Definitions

  • the present invention relates to preparations for the treatment of the udder of a lactating mammal, suitable for reducing the number of pathogenic germs on the udder, on the teat and within the teat canal.
  • the preparation for treatment of an udder serves to prevent udder infections, more preferably is suitable for the treatment of an udder to support the treatment of infections of the udder and/or teat.
  • the present invention can be used for the treatment of various animals, as e.g,. for the treatment of sheep, goats, buffalo, camels, dromedary, yaks, horses, donkeys and other lactating animals.
  • the invention can be used in conjunction with milking stalls with conventional milking systems, with mechanical milking systems and with semi-automated milking systems. It can also be used in connection with systems, where a semi-automated, fully automated or robotic system is used to prepare and/or to clean of the teats of the animals. It can also be used in systems with a semi-automated or full automated attaching device of the milking cups to the teats of the animals.
  • milky mammals e.g. cattle, sheep and goats are nowadays milked by automatic milking techniques.
  • the long-term breeding successes tuning the animals to a high milk productivity has led to a high susceptibility for infections of mammary glands, udder and teat.
  • This susceptibility for infections is even raised by the strain put on the teats during milking as well as by environmental factors like wind, rain and sun continuously affecting the teats.
  • somatic cells within the milk As a result of the continuous strain on the teats the animals often suffer from infections of the udder, described in literature as subclinical or clinical mastitis. Depending on the level of infection of diseased udder sections, a slight up to a drastic increase of somatic cells within the milk is observed. The increase of somatic cells within the milk over the level of a healthy udder (200,000 cells per mL) is undesirable as the quality of the milk is limited for further processing steps, and, in the extreme, the milk undrinkable. A drastic increase of somatic cells within the milk is often accompanied by fever (clinical mastitis), which may even result in the loss of the animal.
  • a cause for such infections is the immigration of germs pathogenic to the udder like Pseudomonas aeruginosa, Escherichia coli, Streptococcus uberis, Streptococcus dysagalactiae, Streptococcus agalactiae, Streptococcus aureus or Enterococcus hirae.
  • the risk for an infection of the udder is greatest immediately after the milking procedure. During this time, the teat canal is open and accessible, allowing environmental germs to immigrate into the teat canal and cause infections.
  • a preparation for the treatment of udders and for the disinfection of dairy cattle, which is used as an aqueous emulsion having increased viscosity, is known to contain 800 to 10.000 ppm iodine in the form of a disinfection iodine complex as the active agent.
  • the disinfection iodine complexes are described as polyglycolether or polyvinylpyrrolidone adducts of iodine.
  • disinfection agents for teats contain a film-forming compound, namely polyvinylalcohol, a polymeric thickener as well as an antimicrobial non-ionic iodine complex.
  • a film-forming compound namely polyvinylalcohol
  • a polymeric thickener as well as an antimicrobial non-ionic iodine complex.
  • non-ionic iodine complex adducts of iodine to polyethyleneglycol, polypropyleneglycol or their copolymers are mentioned.
  • EP-A-I 312 371 proposes to use bacteria of the genus Brachybacterium as an antimicrobial agent.
  • these bacteria Depending on weather conditions, these bacteria have a limited effect as they are viable on the surface of teats only to a limited extent. Especially under very dry, very hot or very cold environmental conditions, bacteria of the genus Brachybacterium quickly die, necessitating a renewed application of the dip preparation for the udder containing these bacteria.
  • the present invention seeks to overcome the disadvantages of preparations and procedures for the treatment of udders and/or teats of lactating mammals, especially of dairy cattle, present in the state of art preparations.
  • the present invention seeks to provide a preparation suitable for the treatment of infections of the udder, teat and/or mammary glands of lactating mammals, which is characterized by a high stability, i.e. long resident time on the udder, teat and/or mammary gland, so that it preferably needs to be applied at most once a day, more preferably at most every two days arid most preferably at most only once a week or at even longer intervals.
  • a further problem to the invention is to provide a process for reducing, preferably inhibiting or preventing the growth of pathogenic bacteria on lactating mammals, which in comparison to known processes is preferably less complex and requires less expenditure, while concurrently having no or at least only little impact on the quality of milk.
  • the present invention solves the above-mentioned problems by providing a preparation for the treatment of the udder and/or teat of a lactating mammal, which preparation contains nonpathogenic, sporulating bacteria.
  • the present invention solves the above-mentioned problems also by providing a procedure for applying a preparation for the treatment of the udder and/or teat of a lactating mammal, which preparation contains at least partly non-pathogenic, sporulating bacteria.
  • the preparation may be an aqueous suspension of the non-pathogenic sporulating bacteria, an oil-in-water emulsion or a water-in-oil emulsion, containing a skin care agent.
  • the preparation may contain thickening agents like PEG, PPG, polyvinylpyrrolidone and further agents known from cosmetics, as well as emulgators, colorants, detergents and/or antimicrobial agents like iodine complexes.
  • pathogenicity of a bacterium is its property to be able to cause disease symptoms in a lactating mammal, especially in dairy cattle. Accordingly, a non-pathogenic bacterium within the terms of the present invention is a bacterium which does not cause disease symptoms in a lactating mammal, preferably in dairy cattle.
  • sporulating bacteria are defined as bacteria which are capable of transformation from their vegetative form into a non- vegetative dormant form, resistant to have environmental conditions like heat, cold and dryness. This non-vegetative stage, also termed spore, can germinate to the vegetative bacteria, able to replicate.
  • the preparation suitable for use on the udder and/or teat of a lactating mammal comprises at least 1 x 10 6 , preferably at least 1 x 10 7 , preferred at least 10 x 10 8 , more preferred at least 1 x 10 9 , most preferably, at least 1 x 10 10 non-pathogenic sporulating bacteria and/or spores of these bacteria per g or per mL of the preparation.
  • the preparation should comprise the number of bacteria as a sum of bacterial cells and non- vegetative spores.
  • the preparation is based on at least 25%, preferably at least 50%, more preferably at least 75% of bacteria in the state of spores, most preferably essentially of spores only, in relation to the sum of vegetative and non-vegetative bacteria.
  • the use of bacteria comprised in the preparations for the treatment of and udder and/or teat of a lactating mammal according to the invention is suitable to cause a long term reduction in the number of pathogenic bacteria because the competition for nutrients on the area treated with the preparation is tipped in favour of the non-pathogenic bacteria contained in the udder treatment composition according to the invention.
  • the bacteria used in the practice of the invention are assumed to consume putative nutrients for pathogenic bacteria, minimizing, preferably eliminating, nutrients available to pathogenic germs.
