“…However, the reuse of cellulose fibers in manure from animal husbandry, particularly the most prevalent cow dung, has seldomly been researched. The cows, as ruminants, eat plant-based food, which is taken into the cows’ four-chambered stomach, where it is digested and broken down into smaller pieces before the excretion of dung [ 20 ]. Within these chambers, the food is subjected to mechanized processing while different digestive enzymes and microorganisms break down the plant fibers, notably hemicellulose and pectin.…”

The widespread use of petroleum-based products has led to increasing environmental and ecological problems, while the extraction and application of various natural cellulose fibers have received increasing attention. This research focuses on the extraction of cellulose fibers from cow dung using different treatments: hot water, hydrogen peroxide (H2O2), sodium hydroxide (NaOH) and potassium hydroxide (KOH) boilings, as well as a selection of the best quality cow dung fibers for papermaking with quality control. The study’s objective is to find a sustainable method to extract as much material as possible from renewable biomass feedstock. The results show that the best extraction rate is obtained by KOH boiling with 42% cellulose fibers extracted. Corresponding handmade paper has a burst index of 2.48 KPam2/g, a tear index of 4.83 mNm2/g and a tensile index of 26.72 Nm/g. This project expands the sources of natural cellulose fibers to an eco-friendly and sustainable one and opens up new applications for cow dung.

“…The abomasum constitutes the largest gastric portion of newborn calves, as they need to use nutrients from their exclusively milk-based diet, not requiring as much of the rumen-reticulum and omasum, which are important for the fermentation of structural carbohydrates in roughages [ 1 , 16 ]. In the laparoscopy of the fetuses, the abomasum was physically developed and located in the right half of the abdominal cavity, on the floor of the abdomen, where it was possible to explore and manipulate the organ and identify it for performing the laparoscopic cannulation technique.…”

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.

“…Type-3 is a perforated ulcer accompanied by localised peritonitis [3], U4 is a perforated ulcer characterised by generalised peritonitis [4] and U5 is an ulcer that has perforated into the omental bursa causing omental bursitis [5]. Ultrasonographic examination of the abomasum has been described in cows [6] as well as in calves [7]. The abomasum can be visualised about 10 cm caudal to the xyphoid in cows and it occupies more space on the right side of the median than the left.…”

Background: Ultrasonographic documentation of perforated abomasal ulcer has not been published till now. This report describes the clinical, ultrasonographic and postmortem findings in a Jersey cow with type-3 abomasal ulcer and left displacement of the abomasum (LDA). Case report: The main clinical findings were abnormal demeanour, rumen atony and tympany, positive foreign body tests, positive auscultation and simultaneous ballottement on the left side, abdominal guarding and loss of negative pressure in the abdominal cavity. The tentative diagnosis was peritonitis and LDA. Abdominal ultrasonography produced images typical of LDA, and in one location between the abdominal wall and abomasum there was a layer of fibrin, a fibrin clot, a break in the abomasal contour, suggestive of a perforated ulcer, and partial obstruction of this gap with fibrin. The diagnosis of perforated abomasal ulcer with subsequent peritonitis was confirmed during postmortem examination. Conclusions: The examination of this case shows that under certain circumstances, ultrasonographic imaging of a perforated abomasal ulcer in a cow is possible. Antemortem diagnosis of type-3 abomasal ulcer is preferable to relying on exploratory laparotomy and/or post-mortem examination.
