Milking Philosophy - a product of decades of experience in
research and improvement

Our milking philosophy is part of your success: Healthy livestock – high milk yield – safe quality. 
Pursuing the objective to adapt mechanised milk production to the model of nature, IMPULSA has developed a high-quality milking system over many decades which is protected by numerous patents.
Our milking and cooling system will convince you through the great variety of variants, technical perfection and individual adaptation to the requirements tied to medium-sized and larger livestock.

The IMPULSA milking philosophy is market through:

  • Udder Preparation
  • Udder Stimulation
  • Milking in Conformity with the Standards
  • Stripping and Udder Health
  • Udder Health Monitoring and Intermediate Cluster Disinfection

Udder Preparation

The process of milking begins with the preparation of the udder. This does not only serve for the fulfilment of milk-hygienic requirements, but it also constitutes an essential part of udder stimulation and, furthermore, initiates the milk ejection reflex. By milking off 2 to 3 milk streams from each teat, the germ-enriched first milk is secreted. By recognising changes in the milk, an udder disease can be noticed in due time. Through udder cleaning it must be ensured that no dirt can enter the milk.

Udder Stimulation

It is a proven fact that between the beginning of udder stimulation and engorging of the milk an average period of 60 seconds will pass. This is the so-called latent period of the milk ejection reflex. The milk ejection reflex can be triggered by way of different types of manipulation. Effective are milking-off of the first milk streams, udder cleaning and additional udder massage. As a result of udder stimulation, the oxytocin hormone which is essential for reaching the readiness for milking as well as other hormones are re-leased. However, udder preparation and the stimuli triggered by the pulsating teat liners alone are not enough in order to achieve quick and complete udder emptying.
Insufficient stimulation will lead to milk yield losses of up to 10%. In order to automate the stimulation deficit, IMPULSA has pursued intensive research work and, as a result, developed compressed-air stimulation and the APF process (alternating pulsation frequency increase) with pre-stimulation. APF pulsation is effective over the entire main milking time and ensures an increased oxytocin level and, consequentially, quick sucking off even in case of a high milk stream. In the course of this process, after each 10 seconds of standard pulsation the pulsation frequency has increased to 200 cycles/min for each 5 seconds.

Milking in Conformity with the Standards

Stable vacuum conditions are a decisive precondition for quality-responsive milking in conformity with the standards. Consequentially, the right choice of the vacuum installation in dependence of pipeline length, pipeline arrangement and the number of milking stands is of great importance. Apart from a stable milking vacuum on the teat, the optimal implementation of the pulsation parameters is a decisive aspect for gentle, quick and complete milking. Electronically controlled pulsators ensure an exact and stable pulsation. In connection with electronic milk stream sensors and/or the milk meter, the pulsation regime can automatically be adapted to the milking behavior of the cow (quickly- and slowly-milked cows). At the same time, these devices monitor the milking process and transmit the signal for the right point in time for switching on the strip-ping facility and for switching off the milking machine as well as for automatic cluster removal. In this way, harmful blind milking is excluded. The cluster is the junction point between milking machine and animal. In order to ensure that the stable milking vacuum in the milk pipeline is still stable on the teat, the milk ways within the cluster must be dimensioned and designed in a way that flow losses which can result in milk stream-dependent vacuum fluctuations are minimised. The clawpiece must ensure a quick passage of the milk without any turbulence and reflux into the milking cups. A volume of 150 to 250 cm³ and an air supply of 8 to 10l/min above the milk inlets meet these requirements in an ideal manner. Features of a good teat liner are a soft shaft, soft lips and a stiff head. With teat liners in divided or monobloc design with nominal widths of 23 and 25 mm, the adaptation to any livestock is ensured. The long milk hose with 14 and 16 mm in diameter, depending on the pipeline arrangement, is ideally dimensioned in terms of fluid technics. By means of milking cup shells of different weight, the cluster can be optimised in accor-dance with the respective animal and type of milking installation.

Stripping and Udder Health

Suction milking machines are not able to milk out all cows completely. Due to the underlying principle a contraction occurs between teat cisterns and udder cisterns shortly before the end of milking which results in an iris-like choking within the pulsation rhythm and impedes the complete sucking-off of the milk. The stripping quantity is between an average of 300 and 500 g. Since the extraction of the strippings is very intensive in terms of manual work, IMPULSA has developed a patented stripping and removal unit. The IMPULSA stripping facility, where the cluster is pulled down rhythmically with the help of the take-off rope going over a deflection roller on the floor, implements the draining-off of the residual milk from the udder. The same results are achieved with the IMPULSA ProfiMelkarm. It makes eases the work significantly. The degree of emptying is just as good as that achieved manually by the milker.

Udder Health Monitoring and Intermediate Cluster Disinfection

High milk yields and a good milk quality can only be achieved with healthy udders. Continuous monitoring of the udders is abso-lutely necessary for the early detection of udder diseases. Scanning the emptied udders at the end of milking provides reliable information. Teat dipping is a proven, effective method in order to prevent morbific agents from entering the expanded streak canal. Disinfecting the milking cups after each milking process is also a suitable means in order to ensure udder health. With IMPULSA parlour installations the intermediate cluster disinfection is integrated in the milking program offering two technical solutions, either in the form of a “bucket variant” or of a “pulling-through variant” for rotary milking parlours.Manual pistol lances and air wash systems supplement the program.
