mastitis-metritis-agalactia

a syndrome which occurs in sows that have farrowed for 12 to 48 hours; abbreviated MMA. It is manifested by an indeterminate set of signs including anorexia, lethargy, fever, agalactia, swelling of mammary glands, constipation and a marked disinterest in the piglets. There is always a mastitis, most often caused by Escherichia coli, but a variety of gram-negative organisms can be involved. Metritis is a rare occurrence. Called also toxemic agalactia, farrowing fever.
