Test report 7418

The approval

A test mark „DLG-APPROVED for individual criteria“ is awarded for agricultural products which have success­fully fulfilled a scope-reduced usability testing conducted by DLG according to independent and recognised evaluation criteria. The test is intended to highlight particular innovations and key criteria of the test object. The test may contain criteria from the DLG test scope for overall tests, or focus on other value-determining characteristics and properties of the test subject. The minimum requirements, test conditions and procedures as well as the evaluation bases of the test results will be specified in consultation with an expert group of DLG. They corres­pond to the recognised rules of technology, as well as scientific and agricultural knowledge and requirements. The successful testing is concluded with the publication of a test report, as well as the awarding of the test mark which is valid for five years from the date of awarding. 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 23th October 2013, Annex 6) and DIN 3763:2022-08 (Elastic floorings for cattle and dairy cows walking and rest surfaces – Requirements and testing). Other criteria were not tested.

Assessment – brief summary

The Animattress I tested here has been tested in the DLG-Approved Single Criteria Test “BTS cattle“ tested on test rigs for comfort properties.
In three farms, joint evaluations and behavioral observations when getting up and lying down are carried out.

Requierements of the BTS Programme Regarding Deformable Mattresses for Bovine Livestock” (Swiss Ethics Programme Ordinance of 23 October 2013, Annex 6) are fulfilled.

Deformability and elasticity: Class 4 according to DIN 3763.

The product

Description and Technical Data

The Animattress I cubicle mattress tested here is an elastic floor covering for use in the resting area of high cubicles in cubicle houses

  • Thickness approx. 53 mm
  • Top cover
    • black rubber mat
    • upper side with silkscreen structure
    • under side with white woven textile
    • thickness approx. 4.5 mm
  • Shore A hardness: approx. 75
  • Mattress underlay 
    made of approx. 48 mm thick PU foam sheet which is covered  with an colourless film (thickness approx. 1 mm)
  • Laid as sheeting

The method

Deformability and elasticity

The deformability is measured in new condition and following permanent tread load using ball penetration tests with a calotte (r = 120 mm) and a penetration force of 2,000 N (corresponding to approx. 200 kg).

Permanent tread load 

The permanent tread load is measured on a test stand with a round steel foot in the standard test programme 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. 

Animal health

On at least 3 farms, the tarsi (ankle joints) of all cows2 by an independent, experienced specialist were examined and the behaviour of the animals when they get up and lay down on the flooring was observed.

In all lying boxes at least 3 months before the examination mats of the product to be tested were installed. The cows to be examined are at least 3 months before the examination kept exclusively in the barn concerned, i.e. they have no grazing.

Exceptions: Cows in the first third of lactation / considered cows / cows that were placed for less than 3 months before the examination have been kept in the barn in question (e.g. purchased ones; see also 2.4) / Cows that are lying in the walkway / Cows that are sick are or have recently been (e.g. stuck after calving) / cows that are injured due to accidents.

The test results in detail

Animal health

On 3 farms became the Tarsi (ankle joints) of 156 cows by an independent, experienced spe­cialist in this regard examined and the behavior of the animals when getting up and lying down on the flooring.

The requirements regarding BTS compliance is met

Deformability and elasticity

In the ball penetration tests in new condition with a calotte (r = 120 mm), penetration depth was 25.7 mm. The resulting calculated bearing ­pressure of 10.3 N/cm² indicates a low load on the carpal joints when lying down and getting up.

Elasticity was measured following a permanent tread load exerted by 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 25.7 mm to 27.7 mm. The bearing pressure decreased from 10.3 N/cm² to 9.6 N/cm² (see Figure 3). This means that deformability and elasticity slightly increase.

The requirements regarding BTS compliance is met

Permanent tread load 

Slight wear was observed on the top cover following exposure to permanent tread load on a test stand with 100,000 alternating loads at 10,000 N. No lasting deformation was observed.
