  1. Breeding Systems http://www.heltonplastics.com/quality-and-durability-as-only-helton-can-make-it/silhouettes/small-cow-calf-pair

  2. Breeding Livestock Animals • Various breeding systems exist due to the various types of livestock operations. • The size of the herd, amount of money available and goals of the producer are all factors that determine the type of system used. • Some farms use more than one type of mating system. • In general, cattle use all types of breeding systems while swine and poultry tend to utilize crossbreeding to develop industry owned hybrids.

  3. Types of Breeding Systems • Straightbreeding- mating animals of the same breed. Types of straightbreeding systems: • Purebred • Inbreeding • Grading Up

  4. Types of breeding systems • Purebred breeding: a registered purebred male and female of the same breed • Example: Angus x Angus                    Krugerrand of Donamere 490          B&J Krugerrand 6066                    B&J Barbara 8366BAF Donamere 9196                    Womack Dark Max 131          B&J Barbara 4196                    B&J Barbara 9896                     Hoff Hi Flyer SC 7134          Whitestone Fly Traveler 3006                    TC Jestress 6004DB Lady Flyer                    Hoff Great Wegstern SC 456          Lady West                    Master Lady 563-9 BW: +2.0 WW: +46 YW: +95 Milk: +16 Feed Lot Value: +36.83 Wearing Wt.: 816 Yearling Wt.: 1520 30 Month: 62.5'           3175

  5. Types of breeding systems Inbreeding- mating closely related animals. Increases the genetic purity of the stock produced, but is not used as often by the typical producer. Two types of inbreeding: • Closebreeding • Linebreeding

  6. Types of breeding systems • Closebreeding:mating animals that are very closely related. • Examples: brother x sister • Son x mother • Father x daughter

  7. Types of breeding systems • Linebreeding: breeding more distant relatives than inbreeding, and can be traced back to one common ancestor • Example: cousin x cousin

  8. Types of breeding systems • Grading up: mating purebred males (sires) to grade or unregistered or crossbred females (dams) to improve the herd • Example: Yorkshire boar x Yorkshire-Hampshire sow

  10. Types of breeding systems • Crossbreeding: mating a male and female of different breeds • Examples: Angus x Hereford= crossbred calf; • Crossbred x Purebred=crossbred; • crossbred x crossbred= crossbred

  11. Black Baldies(Angus x Hereford= crossbred calf)

  12. Types of breeding systems • Hybrid vigor: the superior traits that come from crossbreeding causing the offspring to have traits better than either parent = Heterosis

  13. Types of breeding systems Crossbreeding Systems Include: • Terminal sire- replacement females are bred to a sire and all offspring are sold. • Rotational- uses a two, three or four breeds to rotate between sires and females. This system requires more intensive management.
