What is the ideal weight for slaughter if you want good pork not bacon. I have just measured my gilts and they are 95 x 100 cm and I make this around 123 lbs please correct me if Im wrong. I was going to take them in a weeks time would they have put a few pounds on in aweek (is there a formula for knowing how much weight they put on at various ages). Also what pecentage do you actually get when butchered excluding trotters etc.
Thanks

is that live weight your talking ?
if so they are on the light side, we usually work on a 72% ish kill out ratio.
i would be looking at a minimum of 120lb DW but we take ours to about 140 - 150lb of boxed meat this gives a good eyeto the chops

what age and breed are they ?

They will be 24 weeks when I intended taking them in and they are OSB x GOS. I have found when I have taken them to 26/27 weeks they tend to be too fatty. How much do you feed yours in the final couple of months and what age do you slaughter.
Thanks

They should be right to go now, an easier way is to measure around their chest behind the front legs if they're 38 inches+ send them, i aim for 40 inches for a porker, 45 inches for a baconer. From one porker i get back 2 boxes inc sausages about 23 - 24 kg each box, i do not do trotters, heads, or anything squeamish but thats me! I measure mine as above 4 wks before their butcher date and gauge food by that, i aim on an inch growth a week so based on what they measure i up or down their food. Sorry its not very scientific but works for me.

ps we had the same cross go at 31wks and had an inch & half back fat. Whoops ;D

just checked my weigh charts we had our first osb's killed at 24 weeks they killed out boxed meat not dw 120lb - 122lb these were the youngest osb's we took we wanted to check fat level was ok all the others went to 26 weeks.
i make no secret that i am not keen on x traditional breeds as past experience has proved they do tend to take on more fat than pures and i like to keep pure.
as for feeding i feed slightly different to a lot of people we ad lib until 8 weeks then they go on 4lb a day each right through this gives us a good sized evenly grown pig we do the same method for the show pigs too, you may get the odd pig that needs a little extra then its done by eye. anyone that has seen my pigs in the ring may well think they are over fed but thats how i get them there.
you did not say if that was LW or DW

There's a calculation for their weight - measure in meters for this one ;)
Girth squared x length x 69.3 = weight in Kg
0.95 x 0.95 x 1 = 0.9025 x 69.3 = 62.5Kg (or 65.8 if the measurements are the other way round)
We normally aim for between 70 and 85Kg liveweight for them to go and I reckon on getting about half the liveweight back in joints and cuts.
Deadweight drops to between 70-80% of the liveweight, and weight of cuts is normally 70-80% of the deadweight.
For feed, I'd be tempted to stick somewhere between 4 and 5 lbs per day, if they're lying around inside their arcs and not doing much because of the rotten weather you could stick to the lower amount.
