Personal likes and dislikes in terms of caring for the animals
Is a group of animals that has specific traits or characteristics in common
Breed
Mating within the breed produces this that maintains the same set of characteristics
Progeny
The performance of pig is influenced by this which includes nutrition and feeding, housing, health etc. compromising 70% of the totality of the animal
Environment
Compromising 30%, thus it is important to look into the bloodline of the animals
Genetic Potential
This pig is hardy (healthy or strong or daring). It’s upkeep is not expensive. The female forrows regularly. The snout is long and pointed.
The ears are small and erect.
The back is low and stomach hangs close to the ground.
The litter is small and of different colors which may either be black or black and white
The native pig
The breed is wild and hard to handle even after long confinement.

Classified into 2 strains which are both lard and meat type
Batangas pig
The looks and size are similar to Duroc Jersey
Kamain
Black color similar to Berkshire and Poland china
Diani
Both are produced by natural cross breeding and ready for market at 9 months old
Kamain
Diani
An intermediate between lard and bacon type the breed is found in Cotabato
The koronadal pig
The size satisfactory. The head is long and the snout pointed and long. The pig matures at 9 months
Koronadal pig
The cross between the native Bekjala and the Berkshire.
The breed is better than any native pig it’s big size and of lard type. The body is moderately long.
The ears are large and erect and the legs are big boned and strong
Berkjala
Who perfected the berkjala breed in UPCA in Los Baños, Laguna in 1916
Dr. B. M. Gonzales

Mature sow berkjala weighs how many kilo?
120 kgs
Dressing percentage of berkjala
75%
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
Duroc
ears are small (⅔ erect and ⅓ drooping a tip)
Duroc
Colored black with white belt around the shoulder and body.
Long-legged and lack body thickness
Able to adopt to very rugged conditions
-
Hampshire
Black with six white points (4 white feet some white in the face and tail.
Ears are erect
Known for their meatiness and good adaptability to rugged conditions
Sows are not as prolific as the other breeds but produce well when crossed with other breeds
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
Neuw Dalland
arrived the country in 1975 was considered as the best source of lean meat.
It great grandparents are from Belgium and was imported by Robina Farms
Seghers
A product of Vitarich corporation
Babcock
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
Good production of the sow
18 piglets
Long life
6 litters
Good ADG for the offspring
650 grams
Good FCR of the offspring
3.0
Oviduct distended with fluid

Pyosalpinx
Blind uterine body, infantilism cystic ovaries
Unilateral blind uterine horn
