Simple SummaryThe present study evaluated oxidative and antioxidant status in dairy cows with Left Displacement of the Abomasum (LDA), an economically important postpartum disease in cattle. The oxidant capacity of plasma measured with a test fo reactive oxygen metabolites, the d-ROMs test, was significantly higher and the plasma biological antioxidant potential (BAP), measured with the BAP test was lower in the LDA group compared with the control group. Oxidative status was assessed using an arbitrary index obtained from the ratio between d-ROMs and BAP and the results showed that cows with LDA experience an imbalance between oxidants and antioxidants.AbstractLeft Displacement of the Abomasum (LDA) is a condition that occurs in high-producing postpartum dairy cows and it causes economic losses. Studies performed in the last decade indicate that adult dairy cows experience oxidative stress. Increasing interest in the role of oxidative status in ruminant medicine has emphasized the need to develop reliable methods to assess it. A few studies have evaluated the relationship between LDA and oxidative status, mostly through the determination of single parameters of oxidation and the determination of antioxidant status separately, with contrasting results. The aim of this study was to assess the oxidative status by the measurement of Reactive Oxygen Metabolites with d-ROMs and Biological Antioxidant Potential BAP and the calculation of the Oxidative Status index in 74 multiparous dairy cows with LDA. Each case was matched with a control herdmate. The amount of free oxygen radicals in plasma samples was determined using the d-ROMs test, the concentration of antioxidants was measured using the BAP test and the Oxidative Status index was also calculated. The concentration of d-ROMs was significantly higher in the study group compared to the control group (179 ± 37.7 U CARR and 158 ± 23.0 U CARR, respectively), while the concentration of BAP was significantly lower in the study group than in the control group (2156 ± 98.1 µmol/L vs. 2558 ± 108.5 µmol/L). The Oxidative Status index value was significantly higher in cows with LDA than in healthy cows (8.3 ± 1.51 vs. 6.2 ± 0.76). The results of this study indicated that an inbalance between oxidants and antioxidants occurred in cattle with LDA.

“…Cows suffered from LDA, exhibited clinical signs of anorexia, weakness, drop of milk and scant feces, which agree with other results (17,23,26,27), these occur due to inhibition of rumen abomasal motility as a result to impairment of the enteric nerve system which cause defects in digestion of food material and then lack of volatile fatty acids (5). Ping sound heard on the left abdominal wall during percussion with simultaneous auscultation at the upper third of the 10 th , 11 th and 12 th intercostal spaces, it confirmed by Van Meter et al, Aly et al and Ismael et al (8,17,26), although a ping sound could originated from gas trapped as in the ruminal atony or may be obscure for little time after traveling to the clinic, it consider the characteristic clinical signs, re-examination after 24 hours was important to confirm the diagnosis, in LDA a ping sound originated from gases trapped in displaced abomasum (7,27).…”

“…Temperature and pulse rate will have increased in acute case and subsided to normal range in sub-acute affected cows, although fever occurs in concurrent diseases such as mastitis, metritis (7). From results, rumen contraction was decreased which agree with Aly et al and Ismael et al (17,26) hypomotality of rumen could be due to concurrent subclinical hypocalcaemia or depression from concurrent inflammatory process (1).…”

“…Clinical examination of LDA cows revealed a rise in temperature and heart rate, these results disagree with Dezfouli et al, Aly et al, Ismael et al and Ghazy et al (1,17,26,27).

The aims of the current study were a definitive diagnosis of left displaced abomasum by using ultrasonography furthermore determination of abomasal position and measurements. Study includes sixteen local cattle breed, six have anorexia, weakness and drop milk production, on clinical examination there was decrease rumen contractions 3.6 \ 5 minutes, furthermore a pinging sound heard on auscultation of left intercostal spaces there were diagnosed as left displaced abomasum, other ten clinically healthy cows considered as normal control group. Ultrasonographic imaging was performed for stand nonsedated cows by use 3.5-5 MHz transducer at the ventral midline and in the intercostal spaces 9, 10, 11, and 12 from the left side. Ultrasonography revealed a left side displaced abomasum to an area between the abdominal wall and the rumen, which appeared as hypoechoic fluid content ventrally and hyperechoic parallel echogenic lines of gas gap dorsally, abomasal folds appear as filiform echogenic lines. While in healthy cows an abomasum located in the ventral midline and directed mainly to the right side. In conclusion, ultrasonography as a non-invasive technique could be used as a confirmative diagnosis of left displaced abomasal and help for differential diagnosis of left abomasum displacement a well as can be useful for measurement of abomasum in healthy local breed cattle.

“…Apatia, desidratação e polidipsia também são evidenciados. Fezes pastosas e escassas, diarreia contendo partes de grãos, cólicas e odor cético no hálito (Ismael et al, 2018). Os parâmetros vitais permanecem dentro da normalidade, exceto em casos onde há exacerbada produção de gases culminando em compressão do diafragma.…”

Durante o período de transição em vacas leiteiras caracterizado como sendo o intervalo de três semanas antes e três semanas após o parto, os animais são acometidos pela grande maioria das enfermidades. Em suma, cerca de 70% das doenças acometem o gado leiteiro neste lastro de tempo. O deslocamento de abomaso é umas das enfermidades que podem ocorrer durante tal período e consiste em uma das paratopias mais frequentes no gado leiteiro que culmina em onerosas perdas econômicas, uma vez que se tem custos adicionais com tratamentos, redução da produção de leite, perda de peso, aumento no intervalo entre partos, descarte do produto lácteo e, em alguns casos, a perda do animal acometido. Na grande maioria dos casos, o órgão desloca-se para o lado esquerdo, caracterizando-se assim, o deslocamento de abomaso à esquerda (DAE), conquanto, pode deslocar-se também à direita (DAD). O diagnóstico consiste no sinergismo entre histórico e exame clínico, sendo que a percussão auscultatória de um “ping” metálico é bastante sugestivo da ocorrência da enfermidade. Não obstante, afirma-se como definitivo caso da paratopia apenas por intermédio da laparotomia exploratória. Existem métodos de tratamento clínico e poucos invasivos, conquanto, a terapia cirúrgica é a que apresenta melhores resultados. Esta revisão busca elencar os fatores responsáveis pela ocorrência da paratopia, a sintomatologia clínica observada, métodos de diagnóstico, tratamento e prevenção dessa anormalidade em bovinos.
