The w33zl modder offers a script of around one hundred kilobytes allowing, on Farming Simulator 19, to display the essential information of your herds. Needs, productions, reproductions… the tool could quickly become essential for those who are thoroughly into breeding.
Mods like this, there were already, like AnimalsHUD by xDeekay, but Stockman has the merit of being well integrated into the original HUD and especially of being more complete. Stockman HUD gives you an overview of your herd with alerts and summaries for the most important stats. The basic idea is to display the most important information so that you can be efficient when taking care of your livestock.
The icons on the screen display the general status and performance of each type of animal (the color of the icon indicates the general condition). Alerts give you short messages about the most urgent things to take care of (lack of food, shortage of water, etc.). The mod automatically displays a summary for your animals when you approach a pen. Optionally, you can choose to view a full overview of all your pens, no matter where you are.
For herd feeding, Stockman displays the remaining feed information not as a percentage but as a number of days remaining. Really great if you play with the seasons mod, where every day counts.
