Q14. A cow shows clear signs of oestrus. The farmer asks why the timing of artificial insemination is critical. The most appropriate explanation is that conception depends on proper synchronisation with:

A. Maximum feed intake

B. Peak milk fat percentage

C. Hoof growth

D. Ovulation and the viable period of sperm and ovum

E. Maximum body temperature

Q15. A goat breeder selects animals using growth rate, reproductive performance, disease resistance and body conformation rather than relying on a single characteristic. This is an example of:

A. Random mating

B. Multiple-trait selection

C. Genetic drift

D. Artificial incubation

E. Inbreeding without selection

Q16. A poultry farm suddenly experiences increased mortality and respiratory signs. What should be the immediate management priority:

A. ₹3 lakh

B. ₹4 lakh

C. ₹5 lakh

D. ₹7 lakh

E. ₹19 lakh

A. Price discovery

B. Forward contracting

C. Hedging

D. Distress sale

E. Vertical integration

C. Availability of collateral alone

D. Number of family members

E. Brand of milking equipment

🧠 PROFESSIONAL REVISION — 20 MUST-KNOW POINTS

━━━━━━━━━━━━━━━━━━

🧬 1. Heterosis

Superior performance of an F1 hybrid relative to the parental average, and in some cases the better parent.

🌾 2. Pure-line development

Repeated selfing and selection increases homozygosity and helps develop genetically uniform lines.

🌱 3. Male sterility

Useful in hybrid seed production because it prevents self-pollination of the female parent.

🌾 4. Legumes

Suitable legumes can contribute biologically fixed nitrogen through symbiotic associations.

🍎 5. Parthenocarpy

Fruit development without normal fertilisation.

🍊 6. Harvest maturity

Correct maturity is essential for quality, transportability and post-harvest life.

🦠 7. Disease triangle

Host + pathogen + favourable environment = disease development.

🌿 8. Resistance breakdown

Pathogen evolution or selection can overcome previously effective host resistance.

🚜 9. Combine harvesting

Major operations include cutting/feeding, threshing, separation and cleaning.

🌾 10. Seed drill

Provides relatively controlled seed placement with respect to depth and spacing.

📦 11. High-moisture grain

Promotes heating, microbial growth and deterioration during storage.

🏚️ 12. Grain storage

Proper drying, hygienic storage and monitoring are essential for reducing post-harvest losses.

🐄 13. Artificial insemination

Allows genetic improvement using semen from selected superior males.

🧬 14. Breeding timing

Successful conception depends on appropriate timing relative to ovulation.

🐐 15. Multiple-trait selection

Selection can consider several economically important characteristics simultaneously.

🐔 16. Poultry biosecurity

Isolation, hygiene, controlled movement and veterinary diagnosis are critical during disease events.

🐟 17. Polyculture

Compatible species utilise different ecological and feeding niches in the same production system.

💰 18. Gross margin

Gross receipts − variable costs.

📉 19. Distress sale

Forced sale under financial or storage constraints can result in an unfavourable price.

🏦 20. AFO credit appraisal

Technical feasibility alone is insufficient; repayment capacity and cash flow are critical.
