Mr Hog,this idea of yours about enclosing your barn will not work out,tried it back in 2005,the hogs will overheat and die,if you can afford airconditioning it will work along with proper ventilation,air must  circulate so many times per minute so much volume per hour.The idea you have about a large chimney,sounds good,thought about this myself,was thinking about buying 45 gal. drums,welding them together,the first drum would have charcoal and as the exhaust air was forced through should help mask the ordors,just something I was playing with some time ago.Remember animal manure helps pollute and create green house gases,we should all do our part and help the enviroment,

Hi mr mikey you have some good ideas I just have to keep it in mind plus have a plan just in case people starting moving in on are piggery.Its to bad but land is getting all used up on housing as the population is getting bigger and not enough for farming people have to eat.I will be looking into biogas to run all the fans and airconditioning and to run all the lights .So I will need alot of help maybe I sould try to find someone to hire in davao to do such a job.

Mr Hog, Just an idea,

Autogasmanila do convertion of gasoline engine to lpg run engine. Since lpg and biogas is somewhat the same why not ask this company if they can fit your farm with a convertion kit which uses biogas.
In theory i think they would not have any problem at all fitting it to your needs.

So, the next problem you need to address is fitting the engine to the generator. But i do think you can solve it much easier.

Mr Hog,do not worry,the Philippine Govt. knows in 20 years they will need all the food they can grow/produce,you are right as the population grows the demand to feed the masses will increase,us farmers will be sitting on a gold mine.Total enclosure and equipement will cost a fortune to build and operate,some in the Philippines are looking at bio diesel,looking into this myself right now,major oil companies buying land in India to plant jatropha as a fuel source,they say 1 hectare will produce approx. 3000 litres of bio diesel,this plant grows in the Philippines.The cheapest way right now would be to make a big sign and put in front of the farm by the road so everyone will see it, COMING SOON MAJOR EXPANSION.Should the land next to you sell,the buyers have advance notice you will expand the business,buyer beware.Relax man,you will worry yourself to death.

P.S. would be nice if you started calling Nemo D.V.M. as Dr. Nemo,all vets in Canada like to be refered to as Dr. first.he is a educated man and we should show him some respect.

Mikey and everyone it is okay if you just call me by my handle Nemo.  Do not get me wrong mikey, i do appreciate you calling me Dr. 

I would like to be respected as a person rather than because of my degree. For me it more uplifting.

I do not want to sound melodramatic but i do believe that respect is earned by respecting others and not by earning a degree, money or a position in the government.

Dr Nemo and mikey thankx for the info again.I just wish I could go back to my farm and do some work there..But I have many bills to pay here in canada when my farm is big I sure will be going back much more often.By the way mikey did you get my private message?

Dr,your too modest.  mikey

Mr Hog,sorry I did not realize that someone sent me a message,sorry will check now,hard to operate a business when you live half a world away,I am sure you can understand,am busy with my goats right now,they need my attention now,rainy season always a problem time for us with the goats.
