A filtering algorithm for accurate determination of feed intake dynamics

Résumé

Background : Feed intake is a useful measurement in many types of livestock studies. This variable can be obtained by measuring changes in feed weight (weight_m) over time using a weighing platform. The resulting data are a mixture of stable and variable (during animal or human interactions with the platform) feed weights. Results : This article proposes an algorithm that extract the stable parts, allowing accurate computing of feed intake. A GPL-3.0+ implementation of this algorithm in R is provided. Application is illustrated using individual data from cows, goats and mice Conclusions : Feed intake can be computed from weighing platform data in various species using our method.
