Farrow Pulse

Makes farrowing easier

Farrow Pulse is a new compound feed for sows before farrowing. It was created by the Vilofoss research team in 2017.

Its main objective is to reduce the number of stillborn piglets by providing a better muscle tonicity in sows. Farrow Pulse has also other interesting properties including an increase in milk production.

The principle of Farrow Pulse is based on a drop in dietary electrolyte balance (dEB) of 100 units by adding calcium chloride.

At farrowing, the sow mobilizes calcium in the blood to strengthen muscle contractions. Calcium is also necessary to start and maintain the milk production. A lack of calcium availability increases the risk of long farrowing duration and reduces the milk production.

A decrease in sow feed dEB of 80 -100 units contributes to stimulate the release of calcium from the bones - compared to gestating feed 5 to 7 days before farrowing.
Furthermore, it decreases the pH of urine and thus reducing the number of bacteria in the urine.

These different effects are contributing to less stillborn piglets.


Benefits of Farrow Pulse:

  • Farrow Pulse makes farrowing easier for sows
  • Less stillborn piglets
  • A better start in lactation
  • A better weaning weight
