Pigs # 15 - The Tymawr Pig Company!

We're full of enthusiasm now, having had great success in the last week with 'farm gate' egg sales, we're missing the pigs and their area is greening up nicely after the application of 'green-manure mega-mix'! These three factors combined mean one thing: we need to put together a plan to buy a LOT more pigs, get organised with our marketing and production and go for it!

There is around two and a half acres of woodland here at Tymawr Farm, and we plan three uses for it:

1. Woodland pigs
2. Yurts / luxury camping
3. A firewood supply (the low capital, high efficiency solar solution!)

We aim to improve the woodland whilst using it, by which I mean: clearing brambles and dead wood to allow air and light into the canopy and the tree-bases, feeding the soil and improving it's texture, and, gradually improving the demographic of the tree species, eliminating any softwood or 'weed trees' like elder or hazel, and increasing the proportion of high-quality timber and firewood trees like Ash, Oak and Cherry.

The Woodland pig element will consist of small paddocks, each containing three weaners, of around 200 sq.m size, and with a pig house of approximately 3 sq.m in size (internal space), with a roof size of 4 sq.m. Each pig can drink up to 1.5 gallons (6.81 litres) water per day http://www.thepigsite.com/articles/3/feed-and-nutrition/1610/). As we don't have mains water in all areas it would be great if the pig's water could come from the roof - we have an abundance of rain water in this part of Monmouthshire!  Using data from the met-office (see below), and assuming an 'opening stock' (IBC?) of 500litres of water, 'self contained' pig-paddocks like this are definately possible.

Each acre has 4050 sq.m in it, assume 20% is lost to pathways, that leaves 4050x80%/200 = 16 pens.  Therefore if we can turn 1 acre of the 2 1/2 over to pigs, leaving another acre for luxury camping / yurtage, we can keep 48 pigs in relative luxury!  As we aim to buy at 10 weeks, and slaughter at around 30 weeks, we should be able to process 2 batches per year in our woods.

In each paddock I'd like to fell 30% of the trees, logging them up for firewood, and after the pigs move on, having left lots of lovely manure and urine, I'd replant them with high quality replacement trees.  The aim would would be to eventually create a surplus of wood for sale, ideally as timber for carpentry and joinery.
