A blessed day, gentlemen. i'm Paolo, an office employee residing in Pampanga & i'm very much interested in this DBS system. I've started my backyard piggery this year as a second source of income. I started with 7 fatteners, sold 6 of them & decided to keep the one female pig para ipa AI at paanakan. My pig pen has an inclined concrete flooring & relatively small (approximately 2m X 4m) & i would like to ask some advise to convert it into DBS, whether to remove the concrete flooring, or to push thru in putting the recommended apportionment of the rice hull/sand, etc or if it would be ideal to expand it. Since we also have mango trees in our area, is it advisable to use mango leaves as bedding? Also does DBS really prevent/reduce the pig odor/smell occurence? I'm also wary of neighbors who would complain due to the smell, especially when the time comes when the sow would give birth by Jan 2011. During the time of the 7 fatteners, i got some complaint (from 1 neighbor) about the smell, although i've been religiously keeping the pigpen clean (using the "dakot system) & kami mismo, wala naman kami naaamoy. Is there a certain "radius" or periphery" so that the pig smell would not reach the neighbors? Looking forward to your advice as this will really be a big help. My deepest appreciation. - Paolo
