Calculate diet gross energy contribution for a ration component

Computes the contribution of a single feed component to diet gross energy content by weighting feed gross energy by its ration composition share.

Usage

calc_ration_gross_energy(feed_ration_fraction, feed_gross_energy)

Arguments

feed_ration_fraction

Numeric. Proportion of a specific feed component in the total ration, expressed as its fraction of diet dry matter intake (fraction). Within each herd_id and cohort, proportions should sum to 1.

feed_gross_energy

Numeric. Gross energy content of a feed component, representing the total chemical energy released upon complete combustion of the feed (MJ/kg DM).

Value

Numeric. Contribution of the feed component to total diet gross energy content (MJ/kg DM).

Details

The gross energy contribution is defined as: $$diet\_gross\_energy = feed\_ration\_fraction \times feed\_gross\_energy$$
