Optimising water medication

Posted by:

By Dr Annie Labuscagne, CSVet

Water medication is a viable option to medicate a group of pigs. It gives flexibility to the producer, especially if the crisis is now and the feed tank was filled late yesterday. Another advantage is that sick pigs tend to drink water after they have stopped eating; your chances of medicating those that really need it is therefore better. Continue Reading →

Quick guide to Clostridium perfringens Type C

Posted by:

By Dr Andrew Tucker, CS Vet

Clostridium perfringens Type C is a bacteria that colonises the large intestine of newly born piglets. It can colonise the jejunum and ileum within 12 to 24 hours of birth. Here it then causes damage to the cells lining the intestinal wall. It causes damage by releasing toxins as well as penetrating these cells. Toxins can also be absorbed into the rest of the piglet’s body. Continue Reading →

Quick guide to Glasser’s disease

Dr Andrew Tucker – Charles Street Veterinary Consultancy

Glasser’s disease is caused by the infection of pigs with the bacteria Haemophilus parasuis. The bacteria is spread primarily by contact and the aerosol route and has an incubation period of as short as 12 hours. Outbreaks usually occur in piglets 3-6 weeks of age but any age pig can be affected. The bacteria starts by colonising the tracheal mucus and then progresses into causing pneumonia. As the infection progresses further you get a build up of fluid in the thorax and abdomen. In the chronic form of the disease this fluid organises to leave peritonitis and pleuritis which often persists until slaughter. Continue Reading →

Eperythrozoonosis is caused by Mycoplasma haemosuis, formerly known as Eperythrozoon suis.  M. Haemosuis locates itself on the membrane of the red blood cell. This causes the red blood cell to become quite fragile and leads to its break down. Continue Reading →

Quick guide to Ascoiosis

Dr Andrew Tucker, CS Vet

Ascariosis is caused by the roundworm Ascaris suum. This worm has a direct life cycle in pigs starting with ingestion of the egg. The larvae hatch and enter the mucosa in the pig’s caecum. Six hours after being ingested these larvae have already migrated to the pig’s liver where they moult and then move on to the lungs. Here they moult again and are then coughed up and swallowed by the pig. They now move down to the small intestine where they mature and will start to produce eggs which then restart the life cycle.
