“…The correlation between ORP and MBRT in the present study was high (r = 0.696) indicating the good relationship between these tests. Thus, as might be expected, oligofructose ruminal acidosis causes serious changes in the ruminal environment, similar to what happens in acidosis with other more traditional soluble carbohydrates [32].…”

The objective of this study was to characterize oligofructose-induced acute rumen lactic acidosis and its consequences in zebu cattle. We used 29 Nellore heifers which were submitted to experimental induction of laminitis by oligofructose excess. During the induction period, the animals underwent clinical examination, including laminitis diagnosis (hoof pressure testing and locomotion score) and blood and ruminal fluid sampling every six hours (over the initial 24 h) and every 12 h (up to 72 h), after the highest dose. Almost half of the animals (48.1%) required treatment with bicarbonate and saline to correct metabolic acidosis and dehydration. Due to this treatment, the animals were analyzed in treated (n = 13) and non-treated (n = 14) groups. The induction model promoted marked reduction in rumen pH, rumen anaerobiosis, carbon dioxide pressure, and increase in rumen lactate, blood osmolarity, and cortisol concentration. The animals treated had lower values of rumen pH and marked dehydration, evidenced by the increase in globular volume and serum urea. The clinical condition caused by excess oligofructose is severe, with the differential of the appearance of ephemeral fever and respiratory compensation against systemic acidosis, in addition to the frequent appearance of laminitis.

“…A alimentação de ruminantes é composta essencialmente por componentes fibrosos, que agem fisiologicamente regulando o pH ruminal e influenciando na dinâmica de crescimento dos microrganismos [5]. A acidose ruminal é caracterizada pela diminuição do pH, resultando em impactos significativos na atividade microbiana e função do rúmen, bem como na produtividade e saúde animal [4,8].…”

Ruminal Acidosis Caused by Excessive Ingestion of Mango Fruit (Mangifera indica) in Cow

Background: Digestive disturbances in ruminants are associated with forage shortages during periods of dry weather. Foods available at this time are generally of poor quality and low digestibility, which makes it necessary to pursue alternative food sources where available. Grain-heavy diets; concentrated rations rich in rapidly fermenting carbohydrates; and whey, tubers and fruits high in starch and glucose, contribute to ruminal acidosis. Here we report a case of ruminal acidosis due to excessive ingestion of the mango fruit (Mangifera indica), "manguita" cultivate, by an adult bovine.Case: In the municipality of Boa Vista, Roraima, during December, a Dutch female bovine adult, weighing approximately 600 kg, was observed showing signs of apathy for two days with diarrhea. The animal had a rumenostomy with flexible cannula in the left paralumbar fossa and was in the final third of gestation. During clinical examination, the animal was in season, and an increase in the volume of the left dorsal region and changes in physiological variables were observed (lightly pale mucosa, capillary filling time of 4 s, heart rate [HR] of 82 beats per min; respiratory rate (f) of 30 moments per min; absence of ruminal movements and rectal temperature [RT] of 39.5°C). Upon removal of the cannula lid, a considerable amount of liquid and a large quantity of mango (Mangifera indica), "manguita" cultivate, were observed. Blood sample and ruminal fluid were collected and ruminal contents weighing approximately 40 kg were evacuated. Physical-chemical analysis of the ruminal liquid (pH = 4.0, brown color, aqueous consistency and characteristic fruit odor) resulted in a diagnosis of ruminal acidosis. Treatment included administration of fluid therapy (Lactate Ringer; 2 mL/kg/h), hepatoprotector (1 mL/20 kg), antimicrobial (Ampicillin Sodium; 10 mg/kg/IV and Sulfadoxine; 30 mg/kg/IV) and non-steroidal anti-inflammatory (Meloxicam; 0.5 mg/kg/IV) drugs, associated with evacuation of ruminal contents, and administration of grass and transfaunation, for three days. Following treatment, the physiological variables and physical-chemical characteristics of the ruminal liquid returned to normal limits (pH = 6.0, greenish brown coloration, aqueous consistency and aromatic normal ruminal liquid odor). By 30 days of initial care, the animal was active and had given birth, with no abnormal changes in physiological variables and physical-chemical characteristics of the ruminal fluid.Discussion: A decrease in food supplies during the dry season forces animals to seek alternative sources of food to meet their needs, as observed in this case study. Intake of a large amount of mango was the cause of ruminal acidosis due to an overabundance of simple sugars. The measures established for the clinical evaluation, diagnostic methods used, collection of blood sample and rumen fluid, and the adopted therapy, administration of fluid therapy, antimicrobial and non-steroidal anti-inflammatory, associated with evacuation of the ruminal content, transfaunation, administered directly to the rumen, were essential to directing the diagnosis and obtaining a fast recovery time for the female bovine. Therefore, it can be concluded the excessive intake of fruit was the primary cause of rumen acidosis, and efficient case management led to observed clinical improvements in the physical-chemical characteristics of the ruminal liquid, with no recurrence of previous clinical signs.

“…O rúmen depende de materiais fibrosos que agem fisiologicamente regulando seu pH e influenciando na dinâmica do crescimento da população bacteriana. Desequilíbrios no pH do suco ruminal são produzidos com a ingestão de altas quantidades de carboidratos altamente fermentáveis sem a prévia adaptação, o que pode levar à ocorrência da acidose ruminal (Oliveira et al, 2016).…”

 RESUMOObjetivou-se avaliar clinicamente os efeitos da administração intrarruminal de duas quantidades distintas de manga em ovinos. Foram utilizados sete ovinos machos, hígidos, que não receberam carboidratos não fibrosos por, pelo menos, seis meses previamente ao período experimental, quando se avaliou pH ruminal, total de protozoários no suco de rúmen, pH urinário, pH sanguíneo estimado e parâmetros vitais nos tempos zero, 12, 16, 20 e 24 após a administração da manga. Os sete ovinos foram distribuídos aleatoriamente em dois grupos e receberam 0,625% ou 1,875% da MS de manga/kg/PV (M1 e M2, respectivamente), distribuídos em delineamento cross-over, com uma parcela perdida, e 30 dias de washout. Os ovinos M2 apresentaram valores médios para pH ruminal significativamente inferiores a M1 a partir do tempo T12 (5,1 e 6,9, respectivamente), o que indica ocorrência de acidose ruminal. Os animais tratados com M1 não apresentaram alterações sistêmicas, ao passo que os ovinos tratados com M2 apresentaram acidose metabólica leve, detectada por meio do pH urinário ácido (4,8). A ingestão apenas de manga in natura na quantidade de 1,875% da MS de manga/kg/PV mostrou-se capaz de provocar acidose ruminal em ovinos, levando-os a: ligeira depressão, aumento da frequência cardíaca, diminuição dos movimentos ruminais e diarreia em alguns casos.Palavras-chave: acidose, rúmen, manga, pequenos ruminantes ABSTRACT The aim of this study is to clinically evaluate the effects of intra ruminal administration of two different
