该研究旨在评估不同饮食水飞蓟的影响(SM,水飞蓟)粉末水平对生长性能的影响,生产力,豁免权,小肠,血液生化参数,肉质,以及蛋类和胴体的特性。实验对象由108只43天大的鹌鹑组成,分为3个处理(0、0.75和1.50%SM),每个重复4个。对鹌鹑的蛋特性和生长性能进行了评价。对鹌鹑进行安乐死以评估尸体,微生物群,肉的感官特征。分析血液样品的血液学和生化概况。SM在0.75%和1.50%显着(P<0.05)增加采食量,增强的鸡蛋特性(数量,体重,宽度,长度,volume,蛋黄的重量,和蛋壳厚度),空肠和回肠长度,脾脏重量,乳酸菌种群,肉的感官特征,红细胞(RBC),血红蛋白,红细胞指数,白蛋白浓度,球蛋白和促甲状腺激素(TSH)。SM在0.75%和1.50%时降低(P<0.05)car体重量(腹部脂肪,心,脖子,和胰腺),基于产蛋的饲料转化率(FCR),嗜异粒细胞和淋巴细胞的百分比,乳酸脱氢酶浓度,大肠杆菌梭菌群,和大肠杆菌。天冬氨酸转氨酶,丙氨酸氨基转移酶,碱性磷酸酶,0.75%和1.50%SM对肌酸激酶无显著改变(P>0.05)。两个水平(0.75%和1.50%)的SM可能会提高增长,鸡蛋特性,免疫反应,肠道形态和微生物群,肉质和红细胞生成,还能降低鹌鹑的胆固醇。经济可以改善,也是。作者建议在鹌鹑饮食中添加1.0%的SM。
The study aimed to assess the effects of different dietary Silybum marianum (SM, milk thistle) powder levels on growth performance, productivity, immunity, small intestine, haemato-biochemical parameters, meat quality, and egg and carcass characteristics of laying quails. The experimental subjects consisted of one hundred and eight 43-day-old quails divided into 3 treatments (0, 0.75, and 1.50% SM) with 4 replicates each. The egg characteristics and growth performance of the quails were evaluated. Quails were euthanized for evaluation of carcasses, microbiota, and sensory characteristics of meat. Blood samples were analyzed for haematology and biochemical profile. SM at 0.75% and 1.50% significantly (P < 0.05) increased feed intake, enhanced egg characteristics (number, weight, width, length, volume, weight of egg yolk, and eggshell thickness), jejunum and ileum length, spleen weight, lactobacillus population, sensory characteristics of meat, red blood cell (RBC), hemoglobin, erythrocytic indices, concentration of albumin, globulin and thyroid stimulating hormone (TSH). SM at 0.75% and 1.50% decreased (P < 0.05) carcass weight (abdominal fat, heart, neck, and pancreas), feed conversion ratio (FCR) based on eggs produced, percentages of heterophils and lymphocytes, concentration of lactate dehydrogenase, population of coliforms clostridia, and Escherichia coli. Aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, and creatine kinase were not significantly (P > 0.05) altered by 0.75% and 1.50% SM. SM at both levels (0.75% and 1.50%) may improve growth, egg characteristics, immune response, intestinal morphology and microbiota, meat quality and erythropoiesis, and also lead to decreased cholesterol in laying quails. Economics can be improved, too. The authors recommend adding 1.0% of SM to quail diet.
