选择二元杂交(杜/长)的(28)日龄断奶仔猪90头,平均断奶体重(8.99±1.60)kg,按体重和性别分成3个处理组,每处理3个重复。A组为对照组,饲喂玉米、豆粕基础日粮;B组为添加0.2%(m/m)NS复合乳酸菌制剂到基础日粮中;C组为添加0.2%(m/m)金霉素、0.025%(m/m)阿莫西林和0.012 5%(m/m)的支原净。试验分为3个阶段:试验共30 d,研究微生态制剂NS复合乳酸菌对断奶仔猪生产性能、血液生化指标和减少腹泻率的影响。结果表明,NS复合乳酸菌能显著提高断奶仔猪的生产性能,平均末重、平均增重、平均日增重分别比A组高9.12%,7.64%和7.67%,差异显著(P<0.05);料肉比降低9.70%,差异显著(P<0.05);有效降低断奶仔猪的腹泻率50%,差异极显著(P<0.01);B组的血糖(GLU)含量比A组高20%、超氧化物歧化酶(SOD)活性高10.9%,差异显著(P<0.05),对增强机体抗氧化功能,减少应激作用具有良好效果

Reduced graphene oxide as capturer of dyes and electrons during photocatalysis: surface wrapping and capture promoted efficiency

To elucidate the roles of graphene in photoelectric events and mass transfer during photocatalytic process is important for engineering graphene-semiconductor hybrid photocatalyst. Here, we demonstrated reduced graphene oxide (RGO) capturing dyes and photoinduced electrons during photocatalytic degradation of organic dyes in water. It captures dyes from water through adsorption and desorption irreversible hysteresis, and captures photoinduced electrons from semiconductor through surface junction. The RGO was attached to the surface of TiO(2) in the form of surface wrapping. After one-step photocatalytic reduction of graphene oxide (GO) and TiO(2) in ethanol-water solvent under UV irradiation, the RGO wrapped TiO(2) hybrid (graphene-w-TiO(2)) photocatalyst was obtained. Using visible absorption spectroscopy, we also demonstrated these captured dyes were degraded during photocatalysis. The photocatalytic test showed the RGO significantly improved the photocatalytic activity of this hybrid photocatalyst
