脂肪酸钙对肉鸡生产性能、肉品质及血浆生化指标的影响
摘 要
动物的生长与发育需要摄入油脂来提供能量和必需的脂肪酸。不同脂肪酸来源和配比会影响油脂的吸收利用。脂肪酸钙作为一种新型的饲料添加剂广泛应用于畜禽养殖业中，能够在一定程度上替代畜禽饲料中的油脂和谷物成分。为了探究脂肪酸钙对肉鸡生产性能、肉品质及血浆生化指标的影响，本实验采用324羽1日龄快大型黄羽肉鸡（青脚麻鸡），根据体重相近原则随机分为对照组（大豆油组）、大豆油+脂肪酸钙组及脂肪酸钙组3个组，分为3个饲养阶段，分别为120日龄、2140日龄、4152日龄，三个阶段油脂添加量分别为1.8%、3.2%和4.2%。试验结果表明，与对照组相比，脂肪酸钙完全替代大豆油可显著降 *51今日免费论文网|www.51jrft.com +Q: ^351916072^ 
低黄羽肉鸡生产性能（P<0.05），152日龄黄羽肉鸡的体重，日增重，料重比均有明显下降（P<0.05），且显著增加了肉鸡料重比（P<0.05）；与对照组相比，添加脂肪酸钙不影响胸肌肉品质（P>0.05）；与对照组相比，添加脂肪酸钙对TP、ALB、ALP、GLU、TG、CHDL、GLOB等血浆生化指标无显著影响（P>0.05）。与对照组相比，脂肪酸钙完全代替肝脏SOD、GSHPX显著升高（P<0.05），但血浆TAOC、SOD、CAT及GSHPX显著下降（P<0.05）；脂肪酸钙部分代替肝脏GSHPX显著升高（P<0.05），但血浆TAOC、SOD、CAT及GSHPX显著下降（P<0.05）；
EFFECTS OF FATTY ACID CALCIUM ON PERFORMANCE, MEA QUALITY AND PLASMA BIOCHEMICAL INDEXES OF BROILERS
ABSTRACT
Animal growth and development requires the intake of fat to provide energy and essential fatty acids. Different fatty acid sources and ratios will affect the absorption and utilization of oil. Fatty acid calcium as a new type of feed additive is widely used in livestock and poultry breeding industry, and can replace fats and grains in livestock and poultry feed to some extent.In order to investigate the effect of fatty acid calcium on broiler performance, meat quality and plasma biochemical indicators, this experiment used 324 1dayold fast largescale yellowfeather broilers (greenfooted chicken), randomly divided into control groups (soybean oil Group), soybean oil + fatty acid calcium group and fatty acid calcium group 3 groups, The test period is 52 days, divided into three feeding stages, respectively 120 days old, 2140 days old, 4152 days old, in which the amount of oil added in the first stage is 1.8%; the amount of oil added in the second stage It is 3.2%; the amount of fat added in the third stage is 4.2%.The test results show that compared with the control group, the complete replacement of soybean oil with fatty acid calcium can significantly reduce the production performance of yellow feather broilers (P<0.05). The body weight, daily weight gain, and feedtoweight ratio of 152dayold yellow feather broilers Significantly decreased (P<0.05), and significantly increased the broiler feed weight ratio (P<0.05); compared with the control group, fatty acid calcium added in animal food has no concern with meat quality(P>0.05); compared with the control group, fatty acid calcium added in animal food has no concern with biochemical indicators(P>0.05); compared with the control group, fatty acid calcium completely replaced liver SOD, GSHPX significantly increased (P<0.05), but plasma TAOC , SOD, CAT and GSHPX decreased significantly (P<0.05); fatty acid calcium replaced liver GSHPX significantly increased (P<0.05), but plasma TAOC, SOD, CAT and GSHPX decreased significantly (P <0.05);
