Artificial Vagina
Introduction
- Simulates the vaginal conditions of a female in oestrus.
- Generally consist of
- Outer casing of reinforced rubber
- Rubber liner that can be lubricated
- Temperature and pressure are controlled by water placed between the casing and liner.
- One end is attached to a funnel-like cone that is attached to a collection vessel, usually a non-breakable test tube.
- The desgin of the artificial vagina should accomplish the following:
- Provide a suitable environment for stimulation of the glans penis.
- Provide an environment that prevents damage to the penis.
- Provide an environment that maximizes sperm recovery and minimizes sperm insult.
Advantages and Disadvantages of Using a Surrogate Stimulus
- Males need training to mount a surrogate animal or 'dummy'.
- Advantages of a surrogate animal:
- Ease of cleaning
- Minimizes risk of injury
- Minimizes risk of disease transmission
- Surrogate animals do not require feed input, housing or labour for maintenance.
- Size can be easily adjusted to accommodate various males.
- Can be mobile, so location can be changed with ease. This avoids changing location of the male - which is more dangerous, especially with Bulls.
- Disadvantages of a surrogate animal:
- Changing the location of teasers is difficult.
- Requires previous training of the male
Species Differences
- Stallion:
- Leather outer casing equiped with a port to drain water.
- Collection vessel and protective covering
- Ideally, ejaculation takes place in a collection cone so that most semen drains directly into the collection vessel.
- Surrogate stimulus used to collect semen from the Stallion is referred to as a 'phantom'.
- Phantom has a biting belt to provide the stallion with a surface to bite during mounting thus providing a means for natural behaviour.
- Bull:
- Black casing
- Rubber liner
- Collection cone and collection vessel
- Water is placed between the casing and the liner.
- Proper temperature critical for successful ejaculation.
- Protective covering placed over the cone and collection vessel to prevent cold shock of the semen.
- Boar:
- Bulb that can apply pressure to the artificial vagina.
- High pressure is obligatory for stimulation of the glans penis and ejaculation in the boar.
- Outer casing and liner
- Protective covering that houses the collection vessel.
- Bulb that can apply pressure to the artificial vagina.
- Ram and Buck:
- Rubber casing with a valve through which water can be added or emptied.
- Rubber liner and collection vessel.
- Protective covering
