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.
在禽类生产中，草药和香料作为饲料添加剂以及抗生素的潜在替代品越来越受到关注。本研究调查了使用不同水平的芫荽籽粉或提取物对肉鸡选定血液参数、肠道微生物群和免疫反应的影响。总共420只1日龄肉鸡雏鸡被随机分配到7个处理组，每组4个重复，饲养42天。结果表明，在肉鸡日粮中添加2.0%的芫荽粉可降低总胆固醇，而与T1和T2相比，T4组鸡的血尿素显著更高。此外，各处理对乳酸菌没有影响；然而，饲喂T0日粮的鸡回肠中大肠杆菌数量显著更高。在饮水中添加芫荽提取物的鸡中，观察到对新城疫、传染性支气管炎和传染性法氏囊病的抗体效价有明显显著提高。对绵羊红细胞的免疫球蛋白G抗体在饲喂T3日粮的鸡中显著提高；同样，在28日龄时，T2和T3组鸡的免疫球蛋白M显著更高。这些结果表明，芫荽提取物或粉可作为肉鸡饲料中的抗生素替代品。
