Lely T4C 3.7 update - treatment plans and rumination

With the latest Lely T4C update several functionalities have been changed. Among other things, treatment plans and the rumination KPI have been optimized. In this article we discuss the details in greater depth.

Lely T4C 3.7 - treatment plans

Whether a farm has one, four or sixteen milking robots, working according to standard operating procedures (SOP) or protocols is important and is becoming more and more the norm. Working according to protocols reduces the risk of forgotten steps and increases peace of mind. While developing Lely T4C we keep this continuously in mind, for example with the improved treatment plans. Here, the next step of working according to protocols in combination with Lely T4C is achieved.

How does it work?

Within Lely T4C 3.7 treatment plans, we now offer the possibility of using irregular treatment intervals, multiple medicines and actions such as ‘Insemination’. When a treatment plan is applied to a cow on ‘Report 14 – Health Treatment task’, you can see the tasks that need to be done today. In addition, it becomes possible to apply an OvSync strategy as a pre-planned multi-step treatment. In addition to this, the default disease list in T4C has been updated according to ICAR standards. Now it also covers, for example, vaccinations and fertility treatments. 


What do we gain?

•    The farmer, Farm Management Advisor and veterinarian can make treatment plans that fit the farmer’s needs based on local circumstances.
•    It is possible to use treatment plans with multiple medicines, such as a dry-off treatment including a teat sealant.
•    Easier and more user-friendly application of treatment plans and a reduced change of forgotten steps, thus increasing their use.
•    Farmers have an overview of health treatments to be performed today.

Lely T4C 3.7 – rumination activity

Rumination is a reliable indicator of cows’ well-being. Too much or too little rumination indicates that something is going on, meaning action is required. The rumination activity KPI on the Lely T4C dashboard alerts farmers to sick cows and herd-level changes and provides additional certainty for cows in heat. Starting with the T4C 3.7 update we are focusing more on changes to rumination activity compared to previous fixed levels. This results in even more focus on changes in rumination activity and more uniformity on the T4C dashboard.

The rumination KPI

The colored areas of the ‘Rumination activity’ KPI now depend on the average rumination on the farm (except for QWES HR tags). If the KPI is in the orange areas (+ or – 10% deviation) or in the red areas (+ or – 15% deviation), it shows a significant deviation from the normal rumination and it is advised to investigate and take action(s).


Rumination trend watching
•    Focus and act on changes: check Report 20 ‘Milk production in time’ to have a closer look at the trend. Or open Report 24 ‘Health activity/rumination’ to see which cows are causing the disturbance.
•    Consistency: if rumination activity from day to day varies a lot, it is advised to look at what is causing this. What is different on the days with high rumination? Think of a different feeding protocol or a disturbance to the cows.

A cow with low rumination activity (Report 24 ‘Health activity/rumination’) is a risk in combination with:
•    fat and protein levels;
•    reduced milk yield;
•    concentrate intake.

What do we gain?

With this method of monitoring, a better focus on changes to rumination activity on the farm becomes possible.

Lely T4C 3.7 – general updates

Report 10 – Health Attentions

In Report 10 ‘Health attentions’, a new parameter has been introduced: ‘Fresh Cow Performance’. This compares the milk production of a cow to the group average with the same days in lactation. When the milk production of the cow is too low compared to the group, an attention is raised for this in Report 10 ‘Health attentions’. This parameter only affects the first 21 days of lactation and is a valuable addition for finding cows with ketosis or metritis. 


Merging of Reports 13 and 14

Report 13 ‘Failed milkings’ is the new report for failed milkings. Within the settings of the report you can select whether you want to see by default all failed milkings, or only failed milkings for which the cow did not have a successful milking afterwards, using the option: ‘Only show current failed milkings’.


Lely T4C Vector - easier manual registration of number of cows in a group and weight of the animals

For Lely T4C Vector it is possible to insert the number of cows in a location manually. With the latest version of T4C this has become easier. You can also insert the average weight in the case of beef cattle. In ‘Report 78 – Feeding – Beef Intake’, this weight will then be shown on the graph.
