The lato sensu postgraduation in Animal Health, after five years of offering by Preventive Veterinary Medicine Department (DMVP), resulted in the stricto sensu modality at Londrina State University (UEL). Such consolidation occurred due to the maturity of professor’s staff. In 1991, a proposal for a master\’s degree course in Animal Health was sent to the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES). After approval, the first class began in 1992. Since then, over the years, the course has undergone some adjustments, particularly to accommodate new professors, new lines of research, new concentration area and, mainly, new realities to the labor market and insertion of professionals in the field of agricultural sciences in the context of teaching, research, development, technology diffusion, service provision, commerce, and industry. In 2002, the Postgraduate Program in Animal Health Science at the Londrina State University (PPG-CA/UEL), had its biggest and main restructuring. With greater scientific maturity and professional ascension of the group of professors responsible for the master\’s course, and partnership with professors linked to the Department of Animal Sciences, and Veterinary Clinical Sciences from UEL, it was proposed to open the doctoral level. Thus, the doctoral proposal was formatted with two areas of concentration consisting of the areas of Animal Health and Animal Production, it is noteworthy that already at that time the PPG-CA had glimpsed the need for union between the departments to solidify the PPG. Based on this proposal, the Program is no longer linked to a single proposing department, the Department of Preventive Veterinary Medicine, but also to the Department of Animal Science. In addition to uniting the departments, the proposal included, in the Animal Health concentration area, some colleagues from the Department of Veterinary Clinical Sciences, who developed research with an interface in Animal Health. Considering the great increase that we obtained both in quantitative terms and, mainly, in qualitative terms concerning research and development actions, which contributed to the consolidation of the program, this is still our current format. After our consolidation at the national level, represented by concept 5 (from 3 to 7) attributed to the Program by three consecutive three-year evaluations, the Program\’s coordination directed efforts towards increasing actions to promote the Program\’s internationalization. In the 2010-2012 triennium, the Postgraduate Program in Animal Science made its greatest qualitative leap. After 22 years of intense research, teaching, and extension work conducted in the context of the program, and mainly, after the maturing of the faculty and the effective consolidation of our Research Lines and Areas of Concentration, our efforts were valued by CAPES. In this triennium (2017-2020) we achieved the much-desired recognition of our actions developed both nationally and, mainly, internationally. With this recognition, we were awarded concept 7, the highest CAPES concept attributed to those Programs consolidated with a strong national expression and with research actions and international exchanges.
