We are Adaptingto Climate

Profitability

Definition

Adaptation: Adjustment or preparation of natural or human systems to a new or

changing environment which moderates harm or exploits beneficial opportunities.

(EPA)

Definition

Risk Management: The process of assessing risk and acting in such a

manner . . . so as to avoid or minimize loss associated with such risk. (Webster’s)

ExamplesChanges due to Climate and Weather

Rest of the Story

• Lots with shade (24 sq feet per head) had 0.2% death loss

• Lots with no shade averaged 4.8% death loss

• Other contributing factors– Weight of animals– Color of animals– Direction of slope on lots

Weathering Drought with Cow-Calf Grazing System (Daybreak Ranch, SD)

Five Point Drought Plan• Increase stored and standing

forages – diversification of grass species

• Changed grazing management to build resilience in soils and grasses (moisture and erosion)

• Store more hay• Monitor rain events• Adjust stocking density

Weathering Drought (Agriculture.com, 2013)

Geothermal Swine Gestation Barn in Western Minnesota

• 650 gestation to wean facility• Very Long Term Planning• Increased pigs per sow• Improved Health• Significant investment

Beef Herd Genetics Texas

Trends in Farm Genetics based on climate

• Tired of fighting the weather– Snow, cold, rain and mud, heat

waves

• Labor shortage• Moved over 2/3 of animals
