Barn hygiene in general leads to healthy cows. Optimal hygiene in calf feeding results in healthy growth of calves into mature dairy cows delivering high-quality milk in the tank during their complete lifespan.

Excellent hygiene is one of the benefits of automated calf feeding with a Lely Calm. It’s the combination of 3 elements that does the trick: the HygieneBox, the YelloTeat, and sequence cleansing.


The HygieneBox is the connection between the calf and the Lely Calm. It guarantees optimal hygiene down to the teat through a thorough and fully automated cleaning process in 2 steps.

The first step takes place immediately after a calf has drunk: the teat is being cleaned with fresh water from the inside and the outside.

The second phase is the cleaning of the inside of the system in several steps. Firstly, pre-rinsing with water. Then the full internal system and all milk-carrying elements are thoroughly cleaned with a detergent finalized with another rinsing with fresh water. This can be done even up to 4 times a day without any extra work for you.

A fully automated and thorough process for excellent hygiene down the teat and safeguarding the milk quality for your calves.



In addition to the HygieneBox and the automated cleaning process, the Lely Calm is equipped with the so-called YelloTeat. The teat of the drinking box is made of a hygienic material that is highly dirt repellent. An extra way to reach excellent hygiene.


Sequence cleansing with Lely Consumables

To guarantee maximum hygiene, the Lely Calm can be cleaned with 2 specific detergents: Lely Calm Cid and Lely Calm Lin. Both detergents are developed for the Lely Calm specifically.

Lely Calm Cid is an acid product that removes scale, lime, iron and milkstone residues. The alkaline non-chlorinated Lely Calm Lin effectively removes fat, protein and sugar residues from the milk. 

The combination of both detergents and interval cleaning brings excellent hygiene of the full inside of the Lely Calm.
