LDL) were observed with increasing BS level the in diet. Total bacteria count,and salmonella populations were lower (< 0.05) in rabbit groups fed diet enriched with BS than that of the control group. Based on these findings, the dietary supplementation ofenhanced growth, feed efficiency, anti-oxidant status, and minimize cecal pathogenic bacteria in rabbits.
