通过投加生物纳米硒饲料添加剂,进行鲤鱼、鲫鱼、白鲢和鳙鱼的含硒量、体重、产量、成活率、饵料系数、抗病力、色泽和肉质的对比试验,说明生物纳米硒的影响作用。结果表明,投加生物纳米硒饵料4个月,鲤鱼、鲫鱼、白鲢和鳙鱼的含硒量明显增加,分别为0.424,0.453,0.285和0.306 mg/kg,分别是对照样的1.64、1.66、1.22和1.28倍。鲤鱼和鲫鱼的体重、产量、成活率分别增加0.085 kg,6298 kg,2.5%和0.015 kg,699kg,3.0%,投药量大大减少,抗病力增强,饵料系数减少,鳞片呈金黄色,具有肉质较紧、肉层厚等优点。
By adding bio-nano selenium feed additives, carp, crucian carp, silver carp and bighead carp selenium content, body weight, yield, survival rate, feed ration, disease resistance, color and quality of the comparative test, indicating bio-nano selenium Impact. The results showed that the selenium content of carp, crucian carp, silver carp and bighead carp increased significantly at 4 months after addition of nanosized bait, which were respectively 0.424, 0.453, 0.285 and 0.306 mg / kg, which were 1.64 and 1.66 , 1.22 and 1.28 times. The body weight, yield and survival rate of carp and crucian carp increased by 0.085 kg, 6298 kg, 2.5% and 0.015 kg, 699 kg and 3.0%, respectively, significantly reducing the dosage, increasing the disease resistance and reducing the feed ration, and the scales were golden yellow with succulent Tighter, meat thick layer of advantages.
