1. BREEDING IN GOAT AND SHEEP

2. Breeding is concerned not only with the reproduction or multiplication of the animals, but also with the improvement of flock and project efficiency

3. Breeding Systems Upgrading or Grading up – This is the cheapest breeding system aimed at increasing the exotic bloodlines of usually native breed. It is the mating of a native, or unimproved female with a purebred or exotic chicken.

4. 2. Purebreeding In this system, a purebred male is mated with a pure bred hen of the same breed. This mating is also called straight breeding. This is practiced when a raiser wants to maintain primarily the purity of his stocks

5. 3. Crossbreeding This is a mating of two animals belonging to different breeds. This is practiced to take advantage of hybrid vigor and to elicit the desirable characteristics of parental breeds.

6. 4. Inbreeding This is the mating of closely-related animals. It is used by animal breeders in the production of seed stock, and in the development of new lines or breeds

7. Close Breeding- breeding of closely related animals. Ex. Mother and son, brother and sister Line Breeding- breeding of related but not that close to each other. Ex. Cousins, tito and niece

8. MATING SYSTEMS Natural Mating or Hand Mating This type of breeding involves the complete confinement of the boar in a separate quarter; it is not allowed to be mixed with the rest of the herd .

9. When a sow is “in-heat”, it is either brought to the boar or the male is brought to the sow and they mate with or without the assistance of the caretaker. This is termed hand mating.

10. Pasture mating This permits the boar to run with the herd throughout the breeding season or throughout the year. Breeding naturally takes place in the area.

11. Artificial Insemination (AI) AI is a reproductive technology in which the semen is collected from boar and then used in fresh or frozen form to breed sow through artificial means.

12. Artificial Insemination offers a great potential in accelerating the genetic improvement of the pig population because AI allows a size to produce potentially hundreds, if not thousands, of progenies.
