This study aimed to evaluate the effects of varying levels of dietary Cynara scolymus (CS) powder on growth performance, carcass characteristics, intestinal microbiota, immune and haemato-biochemical parameters in female quails. A total of 120-day-old female quails used for the research were divided into 3 treatment groups: 0% CS, 0.75% CS and 1.50% CS having 4 replicates (n = 10). Blood samples collected were analyzed for differential leukocyte count, red blood cell count and its indices, uric acid, lipid profile, liver enzymes, calcium, phosphorous, creatinine, thyroid hormone, creatine kinase, lactate dehydrogenase and antibody titres. Quails were euthanized for evaluation of carcass and microbial bacteria and sensory characteristics of the breast and thigh meat. Supplementation of CS at 0.75% and 1.50% increased (P < 0.05) wing, drumstick, ileum, jejunum and spleen lengths, high-density lipoprotein, and decreased (P < 0.05) low-density lipoprotein: high-density lipoprotein ratio. Diets supplemented with 0.75% CS increased (P < 0.05) albumin while 1.50% decreased (P < 0.05) abdominal fat and increased (P < 0.05) corpuscular volume, red blood cell count, lactobacillus population, and color of thigh meat. Both CS levels (0.75% and 1.50%) may improve intestinal morphology, quality of meat, immunity, erythropoiesis, intestinal microbial population, and decrease bad cholesterol in quails.
本研究旨在评估不同水平的羽衣甘蓝（CS）粉对雌性鹌鹑生长性能、胴体特性、肠道微生物群、免疫和血液生化参数的影响。用于研究的 120 日龄雌性鹌鹑被分为 3 个处理组：0%CS、0.75%CS 和 1.50%CS，每组 4 个重复（n=10）。采集的血液样本用于分析白细胞分类计数、红细胞计数及其指数、尿酸、血脂谱、肝酶、钙、磷、肌酐、甲状腺激素、肌酸激酶、乳酸脱氢酶和抗体滴度。处死鹌鹑以评估胴体和微生物细菌以及胸肉和大腿肉的感官特性。在 0.75%和 1.50%水平下补充 CS 增加了（P<0.05）翅膀、鸡腿、回肠、空肠和脾脏长度、高密度脂蛋白，降低了（P<0.05）低密度脂蛋白：高密度脂蛋白比值。补充 0.75%CS 增加了（P<0.05）白蛋白，而 1.50%CS 降低了（P<0.05）腹部脂肪，增加了（P<0.05）红细胞体积、红细胞计数、乳杆菌群和大腿肉的颜色。0.75%和 1.50%CS 水平都可能改善鹌鹑的肠道形态、肉质、免疫力、红细胞生成、肠道微生物群，并降低坏胆固醇。
