Abstract

A dataset of 100 pigs, from the Piétrain NN Français line raised at the AXIOM boar testing station in 2020, was used. The farm was equipped with an automatic feeding system, recording individual weight and feed intake at each visit. We used a dynamic linear regression model to characterise the evolution of the energetic allocation factor (αt) which represents the link between the cumulative net energy available (estimated from feed intake) and cumulative weight gain during the fattening period. The data were imported using an R script to estimate the allocation factor for a given animal. The dataset and R script are useful resources to study feed intake, growth dynamics and the relationship between these two variables.

利用动态线性模型研究育肥猪体重和采食量的动态数据及能量分配因素
该研究使用了一个由100头猪组成的数据集,这些猪来自2020年在AXIOM公猪测试站饲养的pisamutrain NN franais品系。该养殖场配备了自动饲喂系统,在每次访问时记录个体体重和采食量。我们使用动态线性回归模型来表征能量分配因子(αt)的演变,αt代表了育肥期间累积净可用能量(从采食量估计)与累积增重之间的联系。使用R脚本导入数据以估计给定动物的分配因子。该数据集和R脚本是研究采食量、生长动态以及两者之间关系的有用资源。
