Dear Mr. Gavin,

It's a very interesting topic and there is much to lern from it. Thanks for sharing it. Very recently I met Dr. Tilak Dhiman, of Diamond V from USA, in India and just today i have placed an order for the XPC to be used very first time in my farm. I have been using Yeasec and Actisef regularly, so let's see how the XPC performs at our place.

By the way, i couldnt see all the graphs illustrated in your above report, would you be kind enough to send me this complete report along with the graphs in a mail to me at -

Thnaking you in advance,

With Regards,

Hello Gavin,

interesting data with some good comparisons & with some large data sets.

Just interested to know how you created the Survival graph of DOPN for Lact=1 (blue line) with Lact>1 (red line), how have you set that up in D Com 305?

Also is there a command to show a sum by AAFC i.e. 23 months AAFC total milk produced in Lact 1?

Thanks Patrick.
