PDF Assignments

Ignacy Misztal (UGA), Shogo Tsuruta (UGA), Daniela Lourenco (UGA), Yutaka Masuda (UGA), and Ignacio Aguilar (INIA, Uruguay)

The course can be attended in full or partially. The attendance in Weeks 1-2 is limited to 25 and in Week 3 is limited to 35. Those attending for 2-3 weeks will have priority.
Those familiar with basics of Fortran 95 can skip Week 1. Those familiar with the BLUPF90 software can skip Week 2.
Thursday-Friday of Week 2 and Week 3 will involve very limited programming and can thus be attended only by those interested in application programs and genomic applications.

Participants are expected to be familiar with mixed model equations and quantitative genetics.
Familiarity with Linux / Unix environments a plus.
Knowledge of programming in any programming language a strong plus.

The fees will be the same regardless of the number of weeks attended

• Industry - $1200
  
• Academic - $700
  
• Graduate student - $500
  
• Graduate students from USA who are part of AG*IDEA institution - no fees
  
• Prospective graduate students please contact Daniela Lourenco (danilino@uga.edu)

Picnic in Summer Course at UGA’s Animal Breeding and Genetics is a chance to relax in beautiful nature Georgia. On May 25th, casual outdoor evening was a great opportunity to gather with new friends. Attendees shared and enjoyed a fun and memorable experience at Sandy Creek Park.

Animal Breeding and Genetics Team had 51 attendees from all over the world to join UGA Edgar L. Rhodes Center for Animal and Dairy Science for a 3-weeks summer course. Many attendees said the team’s lectures and assignments have helped to understand about the newest methods of animal breeding and genetics. During the summer course, participants, who embrace same passion for animal genetics and breeding in different species and countries, exchanged opinions and listened to each other through social activities such as Picnic in Sandy Creek Park, Gala Dinner at Terrace Room in State Botanical garden of Georgia, and Beer brewery tour for Terrapin.

“I was happy to have been able to create a bond with many scientists in my filed,” said one of the participants. “I learned the most advanced system for animal breeding with their computer programs.”
