This breed matures in 7 to 9 months

Berkjala

entirely white with erect ears that is not big. sows have superior mothering ability; farrow and wean large litters and are excellent milkers. Adopt well to confinement but not on rugged condition prone to disease

Yorkshire or large white

white; short legs with medium to large drooping ears; short snout. - good mothering ability and litter size produce pig of highly acceptable carcass quality

Landrace

Weak on the feet and legs and have problems adopting to rugged condition but it can be corrected by proper selection and breeding

Landrace

Color ars varying shades of red. Produce pig that have superior rate of growth; feed conversion and their performance in rugged condition is better than any whites breeds

ears are small (⅔ erect and ⅓ drooping a tip)

Colored black with white belt around the shoulder and body. Long-legged and lack body thickness Able to adopt to very rugged conditions -

Hampshire

Berkshire

Spotted black and white with medium -sized ear pointed upward, sometimes slightly drooling. Its snout is moderately long and dished

Pietrain

Do not have distinguishing physical characteristics that may differentiate them from other pigs

Synthetic breeds

Genetic engineering involving the application of comprehensive testing procedure and is computer aided. It aims to take advantage of hybrid vigor or heterosis

Synthetic breeds

This breed was developed from 4 synthetic lines from carefully selected stock of Euribrid, Europe a leading animal breeding organization. The sow are excellent fertility; outstanding mothering characteristics and high milking qualities

Hypor

Corporation of Neuw Dalland

Dall Phil System Corp.

The countries most major distributor of new Dalland, they will have the highest number of breeders in the country

Dall Phil System Corp

This breed has evolved from continuous selection and cross breeding of other excellent breeders namely Landrace, large white and pietrain

Neuw Dalland

Has excellent quality with minimum backfat

Are systems of mating animals used to produced a purebred or a crossbred, which is important in pig improvement to increase production

Breeding systems

Is done to purify the bloodline of the animals since the similarity of the animals within the group is increased

Inbreeding

Is not recommendable due to its negative effect on the production performance of the animal. It usually decreases vigor because it brings together the recessive genes

Continuous breeding

Cross breeding system is recommended for the production of market hogs of 2 important reasons:

To obtain hybrid vigor or heterosis To bring together the desirable characteristics of the parental breeds

A system of breeding wherein an inferior breed is improved by continued crossing Commonly used among native breeds crossed with exotic breeds of swine to improve the common sick

Upgrading
