Effects of oral administration of IFNT on 24-h energy expenditure in 10-week-old ZDF rats
| Oral IFNT dose (μg/kg BW/day)
|
|||
|---|---|---|---|
| 0 | 4 | 8 | |
| O2 consumption (L/h/kg BW) | 1.44 ± 0.01b | 1.46 ± 0.01b | 1.50 ± 0.01a |
| CO2 production (L/h/kg BW) | 1.17 ± 0.01 | 1.16 ± 0.01 | 1.19 ± 0.01 |
| Respiratory quotient (CO2/O2, v/v) | 0.815 ± 0.001a | 0.796 ± 0.001b | 0.794 ± 0.001b |
| Heat production (kcal/kg BW/h) | 6.85 ± 0.04b | 6.92 ± 0.05b | 7.12 ± 0.04a |
Data are the hourly means ± SEM, n = 6 per treatment. Energy expenditure was determined over a 24-h period in 10-week-old ZDF rats, during which food and drinking water containing the respective doses of IFNT were provided.
