In recent years, ALA has attracted much attention as a natural green feed additive. The physical and chemical properties, metabolic process, physiological function of ALA as well as its application and mechanisms in livestock and poultry production are summarized in the paper.展开更多

This paper analyzes various factors during the implementation of sampling work such as preparatory work,sampling tools,sampling process,pretreatment,packaging,transfer,storage conditions and sample delivery. Carrying out the effective quality control can help to ensure the impartiality of the test results so as to provide reliable scientific basis for the department to study regulatory measures.展开更多
