Sorry i dont have a detailed comparative...
Just to give nalang an idea.

3 to 5 times na much expensive ang tunnel ventilation. Ang return ng investment almost 2times katagal.

Ang mortality is less and mabilis naman lumaki ang animal...

Medyo matagal bago ang roi pero pagnakuha mo na almost 2times naman ang kita mo afterwards....


So far kasi marami pang handsoff sa system na ito kasi nga sa laki ng puhunan...

Thanks Doc but do you think that the ventilated system ay mas ginugusto ng mga contract growing companies kaysa sa conventional?  If so, bakit naman kaya?

Hi Doc and everyone.  I'm new here in this site and I have been trying to search for a true to goodness information that readily gives a comparative study between the pros and cons of poultry farming in a tunnel ventilated house as against a conventional open type house.  I hope any of you can help me on this please.  Thanks in advance...
