Oil‑Based Color‑Changing Veterinary Crayon for Livestock Estrus Detection
Oil‑Based Color‑Changing Veterinary Crayon — Efficient Livestock Heat Detection Tool for Commercial Farms
This oil-based veterinary estrus detection crayon is a practical marking tool for modern livestock farms to screen cattle, sheep, and pig heat status. It solves pain points of missed or incorrect heat judgment by manual observation and improves breeding conception rates.
Working Principle
Draw long marks on the animal’s rump or tail base. Once mounting behavior happens, friction will trigger an obvious color change on the mark. Farmers can quickly confirm whether livestock is in heat and reduce inspection errors.
Key Product Benefits
✅ Color‑change mechanism to reduce misjudgment
Special oil‑based wax formula resists light rain. Color only shifts under real mounting friction, helping you pick truly heat‑active animals and avoid ineffective breeding.
✅ Non‑toxic paraffin material for farm animals
Made of high‑purity eco‑friendly paraffin, non‑irritating for cattle, sheep, and pigs. Marks can be washed off with water without harming the animal's coat and skin.
✅ Multiple bright colors for livestock group management
Red, orange, blue, and green are available. Different colors help separate livestock groups and breeding stages for easier farm management.
Application Scenarios
Perfect for heat detection in dairy farms, beef cattle farms, sheep & pig farms. Also suitable for animal marking during vaccination, grouping, and health inspection. Check our livestock breeding supplies collection for more farm equipment solutions.
