New Zealand farming. Electric power fencing – Glossary of terms.


Dr Clive Dalton

Amp: Unit of current.  Watts divided by voltage.

Current: It is current and the duration and rat of its low which causes a shock.  Increasing voltage increases current.  Current decreases as resistance increases.

Capacitance: Ability to store a charge of electricity.

Capacitor:  Stores electrical chares and ule as energy which builds up in the capacitor and is released by the SCR switch into the fence at approximately one per second.

Electrolysis:  Corrosion which occurs when different metals are connected in a wet environment such as with electrical connections on a fence line.

Impedance: Combination of resistance, induction, frequency and capacitance (sometimes called AC resistance).

Induction: Power transfer without contact.  For example – charging of dead or neutral fence wires which run parallel to live ones.

Insulator: A material across which current will not flow.

Joule:  Unit of energy. Watts x seconds.  Measures the ‘kick’ of a fence pulse.

Leakage: Loss of power conducted from the fence to the ground, caused by poor insulators, shorts and herbage growth on the wires.

Measurement: 500 ohms (2mS) which is the maximum a human or animal can conduct in the worst conditions e.g. with feet and hands in salt water.  5000 ohms (0.2mS) is the equivalent of a cow touching an electric wire.  ( See Siemens).

Ohm:  Unit of resistance.  The ohm scale is a reverse one – so low numbers indicate heavy load and high numbers indicate a light load.

Outrigger: Electrified wire attached to conventional fence, supported in a way to keep stock from contacting the fence.

Power consumption: Electricity consumption does not increase with leakageon the fence because most energisers operate on maximum all the time and the VDR’s absorb the unused surplus.

SCR:  Silicon Controlled Rectifier which is a transistorised pulse switch.

Siemens:  Unit of conductance, leakage or load.  Reciprocal of ohm.  1 Siemens = 1 ohm, 1 millisiemens (mS) + 1000 ohms.

VDR:  Voltage dependent resistor. Prevents voltage of more than 5000 volts from leaving the power unit by short circuiting the excess voltage.

Volt:  Unit of electrical pressure which causes current to flow. Voltage = current x resistance.

Watt:  Unit of power – both electrical and mechanical.  746 watts = 1 Horse power.

New Zealand farming. Deer - Glossary of terms

 
Dr Clive Dalton



Farmed Red deer hinds

Deer in New Zealand
All deer were introduced into New Zealand in the late 1800s by the early European pioneers for sport, after which they multiplied to become classed as noxious pests due to the damage they did to native bush and were then subject to government culling programmes.  Later in the 1960s deer were successfully farmed (see * in list) for the export of venison, velvet and other body parts.

Breeds
*Red
*Fallow
*Wapiti
*Rusa
Virginian (white tail)
Japanese Sika
Sambar
Himalayan Thar
Chamois

Antlers:  Distinct from the permanent horns of sheep, cattle and goats which grow on bone structures which are part of the skull.  Antlers grow anew each year from pedicles which are permanent growths on the frontal bones of the skull. They are shed in September/October (early spring) each year and new growth starts almost immediately.

Bugle:  The  sound made by male Wapiti during the mating season to attract females and to challenge other males.

Coronet: Ring or burr around the base of antlers.

Doe: Mature female used for breeds other than Red deer and sometimes Wapiti.

Havier:  Castrated male deer.

Hind: Mature female Red deer and sometimes Wapiti.

Hummel:  Castrated male deer.

Male deer:
Buck: male Fallow deer.
Bull:  male Wapiti
Stag: male Red deer
Spiker: juvenile male with two spikes which will eventually grow into full antlers.

Juveniles:
Calf:  Red deer and Wapiti.
Fawn: Fallow deer, but also used for other breeds.

Mane: Increased growth of hair on the enlarged neck of male Wapiti and Red deer during the rut.

Palmation: By about their third or fourth season fallow deer develop a distinctive flattening or palmation at the end of their antlers. The edges of the palms are marked by a series of points called spillers or snags.

Pearling: Knobbly or ridged texture or the antlers on some species of deer.

Pedicle: The first part of antler grown on a deer’s head from which the antlers grow.  Often called the button.

Pelage: The coat of deer.

Roar:  The sound made by male deer of some species during the mating season to attract females and challenge other males.  The mating season is sometimes referred to as ‘the roar’.

Rut:  The mating season when males start to attract females and challenge other males.

Slink: Deer calf or fawn in utero valued for its skin.

Snags:  See palmation.

Spillers:  See palmation

Spottie:  Young deer (usually fallow) up to three months old when it still shows the spotted coat pattern.

Young Fallow deer showing spotted coats

Tine:  The points or branches off the main ‘beam’ of antlers.  The number increases each year with age and are given names e.g. brow, bray, tray.

Velvet:  Early vascular growth of antlers before they harden off. Characterised by soft velvet coating which dies and is rubbed off by deer as antlers mature and harden.  Deer are very protective of their antlers when in velvet and avoid challenges among males.

Sheep Farm Husbandry - Glossary

Extensive glossary of technical and commonly used farming terms concerned with sheep farming, shearing and wool preparation, and preparation of sheep skins.

By Dr Clive Dalton



SHEEP
  • Alpha lambs: Unweaned lambs too heavy for the beta trade, and up to 18-20kg live weight. They are not tail-docked or castrated.
  • Beta or bobby lamb: Milk fed lamb fed on the ewe from 1 to 3 weeks of age, going for slaughter at around 14kg live weight. They are not usually tail-docked or castrated.
  • Cast-for-age (CFA): Old ewes culled from the flock because of age; usually over 5 years old.
  • Cast sheep: Sheep found lying on its back unable to get up, usually because it is heavy in lamb or has a heavy fleece.
  • Cryptorchid: There are two meanings. A true cryptorchid is a male with undescended testicle or testicles, but the term is also used to describe a lamb that has been made infertile (ie castrated) by applying a rubber ring below the testicles to remove the scrotum, leaving the testes pushed up against the body (see Castration below).

  • Ewe: Mature female sheep, usually over two years old.
  • Fecundity: Ability to produce and rear offspring.
  • Fertility: Ability to produce fertile eggs (ova) in the ewe and viable semen in the ram.

  • Lamb: Young sheep between birth and weaning (up to about 3 to 4 months old). Note: the meat industry uses the term “lamb” for sheep that have not yet got their first pair of permanent incisors, i.e. up to a year old or a little older.
  • Long tailer: Male with tail left undocked to indicate that it was not castrated.
  • Perinatal lamb mortality: Lambs that die within three days of birth.
  • Ram: Male sheep of any age.
