1. PIG BREEDING DR. EDITH E. CABILITAZAN, DVM Resource Person ATI-International Training Center on Pig Husbandry Marawoy, Lipa City, Batangas

2. Objectives Identify common breeds and their traits Enumerate breeding systems Identify methods of breeding

3. Outline I.Breeds of Pigs II.Breeding system III. Breeding Methods

7. INTRODUCTION Performance of pig is influenced by its environment and its genetic potential Proper choice of breeding system leads to genetic improvement! P = G + E

8. Breeds of Pigs

9. WHAT IS A BREED animals with common and specific traits or characteristics Mating within the breed produces progeny that maintains the same set of characteristics. Genetically pure to have similar external characteristics of color and conformation.

10. 1. Duroc Origin-New York/New Jersey Traits: Ears - Droopy Color- Cherry Red or brown Fast grower Good body conformation

11. 2. Large White Origin- England Traits: Ears – small, erect Color - fine white Good body conformation Prolific Excellent milker

12. 3. Landrace Origin-United States Traits : Color-White with freckles Ears – Large & Drooping Long body prolific  weak pasterns

13. 4. Pietrain Origin- Belgium Traits: Ears - erect Color– spotted Muscled  Prone to stress

14. 5. Philippine native Upgraded native pigs

15. Origin - Philippines Traits: Color- Black Early maturing 120 kg adult size

16. BREEDING SYSTEMS systems of mating animals to produce a purebreed or a crossbreed important in pig improvement since use of the correct system can greatly increase production.

17. INBREEDING  Breeding of closely related animals  done to purify the blood line of the animals  Continuous inbreeding is not recommended due to its negative effect on the production performance of the animal  decreases vigor because it brings together the recessive genes with undesirable effects in the resulting crossbred.

18. Largewhite (Father/sibling) Largewhite (daughter/sibling)

19. PUREBREEDING  Breeding of unrelated animals of the same breed  done to maintain the production supply of the breed

20. DUROC bOAR Duroc gilt

21. CROSSBREEDING  Breeding of two animals from different breeds  It is highly recommended for the production of market hogs  to obtain hybrid vigor or heterosis which is defined as the change in performance of the crossbred progeny over the average of the parental breeds  to bring together the desirable characteristics of the parental breeds.

22. DUROC JERSEY PIETRAIN Duroc x Pietrain Boar

23. Hampshire x Duroc Boar

24. Crossbreed Gilt

25. Hybrid Pigs Topigs Seghers Hypor Camborough-22

26. BREEDING METHODS Describe the method or how to produce progenies/offpsprings The choice of method will affect the number of boars to be kept in the farm It also determines the required facilities in the pig farm
