In automated milking with AMS can be identified various phases: 1. Animal Identification: the animal enters the AMS, and it is identified through the transmission of a signal from the responder on the animal to the antenna in the milking box. If the animal is not deemed ready for milking, the front or side gate will open automatically, allowing it to exit. If the animal is ready to be milked, the milking process will proceed. In AMS, milking times can be divided into two phases:  Handling time: this refers to the total time required for the animal to enter and exit the milking box, the movements of the robotic arm, the cleaning of the teats before attaching the teat cups, the attachment of the teat cups, and the post-milking disinfection of the teats. During this phase, the robotic station is engaged, but no milking occurs,  Machine on time: this refers to the actual milking time and is influenced by milk flow. It usually starts shortly after the teat cups are attached and ends when the last teat cup is removed. 2. Concentrate Distribution: one or more concentrates, stored in silos, are administered to the animal based on its specific needs (considering lactation stage and production level). 3. Teat Detection: the reliability and speed of the AMS depend on the vision system employed, which must ensure high precision due to the considerable variability in teat size and position, as well as udder shape across different stages of lactation. The most common technologies used are laser beams or cameras. 4. Teat Cleaning: after detecting the teats, they are cleaned and disinfected. Typically, water is used for washing, but some AMS systems also employ detergents. The cleaning process is carried out carefully, ensuring excellent stimulation, which leads to adequate oxytocin release. The water used for washing, along with disinfectant residues, is drained away. 5. Attachment and detachment of the Milking Unit: once cleaning is completed, the robotic arm attaches the teat cups. These may be stored in a container and attached one by one (independent system), or a milking cluster may be used (grouped teat cups), which is currently the most common solution. In modern AMS models, quarter-based milking occurs without the use of a collector, ensuring individual teat detachment and eliminating issues related to over or under milking. Automated milking allows animals to adequate the number of milkings based on their production. Thus, more productive animals visit the AMS more frequently than less productive or animals in late-lactation. 6. Post-Dipping Application: after milking, the AMS applies a post-dipping disinfectant that acts as an antibacterial agent. The disinfectant can be applied either internally via the teat cups or sprayed directly onto the teats using an external applicator positioned on the robotic arm. 7. Disinfection of the milking unit and animal exit: finally, the teat cups undergo a washing process to ensure optimal disinfection of the entire milking unit, preventing the transmission of pathogenic bacteria from one animal to another. - Insegnamenti PLF
