Abstract Five dietary treatments were applied in a 35-day trial to evaluate the single and combined effects of phytase and citric acid on growth performance, nutrient digestibility, tibia bone mineralization, intestinal morphology, and blood parameters in growing Japanese quails fed diets with reduced content of nonphytate phosphorous (nPP). On day 1, a total of 500 quail chicks were randomly allotted to 5 treatments with 5 cages of 20 birds for each diet: PC (positive control; adequate amounts of nPP), NC (negative control; 0.12 % reduction in dietary nPP content), PHY (NC + 500 FTU phytase /kg), CA (NC + 30 g citric acid /kg), and PHY + CA (NC + phytase + citric acid). After 35 days, the body weight, average daily gain, and apparent total tract digestibility coefficients (ATTDC) of crude protein in quails fed with any of the diets were higher (P

植酸酶和柠檬酸对低磷饲料喂养的肉型鹌鹑的生长性能、营养消化率、骨骼特征、肠道形态和血液成分的单一和联合影响

摘要 在为期 35 天的试验中应用了五种日粮处理，以评估植酸酶和柠檬酸对生长性能、营养物质消化率、胫骨矿化、肠道形态和血液参数的影响非植酸磷 (nPP)。在第 1 天，将总共 500 只鹌鹑雏鸡随机分配到 5 个笼子中，每种饲料有 20 只鸟的 5 个处理：PC（阳性对照；足量的 nPP）、NC（阴性对照；饲料 nPP 含量减少 0.12%） 、PHY (NC + 500 FTU 植酸酶/kg)、CA (NC + 30 g 柠檬酸/kg) 和 PHY + CA (NC + 植酸酶 + 柠檬酸)。35天后，饲喂任何一种日粮的鹌鹑的体重、平均日增重和粗蛋白表观总消化率系数（ATTDC）均较高（P
