Just picked up your thread again. In the Solomons we have climate difficulties for some European pure breeds and I expect other places in the tropics will have them too. Durocs, Large white and Landrace are better crossed with a bit of local pig somewhere in the gene pool. The growth and meat quality is excellent. I weigh every carcass I produce and Duroc has about 10% more bone than Landrace and Large White but crossses very well with either of the English breeds. The trace is Local pig gives better growth under local conditions.
Photo below of a recent piglet cross as above. Nice colour isn't it.
The body is nice and long for bacon and the ham is a good size too. Fat content just right for sausage and salami. All breeding is a compromise but this cross is just right for me. Second photo below of the litter.
There are 8 in there somewhere. 4 piebald piglets like the Large White/Local cross sow and 4 coloured like the Duroc/Large white cross boar. They are all doing well and taste delicious.
All the best,
