Assignment Structure (~3,200 words | 13 Sections)
| Section | Content |
|---|---|
| 1. Introduction | Importance of estrus detection, declining detection rates, need for automation |
| 2. Estrous Cycle | 21-day cycle phases, hormonal basis (E2, P4, LH), why activity increases |
| 3. Traditional Methods | Visual observation, tail paint, teaser bulls, kamar patches, hormonal methods |
| 4. Pedometers | Principles, types (mechanical vs. electronic), placement, operation, data interpretation, performance table |
| 5. Accelerometers | Triaxial sensors, ear tag vs. neck collar vs. leg vs. bolus, mechanism, commercial systems |
| 6. Farm Software Integration | Data flow diagram from sensor → transponder → server → farm manager alert |
| 7. Commercial Systems | Comparison table of 7 major systems (Heatime, SenseTime, AfiFarm, CowManager, Smartbow, etc.) |
| 8. Pedometer vs. Accelerometer | Head-to-head comparison table |
| 9. Factors Affecting Performance | Animal, environmental, and system factors |
| 10. Reproductive Efficiency | Detection rate improvement, optimal AI timing, economic benefit |
| 11. Limitations | Cost, false alerts, silent estrus, technical challenges |
| 12. Recent Advances | AI/ML, acoustic sensors, IRT, rumen boluses, computer vision |
| 13. Conclusion | Summary |
| References | 10 peer-reviewed citations (2019–2025) |
Diagrams included: hormonal cycle graph (real image), pedometer system flow diagram, 3-axis accelerometer orientation diagram, full automated system architecture diagram, activity index graph, and device comparison tables. All references are from PubMed-indexed journals (2019–2025).
