WikiNews 1st December 2008 - WikiVet receives funding from the British Society of Toxicological Pathologists BSTP http://www.bstp.org.uk/ The BSTP has just agreed to provide sponsorship to support the WikiVet project in 2009. This funding will be used to cover wiki server hosting costs at the University of London Computer Centre. 23rd October 2008 - WikiDrugs Ready for Population All the WikiClinical stub pages are now in place. Please feel free to start populating these pages with lots of clinical knowledge. If you are having trouble editing pages please refer back to our help pages. 9th October 2008 - The Wiki is Launched Attendees of the WikiVet Launch The WikiVet project was officially launched at MEDEV, Newcastle University. People from varying aspects of the Veterinary, Educational, Pharmaceutical and Medical professions attended the conference. Five people also attended the virtual conference, which made for an exciting yet interactive session. We feel that the launch was a great success and look forward to watching WikiVet grow. Article of the Week - Rumination Diagram of ruminating contractions - Copyright RVC 2008 Rumination is the process of digestion in the ruminant. It involves three simplified processes. the first is regurgitation which increases the surface area of food particles for digestion through further mechanical breakdown. The second is re-mastication and the third reinsalivation. Reinsalivation increases the volume of saliva produced whilst chewing and allows minerals to be recycled. Process Reflex initiated by mechanical stimlation of the receptors in the mucosa of the reticulum, ruminoreticular fold and cardiac area of the rumen Frequency of contractions depends on the animal's activity E.g. Cattle fed on hay or straw have the most frequent contractions at 79-100 per hour during feeding, 55-76 per hour during rumination E.g. Cattle that are resting (not feeding or ruminating) only have contractions 47-80 per hour Discrete reticular contraction preceedes biphasic ruminal contraction (see ruminoreticular contractions) Rumination depends upon the coordination of the stomach movements with the thoracic wall and throat Associated with inspiration against a closed glottis creating a negative pressure in the thorax allowing ingesta to be drawn into the oesophagus Ingesta carried orally via an antiperistaltic wave Controlled by rumination centres in the hypothalamus Fibre increases stomach motility Increase in volatile fatty acids decrease stomach motility Click here to read more
