At the abattoir
On farm
Medicines usage

Question 2

How is disease detected at the abattoir?

Answer 2

BPHS abattoir monitoring scheme give report 24 hours post abattoir submission with results of lungs, liver and other disease findings

Question 3

How is disease detected on the farm?

Answer 3

Mortalities/clinical cases
Days to slaughter
FCE

Question 4

What can cause pyaemia in pigs?

Answer 4

Tail biting as bacteria travels up lesions into the blood and bacteria are deposited in the capillary beds

Question 5

What bacteria causes gun shot wounds to lungs?

Answer 5

Actinobacillus pleuropneumoniae

Question 6

What are the financial impacts of disease?

Answer 6

Treatment costs
Vaccination costs
Vet costs for diagnostics
Mortality

Question 7

What costs of disease can be hard to quantify?

Answer 7

Suboptimal growth/ADG/days to slaughter
Food conversion efficiency
Secondary infection
Overhead costs

Question 8

What are some other impacts of disease other than financial?

Answer 8

Reduced FCE impact on environment
Supply of standardised product decreases
Public perception

Question 9

What are the characteristics of PRRS?

Answer 9

Multiple ages affected

Abortions, increased pre-weaning mortality, respiratory disease of growers

Question 10

How does PRRS cause losses?

Answer 10

Abortion or weak/still birth piglets decreasing pigs/sow/year
Impact on pig flow through the farm
Immunosuppressive, reduced markets to sell, boar stud shut down

Question 11

What does PED stand for?

Answer 11

Porcine epidemic diarrhoea

Question 12

What is PED?

Answer 12

Question 14

What does Mycoplasma hyopneumoniae cause?

Answer 14

Consolidation of cranial lung lobes with mild cough in uncomplicated cases
Attaches to cilia of mucociliary escalator

Question 15

What is the economic importance of M. hyopneumoniae?

Answer 15

30-80% have it on slaughter with an increasing impact on consistency of product as decreases FCE and increases variation in growth

Question 16

What is the economic impact of late onset PCV2?

Answer 16

Just before slaughter pig drops dead so lose full cost of producing pig up to slaughter weight and get nothing back
