Grassland Evaluation Contest Rules - Pasture Improvement

  1. What changes should be made in livestock management?
    1. Continue present management
    2. Reduce livestock numbers
    3. Change calving season to different time of year
    4. Shorten calving season to a period of < 90 days.
    5. Provide higher quality pasture
    6. Switch to a management-intensive rotational grazing system

Continue present management: Use this option when the livestock management practices matches with the landowners goals and forage management.

Reduce livestock numbers: Use this option when the livestock numbers exceed the carrying capacity of the farm even when calculated for a different grazing management system. Calculating the forage requirement using the percentage utilization for management-intensive grazing may allow the farmer to keep the herd at it.s current size if livestock numbers are too high for a continuous grazing system.
NOTE: The goals stated by the landowner may also dictate reducing livestock numbers regardless of the carrying capacity of the farm, but this will be specifically stated for the contest.

Change calving season to a different time of year: Spring or fall calving are recommended for Missouri conditions. Summer calving should be avoided due to the potential of low cow conception rates caused by hot weather.

Shorten calving season to a period of <90 days: Use this option when the calving season is spread out over more than one season for that single herd or when year-round calving is being practiced.

Provide higher quality pasture This option should be chosen when the farm scenario states that the farmer has problems with low weight gains, low conception rates and/or low weaning weights or when fescue endophyte is a problem.

Switch to a management-intensive rotational grazing system Switching to a management-intensive rotational grazing system may improve forage availability if the carrying capacity of the farm is exceeded under continuous grazing management. Management-intensive grazing can also reduce problems with spot-grazing in pastures. This option should be chosen when there is a shortage of forage in more than one season.
