Bioenergetic Criteria for Meat Animal Environmental ManagementEntry ID: USDA0515
Abstract: The purpose of the "Bioenergetic Criteria for Meat Animal
Environmental Management" dataset is for providing information
on growing meat animals, evaluating dynamics of energetic
responses (e.g., thermoregulation, feed intake) in relation to
thermal thresholds for stress-reduced efficiency and
performance; assessing adaptive and compensatory capabilities
after exposure to thermal stress, including ... the effects of prior
conditioning; and evaluating and improving functional
relationships for performance responses to thermal conditions.
Collection Organization: USDA Agricultural Research Service
Collection Methodology: Thermal environments can strongly impact
bioenergetics (energy flows within the biological system).
Stress response dynamics, emphasizing short-interval measures of
thermoregulation, heat production/dissipation, feeding
activities, and physiological factors, are used to assess
nutritional and genetic interactions with thermal stressors, to
evaluate adaptive capabilities, and to determine the modifying
influences of such factors as age/weight and prior conditioning
on thresholds beyond which growing meat animlas are unable to
fully adapt. Descriptive response relationships are
developed/refined between thermal stressors and reduced
performance/health as a basis for improved environmental
meanagement to enhance productive efficiency and animal
Collection Frequency: Ongoing research.
