“…The wide application of rumen cannulation is based on the assumption that it does not have adverse effects on rumen digestive, physiological, and metabolic functions. However, the laparotomy incision is frequently larger than the diameter of the cannula, and the muscle and skin support around the cannula can be compromised, leading to leakage of fermentation gases and rumen content (Grovum, 1989;McSweeney, 1989;Rafee et al, 2015). Leakage of fermentation gases from the rumen can be associated with increases in concentrations of gaseous nitrogen (gN 2 ) and oxygen (gO 2 ), and reductions in carbon dioxide (gCO 2 ), methane (gCH 4 ), and hydrogen (gH 2 ) concentrations in the headspace of the rumen.…”

Rumen cannulation is a widely employed technique in ruminant nutrition research. However, the gap between skin and rumen cannula can cause leakage of fermentation gases and influx of atmospheric air, which may adversely affect the anaerobic environment in the rumen. The present study was designed to investigate the effects of rumen cannulation on headspace gases, dissolved gases, fermentation end products, and methanogen community in the rumen of dairy cows. Eight Holstein cows were used in the experiment. Four cows were surgically fitted with rumen cannulas, whereas the other 4 intact cows were used as control. Rumen cannulation decreased gaseous hydrogen and methane concentrations, dissolved carbon dioxide concentration, and relative abundances of Methanosphaera, and increased the saturation factor of dissolved hydrogen and dissolved methane, dissolved methane concentration, volatile fatty acid concentration, 16S ribosomal RNA gene copies of methanogens, and Simpson index of methanogen community. In summary, rumen cannulation causes a reduction in headspace gaseous hydrogen and gaseous methane, which may not decrease dissolved gas concentrations due to an increase in saturation factors. Furthermore, rumen cannulation alters methanogen community with increased methanogen population and decreased relative abundances of Methanosphaera.

“…The laparotomy for access, exteriorization and cannulation of the abomasum requires a surgical incision in the right flank and three-layer suture, and is therefore a more invasive and traumatic method when compared to minimally invasive procedures [12,13]. Digestive organ cannulation using a minimally invasive technique can provide better patient recovery with fewer postoperative complications, improving animal welfare [13][14][15].…”

Background Due to the complexity of ruminant digestion, cannulation of organs of the digestive tract has been carried out in order to advance the understanding of digestive physiology, nutrient degradability, gastrointestinal diseases and biotechnological research. The abomasal cannulation is interesting for nutritional studies, especially in suckling calves, to obtain fluid and abomasal content, evaluation of abomasal flow and function, and infusion of nutrients and drugs when it is intended to reach high concentrations in the organ. Conventionally, access and cannulation of digestive organs of ruminants has been performed by laparotomy, a method often criticized and classified as cruel by some sectors related to ethics and animal welfare. The aim of this present study is to describe and standardize a minimally invasive by laparoscopy assisted abomasal cannulation in bovine fetuses (cadavers), which had been previously slaughtered by accident and would be discarded in local slaughterhouses. Results The abomasal cannulation technique was feasible, simple and did not present major difficulties. The surgical time for cannulation of the abomasum, from the insertion of the trocars to the completion of the technique with fixation of the organ to the abdominal wall, ranged from 9 to 27 min, with an average of 15.5 ± 6.62 min. Conclusions The Laproscopic assisted abomasal cannulation in bovine fetuses was feasible and safe with minimal tissue injury to the abdominal wall and with short surgical time. More studies in the clinical routine related to minimally invasive abomasal content collection, abomasopexy and abomasotomy are required in order to demonstrate its impact and importance in bovine clinic.

“…Rumino-cutaneous fistulation is an anomalous interaction between the rumen and skin that results in major economic losses in ruminants (Omid and Mozaffari, 2014;and Singh et al, 2016). Outflow of leaked high amounts of ruminal juice from rumino-cutaneous fistulation in buffaloes causes skin lesions, dehydration, malnutrition, unpleasant odor, myiasis and septic peritonitis (Rafee et al, 2015). Moreover, the increase in the treatment costs and potential fatalities due to resultant septic peritonitis (Sileshi et al, 2013).…”

“…The closure rates of rumino-cutaneous fistulation vary substantially depending on the degree of fistulation (Omid and Mozaffari, 2014). In addition, the correct description of rumino-cutaneous fistula anatomy is important for further planning of operative repair (Rafee et al, 2015). Therefore, establishing and maintaining successful fistula recovery involves rapid surgical intervention with continuing reassessment of wound closure over time.…”

One of the most prevalent postoperative complications following rumenotomy is ruminocutaneous fistulation, which can cause significant economic issue in ruminant. The aim of this study was to determine the clinical, hematobiochemical, and ultrasonographic variations in rumino-cutaneous fistulation before and after surgical correction in buffaloes. Five buffaloes with rumino-cutaneous fistulation and five clinically healthy buffaloes were evaluated in this study. Buffaloes with rumino-cutaneous fistulation exhibited reduced appetite, decreased rumen motility, scanty feces, and significant alterations in hematobiochemical parameters compared with clinically healthy control buffaloes. Ultrasonographically, buffaloes with rumino-cutaneous fistulation displayed a significantly lower rate of rumen contractions and a substantial increase in the thickness of ruminal and abdominal walls. Significant postoperative improvement in clinical, hematobiochemical and ultrasonographic parameters in affected buffaloes was noted. In conclusion, rumino-cutaneous fistula is a common surgical complication of rumenotomy and rumen trocarization in buffaloes. Surgical interference by excision of fistulous tract is satisfied for treatment. Ultrasonographic, clinical and hematobiochemical examinations are essential for the proper assessment of rumino-cutaneous fistulation before and after surgical correction in buffaloes.
