Calculates the manure excretion values for a growing heifer with information from the ration formulation.
Parameters#
- body_weightfloat
Body weight of the current animal, kg.
- fecal_phosphorusfloat
Amount of fecal phosphorus excreted by the current animal, g.
- urine_phosphorus_requiredfloat
Amount of phosphorus required for urine production, g.
- methane_modelstr
Methane model used for methane emission calculations, including Boadi, IPCC.
- nutrient_amountDict[str, float]
Amounts of nutrients in pen ration, calculated per animal, see Notes section for units.
- nutrient_concDict[str, float]
Concentrations of nutrients in pen ration, calculated per animal, percentages.
Returns#
- float
Total amount of phosphorus excreted by the given animal, g.
- AnimalManureExcretions
- A dictionary that contains the manure excretion values as specified
in the AnimalManureExcretions class definition.
