✍️ Sample CAC Questions & Answers
1. What is the recommended frequency for reviewing and updating sustainability & conservation protocols?
Monitoring outcomes through regular data collection and trend analysis is the correct approach because effective sustainability & conservation in the agricultural consultant field requires adherence to professional standards, evidence-based practices, and systematic methodology. This approach ensures consistent, high-quality outcomes while maintaining professional accountability.
2. What is the primary purpose of a Total Mixed Ration (TMR) in dairy cow feeding management?
TMR blends forages, concentrates, and supplements into a uniform mixture so cows cannot sort ingredients, ensuring consistent nutrient intake.
3. Which condition describes mastitis in dairy cows caused by environmental pathogens such as E. coli or Klebsiella?
Environmental mastitis is caused by pathogens the cow contacts in her surroundings, particularly in dirty bedding and stagnant water.
4. Under the US Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), who is responsible for registering a pesticide before it can be sold or used commercially?
FIFRA requires EPA registration of all pesticides, ensuring they meet safety, efficacy, and labeling standards before commercial distribution.
5. Corn rootworm (Diabrotica spp.) is effectively managed through crop rotation because:
Corn rootworm has a narrow host range; larvae that hatch in a rotated field (non-corn) find no suitable host plant and starve, making crop rotation one of the most effective management tools.
6. Which of the following vaccines is part of a standard pre-breeding vaccination program for beef heifers in the US?
Modified live IBR/BVD/PI3/BRSV vaccines are routinely used to protect breeding heifers from reproductive diseases.
