New technology requires great teamwork
Anita Heeg and Glen Blier for Progressive Dairyman

Over the last decade, one of four farms in Canada to milking methods have changed be using the technology along substantially.

Together with its herd hand, we now have the ability veterinarian, Dr. Glen Blier, the to choose between a variety of Heeg family has summarized milking methods – from tiestall some of its experiences with setting, to parlour milking and, Herd Navigator over the as of more recently, robotic past year in the following milking.

Heegstee Farms and its herd veterinarian Dr. Glen Blier have developed protocols based on Herd Navigator alarms similar to the example insemination protocol shown here. These protocols can be written into the software so when an alarm is triggered an automatic action is generated and displayed on a list of cows needing attention.

An Evolutionary Analysis of Pre-Play Communication and Efficiency in Games Kenichi Amaya∗ November 17, 2004 This paper studies the effects of pre-play communication on equi- librium selection in 2 × 2 symmetric coordination games. The playersrepeatedly play a coordination game preceded by an opportunity toexchange payoff irrelevant messages and gradually adjust their behav-ior. In short run, the players' access to the actions of the coordinationgame may be restricted. While the players can revise the set of acces-sible actions only occasionally, they frequently adjust their behaviorin the cheap-talk game, taking the set of currently available actions asgiven. We obtain an efficient-equilibrium-selection result if the under-lying coordination game satisfies the self-signalling condition. On theother hand, if the game is not self-signalling, both the efficient andthe inefficient equilibrium outcomes are stable.
