01 Innovations for products
1. ZHENG CHANG, like most other feed factories in China, used its first-generation layer feed technology with the combination of grinding and mixing to produce common powder layer feed before 2010.
2. From 2011 to 2015, ZHENG CHANG developed the second-generation equipment and technology with hygienic conditioner and mixer to produce high-grade, hygienic and sterile powder layer feed.
3. From 2016 to 2019, the third-generation layer feed coating technology and equipment were developed to produce high-grade, hygienic and sterile particle layer feed.
02 Innovations for technologies
1. Feed produced by the first-generation layer feed technology contained harmful bacteria like Salmonella, E. coli. High segregation, low feed intake, and high feed conversion ratio.
2. Feed produced by the second-generation layer feed technology achieved certain sterilization effect, but high segregation, low feed intake, and high feed conversion ratio still existed.
3. The third-generation layer feed coating technology has realized the transformation from powdered feed to particle feed. Less loss of heat sensitive elements such as vitamins, higher feed intake, and lower feed conversion ratio.
