Impact of Disease on Performance Flashcards
What are the different ways disease can be detected?
At the abattoir
On farm
Medicines usage
How is disease detected at the abattoir?
BPHS abattoir monitoring scheme give report 24 hours post abattoir submission with results of lungs, liver and other disease findings
How is disease detected on the farm?
Mortalities/clinical cases
Days to slaughter
FCE
What can cause pyaemia in pigs?
Tail biting as bacteria travels up lesions into the blood and bacteria are deposited in the capillary beds
What bacteria causes gun shot wounds to lungs?
Actinobacillus pleuropneumoniae
What are the financial impacts of disease?
Treatment costs
Vaccination costs
Vet costs for diagnostics
Mortality
What costs of disease can be hard to quantify?
Suboptimal growth/ADG/days to slaughter
Food conversion efficiency
Secondary infection
Overhead costs
What are some other impacts of disease other than financial?
Reduced FCE impact on environment
Supply of standardised product decreases
Public perception
What are the characteristics of PRRS?
Multiple ages affected
Abortions, increased pre-weaning mortality, respiratory disease of growers
How does PRRS cause losses?
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
What does PED stand for?
Porcine epidemic diarrhoea
What is PED?
Coronavirus with no cross protection from respiratory or TGE with 100% mortality in neonatal pigs and scour in others with varying severity
What impact has PED had on trade?
Voluntary ban on live animal imports to UK
Not importing feed/semen
What does Mycoplasma hyopneumoniae cause?
Consolidation of cranial lung lobes with mild cough in uncomplicated cases
Attaches to cilia of mucociliary escalator
What is the economic importance of M. hyopneumoniae?
30-80% have it on slaughter with an increasing impact on consistency of product as decreases FCE and increases variation in growth
