Introduction Lameness Structure ◦ Phase 1 ◦ Phase 2-3 Prevention ◦ Lameness Control program Effect on productivity Conclusion
Increasing problem in dairy cattles Painful for animal Effects productivity:- Milk production- Pregnancy
3 phases of lameness process:1. Initial activation phase2. Local mechanical damage3. Progressive local mechanical damage of bone and support structure.
Associated with a systemic metabolic insult Vasoactive mehanism increases digital pulse and total blood flow. Expansion of the corium
Associated with the vascular system. Fewer nutriens and less oxygen reaches to the epidermal cells. “Heart attack” of the feet -> phase 3, where bone shifts in position.
Locomotion scoring - reproducible technique, it consists of watching each cow walk on an even non-slip surface. (sound, uneven/slow, lame Routine foot trimming – likely the most important control measure for reducing lameness.
Monitoring lameness incidence and causes A planned foot trimming program Strategic, regular footbathing Prompt treatment of lame cows Specific management of first lactation cattle Clean and comfortable walking surface for the cows.
Decline in milk production 0,5 to 1,5 lts/day Causes late pregnancy Prolongs calving interval by 35-50 days.
Animals whose lying time after calving gets redused are more likely to suffer claw horn diseas in peak or mid lactation. Lameness can be easily prevented with right strategy. As an huge effect on animal health and production.
