“…Garret et al (1997) reported a prevalence of SARA in 19% of early lactating cows and 26% in mid lactation cows and more than 40 per cent of the total number of cows were found to have SARA. Similarly high prevalence (32.5-37.7%) of SARA was reported by Attia (2016).…”

Background: Subacute ruminal acidosis (SARA) is one of the most important metabolic disease of dairy cattle which decrease milk production, dry matter intake, productivity and increase culling rate and even cause death.Methods: In this study the epidemiological status of SARA namely age, breed, stage of lactation, lactation number, general health condition, body condition score, daily milk production, milk fat content and biochemical alteration were investigated.Result: Out of 100 cows examined 20 were found to be positive for SARA and the mean age of dairy cows suffering from SARA was found to be 6.53 ±0.68 years. The prevalence of SARA was 70 and 30 per cent in Jersey and HF breed of cows respectively and was high in mid lactation and the lactation number ranged from 2 to 6. 65 per cent. SARA affected cows were in poor body condition score, milk production and milk fat content was significantly low (P≤ 0.05). The mean GGT (Gamma Glutamyl Transferase) and AST (Asparate aminotransferase) values were significantly increased in SARA affected dairy cows. SARA seems to be a common problem in dairy cattle and it has to be considered when dealing with herd level problems like low milk fat, low milk production, poor body condition and appropriate management measures should be implemented to prevent it.

“…that characterize these beef production systems. Some feedlot studies have proven the existence of an association between the occurrence of rumen pathologies and liver abscesses within the so-called ruminitis–liver abscess complex ( 1 , 12 ). In our study, the low prevalence of liver abscesses and the lack of any association between them and the rumen lesions suggest that a possible SARA condition affecting the inspected batches did not induce a severe inflammatory response with the translocation of bacteria and endotoxins across the ruminal epithelium.…”

“…With regard to digestive disorders, subacute rumen acidosis (SARA) is considered an important issue for both beef cattle health and farm economy ( 11 , 12 ). The development of SARA has been associated with the provision of high amounts of dietary non-structural carbohydrates ( 13 ) and/or of an insufficient amount of structured fiber ( 14 ).…”

Assessment of Rumen Mucosa, Lung, and Liver Lesions at Slaughter as Benchmarking Tool for the Improvement of Finishing Beef Cattle Health and Welfare

Abattoir post-mortem inspections offer a useful tool for animal disease surveillance. The present cross-sectional study aimed at assessing the prevalence of rumen mucosa, lung, and liver lesions in 153 randomly selected batches of finishing beef cattle through a post-mortem inspection at the abattoir. At least 15 animals per batch were inspected at slaughter by two veterinarians for a total of 2,161 animals (1,376 bulls; 785 heifers) coming from 80 Italian commercial farms. Rumens were inspected by recording as binary variables (presence/absence) signs of hyperkeratosis, ruminitis, ulcer, and star scars. Similarly, lungs were inspected for signs of pneumonia and livers for signs of lipidosis, abscesses, and/or adherence. Hyperkeratosis of the mucosa and signs of ruminitis were detected in 58 and 30% of the inspected rumens, respectively. Ruminal star scars were more prevalent in bulls than in heifers (18 vs. 11%; P < 0.05). Signs of severe pneumonia were observed in 10% of the lungs; abscess and/or adherence in 4% of the livers. Hyperkeratosis of rumen mucosa was correlated to signs of ruminitis, and signs of ruminitis were correlated to star scars. No correlations were found between hepatic lesions and any other rumen or lung disorders. The wide variability observed among batches for the prevalence of specific lesions suggested the development of a benchmarking system to provide feedback to the farm veterinarians, as these lesions can be reflective of a subclinical disease status not easy to be detected in the live animal. Quartiles of the batch prevalence of rumen, lung, and liver alterations (if ≥1%) were calculated as a benchmarking tool, and third quartile value was proposed as an alarm threshold for each lesion. The use of the benchmarking system could allow to allocate each inspected batch to a specific “health class.” Critical batches with a prevalence above the alarm threshold for a given lesion should be reported to veterinarians of the origin farms where actions should be taken in order to identify and lower the risk factors for that specific health issue. Knowledge of post-mortem inspection data along with the implementation of the proposed benchmarking system should help farm veterinarians to improve herd management from a health and welfare perspective.

“…However, this diet results in a decrease of ruminal pH by accumulating volatile fatty acids (VFAs) and lactic acid in the rumen (Nagaraja & Titgemeyer, 2007; Sato, 2016). High‐concentrate diets can also cause metabolic diseases such as hepatitis, abomasum displacement, and laminitis due to the release of ruminal lipopolysaccharide (LPS; Attia, 2016; Gozho et al., 2005) and changes in gut pH can alter bacterial communities (Kim et al., 2018; Nagata et al., 2018; Petri et al., 2013).

We used castrated and fistulated Japanese Black beef cattle (n = 9) to measure the pH and bacterial communities in the rumen liquid, rumen solid, and reticulum liquid during early, middle, and late fattening stages (10–14, 15–22, and 23–30 months of age, respectively). The pH was measured in the rumen and reticulum during the last 13 days of each fattening stage and was significantly lower in the rumen at the early and middle fattening stage and in the reticulum during the late stage. Sequencing analysis indicated similar bacterial compositions in the rumen and reticulum liquid fractions and stability of bacterial diversity in the rumen and reticulum liquid fractions and rumen solid fraction. By contrast, major operational taxonomic units (OTUs), such as Ruminococcus bromii strain ATCC 27255 (OTU1, OTU10, and OTU15), were differently correlated to the fermentation parameters among the rumen and reticulum liquid fractions. Therefore, the long‐term feeding of Japanese Black beef cattle with a high‐concentrate diet might reverse the trend of pH in the rumen and reticulum during the late fattening stage, and the bacterial communities adapted to changes in fermentation by preserving their diversity throughout fattening.
