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, Postpartum Agalactia Syndrome, PPAS
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).
Only in lactating sows
- Loss of appetite.
- Can have fever.
- Mammary tissue is not well developed and/or it is reabsorbing.
- Mammary tissue can be well developed, but there is no milk production.
- It may show as an infection in the urogenital system.
Causes / Contributing Factors
- It is seen few days after farrowing (usually up to three days after farrowing)
- Older sows
- Excessive body condition.
- Lack of water.
- Bad design of the farrowing crates.
- Sequelae of edema or mastitis.
- Poor hygiene of farrowing crates and farrowing rooms.
- It is based in litter appearance, with hungry piglets and how the udder looks: with not enough milk, if the udder is "drying up" or it is a well-developed udder but without milk production.
Not good respond to treatment. Oxytocin can be used to help with milk let down. Use of antibiotics, especially penicillin, will have mixed results. It may be necessary to assess if piglets are getting enough milk or if they need to be fostered to another sow or weaned;Also asses if the sow needs to be culled and improve hygiene during farrowing; make sure sows have good access to clean water at all times. Implement a good feeding program during gestation to minimize sows having an excessive body condition at farrowing.
