ENVIRONMENTAL TEMPERATURE

thermogenesis

In colder environments, animals often mobilize adipose tissue (fat stores) to generate heat and support processes involved in ____ (heat production).

fatty acids

The breakdown of triglycerides in adipocytes (lipolysis) releases ____, which can be used for energy and converted to heat in specialized fat stores like brown adipose tissue.

increased

As the ambient temperature drops below the thermoneutral zone, animals experience ___ energy requirements. This is due to the need to produce more heat to maintain body temperature and support normal biological functions.

intake

To meet these increased energy demands, animals often increase their feed ___. The higher caloric intake helps fuel the processes necessary for thermoregulation and support bodily functions under stress.

efficiency

Feed ___ (the ratio of feed intake to weight gain) tends to worsen in cold conditions. This is because dietary nutrients are repartitioned (redirected) away from growth and fat deposition and toward heat production.

expenditure

In this context, animals will prioritize energy ____ for maintaining body temperature over growth or fat accumulation, leading to a lower weight gain per unit of feed consumed.

stress

As ambient temperature increases above the thermoneutral zone, animals typically experience a decrease in feed intake. This is because heat ___ can lead to reduced appetite and the body needs to minimize energy expenditure to cope with the elevated temperatures.

growth.

With increased temperature, the body reduces its need to produce heat. This results in an inhibition of thermogenesis (heat production), which also impacts ___.

coping

Growth processes are often suppressed under heat stress, as the body focuses more on __ with environmental conditions rather than on growth.

inhibition

Adipose tissue mobilization (especially in cold environments) and ___ of growth (especially in heat stress) are part of the body’s efforts to maintain energy balance under varying temperature conditions.

ambient

Lipid metabolism is highly influenced by ___ temperature, with the mobilization of fat stores occurring in cold conditions to support thermogenesis, and reduced fat deposition and growth in hot conditions as the body shifts focus toward dealing with heat stress.
