Abstract

Present study was conducted to investigate the effects of the dietary supplementation of coriander oil on broiler performance, blood characteristics, microbiota, and small intestine morphology measurements. A number of one-day-old broiler chickens (Ross 308) were allocated to five treatments, with four replicates according to a completely randomized design (CRD). Birds were offered either a corn-soybean meal basal diet (control), or the basal diet supplemented with 600 mg/kg of a flavophospholipol antibiotic, 100, 200, or 300 mg/kg coriander essential oil. At 42 days of age, two birds per replicate were selected for blood collection, slaughtered, and its intestinal microbiota and morphology were investigated. The results indicated that weight gain, feed intake, and feed conversion ratio significantly improved by the dietary inclusion of the coriander oil and antibiotic compared with the control treatment (p 0.05). Birds fed the coriander oil and antibiotic diets had lower populations of Escherichia coli than control group in cecum (p<0.05). The dietary treatments influenced the morphology of small intestinal villi. Birds fed antibiotic and coriander essential oil presented higher villus height and crypt depth compared with those in the control treatment (p<0.01). Coriander essential oil supplementation significantly decreased epithelial thickness and the number of goblet cell of the small intestinal compared with the control treatment (p<0.0001). In conclusion, coriander oil was shown to be an efficient growth promoter. The intestinal health improvement obtained with coriander oil was associated with improvements in broiler growth performance.

Highlights

Modern intensive poultry production has achieved phenomenal improvements, resulting in the efficient and economical production of high quality and safe chicken meat and eggs
We investigated the use of coriander oil compared to an antibiotic in broiler nutrition asa natural growth promoting substance on growth performance, some blood parameters, and intestinal microbiology and histological characteristics
Hong et al (2012) showed that broilers supplemented with essential oil had higher high-density lipoprotein (HDL) and lower very low density lipoprotein (VLDL) levels compared with the controls, while no effect was observed on low-density lipoprotein (LDL) concentrations

Summary

Introduction

Modern intensive poultry production has achieved phenomenal improvements, resulting in the efficient and economical production of high quality and safe chicken meat and eggs. The use of feed additives has been an important part of achieving this success. Common feed additives used in poultry diets include antimicrobials and antioxidants (Hashemi et al, 2012). Phytogenics are a relatively new class of feed additives. Evidences suggest that some herbal plants have appetitestimulating properties, anti-bacterial effects, or may have antioxidant functions (Mountzouris et al, 2007). It has been reported that essential oils improved poultry growth performance because of their ability to increase dietary digestibility (Jamroz et al, 2005; Cross et al, 2007), to balance the gut microbial ecosystem, improving gut health (Hong et al, 2012), and to stimulate the secretion of endogenous digestive enzymes (Williams & Losa, 2001; Cross et al, 2007)
