“…More and more scientists group the discorders connected with farrowing under the heading of MMA, mastitis-metritis-agalactiu (THURMAN and SIMON, 1970;MARTIN, 1970;MIDDLETON-WILLIAMS, 1977;GOONERATNE et al, 1982;BLOOD et al, 1979;BACKSTROY et al, 1984;JORSAL, 1986;FURNISS, 1987). Finally one sometimes talks more generally about "dis-orders at farrowing or during post partum phase" (JONES, 1971;PETERSEN, 1983;AMTS-BERG, 1984; CARR, 1990). Such disorders affect piglets in the form of diarrhea, hence the vocable "mustitis-metritis-diurrheu complex" which is also used (SMITH, 1965).…”
