2021年7月在江西新余和余江两个黄鳝养殖试验点开展饲料替代试验,根据不同养殖户养殖习惯和养殖模式(两年段养殖和一年段养殖),分别设置新余0%(全幼杂鱼)组、50%饲料替代组、100%饲料替代组;余江30%饲料替代组、50%饲料替代组、70%饲料替代组.结果显示,50%替代组生长要优于更高比例的饲料替代组(70%或100%),而全鱼组、30%组、50%组之间生长没有明显差异;结合养殖户实践经验,50%饲料替代养殖稳定,技术成熟,可进行广泛示范推广.

以草鱼为研究对象,通过降低草鱼基本日粮里的蛋白质水平,提高脂肪水平,研究日粮对草鱼肌肉营养成分的影响.选取健康度和规格一致的草鱼360尾,随机分成两组:对照组和试验组.每组180尾,分3个水平,每个水平60尾.对照组饲喂基础日粮,试验组饲喂高脂肪水平的日粮,预试验5 d,正式试验56 d.试验结束后对草鱼的肌肉营养成分进行测定.结果显示,验组的草鱼肌肉的水分、粗蛋白、粗灰分和对照组的相比无显著差异(P>0.05);试验组的粗脂肪水平显著高于对照组(P<0.05);以上结果说明在草鱼的基础日粮中降低蛋白质水

Using a single-mode approximation,we carry out the entanglement measures,e.g.,the negativity and von Neumann entropy when a tetrapartite generalized GHZ state is treated in a noninertial frame,but only uniform acceleration is consid-ered for simplicity.In
在鲤鱼饵料分别添加鱼油、豆油、菜籽油配置成等能等氮的饵料,探讨不同脂肪源对其机体抗氧化功能的影响.结果表明,鲤鱼饵料中分别使用鱼油、豆油、菜籽油对鲤鱼血清中的超氧化物歧化酶和过氧化氢酶活性未产生显著的影响(P>0.05).鱼油组总抗氧化能力和谷胱甘肽过氧化物酶活性显著高于菜籽油组(P0.05);鱼油组丙二醛含量显著低于豆油组和菜籽油组(P<0.05),豆油组丙二醛含量显著低于菜籽油组(P<0.05).在鲤鱼饵料中使用鱼油对其机体血清的抗氧化功能效果较好,鱼油优于豆油,豆油优于菜籽油.
We propose three alternative measures for non-Gaussianity of quantum states:sine distance,Bures angle,and Bures distance,which are based on quantum fidelity introduced by Wang[Phys.Lett.A 373 58(2008)].Using them,we evaluate the non-Gaussianity of some re

以吉富罗非鱼为试验对象,在基础饲料中添加1.0%、1.5%、2.0%的酵母水解物,研究不同剂量的酵母水解物对其生长性能的影响.结果表明:在吉富罗非鱼饵料中添加不同水平的酵母水解物对吉富罗非鱼的成活率、肝体指数、脏体指数无显著性影响(P>0.05).试验2组和试验3组吉富罗非鱼的试验末重比对照组显著分别提高了14.19%、9.53%(P<0.05);试验2组和试验3组吉富罗非鱼的增重率比对照组显著分别提高了17.40%、10.88%(P<0.05);试验2组和试验3组吉富罗非鱼的特定生长率比对照组显著分别提
