“…A ocorrência de deslocamento de abomaso em bezerros ainda é pouco documentada na literatura (Mueller et al, 1999). Apesar disso, DAE foi relatado em bezerros com mais de uma semana (Fierheller, 2002), oito semanas (Hawkins et al, 1986;Mueller et al, 1999), duas semanas a três meses (Oman et al, 2016) e associado a doenças respiratórias (Katsoulos et al, 2016). Já os relatos de DAD são escassos, sendo relatado em bezerros com menos de um ano de idade (Dezfouli et al, 2016) e associado à úlcera abomasal em uma bezerra com oito semanas (Altan et al, 2012).…”

Deslocamento de abomaso à direita em bezerro: relato de caso

Deslocamento do abomaso é uma paratopia que ocorre com menor frequência em bezerros, touros e novilhas, quando comparado com vacas de alta produção leiteira. Objetivou-se relatar o caso de um bezerro, macho, com três meses de idade, atendido na rotina hospitalar da Clínica de Bovinos de Garanhuns. Segundo anamnese, o animal alimentava-se de leite, pasto nativo, grama, xerém de milho e farelo de trigo (200g/dia). Entretanto três dias antes da baixa, foi alimentado com palha de milho, apresentando em seguida timpania ruminal, dificuldade de locomoção e aumento do consumo de água. As fezes estavam escassas, liquefeitas e amareladas. Caso único, num total de 30 animais. Os principais sinais clínicos observados foram apatia, mucosas congestas, exsicose grau III, moderada enoftalmia, abdômen tenso, com formato maçã-pera, à percussão auscultatória evidenciou-se um som de “ping” metálico, na região do 12º espaço intercostal do flanco direito. As análises laboratoriais revelaram teor de cloretos elevado, de 81,88 mEq/L; hemoconcentração, leucocitose, por linfocitose e neutrofilia, com desvio à esquerda regenerativo, além de hipoproteinemia. Em função do diagnóstico de deslocamento de abomaso à direita (DAD), foi submetido à laparotomia exploratória pelo flanco direito. Nesta condição, o órgão estava bastante distendido por gás e conteúdo líquido. Seguindo o protocolo terapêutico, o animal apresentou evolução clínica satisfatória, recebendo alta no quinto dia após seu internamento. Conclui-se que deslocamento de abomaso à direita é uma afecção grave e, apesar da baixa frequência em bezerros, pode acometer essa faixa etária, acarretando prejuízos ao produtor, e o que reitera a necessidade de prevenir os fatores de risco associados a essa síndrome multifatorial.

In the fetal development of animals, critical physiological and anatomical events influence the long-term health and performance of the offspring. To identify the critical growth phases of the fetal bovine stomach, we used computed tomography imaging on 30 German Holstein fetuses to examine the fetal bovine stomach in situ. Computed tomography allows the study of diverse parameters such as the volume of the stomach chambers in situ without the need for sophisticated filling preparation techniques. The absolute volume, relative volume, and monthly volume increase of each stomach chamber were determined. Computed tomography was a reliable method for in situ examination of the fetal bovine stomach complex from the third month of gestation onward. It was able to detect an abnormal position of the abomasum in 2 fetuses. The crown-rump length of the fetuses studied ranged from 9.5 to 89 cm (from 2.2 to 8.3 mo of gestation). Over this timeline, the changes in the relative volumes of the ruminoreticulum and abomasum were inversely related. Until mo 5 of gestation, the relative volume of the ruminoreticulum increased steadily, whereas that of the abomasum decreased. Thereafter, the relative volume of the ruminoreticulum became gradually smaller, and that of the abomasum became larger; by mo 8, the abomasum was larger than the ruminoreticulum. All stomach chambers had large increases in volume over the gestation period and we observed differences in development patterns and volume changes of the individual stomach chambers over this period. The largest monthly volume increase of the stomach complex was between mo 4 and 5 of gestation. In this period, the volume of the ruminoreticulum increased 43.8 times, that of the omasum 38.9 times, and that of the abomasum 30.03 times. Between mo 5 and 6 of gestation, the abomasum had another growth spurt, with a monthly volume increase of 10.4 times. These 2 time points in the gestation period may be critical phases of fetal development that should be considered in the management of pregnant cattle.

“…In previous studies, the form of the abomasum in cases of DA was based on frozen autopsy findings [ 12 ], radiographic images [ 7 , 17 ], ultrasonography [ 2 , 3 ] and laparoscopy [ 15 ]. In addition, it was reported that DA occurred in cows with insufficient feed intake and a decreased rumen volume [ 16 ].…”

To clarify the mechanisms underlying the development of displaced abomasum (DA), we repositioned DA in 12 cows by rolling and observed the course of redisplacement using X-ray fluoroscopy. Displacement of the abomasum was observed to follow three patterns: displacement to the left side of the abdominal cavity through the gap formed at the reticulum, atrium of the rumen and ventral sac of the rumen (n=7); displacement to the left side after cranial movement along the diaphragm (n=3); displacement to the right side after cranial movement along the diaphragm (n=2). These differences were considered to be associated with the rumen volume. To the best of our knowledge, this is the first study reporting the visual observation of the course of DA in dairy cows.
