Drenching free system in waterfowl incubator

　　Starting to drench the goose eggs at the 14th day is for dissemination of embryo and eggshells brittle, complementary measures aimed at helping embryonic shells pecked. Without this system, it takes a lot of human resources and work hours to do the work. Use drenching free system in waterfowl incubator, adjust the micro-environment of incubator, did not affect hatching performance. Hatching rate of fertilized eggs could be enhanced 1% by the improvement and upgrading of equipment and technique. According to calculation, hatching operators hatches 100,000 goose eggs monthly, and the fertility rate is 80% and the hatching rate of fertilized eggs is also80%. If the gosling was 70 NTD for each, the production could increase income about 38,400 NTD for a month, and it could increase 460,800 NTD for a year; this result could be the reference for the industry.
