Term
What is the WHITE LINE in the hoof?
Definition
Which structure forms the FIBROUS JOINT BETWEEN THE HOOF WALL AND THE SOLE?
Term
What is WHITE LINE DISEASE?
Definition
Which disease shows clinically as haemorrhage into or separation of the white line on the apical or abaxial border of the sole, most commonly at the heel-sole junction, resulting in an infection?
Term
Give some causes of LAMINITIS
Definition
Which secondary disease process can result from SUB-ACUTE RUMINAL ACIDOSIS?
Term
In dairy cattle what is the main cause of LAMINITIS, with the condition being exacerbated by secondary issues, such as concrete floors and long periods of time standing on hard surfaces?
Definition
RUMINAL ACIDOSIS is the primary cause of which disease process in dairy cattle?

Term
What are some of the risk factors for the development of INFECTIOUS LAMENESS?
Definition
WET, MUDDY CONDITIONS, HIGHT PREVELANCE OF DISEASE CAUSING PATHOGENS IN THE AREA, CROWDED AREAS WITH MANY CATTLE AND POOP are risk factors for which disease?
Term
What are some management issues associated with LAMENESS?
Definition
STEEP SLOPES
SHARP TURNS IN LANEWAYS OR NARROW GATES
POOR MAINTAINENCE OF THE LANEWAYS
LARGE HERD SIZE (LONG WAITING TIMES FOR MILKING)

Definition
3% of body weight
Term
Name the 4 chambers of the ruminant's "stomach"
Definition
Rumen, reticulum, omasum and abomasum
Term
Which part of the ruminant fore stomach takes up the majority of the LEFT SIDE of the ABDOMINAL CAVITY?
Definition
THE RETICULO-RUMEN sits on which side of the abdominal cavity?
Term
What is the capacity of the RETICULO-RUMEN?
Definition
Which section of the fore-stomach has a capacity of 100-150 L?

Which section of the fore-stomach has a volume of 7-18L?
Term
What is the capacity of the ABOMASUM?
Definition
Which section of the ruminant GIT can hold 10-20L?
Term
Name the main landmarks of the RUMEN in a clockwise direction tarting at the oesophagus
Definition
Oesophagus, dorsal sac, dorsocaudal blind sac, caudal pillar, ventrocaudal blind sac, ventral sac, cranial pillar, atrium, ruminoreticular fold, reticulum, reticulo-omasal orifice, reticular groove, oesophagus.
What does this list describe and does it run clockwise or counter clockwise?
Term
Which is the LARGEST SAC OF THE RUMEN?
Definition
Is the DORSAL SAC larger or smaller than the ventral sac?
Term
In which area of the GIT does HARDWARE DISEASE (or bovine traumatic reticuloperitonitis)occur?
Definition
Ingested foreign material (nails, wire etc.) may fall into the RETICULUM and cause what disease?
Term
What particle size is able to pass through the reticulo-omasal orifice?
Definition
2-4 mm
Term
Which section of the GIT is ACID SECRETING AND THE "TRUE" STOMACH WITH A FUNDIC AND PYLORIC REGION?
Definition
What is the ABOMASUM?
Term
Explain how a oesophageal blockage could lead to rUMINAL ACIDOSIS
Definition
What disease process could be created by preventing saliva from reaching the rumen. Remembering that saliva is high in bicarbonate.
Term
SARA is characterised by a rumen pH of 5.2-5.6, what does SARA stand for?
Definition
What is the characteristic feature of SUBACUTE RUMINAL ACIDOSIS?
Term
At what pH does RUMINAL STASIS occur?
Definition
What happens to the rumen at a pH of AROUND 5
Term
What are the clinical signs of CLINCAL ACUTE MASTITIS?
Definition
Which disease process is associated with the following clinical signs?
CATTLE OFF FEED, DROP IN MILK PRODUCTION, DEHYDRATION, TACHYCARDIA (90-120BPM), TACHYPNEA (50-80BPM), RUMEN STASIS, DECREASED TEMPERATURE, DIARRHOEA, WEAK, RECUMBENT, METABOLIC ACIDOSIS
Term
What are some of the aims of ruminal acidosis Tx?
Definition
The aims of treatment include, corrcting rumen pH, correcting hydration status, discourage future lactic acid production, minimise the effect of endotoxins, restart the rumen motility and reduce the risk or liver abscessation.
Term
How can you correct fluid balance in large animals?
Definition
There are 2 main ways of giving fluids, in small animals we go straight to IV, though this is not easy to do in large animals. If IV fluids were to be given, a hypertonic solution followed by Hartmanns or lactated Ringers solution.

A more cost effective method is to use an oral drench, mix a large volume (around 20L) with 45g NaCl and 60g of bicarb / 5L of water.
