Captive livestock, especially caged poultry, have frequent micronutrient deficiencies and need to be supplemented in the form of trace element feed additives. Although the trace element feed does not contain energy, it has a close relationship and a huge influence on the metabolism of energy-producing proteins, carbohydrates, fats, etc., and is essential for ensuring the health, growth and development of livestock and poultry. This article will specifically describe the information on trace elements.

China is a big country in the world for laying hens. The commodity hens account for 40% to 45% of the world's stock. In recent years, the annual output of eggs is about 20 million tons. In the collection, grading, packaging, transportation, storage and processing of eggs, eggs are inevitably affected by external forces, resulting in cracking or cracking of the eggshell, resulting in losses of more than 500 million yuan per year, to producers and wholesalers. The economic losses caused are very large. At this time, the influence of trace elements on eggs is crucial. This paper will review the existing mechanisms of the effects of trace elements on eggshell quality.
