**9 Ask the VMD Leon Riegel Keep sows cycling A reader asks: What do you recommend to keep sows cycling properly in order to keep group farrowing schedules running smoothly’ Dr. Trayer comments: One of the major problems in total confinement operations is the continuing active cycling of breeding stock after the weaning period. We often find individual problems in herds that can he identified as management problems and corrected.

My general recommendations in any intensified farrowing operation is that every objective should be made in the farrowing room to keep the animal in as good physical shape as possible If she has farrowing problems, correct them and get them under control before she is brought back into the breeding area If she has MMA problems, a discharge, if she is low in body weight, increase her feed so she is consuming all she will eat and is putting on weight. If she is a thin sow and has a small litter, you may Brawny four-wheel for tough demands More traction Outboard planetanes with ad justable wheel treads boost traction by putting weight where it can do the most good Crab steering - included in exclusive Case 4 way solid state steering gives you 4 track traction (8 track with duals) to fight side pressures and drift and keep you moving straight ahead 4 way steering also lets you work hillsides and row crops the way other 4 WD's can’t Tim Trayer consider transferring the pigs to another sow, weaning the sow early, and giving her extra feed in the farrowing area or gestation area so she can rejoin the group at a later tune in good body condition. My philosophy in weaning is enough stress to bring an animal into a good heat cycle three to five days after weaning. It has been questioned but not proven that a three week wean is possibly too early for the reproductive cycle of the sow. Other methods used to make animals cycle include hormone shots, not the ideal situation.

Three pigs from each farm were slaughtered and the carcasses examined for problems that affect production costs and performance. The pigs were all healthy-lookmg specimens with plenty of muscle and low fat, but some cost more to produce than others Where were these extra hidden costs and what giving you problems So when you’re weaning a group of twenty, you can expect two to give you trouble by not cycling back properly. With that in mind, keep replacement gilts or previously non-cycling gilts available to make up the difference and work them into your schedule. drive Big capacity brakes for positive control The Case-built cab Many tractor manufacturers buy their cabs The Case Silent Guar dian cab is a totally integrated 4- post roll protected structure designed tested and built at our own multi million dollar cab manufacturing facility It's not only the strongest but also the quietest roomiest cleanest easiest to see f>-om cab we ve ever built on new Case 4-wheel drive tractors E.
