Pre-Weaning Diarrhea
A 2-day old piglets develop watery diarrhea but continues nursing. Histopathology reveals INTACT VILLI. What is the most likely pathogen
Enterotoxigenix E. coli (ETEC)
True or False: ASF (African Swine Fever) causes profuse diarrhea
False
What deficiency causes piglet anemia?
Iron
What does AIAO stand for?
All in All out?
This metric measures amount of feed consumed per pig per day.
Average Daily Feed Intake (ADFI)
This pathogen causes diarrhea in young piglets of 1-4 weeks. Also referred to as “milk scours”
Rotavirus Type A
Grow-finish pigs show fever, large volume of diarrhea, and some are acutely dead. Necropsy shows diffusely thickened small intestines.
Salmonellosis
What pathogen is responsible for “diamond” shaped skin lesions?
Erysipelas rhusiopathiae
How to control Rotavirus?
Sanitation, All-in-all-out(AIAO), don’t mix litters.
Vaccines are inconsistent
This metric measures average weight gained per pig each day
Average Daily Gain (ADG)
1-7 day old piglets, bloody diarrhea, sudden death. Necropsy shows profuse hemorrhage of the jejunum.
Clostridium perfinges type C Enteritis
This pathogen is commonly seen in grower pigs, producing mucohemorrhagic diarrhea
Brachyospira hyodysenteriae (Swine Dysentery)
Mortality Rate for pseudorabies?
95-100%
How to control Clostridium perfinges type c?
Vaccinate sows before farrowing, feed Bacitracin Methylene Disalicylate (BMD) to sows pre and post farrowing, sanitation, antitoxins
What is a better FCR? 0.67 or 6.7
0.67
TGE (Transmissible Gastroenteritis) is what type of diarrhea?
This pathogen is responsible for hyperplasia of the crypt cells in the ileum. Also known as garden hose gut
Lawsonia intracellularis (Ileitis)
This genetic mutation in heavy muscle pigs make some of them very prone to stress, as they turn hyperthermic and rigid, followed by possible death. During inspection, it is classified as PSE (pale, soft, exudative) pork. What is the gene?
RYR1
This parasite migrates through liver and lungs, causing ”Milk Spot” scars on the liver. How to treat?
You don’t have to tbh.
But you can use FBZ, continuously fed pyrantel, or ivermectin.
This is one of the key sow-farm production indicators. It measures number of piglets weaned by a single sow over a 12 month period
