DEAR SIR: I have followed with interest the articles by Aidan Brennan on crossbreeding in the dairy herd over the past number of weeks and I would like to make the following observations. The article begins by quoting a report from Andrew Cromie on his analysis of data from differing high-EBI dairy herds and drawing the conclusion that crossbreeding no longer delivered any advantage. This is in direct conflict with the advice as I understand it from Teagasc on crossbreeding and also with the comments of Frank Buckley who carried out that research.

The success of the Irish dairy industry is built on four strong legs.
