Animattress/Animatelas III cubicle mattress
The Animattress III tested here, an elastic floor covering for the resting area in cubicle houses, was investigated with regard to comfort characteristics on test rigs in the DLG Appoved Test “BTS Cattle1” (Swiss support programme for especially animal-friendly housing systems ). Joint inspections were carried out in three real-life farms, and behavioural observations were made during standing up and lying down. The requirements of the BTS programme regarding deformable mattresses for bovine livestock (Swiss Ethics Programme Ordinance of 25th June 2008, Annex 3) are met.
Animattress/Animatelas III cubicle mattress
The Animattress III cubicle mattress tested here is an elastic floor covering for use in the resting area
of high cubicles in cubicle houses; it has a thickness of approx. 32 mm.
The deformability is measured using ball-indentation tests in new condition and following permanent tread load with a calotte (r = 120 mm) and a penetration force of 2,000 N (corresponding to approx. 200 kg).
The permanent tread load is measured on a test rig with a round steel foot with 100,000 alternating loads at 10,000 N (corresponding to approx. 1,000 kg). The steel foot is adapted to the natural conditions as an “artificial cow foot”. The foot has a diameter of 105 mm and therefore a contact area of 75 cm²; the carrying edge of the hoof is simulated by a 5 mm wide ring on the periphery of the sole that projects 1 mm above the rest of the surface.
At a minimum of three farms, the tarsi (ankle joints) of all1 cows held in the relevant cowsheds are examined by an independent specialist with relevant experience, and the animals’ behaviour while standing up and lying down on the floor covering is observed. Mats of the make to be tested are installed in all cubicles at least three months before examination. The examined cows are held exclusively in the relevant cowshed for at least three months before the examination; i.e. they have no access to grazing.
1 Exceptions: cows in the first trimester of lactation / non-lactating cows / cows that were held in the relevant cowshed for less than three months prior to examination (e.g. purchased; see 2.4) / cows that often lie in the walkway / cows that are ill or were ill recently (e.g. recumbency after calving) / cows injured due to an accident
At three farms, the tarsi (ankle joints) of 118 cows were examined by an independent specialist with relevant experience, and the animals’ behaviour while standing up and lying down on the floor covering was observed. The requirements relating to BTS conformity are met.
A penetration depth of 10.1 mm was determined in ball-indentation tests in new condition with a calotte (r = 120 mm) and a penetration force of 2,000 N (corresponding to approx. 200 kg). A bearing pressure of 26.2 N/cm² was calculated from this, indicating a relatively small load on the carpal joints when lying down and standing up.
The elasticity was measured following a permanent loading test with a steel foot (contact area 75 cm²) with 100,000 alternating loads at 10,000 N. Following the endurance test, the penetration depth of the calotte increased from 10.1 mm to 10.7 mm. The bearing pressure decreased from 26.2 N/cm² to 24.8 N/cm² (see Figure 2).
This corresponds to a increase in deformability and elasticity. The requirements relating to BTS conformity are met.
No noticeable wear was observed following exposure to permanent tread load on a test stand with 100,000 alternating loads at 10,000 N. No lasting deformation was observed.

A quality mark “DLG-APPROVED for single value-determining criteria” is awarded to agricultural products which successfully passed a smaller-scope DLG usability test according to independent and recognized evaluation criteria. The test intends to highlight special innovations and key criteria of the test item. The test can focus on criteria from the DLG testing framework for full tests or on other individual features or qualitative criteria. The minimum requirements, the test conditions and procedures as well as the evaluation guidelines of the test results are determined in consultation with a DLG expert group. They comply with the generally recognized technology rules as well as with scientific and agricultural knowledge and requirements. The successful test concludes with the publishing of a test report and the awarding of a quality mark which is valid for five years following the award date.
The DLG Approved “BTS Cattle1” included joint inspections and behavioural observations during standing up and lying down in three working farms, as well as measurement of deformability on test rigs at the DLG Test Center Technology and Farm Inputs. Data was acquired and analysed in accordance with the “Requirements of the BTS Programme Regarding Deformable Mattresses for Bovine Livestock” (Swiss Ethics Programme Ordinance of 25th June 2008, Annex 3). Other criteria were not investigated.
