AB  - The past three decades revolutionized the goose industry in the world. China 
      holds the world's largest goose breeds stock by 95% of the global total. To 
      optimize the goose industry and cope with ever increasing poultry meat and egg 
      demands, there is a dire need to focus on reproduction, as most geese breeds 
      exhibit poor reproductive performance. The present study was conducted with the 
      aim to add a contribution in the goose industry and research by the histological 
      visualizing step wise development of germ cells during spermatogenesis by 
      microscopy and a histological technique. Yangzhou goose is a synthetic breed 
      developed by using local goose germplasm resources of China. It is popular in the 
      Chinese goose industry due to high productivity and adaptability. This research 
      evaluated the steps of spermiogenesis and stages along with morphological changes 
      in the seminiferous epithelium in Yangzhou goose ganders. For the assessment of 
      various stages of the seminiferous epithelium cycle, testis sections were 
      embedded in molten paraffin wax. The initial steps of spermiogenesis were 
      depicted by changes in acrosomic granules, whereas further stages were identified 
      by nuclear morphological changes. Ten steps of spermiogenesis and nine stages of 
      seminiferous epithelium were identified. Four types of spermatogonia Ad, Ap1, Ap2 
      and B were recognized. The results depicted a clear variation in the diameter of 
      seminiferous tubules (ST), epithelium height (EH), luminal tubular diameter (LD), 
      number of seminiferous tubules per field and the Johnsen score. Microscopy 
      indicated that the stages of seminiferous epithelium were similar to other birds 
      and mammals and the ST diameter, EH, LD and Johnsen score are positively 
      correlated while the number of seminiferous tubules per field is negatively 
      correlated with the ST diameter, EH, LD and Johnsen score. Fertility in Yangzhou 
      ganders can further be improved by visualizing the histological development of 
      germs cells in testis tissues during spermatogenesis after onset of breeding 
      season and maturity. Our results suggest that Yangzhou ganders reach complete 
      sexual maturity at 227 days of age.
