ok here is the situation, as most know we had our 1st litter last sunday, making them 6 days old today. on day 3 it got very cold & i thought they got chilled, i found one down just laying there with tremors, i brought it in the house & got him warm & back on his feet & installed a light in the farrowing pen so it would not happen again. he was fine for a day & then he jsut went strait down hill till all he could do was lay there & squeal. I finally had to put him down because it was jsut to painfull to watch him suffer. all the others are running around fine & healthy i mean really fine ,, then the next time i go down to the pen bamm one is limping or carrying it's right back leg funny. then the next time i go down it can't even walk anymore. I have gotten a milk replacer & an trying to get them to eat on that hoping that it is just a shortage in momma' that is causing this. yesterday it was only 1 ,, then this am i find a 2nd one & now tonight on my last trip down there is a 3rd & the only thing i can see is the 1st stage is it starts to limp or carry it's back right leg funny. then by the next morning or night it is like there back end is parilized & they can't walk at all. can anyone help with this at all ,.,,, it would be greatly appreciated.
