Document Summary

Review: 1g carbs = 4 kcal, 1g protein = 5-5. 5 kcal, 1g fat = 9 kcal. Is higher in summer than in winter: bmr in newly hatched birds, usually low. Maintenance energy: maintenance energy requirements, me intake at which bw and composition remain constant in a healthy, non-reproducing animal/bird living in its normal environment, daily energy expenditure (dee) = bmr + activity + thermoregulation + food metabolism. Increased feather-wear while tobogganing may waddle on hard snow: energy required = 6 kcal, all species, all bws, all agnles of ascent. Increasing food intake: incubation, heat is needed to start embryonic development in the egg and allow it to continue, heat required depends on: Increase appetite (increase in metabolic heat: use shelter from wind (decrease in convective cooling), shelter from rain and snow (decrease in evaporative cooling, stand in sun (increase in solar heat, shivering (increase in internal body heat) Increase in metabolic rate (increase in heat production)
