Another Farm's Farrowing Perspective

Frequent commenter Donna O'Shaughnessy has been following along with my ramblings on winter farrowing and took the time to discuss her farms farrowing/breeding plans on a post at her blog called Midlife Farmwife. Their farm is in Illinois and pretty much straight east of my farm, so the weather patterns will be similar to what I'm facing ... which made this information very intriguing. The post titled, "Farrowing Follies" details their farms handling of sows from breeding, gestation, farrowing, and weaning (among other details). There are also good pictures to give you an idea of their set up!

If you are interested in the e-huts that she references here are some plans from Practical Farmers of Iowa. I also like her "hogciendas"and have been thinking about building something like that. Even if I ended up with a different sort of farrowing system they would be great out in the woodlots or for sheep in the winter. Basically I just need more portable buildings that I can drag around with the tractor!

Thank you so much for putting together such a great post Donna!

Winter Farrowing :: Huts and Hay

Winter farrowing has been on the forefront of my mind lately (in case you haven't noticed), and as I look at the 8-day forecast and see highs around 30ºF the many ideas I have keep tumbling around in my mind. So far I've talked about traditional hoop buildings ... greenhouse type hoop buildings ... and of course using a deep bedding system in either option. If you read my post last Friday you were introduced to Becker Lane Organic Farm and the report he did on his greenhouse farrowing building (with in-floor heat). But, as I made my way over to his website and Facebook page I saw the picture above (here is a link to the description of that picture from the Becker Lane Organic Farm Facebook Page). A quick e-mail to Mr. Becker led me to the knowledge that they now farrow outside year-round in insulated huts either made by, or similar to, Booth Pig Equipment huts.

Which all led me to thinking ... maybe a building of any type isn't my solution ... maybe I just need some big straw bales, a wind break, and some insulated huts. In fact Mr. Becker's farm does not even use heat lamps in his huts so he is only using the work of the insulation, bedding, and the sow's body heat. I don't know why I haven't thought about this more since I have known that Mr. Walter Jeffries of Sugar Mountain Farm has been writing about outdoor winter farrowing since at least 2006. You can read about his experience here ... and here! The great thing about Mr. Jeffries posts is that at the bottom of the posts he gives you the outdoor temperature, so you can tell that it is working in cold conditions.

There are multiple things running through my mind as I think more about outdoor winter farrowing. I worry about mud because as you can see in the picture above those sows only have a little area in front of the hut and in the freeze and thaws of our winters in Southern Iowa that space could become very muddy. I can also see that protection from wind and precipitation would be very important to weaning a good number of pigs from each litter. But, in my mind one of the most important things would be good mothering sows. I think it would be important to have sows that were very careful and caring with their pigs in order to protect them from crushing.

Pretty much all that I have decided after a few weeks of obsession over winter farrowing is that I just need to get out there and explore different options that farmers are using in my state. So, after the holidays I hope to do a little "tour" of some different winter farrowing set-ups. If you happen to be in my area and are willing to let me stop by I'd love to hear from you. Or if you wouldn't mind doing a "virtual tour" and sharing it with others on the blog I'd love to hear from you!

For now though ... does anyone have any thoughts on or experiences with outdoor winter farrowing?

Greenhouse :: Hoghouse

Inside a Farrowing Greenhouse at Becker
Lane Organic Farms.

Do you ever find yourself answering your own questions? On Wednesday I wrote about how (with expansion in mind) I thought it was time to add a hoop building to the farm for winter farrowing and winter housing for the grower pigs, but the thing that had always been holding me back was the thought of keeping the building empty for the spring, summer, and fall as the pigs are out on the pasture. Then I randomly found a three-ring binder from the "National Conference on Hoop Barns and Bedded Systems for Livestock Production" (nice short name huh?). As I thumbed through the material I came upon this little tidbit in the "Alternative Systems for Farrowing in Cold Weather" booklet ... "Greenhouse with Radiant Tube Heating".

You can read the article that I came across by checking out this .pdf and scrolling down to page 9. A little more searching turned up this gem from Jude Becker of Becker Lane Organic Farm. The second link there is really a great summary of data and pictures of his greenhouse/hog house construction. Mr. Becker's building was quite a bit more advanced than I was contemplating with it's in floor heating and wood boiler, concrete floor and walls, and eventually it was divided into quadrants with a feeding system. You will also find that his results were much less than stellar, but I think it does give me something to think about for the future.

Some time ago I watched a video online about a farmer that was using a traditional hoop house for winter farrowing. He was using deep-bedding and his pasture huts for farrowing, but also had a heat lamp in the creep area of each hut and a radiant heat tube hanging at the peak. This particular farmer said his goal was to keep the building slightly above freezer so that the sows would be forced out of the common area and into the huts for farrowing. In my somewhat warmer Southern Iowa climate having two layers of plastic with air between them (provided by a fan) may help keep the main area around that 32º some or much of the time.

There are always downsides to every system though. Many of the fabric hoop house owners that I have spoke with tell me that they have had the same tarp on their buildings for 15 years and some even longer. With the plastic I'm sure it would have to be replaced much more often than that and there would be costs and labor associated with that. The benefit that has me most interested in this system though is the ability to have a secondary use for the building in the summer ... by growing some sort of crop once the pigs out out! Of course there is no real "need" for a greenhouse when I would be using it, but maybe I can figure out something instead of having an empty building.

I would love to have a discussion on this topic, or hear any thoughts you all have on the viability of this type of building. Plus ... if you have any suggestions on crops that could be raised in the building ... well ... I'm open to suggestions!
