On September 25th, Shandong Sinder Technology Co., Ltd. successfully held the 5th China Poultry Grandparent and Large Parent Breeder Enterprise Technical Seminar in Beijing. Over a hundred representatives from grandparent, parent breeder, and large-scale laying hen enterprises across the country attended the conference to discuss key industry issues and enhance breeding practices.
The seminar gathered both domestic and international experts, scholars, and industry opinion leaders to share the latest research findings and practical experiences. Notable speakers included Dr. Glenn Browning, Professor at the University of Melbourne and Director of the Asia-Pacific Animal Health Center, Dr. Zsuzsa Kreizinger from Hungary's HUN-REN Veterinary Research Institute, and Dr. Chris Morrow, Global Technical Director at Bio properties Pty Ltd in Australia. They delivered insightful speeches, sharing their latest research and practical experiences in poultry disease prevention, which resonated strongly with the participants and earned high praise.

Professor Glenn Browning, a distinguished professor at the University of Melbourne, Director of the Asia-Pacific Animal Health Center, and former Chair of the International Organization for Mycoplasmology (IOM), presented his team's latest research results at the seminar. His team has conducted extensive basic research on mycoplasma immune evasion and pathogenic mechanisms. Mycoplasma gallisepticum (MG) and Mycoplasma synoviae (MS) exhibit complex immune evasion mechanisms, leading to lifelong infection in poultry with a high rate of infection once contracted. The study of immune mechanisms plays a crucial role in vaccine development and precise disease prevention. Through the selection of TS11 clones, the University of Melbourne developed a new generation of MG live vaccine, TS304, which causes minimal damage to the respiratory tract of chickens while providing strong immune protection. Professor Browning also shared experiments on the immunosuppressive effects of infectious bursal disease virus (IBDV) and chicken anemia virus (CAV) on mycoplasma immunity, and discussed trials using tylosin in drinking water following TS304 vaccination for subsequent mycoplasma challenges. He emphasized that live mycoplasma vaccination is an important method for reducing mycoplasma infection pressure in poultry farms.

Antibiotic resistance in mycoplasma is one of the key bottlenecks in disease control for laying hens. Dr. Zsuzsa Kreizinger, a senior researcher at Hungary's HUN-REN Veterinary Research Institute, has long been engaged in research on mycoplasma diseases and certain zoonotic diseases. Her team has conducted extensive work on the mechanisms behind mycoplasma antibiotic resistance and pathogen PCR identification. Mycoplasma resistance stems from both natural and acquired resistance, with mechanisms such as biofilm formation, target site modification, and efflux pumps contributing to resistance against antibiotics. Prolonged use of antibiotics easily leads to the development of resistant strains, and resistance genes can be horizontally transferred to other mycoplasma strains, causing widespread resistance.

The prevention of Mycoplasma should start with the purification of breeder flocks. In his report, Professor Chris Morrow, Honorary Associate Professor at the University of Melbourne, Global Technical Director at Bioproperties Pty Ltd, former Chair of the International Organization for Mycoplasmology's Poultry Mycoplasma Committee, and inventor of the MSH live vaccine, emphasized that when breeder flocks and commercial layer farms face infection pressure, early medication for purification combined with immunization using TS11/MSH live vaccines helps poultry develop specific immunity. This approach can reduce reliance on antibiotics during the farming process and gradually purify the farm environment.

At the conference, Professor Zhao Peng from Shandong Agricultural University shared insights on the current prevalence of infectious bursal disease (IBD) and Marek's disease in poultry. For IBD prevention, breeder flocks can be immunized with live vaccines; strong immunization in breeder flocks can reduce vertical transmission and provide early antibody protection for offspring. To prevent Marek's disease, it is necessary to choose live vaccines with moderate virulence and good protective efficacy. However, it is still difficult to completely avoid infections of IBD and Marek's disease on farms. Once infection occurs, auxiliary medicinal treatments can be used. Professor Zhao shared experimental data in collaboration with Xinde Technology, demonstrating the use of Xinbito (信必妥) and lentinan (a polysaccharide derived from shiitake mushrooms) for the prevention and treatment of IBD and Marek's disease. The data showed that when used at the right time, these treatments can reduce damage to immune organs caused by the two diseases, lower morbidity, and improve weight gain in poultry.

Precision disease prevention is based on extensive epidemiological information and scientific innovation. Dr. Yang Tianyao, Poultry Technical Director at Sinder Technology, shared the company's key epidemiological data and customer collaboration cases. Through comprehensive services and precise disease prevention measures, Sinder Technology provides customized disease control solutions for large farming enterprises. The company has established deep cooperative relationships with many large domestic enterprises, working together to improve disease prevention and control standards.
The successful holding of this seminar provided scientific guidance for the development of poultry disease prevention and control in China. The disease prevention efforts in China's poultry farming industry rely on the joint efforts of all practitioners. Xinde Technology is dedicated to precise animal disease prevention and control, providing an information technology exchange platform for upstream and downstream farming enterprises. In the future, Xinde Technology will continue to work together with industry colleagues to promote the sustainable and healthy development of the poultry industry and contribute to the modernization of Chinese agriculture.
