Livestock Wintering: Locating and Managing your Site to Make it Sustainable


A sustainable wintering system provides livestock with essential needs—food, water, and shelter—while balancing production efficiency, farm profitability, and environmental stewardship. It includes:
  • Integrated Management: Combines feeding, infrastructure, and resource strategies to create flexibility and maximize profits.
  • Environmental Responsibility: Minimizes negative impacts on land and water resources, addressing concerns of neighboring communities and consumers.
  • Public Scrutiny: Livestock practices affect not only farms but also the broader public, making sustainability a shared responsibility.
Production Benefits of a Sustainable System
·        Lower expenses for spreading and distributing manure across the farm.
·        Livestock thrive in a natural, low-stress environment, resulting in:
o   Fewer health problems and better overall performance
·        Utilize on-pasture feed sources such as:
o   Stockpiled forages, Cereal and corn swaths and/or bale grazing
→ Reduces hauling and handling costs
·        Manure acts as “farmer’s gold”, enriching soil fertility.
·        Applying manure at appropriate rates on marginal or unproductive land can make it productive.
Environmental Risks of Livestock Concentration
Manure and Nutrient Accumulation:
  • Extended confinement or feeding in concentrated areas leads to localized manure buildup and excess nutrients which can run off into surface waters, carrying nutrients and microorganisms.
Groundwater Vulnerability:
  • High risk when manure accumulates on shallow soils over bedrock or coarse sand/gravel near the surface.
  • Nutrients and pathogens can leach into groundwater systems.
 
Pathogen Concerns:
  • Manure may contain harmful bacteria and parasites:
    • E. coli (including O157:H7): Causes severe illness in humans (diarrhea, fever, kidney failure, sometimes death).
    • Cryptosporidium and Giardia: Cause gastrointestinal sickness, diarrhea, and weight loss in humans and animals.
Wildlife and Habitat Impact:
  • High livestock densities can damage wildlife habitat, trample shorelines, and degrade waterways through runoff.
Choosing a Sustainable Wintering Site
The ideal wintering site should be:
  • Feasible for your operation
  • Healthy and comfortable for livestock
  • Safe for the environment
Factors to Consider
  • Land Characteristics: Contours, soil type, water resources
  • Herd or Flock Requirements: Size and nutritional needs
  • Existing Infrastructure: Combine current facilities with new options such as:
    • Portable wind fences
    • Temporary fencing for paddocks and feeding
    • Alternative watering stations
Goals of Sustainable Site Selection
  1. Protect Sensitive Areas:
    Avoid or restrict livestock access to:
    • Slopes
    • Sandy soils
    • Non-vegetated areas
    • Riparian zones
    • Woodlots
    • Land already nutrient-rich from manure
  2. Maximize Land Use:
    Utilize a greater portion of your land base and in-field feed sources for an extended period throughout the year.
Site Selection Recommendations
1. Water Management
  • Locate watering stations away from natural water sources to prevent contamination.
  • Use deeply buried pipelines to central pasture locations.
  • Consider solar or wind-powered pumps for reliable water supply in remote areas.
2. Ground Cover
  • Choose sites with good vegetation or crop residue to filter nutrients and sediment from runoff.
3. Slope Considerations
  • Select areas with less than 2% slope to minimize runoff and erosion.
  • If slope is unavoidable:
    • Place bedding and feeding sites away from waterways.
    • Use naturally elevated ground for high-traffic areas to control drainage.
4. Soil Type
  • Clay soils reduce leaching risk.
  • Avoid sandy soils, gravel, shale, or sandstone outcrops—they increase leaching and require extra management.
5. Water Table & Flood Risk
  • Avoid areas with high water tables or spring flooding history to prevent nutrient and bacteria migration into groundwater or surface water.
Strategies for Maintaining a Sustainable Wintering Site
1. Utilize More of Your Farm
  • Expand wintering areas to reduce manure accumulation and improve nutrient distribution.
  • Healthy vegetation growth the following summer indicates proper manure management; poor regrowth suggests animal density is too high.
2. Manage Manure
  • Remove and spread manure from bedding, watering, feeding sites, and high-traffic areas.
  • Follow your farm’s nutrient budget:
    • Calculate manure application based on crop needs.
    • Use soil tests and provincial guidelines (e.g., Tri-Provincial Manure Application and Use Guidelines).
3. Keep Animals Moving
  • Move livestock every few days if possible; at minimum, relocate once or twice per winter.
  • Rotate wintering sites annually to prevent overuse.
4. Use Portable Infrastructure
  • Wind fences and portable fencing allow temporary sites and flexible movement.
  • If sites cannot be moved, relocate bedding and feeding areas frequently to spread manure.
5. Adjust Feeding Approach
  • Consider extended grazing programs that take animals to the feed.
6. Establish Satellite Feed Storage
  • Store feed in multiple locations across the farm to enable feeding in different areas and reduce pressure on central sites.
7. Stream Crossings and Alleyways
  • Use gravel stream crossings with control gates to reduce erosion and protect waterways.
  • Avoid placing alleyways on land prone to run-off or seepage.
  • Limit alley way use to prevent soil copmpaction and nutrient buildup.
8. Bedding Management
  • Apply ample bedding litter to absorb nutrients and reduce leaching and run-off.
9. Vegetative Cover
  • Increase vegetation wherever possible to act as a natural filter for run-off and sediment.
  • Seed crops in these areas to utilize nutrients and provide high-quality feed.
10. Buffer Zones
  • Establish permanent vegetation buffers around sensitive areas such as water bodies to protect water quality.
11. Wellhead Protection
  • Maintain a minimum 30-foot buffer between livestock and wellheads.
  • Ensure proper drainage away from wells and secure cribbing and lids.
12. Water Flow Diversion
  • Divert off-site water flow around bedding and feeding areas to:
    • Reduce run-off and mud
    • Improve animal health (prevent scours in newborns)
    • Lower bedding replacement costs

13. Control Water Flow

  • Use landscaping with ditches and channels to direct water leaving the site toward less-sensitive areas.
14. Manure Management
  • Remove and spread manure early in spring to prevent runoff or seepage.
  • Avoid spreading on:
    • Erosion-prone land
    • Areas draining directly into waterways
    • Land adjacent to permanent water bodies or major field drains
15. Fencing for Control
  • Install portable or permanent fencing to:
    • Manage feeding and animal distribution and control density and rotation
    • Protect sensitive areas
    • Improve manure distribution
16. Watering Innovations
  • Explore modern watering systems for portability and efficiency.
17. Wildlife Habitat Considerations
  • Plan to maintain and protect wildlife habitat while managing livestock operations
