Ammonia Nitrogen Calculations |
| Nitrogen production as a factor of protein fed | = 6.25 x protein fed - nitrogen retained in tissues |
| Ammonia produced as a factor of feed fed (assuming commercial diets such as Salmonid) | = 0.03 x feed weight |
| % unionised ammonia of total ammonia | = 100 / (1 + antilog (pKa -pH)) |
| Where | |
| pH = pH value of sample | |
| pKa = 0.09018 + 2729.92 / (273 + T) | |
| T = Temperature oC | |
