动物科学动物科学
环境科学环境科学
兽医医学兽医医学兽医医学

背景情况:

在牛肉和奶牛养殖中,水质对牛的绩效指标至关重要.
埃及的牛场面临着新兴的流行病,需要对WQ的作用进行调查.

研究的目的:

仔细检查WQ对埃及农场牛PI的影响.
确定影响PI的与卫生有关的风险因素 (HRF) 以及它们与WQ的相关性.

主要方法:

调查了132个农场,使用问卷来识别HRF.
收集和分析132个水样以评估WQ参数 (pH,TDS,硬度,化物,酸盐,硫酸盐,TCC,TCFC).
统计评估以确定WQ参数,HRF和PI之间的相关性,例如料转换率 (FCR) 和奶牛养效率.

主要成果:

显著比例的水样超出了酸盐和微生物计数 (13%-86.3%) 等参数的允许限值.
WQ参数,特别是酸盐和TDS,与肉牛和奶牛养效率的FCR有显著的相关性.
高酸盐水平成为PI最有影响力的预测因素,其次是TDS,硬度,硫酸盐和微生物数量.

结论:

水质对牛的表现有重大影响,酸盐和TDS等特定参数是关键预测因素.
与农场卫生相关的因素与PI的相关性较弱,但显著.
通过适当的水处理和卫生实践优化WQ对于改善畜牧业结果至关重要.

Effects of EDTA on End-Point Detection Methods

Effects of EDTA on End-Point Detection Methods

Different methods, such as visual observance of metal-ion indicators, spectroscopic techniques, and potentiometric methods, can determine the endpoint of an EDTA titration.
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a...
