Digestibility of a feed ingredient

Description

This dataset contains example data for the determination of the apparent digestibility of feed ingredients by using a reference diet and replacing a part (usually 30 The dataset is based on Bureau et al. (1999) but was presented in its complete form in Bureau & Hua (2006).

Format

A tibble with one row and eight columns

diet_reference: character; reference feed identifier.
ingredient: character; feed ingredient identifier.
adc_reference: numeric; apparent digestibility coefficient of the reference feed. The data is a value between 0 and 1.
adc_test: numeric; apparent digestibility coefficient of the test feed. The data is a value between 0 and 1.
dm_reference: numeric; mass fraction of dry matter in the reference feed. Data reported as value between 0 and 1, corresponding to g/g.
dm_ingr: numeric; mass fraction of dry matter in the feed ingredient. Data reported as value between 0 and 1, corresponding to g/g.
CP_reference: numeric; mass fraction of crude protein in the pelleted reference feed reported as value between 0 and 1, corresponding to g/g.
CP_ingr: numeric; mass fraction of crude protein in the feed ingredient. Data reported as value between 0 and 1, corresponding to g/g.
