Assignment: Automated Estrus Detection Using Activity Monitors and Pedometers
Comprehensive DVM-level assignment — 19 sections
What's included:
| Section | Content |
|---|---|
| Estrous Cycle Biology | 21-day cycle phases, hormonal profiles (P4, E2, LH, GnRH), activity-behavior link |
| Economic Importance | 21-day pregnancy rate equation, cost of missed heats |
| Traditional Methods | Visual, tail paint, chin-ball, Kamar patch — efficiency comparison table |
| Pedometers | Working principle, step-count thresholds, types, commercial brands (AfiAct, Enfotra) |
| Accelerometers | 3-axis physics, collar vs. ear tag vs. leg placement, multi-parameter monitoring |
| Flowcharts | 6 original flowcharts: pedometer workflow, accelerometer system, full farm-to-alert architecture, AI timing, decision algorithm, false-positive guide |
| Performance Metrics | Sensitivity/specificity definitions, Smartbow data (91.6% sensitivity from PMID 33685699) |
| Comparison Tables | All detection methods side-by-side; pedometer vs. accelerometer |
| Limitations | Technical, animal-related, and management challenges |
| Future Perspectives | ML algorithms, computer vision, inline progesterone, smartphone integration |
| References | 7 peer-reviewed citations including 2 PubMed-verified 2021–2025 reviews |
Images included:
- Figure 1: Bovine estrous cycle hormonal simulation (P4, IGF-I, LH, E2 cycles)
- Figure 2: Transrectal ultrasound of bovine uterine horn for estrus confirmation
