“…O estresse causado pelas pressões que o gado leiteiro sofre para alcançar altas produções, associado aos regimes de confinamento, onde o exercício é limitado, aumenta a possibilidade de ocorrer hipomotilidade ou atonia abomasal (Radostits et al 2007). Entretanto, algo comum em ambos os sistemas de manejo foi a oferta de moderadas a elevadas quantidades de grãos associado a dietas com, na maioria das vezes, fibras de má qualidade, sendo este um dos principais fatores associados à ocorrência do DA (Coppock et al 1972, Shaver 1997, Stengärde & Pearson 2002, Van Widen & Kuiper 2003.…”

“…Em 1961, Dirksen postulou que a desordem de motilidade abomasal (hipomotilidade ou atonia) ocorreria anterior à dilatação do órgão (Dirksen 1961). Esta hipótese vem sendo averiguada por diversos pesquisadores, e é relacionada, na maioria dos casos, à concentração elevada de carboidratos de fermentação rápida em relação à quantidade de fibra efetiva da dieta, principalmente no pós-parto (Coppock et al 1972, Shaver 1997, Cameron et al 1998, Stengärde & Pehrson 2002, Doll et al 2009.…”

ABSTRACT.-Câmara A.C.L., Afonso J.A.B., Costa N.A., Mendonça C.L., Souza M. The continuous genetic selection for high milk production in association with greater digestive capacity and corporal depth increases the susceptibility for abomasopathies including abomasal displacement. The present work aimed to accomplish a retrospective study on abomasal displacement in 36 cattle attended at Bovine Clinic, Garanhuns Campus, Federal Rural University of Pernambuco, through January 2000 to February 2009. Twenty seven cases of right abomasal displacement, six cases of left abomasal displacement and three of abomasal volvulus were diagnosed. Eleven moderate cases, without severe abdominal distention, appetite for roughage and metallic sound ("ping") reaching at the most the 8 th intercostal space were treated conservatively, and 20 severe cases with moderate to severe abdominal distention associated to systemic disturbances were treated surgically. Two cows were euthanized due to diffuse peritonitis or severe alterations in the abomasal serosa totalizing 18 animals submitted to the surgical treatment. Two animals were slaughtered and three cows arrived prostrated and died without receiving any treatment. Risk factor analysis identified rainy season as statistically significant. The greater number of abomasal displacement was in crossbred cows with 24 cases (66.6%), followed by Holstein and Gir cattle with 11 (30.5%) and one (2.9%) cases, respectively. Food composition varied greatly and characterized by excess of carbohydrates and in most cases low quality fibers. Most frequent clinical signs were apathy, dehydration, light to severe ruminal bloat with reduced or absent motility, splashing sound during right flank ballottement, ping and a distended visceralike structure in the side of the displacement; liquid, blackish and fetid feces. Hematology reveals leukocytosis with neutrophilia and hyperfibrinogenemia in most cases. Ruminal fluid analysis showed compromised flora and fauna dynamics and increased chloride ion concentration in 93.9% of the cases achieving the media index of 47.66 mEq/L. Clinical and surgical recovery rate achieved 100% and 72.2%, respectively. Those methods described are viable options for the treatment of light and severe displacements but the prevention remains the best choice.

“…Higher supplement levels may have resulted in greater dispersion of M throughout the rations, possibly suppressing intake relative to other studies. Feed intake by group-fed cattle is known to be higher than that by those fed individually (Coppock et al 1972;Phipps et al 1983). It is possible that the intake-suppressing effects of monensin would be amplified by the more passive eating patterns of individually fed cattle.…”

. 2001. Effect of salinomycin or monensin on performance and feeding behavior of cattle fed wheat-or barley-based diets. Can. J. Anim. Sci. 81: 253-261. Feeding behavior and growth performance of cattle fed diets containing monensin or salinomycin were assessed in two trials. In trial 1, 36 Hereford × Angus steers (267.7 ± 4.3 kg) were individually fed (n = 12) wheat-based transition and finishing diets containing no ionophore (control, C), 26 mg monensin (M) or 13 mg salinomycin (S) per kg of dietary dry matter (DM). Cattle fed M consumed less than those fed C or S, and their intake was more stable during the transition to the finishing diet. Overall, steers fed M exhibited lower dry matter intake (DMI) (8.0 vs. 9.2 and 9.2 kg d -1 ) and rates of gain (1.21 vs. 1.62 and 1.56 kg d -1 ) than those fed C or S. Cattle fed S required fewer days (93.3) to reach the targeted finish (5 mm backfat) than those fed C or M (105.8 d). Monensin reduced slaughter weight and carcass weights, relative to controls (414.3 vs. 480.5 kg, and 231.2 vs. 245.8 kg, respectively). In trial 2, M (25 ppm) or S (13 ppm) were included in barley-based diets for 72 yearling steers placed in four pens equipped with radio frequency identification systems. Individual bunk attendance patterns were monitored during transition to a finishing diet, during 11 d of limit feeding the finishing diet twice daily (LF2/d), 13 d of limit feeding once daily (LF1/d), and 21 d of feeding once daily to ad libitum intake (AL1/d). Ionophore type did not affect (P > 0.10) DMI, rate of gain or efficiency of feed conversion. Bunk visits were more frequent (P < 0.05) with M than with S during transition and limit-feeding. With M, total daily attendance (TDA) at the bunk during LF1/d and AL1/d, was higher (P < 0.05) than with S, and variability in TDA was lower (P < 0.05) during LF1/d. In the present study, there was no performance advantage in providing S or M in wheat-based finishing diets. Monensin moderated feeding intensity, but this effect may have been strong enough to suppress intake and even reduce gain on the wheat-based diet. . Lors du deuxième essai, on a ajouté du monensin (25 ppm) ou de la salinomycine (13 ppm) à la ration à base d'orge de 72 bouvillons d'un an répartis dans quatre enclos dotés d'un système d'identification radio. On a surveillé les habitudes de chaque animal pendant la période où les mangeoires étaient remplies de la ration de transition puis de finition selon trois régimes : quantité restreinte de la ration de finition servie deux fois par jour pendant 11 jours (RF2/j), quantité restreinte de la ration de finition servie une fois par jour pendant 13 jours (RF1/j) et ration servie à satiété une fois par jour pendant 21 jours (AS1/j). Le type d'ionophore n'affecte pas le CMS (P > 0,10), le gain de poids ni la valorisation des aliments. Les animaux se rendent moins souvent à la mangeoire (P < 0,05) quand les aliments renferment du monensin plutôt que de la salinomycine durant la période de transition et quand il y a restriction de la quan...

“…Approximately 24% of the specialized dairy cows herds have at least one case of LDA in a period of three years (Coppock et al, 1972). Detilleux et al (1997) reported that economic losses related to this disease are due to the reduction in milk production during the convalescence period, and the high cost of the treatment.…”

-The objective of this work was to evaluate hematological, biochemical and ruminant parameters for diagnosis and treatment of the left displaced abomasum (LDA) in dairy cows, in the Plateau Region of Rio Grande do Sul, Brazil. Ruminant fluid, blood and urine samples were collected from 20 cows suffering LDA and from 20 healthy cows (control). The cows with LDA showed lower values of daily milk production, body weight and corporal condition score. The use of pH reagent strips showed to be functional in the field, when compared to a digital pH meter. Ruminant dynamics was damaged in cows affected by LDA, as it was evidenced by the higher reduction time of methylene blue. Serum values of lactate, beta-hydroxybutyrate, urea, albumin, free fatty acids and cholesterol shows to be auxiliary tools in the LDA characterization.Index terms: abomasopexy, dairy production, ketosis, nonesterified fatty acids. Indicadores hematológicos, bioquímicos e ruminais no diagnóstico do deslocamento de abomaso à esquerda em vacas leiteiras do Sul do BrasilResumo -O objetivo deste trabalho foi avaliar indicadores hematológicos, bioquímicos e ruminais no diagnóstico e tratamento do deslocamento de abomaso à esquerda (DAE) em vacas leiteiras, na Região do Planalto do Rio Grande do Sul, Brasil. Foram coletadas amostras de líquido ruminal, sangue e urina de 40 animais, dos quais 20 vacas com DAE e 20 vacas clinicamente sadias utilizadas como grupo controle. Os animais com DAE, quando comparados ao grupo controle, apresentaram diminuição da produção de leite diária, do peso corporal e do escore condição corporal. A utilização de fitas reagentes para medição do pH ruminal demonstrou-se eficaz em campo, em comparação ao potenciômetro digital. A dinâmica ruminal apresentou-se prejudicada nos animais com DAE, o que foi evidenciado pelos valores aumentados do tempo de redução de azul de metileno. Os valores séricos de lactato, beta-hidroxibutirato, uréia, albumina, ácidos graxos livres e colesterol apresentam-se como ferramentas auxiliares na caracterização da doença.Termos para indexação: abomasopexia, produção de leite, ácidos graxos não-esterificados, cetose.
