With Correct Answers
What are the components of the epidemiologic triad and what are they
| | | | | | | | | | | |
influenced vy - CORRECT ANSWER✔✔-host, agent, environment and
| | | | | | | |
they're influenced by management practices
| | | |
when does disease occur - CORRECT ANSWER✔✔-when there is an
| | | | | | | | | |
imbalance in the tried | | |
what group of animals are most susceptible to disease - CORRECT
| | | | | | | | | | |
ANSWER✔✔-newborns and postpartum females | | |
Why does disease peak at the second week after birth in dairy calves -
| | | | | | | | | | | | | |
CORRECT ANSWER✔✔-first week they have passive immunity through
| | | | | | | |
mothers colostrum and we begin to vaccinate calves starting week 2 so
| | | | | | | | | | | |
there's a lot of immune responses coupled with stress
| | | | | | | |
what disease has the highest incidence rate in calves - CORRECT
| | | | | | | | | | |
ANSWER✔✔-pneumonia
,Why is colostrum crucial in the first few hours of life - CORRECT
| | | | | | | | | | | | |
ANSWER✔✔-the calf has a high capacity to absorb Igs from the GIT and| | | | | | | | | | | | |
as time goes on the GIT becomes less permeable to Igs
| | | | | | | | | |
What kind of placenta do cows have - CORRECT ANSWER✔✔-
| | | | | | | | |
synepitheliochorial
how many layers are there in the synepitheliochorial placenta? -
| | | | | | | | | |
CORRECT ANSWER✔✔-5-6 between maternal and fetal blood @ sites of
| | | | | | | | |
attachment
|
what does this mean for transfer of Igs while fetus is inside the womb? -
| | | | | | | | | | | | | | |
CORRECT ANSWER✔✔-too many layers for Igs to pass from mum to
| | | | | | | | | | |
fetus so they must come from colostrym
| | | | | |
what are some management practices that affect newborn disease
| | | | | | | | |
susceptibility - CORRECT ANSWER✔✔-1. age | | | |
2. feeding
|
3. environment
|
4. Vx status
| |
5. weaning
|
when is incidence of disease most prevalent in postcalving females -
| | | | | | | | | | |
CORRECT ANSWER✔✔-1-3 weeks after calving
| | | |
,what disease has the highest incidence rate in dairy cows - CORRECT
| | | | | | | | | | | |
ANSWER✔✔-metritis
when is the transition period - CORRECT ANSWER✔✔-3 weeks before
| | | | | | | | | |
and 3 weeks after calving
| | | |
what is the transition period - CORRECT ANSWER✔✔-a period in which
| | | | | | | | | | |
there's a transition between two different metabolic states
| | | | | | |
When is a cow in a negative energy balance? - CORRECT ANSWER✔✔-
| | | | | | | | | | |
post-calving because the cow is not consuming enough to meet | | | | | | | | | |
increased nutrient requirements associated with lactation
| | | | |
How does the cow compensate for not getting enough nutrients -
| | | | | | | | | | |
CORRECT ANSWER✔✔-she mobilizes her own fat and bone stores so
| | | | | | | | | |
she drops in BCS and BW
| | | | |
so what factors during the transition period contribute to increased
| | | | | | | | | |
incidence of disease - CORRECT ANSWER✔✔-1. lower FI
| | | | | | |
2. high nutrient concentration being secreted into milk
| | | | | | |
3. hormonal changes
| |
, What kind of hormone changes are associated with the transition
| | | | | | | | | |
period - CORRECT ANSWER✔✔-increased growth hormone, decreased
| | | | | | |
insulin and decreased IGF1 (insulin growth factor 1)
| | | | | | |
why is glucose important to lactation - CORRECT ANSWER✔✔-turns to
| | | | | | | | | |
lactose i in the mammary gland and is responsible for milk volume
| | | | | | | | | | |
How does the cow account for lost energy to milk production - CORRECT
| | | | | | | | | | | |
ANSWER✔✔-fat mobilization where there is an increase in
| | | | | | | | |
nonesterified fatty acids and ketone bodies in the blood to restore
| | | | | | | | | | |
energy
What else can the cow breakdown to restore energy - CORRECT
| | | | | | | | | | |
ANSWER✔✔-muscle which is what leads to a decreased BCS | | | | | | | |
What deficiencies are often associated with the cow not consuming
| | | | | | | | | |
enough nutrients postpartum - CORRECT ANSWER✔✔-caloric, amino
| | | | | | |
acids and serum Ca2+
| | |
what is the overall effect of these deficiencies - CORRECT ANSWER✔✔-
| | | | | | | | | |
immune system becomes compromised due to the ability of neutrophils
| | | | | | | | |
|to fight disease and infection being impaired
| | | | | |
