as a pedigree breeder it never ceases to amaze me that people will breed from what can only be described as as crap pigs then claim that there lineage is pedigree wrong wrong wrong
with any pedigree litter the piglets are born then the first selection is on markings do they comply with the breed standard as per the type of markings that is associated with that pig
next selection process is underlines 12 14 or 16 evenly spaced teats even the boars by this time you will be lucky to have 2 or even 4 perfect pigs by 8 weeks the legs are asses-ed and the future growth of these pigs should be able to be identified your 4 could be down to 1 or maybe 2 by this time weaning
all piglets should be birth notified to keep that sows records up to date only the good ones should be bred from and registered also no use breeding from a piglet that its mother consistently has small litters take a chance if you want but better not spend your money on it when there are better available
feeding is up to the individual keepers low food input will give you low weight gain where as a feed at a higher rate the will grow quicker Finnish earlier and get to the boar earlier as well all at a cost saving to you
ideally you want them farrowing at from 11 months to 13 months
and if they are for meat that is where they should go none of this cutsie factor get them slaughtered you are not doing yourself any favours or the breed as you have posted already
Hampshire's are a big pig our boar is 345 kilos at 2 years old and that is not shovelling food in in fact he has spent the last month in a wood on 2 lbs a day of nuts and the Hampshire sow that was champion at westmoorland was nearer 450 kilos and very broad at both shoulders
not every pig can conceive or have active sperm
so once again a list for all
pedigree and check the paperwork
markings for that breed
underlines
feet and legs
litter size from both parents
temperament of sow and boar
have they won any shows or prizes
unless the above can get a full list of ticks you are only breeding crap to breed more crap
