fce: Feed conversion efficiency (FCE)

In aquacultuR: A Comprehensive R Tool for Zootechnical Metrics

Feed conversion efficiency (FCE)

Description

A function that calculates the feed conversion efficiency (FCE), which is the inverse of the feed conversion ratio (FCR). As FCR, this metric measures how effectively cultivated species convert feed into weight. However, contrarily to FCR, the higher the FCE the more efficient the feed conversion is.

Usage

fce(ibw, fbw, feed, dm = 1)

Arguments

ibw	numeric; value that is providing the initial body weight in grams.
fbw	numeric; value that is providing the final body weight in grams.
feed	numeric; value providing the total feed fed in grams during the experiment.
dm	numeric; value indicating the dry matter content of the feed. Value in the interval of (0:1). Default is 1.

Value

a numeric value that is the feed conversion efficiency (FCE)

Examples

# Feed intake = 1500 g
# Feed dry matter = 0.96 g/g (= 96%)
# Initial bodyweight = 100 g
# Final bodyweight = 1000 g

fce(100, 1000, 1500, 0.96)
