本研究旨在研究饲粮中添加生物纳米硒(BNSe)对生产性能的影响,血液学,血液化学,抗氧化状态,免疫反应,盲肠微生物群,和鹌鹑的car体特征。总的来说,180只日本鹌鹑(1周龄)随机分为四组,在一个完整的随机设计中,每个9只小鸡重复五次。第一组饲喂不含BNSe的对照饮食,第二,3rd,第4种处理是饲喂补充了BNSe的日粮(0.2、0.4和0.6g/kg饲料,分别)。BNSe在体重(BW)和体重增加(BWG)参数中的最好水平为0.4g/kg日粮。与不添加任何饲料的基础日粮相比,在鹌鹑饲料中添加BNSe可提高饲料转化率(P<0.01)。包含不同的BNSe水平(0.2、0.4、0.6g/kg)对所有car体性状的影响不明显。饮食中添加BNSe(0.4和0.6g/kg)显着增强了天冬氨酸氨基转移酶(AST)活性(P=0.0127),总蛋白和球蛋白(P<0.05),白细胞(WBC)(P=0.031),与对照组相比,红细胞(RBC)(P=0.0414)。膳食BNSe补充显着改善了脂质参数,抗氧化和免疫学指标,血硒水平升高(P<0.05)。BNSe显著增加(P=0.0003)乳酸菌种群数量,降低酵母总数,模具,细菌总数,大肠杆菌,大肠杆菌,沙门氏菌,肠杆菌(P<0.0001)。总之,添加BNSe至0.4和0.6g/kg可以促进生长,乳酸菌种群数量,血液学,免疫学指标,抗氧化能力,和脂质分布,以及下降的肠道病原体在不断增长的鹌鹑。
This study was conducted to examine the influence of dietary supplementation of biological nano-selenium (BNSe) on productive performance, hematology, blood chemistry, antioxidant status, immune response, cecal microbiota, and carcass traits of quails. In total, 180 Japanese quails (1 week old) were randomly allocated into four groups, with five replicates of nine chicks each in a complete randomized design. The 1st group was fed a control diet without BNSe, and the 2nd, 3rd, and 4th treatments were fed diets supplemented with BNSe (0.2, 0.4, and 0.6 g /kg feed, respectively). The best level of BNSe in body weight (BW) and body weight gain (BWG) parameters was 0.4 g/kg diet. Feed conversion was improved (P < 0.01) by adding BNSe in quail feed compared with the basal diet without any supplementation. The inclusion of different BNSe levels (0.2, 0.4, 0.6 g/kg) exhibited an insignificant influence on all carcass traits. The dietary addition of BNSe (0.4 and 0.6 g/kg) significantly augmented aspartate aminotransferase (AST) activity (P = 0.0127), total protein and globulin (P < 0.05), white blood cells (WBCs) (P = 0.031), and red blood cells (RBCs) (P = 0.0414) compared with the control. The dietary BNSe supplementation significantly improved lipid parameters, antioxidant and immunological indices, and increased selenium level in the blood (P < 0.05). BNSe significantly increased (P = 0.0003) lactic acid bacteria population number and lowered the total number of yeasts, molds, total bacterial count, E. coli, Coliform, Salmonella, and Enterobacter (P < 0.0001). In conclusion, adding BNSe up to 0.4 and 0.6 g/kg can boost the growth, lactic acid bacteria population number, hematology, immunological indices, antioxidant capacity, and lipid profile, as well as decline intestinal pathogens in growing quail.
