Tools for Breeding Management

• Castration tools are used to prevent male animals
  from breeding.
• What are some reasons that we would not want
  males to breed in animal production?

6
Reasons for Castration

• Farmers remove their calves' testicles to reduce
  aggressiveness in male animals as they mature.
• In the food industry, livestock are castrated in
  order to increase their weight and improve the
  taste of the meat

Tools for Breeding Management

• Burdizzo Clamp
• The burdizzo is used for a bloodless and
  relatively painless method of castration. It
  crushes the blood vessels and interrupts the
  blood supply.

9
Tools for Breeding Management

• Elastrator
• A tool that places bands around both testicles
  and cuts off blood supply. The scrotum falls off
  in 20-40 days.

10
Artificial Insemination (A.I) Tools

• Artificial Insemination is when sperm is placed
  into a female's uterus using artificial means
  rather than by natural copulation.

11
Artificial Insemination Tools

• For artificial insemination the sperm must be
  collected manually of through the use of an
  artificial vagina. These have a collection tube
  at the end so that the sperm can be easily
  collected.

Artificial Insemination Tools

• Insemination straws are used for the disposition
  of semen into the female.

Dehorning

• Why Dehorn Livestock?
• Horned livestock
• can cause severe injury to other animals people
• are harder to handle in yards
• require more space at a feed trough and on
  trucks.
• may suffer discounts at sale

15
Animal Management Tools

• A dehorner is used to remove horns from cattle.
• There are many different types

16
Types of Dehorners

• Barnes Dehorner
• Electric Hot Iron
• Rechargeable Electric Dehorner

Animal Management Tools

• A rectal thermometer is used to take the
  temperature of animals.

19
Animal Management Tools

• A syringe is used to give injections or draw body
  fluids.

Ear Notching

• Why?
• Producers must be able to identify pigs from
  birth.
• Notching provides
• 1. A permanent ID system
• 2. Individual identity for all animals
• 3. Inexpensive means of identification

21
Animal Management Tools

• A V notcher is used to notch the ears of swine
  for identification.

22
Ear Notching do not write

• An example of an ear notching system employed by
  many farmers.
• The position of the notch represents a certain
  number as seen above.
• The quadrants are 1, 3, 9, and 27.
• A notch at the tip of the ear represents number
  81.
• Two notches are allowed in each quadrant.

23
Ear Notching

• Litter Mark The right ear is used for litter
  mark, and all pigs in the same litter must have
  the same ear notches in this ear.
• Individual Pig Marks The left ear is used for
  notches to show an individual pig's number in the
  litter. Each pig will have different notches in
  the left ear
• In this case the pig is from litter 160, pig 1
  (count up the numbers).
