This study was conducted to evaluate the effects of dietary supplementation of Barodon, an anionic alkali mineral complex, on growth, feed utilization, humoral innate immunity and disease resistance of olive flounder. A basal experimental diet was used as a control and supplemented with 0.1, 0.2, 0.3, 0.4, or 0.5% Barodon. Triplicate groups of fish (26.4 ± 0.2 g) were fed one of the diets to apparent satiation twice daily for 10 wk. The growth performance was enhanced (P < 0.05) linearly and quadratically in fish fed diets containing Barodon compared with that in fish fed the control. Feed utilization was significantly improved by Barodon supplementation. Serum lysozyme and antiprotease activities were increased quadratically in Barodon fed groups. Also, significantly higher superoxide dismutase activity was found in Barodon‐fed fish. Dietary supplementation of 0.1–0.3% Barodon resulted in significant enhancement of fish disease resistance against Streptococcus iniae. The findings in this study indicate that dietary supplementation of Barodon can enhance growth, feed utilization, innate immunity, and disease resistance of olive flounder and that the optimum level seems to be 0.1% in diets.  相似文献   

Differences in Ion Accumulation and Salt Tolerance among Glycine Accessions

Salinity reduces crop yield by limiting water uptake and causing ion‐specific stress. Soybean [Glycine max (L.) Merr.] is sensitive to soil salinity. However, there is variability among soybean genotypes and wild relatives for salt tolerance, suggesting that genetic improvement may be possible. The objective of this study was to identify differences in salt tolerance based on ion accumulation in leaves, stems and roots among accessions of four Glycine species. Four NaCl treatments, 0, 50, 75 and 100 mm , were imposed on G. max, G. soja, G. tomentella and G. argyrea accessions with different levels of salinity tolerance. Tolerant genotypes had less leaf scorch and a greater capacity to prevent Na⁺ and Cl^? transport from soil solution to stems and leaves than sensitive genotypes. Magnitude of leaf injury per unit increase in leaf Na⁺ or Cl^? concentrations was lower in tolerant than in susceptible accessions. Also, plant injury was associated more with Na⁺ rather than with Cl^? concentration in leaves. Salt‐tolerant accessions had greater leaf chlorophyll‐meter readings than sensitive genotypes at all NaCl concentrations. Glycine argyrea and G. tomentella accessions possessed higher salt tolerance than G. soja and G. max genotypes.  相似文献

铁矿粉烧结液相流动性能的特征数方程的建立     

吴铿  申威  杜瑞岭  闫广  门正朝  员晓 《保鲜与加工》2015,(5):26-31

为解决在研究铁矿粉烧结液相流动性能时通常只考虑面积增长率这一终点信息,而没有考虑过程信息的缺陷以及采用多个指标来表征流动性能在使用上的不便,对影响流动性的因素进行了分析,结合量纲分析和白金汉定理推导出了能定量表征流动性强弱的流动性特征数(LD),简化特征数方程后得到等效流动性特征数(Ld Θ)。试验采用了可视卧式高温炉,记录了铁矿粉烧结液相流动的整个过程信息,通过基础实验和对照实验确定液相流动的起点和终点之后,可以得到每一种矿粉相应的等效流动性特征数数值。测量5种铁矿粉在两种方法下的流动性指标,当只考虑面积增长率时的流动性强弱顺序为A>C≈D>B>E,新方法下为Ld ΘA>Ld ΘD>Ld ΘC≈Ld ΘE>Ld ΘB,两种方法下的指标相近,但是综合了各种重要信息的新指标能进一步区分出各个因素对流动性能的影响程度。  相似文献
