Condemnations at slaughtering plant

Question 1

what is condemnation

Answer 1

• judged unsuitable for human consumption
• by canadian food inspection agency
• important record for broilder producer ( cant fix what you dont know)

Question 2

what is cellulittis

Answer 2

• infection under the skin cause by a scratch = subcutaneous infection caused by E. coli
• related to growth becasue skin is thinner and easily more scratched
• management and scratching causes = equipent (nails), handeling and stocking density, management practices - load Vs quiet

Question 3

what happens during a liver condition

Answer 3

• inclusion body - hepatitis - swollen liver
• necrotic enteritis (see a lot more raised without antibiotic)
• perihepatitis (e coli)

Question 4

other condemnations

Answer 4

• respiratory conditions
• dark coloured carcasses - inadequate blleding
• emaciation
• bruising
• leg conditions
• skin conditions
• abdominal oedema ascites

Question 5

what causes skeletal disease

Answer 5

• incidence
• casues = infection e.g osteomyelitis
• nutrion ( kalcium, phosphorus, vitamin D)
• trace minerals and B vitamins
• anti-nutritional factors
• environmental = photoperiod length
• growth rate
• genotype

Question 6

what is sudden death syndrome

Answer 6

• acute death syndrome flips over
• ventricular fibrillation (arrhythmia)
• incidence (males have a higher incidence, starts at 7 and peaks at 21 d)
• facotrs influencing ( growth rate and light- photoperiod length, light intensity doesnt effect this disease)
• nutrtion

Question 7

what is chronic heart failure (ascites)

Answer 7

• growth associated disease
• mortality dead on arrival, condemnatires
• chronic heart failure followed by ascites (related to ability to supply tissue with oxygen, cardiopulmonary function)
• factors influencing - altitude ( lower o2 heart workds harder) , growth rate ( heart working harder)

Question 8

what factors influence heart disease

Answer 8

• environment ( temperature, photoperiod length, ammonia/ dust)
• nutrition ( nutrient density, feed restriction, diet form, diet sodium content)
• genotype

Question 9

what are new issues in broiler production

Answer 9

• slow growth broilers ve conventionally reared broilers
• conventional growth rates may mean poor welfare (indications that behavioural expression is higher later in life if slow growing
• leg disorders may be lower
• need to determine if longer time in barn (environment, dust and wet litter) = issue for welfare

Question 10

raised with antibiotics incorrect issue and correct issue

Answer 10

• incorrect issue = there is a period to let them out of the system
• correct issue = bacteria developing a resistence
