Definitions

  • the fatty acid has a chain length C18 and more preferably the fatty acid is linolenic acid.
  • the composition includes stabilising amounts of surfactants to enable a stable oil-in-water emulsion to be formed.
  • the surfactants include a non-ionic surfactant, in particular a polyethylene oxide derivative.
  • the surfactants are substantially non-ionic.
  • suitable surfactants are sorbitan onolaurate and ethoxylates thereof.
  • Surfactants are selected on the basis of their ability to form stable oil-in-water emulsions. Generally it is best if at least two surfactants are used, one with a HLB value less than 10 and one with a HLB value i .excess of 10. It is important that the surfactants when used in the teat dip composition do not result in unacceptable residues in milk.
  • the surfactants are used at art recognised levels and are typically of the order 1-20% by weight of oil phase. It is believed the surfactants also inhibit the adhesion of mastitis pathogens thereby improving the efficacy of the composition.
  • the unsaturated fatty acid is effective in killing the Staphylococus aureus and Streptococci (gram positive bacteria) believed to contribute to mastitis disease control by post milking hygiene.
  • Other bacteria particularly gram negative bacteria are relatively unaffected.
  • some bacterial resistance remains from the unkilled bacteria.
  • harmless bacteria remain as a protective coating on the teats.
  • the compositions of the present invention provides some residual bacterial protection between milkings.
  • Span 60 is added to the hydrolysed linseed oil, heated and stirred until the Span 60 is dissolved, the Tween 20 is then added to this solution, after which this mixture is added to an equal volume of deionised water and agitated. An emulsion formed which was then diluted with more deionised water to lead to 93 parts of water in the overall composition. The resulting teat dip composition was stable over a period of several weeks with no evidence of the emulsion breaking. The composition was evaluated in vitro by appropriate cell counts of S-aureus bacteria. As controls water, chlorine and an iodine based commercial treatments were used. Generally the results showed the composition to be more effective in killing the bacteria than either of the commercial control materials.
  • Streptococcus aqalactiae were much more sensitive to the active ingredient and Example 1 than the strains of Staphylococcus aureus.
  • a teat dip should prove effective in reducing the recoverable number of bacteria (mastitis pathogens) which have been experimentally applied to the teat.
  • a mastitis pathogen Staphylococcus aureus
  • Example 1 The composition of Example 1 was tested at the Gilbert Chandler Institute of Dairy Technology, Werribee, for its effect on cheese starter and yoghurt making bacteria. The effect of test compounds on these bacteria is measured in terms of the change in pH during the cheese yoghurt making. If the cheese containing a test compound, at a given concentration, has a pH at the end of the incubation > 0.2 units higher than the control batch then the test compound had a significant effect at that concentration. It was found with the composition of Example 1 that at concentrations ⁇ 1 ul/ml of milk there was no significant effect on cheese or yoghurt making. This concentration (1 ul composition of
  • Example 1/ml of milk represents a dilution of 1 :1000.
  • 20 ml of composition of Example 1 would be required to significantly affect cheese and yoghurt making.
  • Example 1 When the composition of Example 1 was tested on the two herds for its effect on teat skin, swabs were also taken of the teats that had been treated twice daily with either the composition of Example 1 , iodine (5000 ppm) or untreated for 8 weeks. At the end of the experiment swabs of all teats were taken 14 hours after treatment and serial dilutions of fluid from them were plated onto staphylococcal selective medium (sheep blood agar).
  • staphylococcal selective medium staphylococcal selective medium
  • Swabs from the composition of Example 1 treated teats when compared to iodine—treated teats have:
  • Swabs from the composition of Example 1 treated teats when compared with untreated teats have:
  • Example 1 The composition of Example 1 is more effective than iodine in holding staphylococcal numbers down between milkings.
  • Example 1 The composition of Example 1 promotes the survival of bacilli (and possibly other less pathogenic bacteria on teats which may lead to reduced reinfection of the teat through competition.

Abstract

La composition pour bain pour trayon décrite est destinée à être utilisée dans le traitement de la mastite chez les vaches laitières. Sous sa forme prête pour l'application, cette composition se présente comme une émulsion d'huile dans l'eau. La phase d'huile contient un acide gras non saturé, constitué par exemple par un acide gras d'huile de lin, dont la longueur de la chaîne de carbones est comprise entre 16 et 20.
