a good sow is the so-called F1-a cross between a pure landrace and a pure largewhite...

and F1 bred with either a Pure Duroc or a Pure Pietrain or a cross between a Duroc-Pietrain Boar will give you the so-called Triple cross pigs which is a good pig for slaughter...

well, the Bureau of Agricultural Statistics need not survey or make sample survey of the animal population of each sample area....all they have to do is to get those information from the Municipal Agricultural Office of each cities and municipalities and compile them to get the real picture of the animal population, and not extrapolating them...i have contacted some municipal agri officers and they have the information on animal population, on a monthly basis...

hope to see you there...

Purina/Cargill is one of the feed companies in the country that is starting to have a set of records for the backyard...we've been contacted by them since last year to conduct seminars and train backyard swine raisers on proper recording...

ok po...salamat po ng marami...

hoping that the Bureau of Agricultural Statistics review their pig population matrix and i think their matrix is a little bit outdated already and how they get their sample field data...just to consider that pig population in Calabarzon accounts to 1.6 M hogs...i know a farm in Rizal having a sow population of around 20T with at least a total population of around 200,000 pigs for just one farm.....

hope to see you on april 2 if you have time to attend the meeting....

we planned that project 3 years ago but until now it can't materialize due to the limited data to be gathered on a backyard scale...if you know backyard farms doing recording of their production maybe we could collaborate with the foundation and work things out so that production performance on a backyard level can be made....

that's a very good project you will have just like the ones we are monitoring in a commercial scale..hope that you can get as much information and got some good results coming from the backyard raisers...maybe you could collaborate your proejct to the PSIRDFI-Phil. Swine Industry REsearch and Dev't Corp. as to how to get those information from backyard raisers considering most of our backyard raiser seldom record the performance of their pigs....

The 2007 Production performance will be released on April 2, 2008 at PCARRD, Los Banos, Laguna...You can attend the said meeting at PCARRD free...just call up the project staff Mr. Mike Torte at tel no. 049-5360014 to 20 local 236 and register your farm and be updated as to what happened to our swine industry last year....

thanks nemo for adding me up to the forum...
