O deslocamento de abomaso e uma sindrome multifatorial que acomete bovinos de alta producao leiteira e pos-parto, neste, 90% dos casos ocorrem em ate seis semanas.  apos o parto, sendo que 90% dos casos podem ocorrer ate seis semanas apos.  Dos transtornos dos volvulos abomasais, o deslocamento de abomaso para esquerda representa de 85 a 96% das ocorrencias. O trabalho teve como objetivo avaliar os impactos economicos provocados pelos casos de deslocamento de abomaso em uma propriedade leiteira de alta producao. No periodo de um ano, foram acompanhados onze casos de deslocamento de abomaso (DA) em femeas bovinas da raca Holandes. As ocorrencias no 25° dia pos-parto corresponderam a 63% dos casos. Foi possivel verificar, quanto a producao de leite antes e apos a enfermidade, perda de 75,45%, com prejuizo diario de R$17,21 ou US$10.12 por vaca doente. No total, cada animal com DA dispendeu R$ 417,00 ou US$ 248.00. O retorno da producao normal de leite apos a cirurgia  ocorreu em media aos 14 dias. SUMMARY Abomasum displacement is a multifactorial syndrome that occurs in high performance dairy cattle, especially during the first 6 weeks after delivery. Left abomasal displacement (LAD) is more frequent (85 to 96%). This paper aimed at evaluating the economic impact of abomasum displacement on a high performance dairy farm. During one year, eleven cases of abomasal displacement in female Holstein cows were followed. Of all the cases observed, 63% occurred on the 25th day after delivery. We verified that the comparison of milk production between before and after diagnosis showed a 74.5% decrease, which represents daily losses of R$ 17.21 (US$10.12) per sick cow. Each animal with abomasum displacement costed R$417.00 (US$248.00). Mean milk production was recovered an average of 14 days after surgery.
