Sochipa rewards the best scientific work

As part of its recent congress where 85 technical papers were received.

The recent version of the XLVII Annual Congress of the Chilean Society of Animal Production, SOCHIPA 2022, was held with great appeal. The activity took place over three days, from November 29 to December 1 virtually.

This new version included the presentation of 85 scientific articles or technical summaries, presented by academics, researchers, students and professionals from the world of animal production.

SOCHIPA’s Annual Congress was organized by the INIA Tamel Aike Regional Research Center, in the Aysén region, with the participation of 130 professionals and students from the region, and the presentation of four foreign researchers during the symposium.

Regarding the experience that this activity left behind, the outgoing president of SOCHIPA, Osvaldo Teuber, said that it was a very good congress.

“I am grateful for the support we have received from our colleagues at INIA Tamel Aike and other regional INIA centres, the work of the various committees and our current 132 active and honorary members. We also acknowledge the support of our sponsors, Barenbrug, TCL, Ferosor, Agrosuper, Cooprinsem, Veterquímica, Empresas IANSA, Anasac, SG-2000, SQMC, INIA Educa and Watts, for their ongoing support and for the active participation of professionals and technicians of our sponsors, in the activities of our congress”.


For this congress, 85 papers or technical syntheses were selected, including 31 relating to animal nutrition and feed, 13 to genetics, reproduction and animal health, 23 to pastures and fodder and 18 to production systems and case studies. These works are evaluated by professional members of SOCHIPA and the best works are defined in each of the thematic tables, which will be awarded at the next 2023 congress, to be held in person in the city of Valdivia, organized by the University of Chile of South. .
