Calculate daily nitrogen intake

Calculates the daily nitrogen intake per head (kg N/head/day) as the product of feed dry matter intake (DMI) and diet nitrogen content.

Usage

calc_nitrogen_intake(ration_intake, ration_nitrogen)

Arguments

ration_intake

Numeric. Average daily dry matter intake of feed (kg DM/head/day).

ration_nitrogen

Numeric. Average nitrogen content of diet (kg N/kg DM).

Value

Numeric. Daily nitrogen intake (kg N/head/day).

Details

This approach follows the IPCC Tier 2 approach and estimates ration_intake as follows:

\(nitrogen\_intake = dry\_matter\_intake \times diet\_nitrogen\)

This function is part of the run_nitrogen_balance_module().
