Definitions

  • This invention relates to a metering device for use in artificial insemination of animals, and in particular, but not exclusively, pigs.
  • the first container is a screw top bottle.
  • the outlet of the bottle is a snip-top nozzle for insertion to a catheter, which mimics the boar's penis, for insertion into a sow.
  • the second is similar to a plastic toothpaste tube.
  • a specific quantity of diluted semen is introduced into the tube, which is then sealed.
  • the other end of the tube is provided as a nozzle, which, as with the bottle, is provided as a snip-top for insertion into a catheter.
  • Each dose of diluted semen is usually between 70 and 100ml.
  • the other single dose container is known as a flat pack.
  • This is a form of bag, into which the semen is introduced. It is then heat sealed.
  • the flat pack is formed such that a catheter can be attached to the flat pack for introduction of the semen to the sow.
  • the flat pack is the most recent single dose container to be introduced onto the market.
  • the object of the present invention is to provide a metering device for metering diluted semen from a bulk container for insemination of a female.
  • a metering device for use in artificial insemination of an animal, comprising: a collapsible dispensing container having, or marked with, a predetermined volume when containing diluted semen added via an upper inlet for dispensing via a lower outlet; an obturatable feed tube adapted to be directly or indirectly connected to a bulk container of diluted semen and to be obturated on feeding of the predetermined volume of the diluted semen into the dispensing container via the inlet thereof; and an obturatable dispensing tube for dispensing the predetermined volume of the diluted semen from the container via the outlet thereof for presentation to the animal.
  • both these tubes will be obturatable by compression, typically in the form of a clamp.

Abstract

L'invention porte sur un dispositif de mesure (1; 100; 200) destinée à être utilisée dans l'insémination artificielle de semence animale. Ce dispositif comprend un réceptacle de distribution pliable (20; 120; 220) d'un volume prédéterminé, portant des graduations, et pouvant contenir du sperme dilué introduit par un orifice d'admission supérieur et distribué par un orifice d'évacuation inférieur. Un tube d'alimentation obturable (3; 103; 203) est conçu pour être raccordé directement ou indirectement à un réceptacle en vrac (9; 109) de sperme dilué et être obturé lors de l'introduction du volume prédéterminé de sperme dilué dans le réceptacle de distribution via son orifice d'admission. Un tube de distribution obturable (30; 130; 230) permet de distribuer le volume prédéterminé de sperme dilué du réceptacle via l'orifice d'évacuation qui sera présenté à l'animal. L'invention porte également sur un procédé d'utilisation de ce procédé.
