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 of enhanced growth, feed efficiency, anti-oxidant status, and minimize cecal pathogenic bacteria in rabbits.

摘要

本研究旨在探讨日粮中添加乳香树脂对生长兔的生长性能、胴体性状、血液学指标、血清代谢产物及盲肠微生物群的影响。将100只6周龄的新西兰白兔雄性幼兔随机分为五组,分别饲喂不同水平的乳香树脂(分别为0.00、0.25、0.50、0.75、1.00 g/kg日粮)。与对照日粮相比,饲喂添加乳香树脂日粮的兔子日增重(BWG)和饲料转化率(FCR)有所提高,而采食量显著降低。随着日粮中乳香树脂水平的增加,血清甘油三酯(TG)、总胆固醇(TC)和低密度脂蛋白(LDL)逐渐降低(P<0.01)。饲喂添加乳香树脂日粮的兔组中,总细菌数、大肠杆菌和沙门氏菌数量均低于对照组(P<0.05)。基于这些发现,日粮中添加乳香树脂可促进兔的生长、提高饲料效率、增强抗氧化状态并减少盲肠病原菌数量。
