I am paying £290 per ton for sow rolls from East Coast Viners Grain. I did contact several feed companies and they were the cheapest. I used to feed barley, potatoes and some sow rolls but this was costing more than just the roll feed. The pigs finished in half the time with feeding just sow rolls, had very little fat (as barley puts fat on) and I saved several hours of travelling with the tractor and trailer to Humbie, East Lothian to get the potatoes.
Weaners you use wheat and lupins, growers up to say 45 kg you use wheat, barley and lupins, Finishers to 70 - 100 kg you use barley and lupins. Barely prevents the fat from going on, lupins helps with digestion of a poor feed. If barley is fed straight with nothing else then yes all pigs will go fat. Add Soya meal and canola meal added to the feed in the mill and leave out the meat meals. Add minerals, lysine, salt and chrom-e-late. Pigs do well on this mix. Just have to adjust your barley lupins wheat on your different growths of pigs. You can also add molasses or/and tallow. This gives enery and keeps the dust down as well. Molasses has to be warmed so hot water added helps to mix it in the feed and get it out of the bucket. Tallow needs a drum heat to melt it or put it out in the hot sun to melt. Coconut oil can also be used and the same requirments to melt it. vegetable oil does not need melting so that can also be added to your feed....just depends on how set up you are at home.
