14 internship
作者:分类:默认分类标签:

  As I said on Monday I would go to visit another food factory to finish my internship. Today my sponsor took me to the factory today, and I visited the different workshops. I was able to take pictures and ask questions about the part of the information I confused.
  This food factory named ZhengDa, it is originally from Thailand, and this factory only produces chicken, and it is the biggest chicken factory in China. On Thursday, I visited the breeding hens workshop, division workshop and processing workshop.
  The factory's directors answered me my question how could the breeding hens growth periods are only 42 days.

  The short growth period is not caused by hormone. When the factory selects the breeding hens, the factory would only select the big hens' eggs. For example, Yao Ming's kids must be bigger than our's kids, therefore those eggs would have good gen to help those breeding hens' growth periods shorter.
