This pathology consists of inflammation of the udder (mastitis) and inflammation of reproductive tract (metritis) resulting in a poor milk release or reduction of its production (Agalactia).

Alternative names: Mastitis, metritis, agalactia, MMA, PPAS

Information

This pathology consists of an inflammation of the udder (mastitis) inflammation of reproductive tract (metritis) resulting in poor release of  milk or reduction of its production (Agalactia). The etiology of this condition has not been identified but suspected to be multifactorial.

 

Symptoms

Lactating sows

  • Loss of appetite.
  • Can have fever.
  • Mammary tissue is not well developed and/or it is reabsorbing.

  • Poor hygiene of farrowing crates and farrowing rooms.
  • Possible viral infection?

Diagnosis

  • It is based in litter appearance, with hungry piglets.
  • Sow udder is "drying up" or it is a well-developed udder but without milk production.

Control/Prevention
