SAMPLE QUESTIONS FOR BCSE TEST
Here are 5 sample multiple-choice questions for the BCSE test, along with the correct answers and brief explanations:
Question 1:
What is the primary purpose of the California Mastitis Test (CMT) in dairy health diagnostics?
A) Identify clinical mastitis cases.
B) Detect subclinical mastitis cases.
C) Assess milk composition.
D) Quantify lactose levels.
Answer: B) Detect subclinical mastitis cases.
The CMT is designed to uncover subclinical mastitis cases that lack visible symptoms, ensuring comprehensive herd health surveillance.
Question 2:
What is the significance of elevated scores in the CMT?
A) Indicates healthy udder function.
B) Suggests a mild infection.
C) Points to severe mastitis.
D) Correlates with milk viscosity.
Answer: C) Points to severe mastitis.
Higher CMT scores indicate intensified mastitis severity, providing insights into somatic cell counts and infection gravity.
Question 3:
In the CMT methodology, why is the quantification of DNA in milk secretions crucial?
A) It assesses milk cellularity.
B) It measures milk acidity.
C) It identifies bacterial pathogens.
D) It determines milk fat content.
Answer: A) It assesses milk cellularity.
Quantifying DNA content is pivotal due to its direct correlation with white blood cell (WBC) levels, offering insights into milk cellularity and inflammation levels.
Question 4:
What is the primary role of the CMT reagent during the test?
A) Enhance milk flavor.
B) Break down somatic cells.
C) Create DNA gel.
D) Increase milk viscosity.
Answer: C) Create DNA gel.
The CMT reagent triggers cellular lysis and DNA gelation, leading to the formation of the gel that serves as a proxy for white blood cell count.
Question 5:
In assessing viscosity changes in the CMT, what does a higher viscosity value indicate?
A) Low milk cellularity.
B) Reduced inflammation.
C) Higher white blood cell count.
D) Lower somatic cell count.
Answer: C) Higher white blood cell count.
Elevated viscosity values indicate a higher presence of cells, suggesting an increased white blood cell count and potentially heightened inflammation levels.
