Stress - Factors and Control in Livestock

The Future

Future research interactions will allow for the determination of:

• relationships between the environment and animal performance

• the effects of environmental toxins and procedures for relief

• critical endpoints for production, reproduction and immune functions affected by environmental stress

• animal or species sensitivity to environmental stressors and development of:

• genetic markers that identify environmental stress in livestock

• strategies for stress relief that contribute to animal health and well-being

• nutritional regimes to produce efficient growth and development in different environment

BEC Goals


• Biosensor technology that allow for real-time assessment of health status for domestic animals

• Integrated systems that utilize animals thermal balance, ambient conditions, and predicted weather patterns to operate animal comfort systems

• Animal management and comfort systems that reduce environmental stress to enhance animal health and performance

• Understanding of changes in animal gene expression associated with environmental stress

• Scientists who will develop practical solutions for long-term problems of climate change that are associated with global warming and air quality

Today's Challenges

Annual impact of environment on health and general well-being of animals in agriculture totals is at least $8 billion.

Summer heat stress reduces milk production rate and reproductive efficiency of dairy cows to produce an annual loss of $5-6 billion.

More than 22 million acres of fescue produced for over 7 million cattle are infected with a fungus. Consumption of infected fescue and exposure to heat stress produces reproductive losses and reduced weight gain that results in a $600 million annual loss to beef cattle producers.

Heat stress depressed profitability of swine production, with reduced feed intake, growth rate, lean tissue accretion, lactation.
