There is a certain area of my barn that gets wet pretty easily. The door leaks water there. It's a nice small area that the pigs seem to prefer for sleeping and I'd put in a lot of hay this winter. After the latest farrowing and having the sow and her piglets locked in there for a week the smell is overwhelming and awful. It's clearly anaerobic compost at this point. What should I do to fix it??? I'd like to bring it out of the barn but being preggo I'm having trouble doing more physical tasks right now.
One major factor is keeping the bedding dry. If the bedding stays dry, it alows the bedding to soak up and quickly dissipate the moisture in the waist products, keeping itself aerobic, while transitioning the waist to aerobic as well. Once the bedding gets wet, it reduces the air in the material itself from water logging, depending on how saturated, and compacts further reducing air supply. Once these things happen, the bedding becomes ineffective at quickly pulling the moisture out of the anaerobic waist products, and evaporating that liquid to maintain air supply within itself, while also through the dessication of the waist products, allowing the introduction of air to cause a conversion of it from anaerobic to aerobic within the waist.
You'll need to figure out how to stop that leak onto your bedding, to address your concern, and most likely need to put in new bedding.
You may also consider using free arborist woodchips, as a deep bedding litter. They will need to stay dry too, but may provide better air movement due to the shapes allowing larger air pokets and better overall airation under less then ideal conditions.
Justin Rhodes uses the deep litter woodchip method, and likes it. If you want to learn more about it, check out some of his YouTube videos on the subject.
I hope that helps gives you some ideas. Maybe you can also get a neighbor or friend, to help change the bedding, if you're not able to at this point.
