In the current study supplementations of cinnamon () powder (CNP) and turmeric () powder (TP) as an antibiotic growth promoter substitutions on growth performance, intestinal microbiota and hematological profile of broiler chickens have been investigated. A total of 240, one day old as-hatched broiler chickens (ROSS 308) were randomly assigned into five treatments with four replicates per treatment and 10 chickens per replicate. Treatment groups were C: control (fed basal diet); CNP1: 0.5% CNP; CNP2: 1.0% CNP; TP1: 0.5% TP; TP2: 1.0% TP and 500 mg oxytetracycline (OTC)/kg of diet. Body weight gain (BWG), feed intake, and feed conversion ratio (FCR) were improved ( < 0.05) by CNP and TP while OTC improved BWG and FCR. Ileal and cecal and total aerobes were significantly improved while coliforms and were decreased by CNP, TP, and OTC. The percentage of packed cell volume (%PCV), hemoglobin (Hb), red blood cell (RBC) count, and white blood cell (WBC) count was increased by CNP and TP while OTC decreased %PCV, Hb, RBC, and increased WBC count. In conclusion, the results showed that OTC can be safely replaced by CNP and TP at 1.0% dose rate in broiler chicken's diets.
在当前研究中,已对肉桂()粉(CNP)和姜黄()粉(TP)作为抗生素生长促进剂替代品对肉鸡生长性能、肠道微生物群和血液学指标的影响进行了研究。总共240只一日龄刚出壳的肉鸡(ROSS 308)被随机分为五个处理组,每个处理组有四个重复,每个重复有10只鸡。处理组分别为:C:对照组(饲喂基础日粮);CNP1:0.5% CNP;CNP2:1.0% CNP;TP1:0.5% TP;TP2:1.0% TP以及500毫克土霉素(OTC)/千克日粮。CNP和TP提高了体重增加(BWG)、采食量和饲料转化率(FCR)(P < 0.05),而OTC提高了BWG和FCR。CNP、TP和OTC显著改善了回肠和盲肠的和总需氧菌数量,同时降低了大肠菌群和数量。CNP和TP提高了红细胞压积(%PCV)、血红蛋白(Hb)、红细胞(RBC)计数和白细胞(WBC)计数的百分比,而OTC降低了%PCV、Hb、RBC,并增加了WBC计数。总之,结果表明在肉鸡日粮中,1.0%剂量率的CNP和TP可以安全替代OTC。
