Maintenance nutrition refers to what?

Maintenance nutrition refers to what?

• A. Nutrition required for maintenance of current weight
• B. Nutrition required for maximum growth
• C. Nutrition required for reproduction
• D. Nutrition required for increased lactation

Answer: (A)

Maintenance nutrition is the amount of nutrients an animal needs to keep its body weight stable and support normal bodily functions under typical conditions. It reflects energy expenditure from basal metabolism plus daily activity and environmental factors, so when intake equals this level, the animal neither gains nor loses weight. This baseline differs from growth, reproduction, or lactation, which require additional nutrients beyond maintenance. Growth needs extra energy and protein to build tissue; reproduction adds demands to support fetal development and gestational maintenance; lactation increases energy and protein to produce milk.
