The Integrated Doctoral Program in Animal Science (PDIZ), currently with Concept 5 in the CAPES assessment (2017), was created from discussions among the Federal Rural University of Pernambuco (UFRPE), Federal University of Paraiba (UFPB) and Federal University of Ceara (UFC), considering the need to achieve the training of highly qualified human resources, at the Postgraduate level. It was an original idea that had been discussed since 1996 by the UFC, UFPB and UFRPE and the Coordinators of the Postgraduate Programs in Animal Science, at the Master's level of these three institutions, which presented to CAPES, in 1999, a proposal for the creation of the Integrated Doctoral Program in Animal Science (PDIZ), having been approved in the same year.

In 2018, UFRPE requested its disconnection from PDIZ, aiming the creation of its own doctoral program. From 2019, PDIZ was composed of UFC and UFPB, mantaining the aims and goals of PDIZ within the period, as well as the objectives of its creation.

The PDIZ started teaching activities in 2000 with the Program’s General Coordination under the responsibility of UFRPE. Every four years, in a sequential manner, the PDIZ Coordination has been transferred to each one of the Universities, thus that all participate administratively in the conduction of the Program, providing an understanding of the management process and the operational characteristics of an integrated program and contribute to a better resolution in relation to administrative and academic improvements.

The PDIZ concentration area is in Animal Science with the research lines: feed evaluation and feeding systems for ruminants and non-ruminants; biotechnology and animal physiology; nutritional requirements for ruminants and non-ruminants; animal breeding; forage plants: ecophysiology, production, management and conservation; systems of production, management and animal ethology.
