-
1. no problem
2. mild clinical dz- low grade peritonitis
3. localized peritonitis
4. puncture, abcess (hepatic, around the vagal nerve), trama to vagal nerve, - What is transfernation?
- get supernatant form teh ruminal contents of a healthly cow and place it inot a cow that has poor microflora to replace healthy microbes
- What borders the paralumbar fossa?
-
dorsally- transversus process
cranial- 13th rib
caudal- tuber coxae - What are some agents that can break up frothy bloat?
- mineral oil and therabloat
- In cases of pericarditis, what treatment option is preformed on valuable animals?
- chestwall resections
- What are clinical signs seen with acute TRP?
- sharp decrease in milk production, off feeding, standing with arched back, stand abducted, no rumination, positive responce to grunt test (pain)
- What side is the kidney palpable?
- the left kidney is more caudal than the right
- How can TRP be prevented?
- administer magnets, build elevated platform- pulls pressure off the reticulum b/c abdominal viscera is up
- What clinical pathology can be seen in animals with TRP?
- neutrophilia with a left shift, increase in total protein, hyperfibrinogenemia
- What is done to adhesions once they are found between the liver and rumen?
- nothing b/c you run the chance of rupturing the wall on the rumen
- What antibiotic drug is not recommended for the use in cows in the milk production?
- tetracycline- 30 days before the cow can get back into the line
- What are the two types of roughage?
- haylage and silage
- What are is type I vagal indigestion?
- failure of eructation/free gas bloat
- What is type II vagal indigestion?
- failure of omasal transport
- What is type III vagal indigestion?
- abomasal impaction
- What is type IV vagal indigestion?
- incomplete pyloric stenosis
- What are three main causes of disorders of the rumen and forestomach?
- inflammatory, dietary, and mechanical
- What is the cause of vagal indigestion
- damaged or inflammed vagal nerve on or around the abdomen, pharynx, larynx, esophagus, and thoracic cavity
- What are four ways to medically manage Type II vagal indigestion?
- laxatives (rumenotorics), Ca supplementation, better quality feed, decrease exercise
- Where is the rumen?
- occupies most of the left side extends from the 7th/8th rib to the pelvis
- Where is the reticulum?
- lies against the diaphragm on the left opposite the sixth to eighth ribs
- Where is the omasum?
- right of the midline; ventral aspect of ribs seven to eleven
- Where is abomasum?
- right of the midline,extends from the xiphoid area to the 9th/10th intercostal space
- What is the innervation of the rumen?
- the dorsal vagal trunk
- What innervates the reticulum?
- caudal aspect is innervated by the dorsal vagal trunk, majority innervated by the ventral
- What innervates the abomasum?
- the viscera is innervated by the dorsal vagal trunk and the rest is by the ventral.
- What does the ventral vagal trunk innervate?
- reticulum, parital reticulo-omasal jxn, omasum, and abomasum
- What does the dorsal vagal trunk innervate?
- rumen, caudal aspect of the reticulum, viscera of the abomasum, omasum
- What is the sympathetic innervation of the GI in bovine?
- splanchnic nerve
- What is the major site of microbial fermentation?
- rumen
- Where does most of digestion take place in the bovine GI?
- in the abomasum and the proximal duodenum
- Where are the common sites of "choke" in the bovine?
-
1. thoracic inlet
2. base of the heart
3. pharngo-esophageal jxn
4. cranial to the base of the heat - What differentials should be considered when dealing with "choke"?
- rabies, tetanus, botulism, plant toxicity (milkweed, sneezeweed, larkspur), trama, BVD, stomatitis, MCF, abscess, wooden toungue (actinomyces), lymphosarcoma, aspiration pneumonia
- What post surgical complications may occur after the treatment of choke?
- dehiscence, laryngeal hemiplagia, surgical complications: development of strictures, and diverticulum
