Minimize the number of replacement heifers . High heifer replacement rates can greatly increase the cost of production, taking away resources available for producing cows. As mentioned previously crossbred females have greater longevity than straight bred animals. Proper supplementation and body condition score management will also reduce the number of open cows each year. Consideration must also be given to raising vs purchasing replacement heifers.
Open cows require less maintenance feed and generally have greater calving ease.
This decision will depend on why the animal was open, her genetic merit and the value of resources that particular year. Develop a sound herd health program . It is not recommended to cut corners when it comes to herd health. Low-cost producers try to shift their herd health expenditures to preventive medicine rather than treatment. Work with your veterinarian to establish management procedures that reduce herd health risks and develop a cost effective herd health plan.
