To make effective prevention and control of reproductive organ disease of breeding geese under the anti-season breeding mode, the characteristics of control principles of infectious diseases of the poultry and the occurrence and prevalence of reproductive organ disease must be combined, so as to carry out scientific prevention and control.At the same time, according to the climate characteristics of summer, the feeding and management of breeding geese and water quality control should also be done well, and many corresponding measures should also be taken, thus obtaining better effect.展开更多
