What is an important environmental factor affecting the risk of a feedlot calf developing respiratory disease?
Question 2
1 / 1 point
Which of the following is FALSE regarding feedlot cattle?
Question 3

Which is the most important host risk factor for the development of neonatal calf diarrhea?
Question 4
1 / 1 point
In 2016, a herd of 100 beef cows had trouble with fertility, achieving a less than optimal 90% pregnancy rate. They calved the herd out
successfully, with no stillbirths, and had no sets of twins. However, they did have 18 calves develop scours during the first month of
life, one of which died from dehydration. What was the morbidity frequency in the first month of life?

– goats)
Question 9

Done
How long calves were in transport prior to arrival
Vaccine history
Stocking density
Body condition score
If the calf was 'pre-conditioned'
Lighter weight calves may spend time at a backgrounding facility prior to entry Castration and dehorning should be done immediately on arrival to avoid setbacks The goal in a feedlot is rapid and efficient gain of lean muscle mass
Growth implants may be used to increase the efficiency of lean muscle gain The greatest risk period for respiratory disease is in the first month after arrival
Poor air quality
If enterotoxogenic E. coli
(ETEC) is suspected
Colostrum management: quality, quantity, cleanliness, quickness
Cleanliness of the environment
Purchase of replacement animals during calving season

Feeding on the ground
Feeding cattle mineral to sheep
Short tail docking
Unvaccinated dams – should be boostered prior to lambing
Inadequate iodine in the ration
Necessary cause
Sufficient cause
Proximate cause
Both necessary and sufficient
None of the above
Ewes suffering from parasitism will give birth to lambs with high fecal egg counts
Frequent deworming of all animals in a flock is recommended for control
Anemia is an important sign of parasitism
GIN is a major problem for flocks that house entirely indoors
GIN typically only infects young lambs; ewes are rarely infected
Removing newborns from infected dams at birth and rearing separately will help break the cycle of infection
Poor diagnostic test accuracy for these diseases means it is not possible to have an effective eradication program
Most herds/flocks in Ontario are free of these diseases but they are reportable
All animals with abscesses should be segregated or culled
Animals with a 'Q' codon on gene 171 are susceptible
