In modern, large-scale layer farming operations, maintaining peak egg production and ensuring the stability of egg quality are the core metrics by which a farm's profitability is measured. However, many farmers are frequently plagued by two major challenges: "diarrhea in laying hens" and the occurrence of "fecal-soiled eggs." These issues not only lead to a decline in eggshell quality but also result in significant feed wastage, and can even trigger widespread respiratory or immune system diseases.

African foot-and-mouth disease (FMD) in cattle and sheep is an acute, highly contagious infectious disease caused by the foot-and-mouth disease virus. Classified under the genus *Aphthovirus* within the family *Picornaviridae*, it is designated by the World Organisation for Animal Health (WOAH) as a notifiable animal disease and is also classified as a Class I animal disease in my country; it is widely prevalent across the African region and poses profound threats. This disease primarily affects cloven-hoofed animals, such as cattle and sheep; characterized by its rapid spread and high pathogenicity, it inflicts devastating blows upon the livestock industry.

In large-scale poultry farming operations, "soft leg disease" is a prevalent and common complex syndrome. Rather than being a single, distinct ailment, it is a collective term for a series of symptoms triggered by a multitude of factors. This condition poses a severe threat to chicks, growing birds, and laying hens alike, directly impacting farming profitability. As a company dedicated to the R&D and manufacturing of feed additives and veterinary pharmaceuticals, AGOVEE is deeply committed to the field of healthy poultry farming. We have conducted a comprehensive analysis of the causes, detrimental effects, and clinical symptoms associated with soft leg disease in poultry. Consequently, we have developed specialized products for its prevention, control, and treatment—paired with scientifically sound protocols—to empower poultry farmers to respond with precision, minimize losses, and achieve healthy, sustainable poultry production.

In the context of large-scale swine farming, the prevention and control of infectious diseases remains the pivotal factor determining the success or failure of operations. Porcine Reproductive and Respiratory Syndrome (PRRS)—commonly known as "Blue Ear Disease"—is a highly virulent infectious disease that poses a global threat to the swine industry; characterized by its rapid transmission, resistance to eradication, and high pathogenicity, it consistently inflicts severe economic losses upon pig farms year after year. Deeply rooted in the field of veterinary pharmaceuticals and livestock health, AGOVEE focuses on addressing the critical pain points associated with disease prevention and control in pig farms. To this end, the company has developed specialized prevention and control protocols specifically targeting PRRS, empowering livestock producers to precisely combat viral invasions, fortify the biosecurity defenses of their farms, and stabilize their farming revenues.

Infectious Bronchitis (IB) in poultry is an acute and highly contagious respiratory disease caused by the Infectious Bronchitis Virus (IBV), which widely affects chickens, especially laying hens and broilers. The disease not only causes respiratory symptoms, but may also cause decreased egg-laying performance and kidney damage, causing significant economic losses to the poultry farming industry. This article will introduce in detail the etiology, symptoms, diagnosis, and scientific prevention and treatment options of infectious bronchitis in poultry to help farmers effectively deal with this disease.
