Abstract

The use of herbs and spices has gained increasing interest as feed additives and possible alternative to antibiotics in poultry production. The effects of using different levels of coriander seed powder or extract on selected blood parameters, intestinal microflora, and immune response of broiler chickens were investigated in this study. A total of 420-day-old broiler chicks were randomly assigned to 7 treatments with 4 replicates and fed for 42 days. Results showed that inclusion of 2.0% coriander powder in broiler diets lowered total cholesterol while blood urea was significantly higher in birds on T4 compared to T1 and T2. Furthermore, there were no treatment effects on Lactobacillus bacteria; however, the population of E. coli was significantly higher in the ileum of chickens fed T0. Noticeable significant improvements of antibody titer against Newcastle, infectious bronchitis, and infectious bursal disease were observed in birds receiving coriander extract in water. Immunoglobulin G antibody against sheep red blood cells showed significant improvement in birds fed T3; likewise, immunoglobulin M was significantly higher in birds on T2 and T3 at 28 d of age. These results revealed that coriander extract or powder can be used as antibiotic alternative in broiler feeds.

Highlights

Over the years, antibiotics have been traditionally administered to poultry in order to prevent pathogenic microorganism, thereby increasing some useful microorganism in the intestinal microflora
Guo et al [8] observed in their study that plant extracts led to a decrease in the numbers of harmful bacteria in the caecum while at the same time increasing the numbers of beneficial bacteria
Our results showed that the administration of coriander seed powder had a profound influence on the metabolism of lipids in animals fed on cholesterol containing diets

Summary

Introduction

Antibiotics have been traditionally administered to poultry in order to prevent pathogenic microorganism, thereby increasing some useful microorganism in the intestinal microflora. The presence of these microorganisms in the gut is imperative for effective immunological, physiological, nutritional, and protective health in poultry [1]. Herbs and spices have recently emerged as alternatives to antibiotics in animal production. They are known to exert antimicrobial actions in vitro against important pathogens, including fungi [6]. Guo et al [8] observed in their study that plant extracts led to a decrease in the numbers of harmful bacteria in the caecum while at the same time increasing the numbers of beneficial bacteria
