Sorry if I was a bit naive and did not take on board that many have jobs , children and many other things to fill their day. It is of course a lot different when one has time on their hands.
In answer to the above question I too add nuts or a compliment flour to their veg, bread, eggs or potatoes. I titrate thir nuts based on what mix they are given. Nuts are reduced if they have protein from other stuffs. From October I have to cook up the spuds/swede on an open fire and I will add pig flour to swell overnight before adding whatever veg we have grown for them.
Pigs are very competative when they eat and they are also good at selecting what they can eat quicker and what has greater nutritional value. My 2 pigs eat at diferent rates so I lean over their trough and scatter nuts at different rates for each pig - this is not always succesfull though
. They eat from the trough twice a day, graze/root outside and get weeds, rosehips, apples, walnuts as treats. Although sisters the more energetic eater of the 2 is of course bigger. They will get Chestnuts and acorns soon ( and maybe some brewers grains) as I prepare them for a December kill.
So the bottom line is that I do not weigh their food as it is impossible to guess how much an individual actually consumes. I try and ensure each gets the same and I adjust what they get from feed to feed based on how they appear and what we have available. I can not control what the old ladies in the village feed them although they have all kept pigs and they know not to include the naughty stuff from their kitchens.
I am unsure if their growth rate is different to pigs fed on just nuts and I can determine the size rather than age that they are ready to be killed. The fat content seems just right for us. My neighbour, who breeds Limousin pink veal, must like it too as he has asked me to keep a pig for him next year.
Rather a long post but maybe this answers your question rispainfarm.
