CGIL has a deep involvement internationally through the summer courses that have been offered, through courses given in other countries by CGIL faculty, through graduate students, and through joint research projects with researchers in other countries, such as with INTERBULL and GIFT (Genetic Improvement of Functional Traits), or ICAR (International Committee on Animal Recording). CGIL faculty have also served as external examiners on Ph.D. defenses in Sweden, Australia, and Ireland. Many species industries are international in their organization and CGIL collaboration with them involves researchers in other countries. CGIL members have also participated in many meetings in Europe (EAAP) and other countries (e.g. Brazil, Australia), as well as the World Congresses.
