This method establishes minimum standards for each character, and selecting simultaneously but independently for each character.

Philippine warty pig

This breed is common particularly in China. Well-known for its prolificacy, early sexual maturity ranging from 2.5 to 3 months and large litter size (15 to 16 piglets)

result from corssing Native Pig (Ilocos) + Berkshire

Originated from Southern England. This breed have white belt around the shoulder and body including the foreleg.

Two way of selection

mating with the use of four different breeds.

This breed is known as “muscle pigs” because of its outstanding muscle development in the ham, loin and shoulder. Spotted black and white color

system of breeding wherein animals of the same breed are mated to each other but not closely related

mating with the use of three different breeds.

This method combines all important traits into one overall value or index.

It is the method by which a pig raiser determines whether a sow will accept service by the boar.

Phases of Estrous Cycle

Refers to the removal of unwanted animals in the herd.

It is a system of breeding wherein an inferior breed is improved by continued crossing. It is commonly used among native breeds. The native breeds are usually crossed with pure breeds of swine.

They are generally small Mature females weigh about 30 to 40 kilograms Boars weigh about 40 to 50 kilograms.

This method is done by applying pressure on her sides with both hands.

A vasectomized boar is the best animal to use in this method.

There are five strains of pigs developed and documented in the Philippines that contained genes of native pigs:

(Milk Production)

Mating System

Average of gestation period

It is known to produce large litters, docile with good mothering ability and rebreeding ability.

Success Triangle Program

Origin First develop in Denmark for the production of bacon. Characteristic: White in color Longest breed of swine with 16 to 17 ribs. Known for its prolificacy and mothering ability under Philippine condition.

➤ the time interval from weaning to service ➤ This is the time when the sow is unproductive. ➤ The length of the dry period varies depending on the sow's body condition ➤ Ideal dry period is 7days

In this method, selection is done on the basis of the individual's record of inheritance.

originated in the Eastern United States Have a solid colors ranging from very high light golden to very dark red that approaches the color of mahogany.

Two types of culling

Types of crossbreeding

mating with the use of two different breeds.

This are the systems of mating animals to produce a pure breed or a crossbreed.

Lactation last about?

it is the result from crossing the Native Pig (Batangas) + Berkshire

Palawan Bearded pig

• Also known as heat period • Lasts from one (1) to five (5) days with an average of 2-3 days

➤ the secretion of milk from specialized glands (mammary glands) to provide nourishment to offspring.

SWINE HYBRID

developed by PIC 35 years ago and the name become synonymous with prolificacy.

was develop in 1916 at UP College of Agriculture. This is the result of crossing Native Pig (Jalajala, Rizal) + Berkshire. It has 75% dressing percentage.

Types of breeding system

Time during which the sow will accept the boar (sexual receptivity)

The best boar gets the best sows, while the weak, sickly and poor ones usually die naturally and have lower chances of breeding other animals. As time goes on, the herd is getting better ("survival of the fittest").

Selecting Gilts

Pointers in Culling Boars and Gilts/ Sow

This refers to that system in which there is selection for only one trait at a time

How many months is final evaluation

With this technique old semen sample is squeezed from a squirt bottle on the snout of the sow.

In a herd, it is common to cull at a rate of

Did you know that??

= it is intermediate between the lard and the bacon type of swine.

Methods of Selection

Refers to the result to large improvement in the average performance of the F1 progeny over that of the parents. Is defined as the change in performance of the crossbred progeny over the average of the parental breeds

Estrous Cycle

Factors Affecting Sexual Maturity

common in the province of Batangas. It is the result from Native Pig (Batangas)+ Duroc

This breed originated from Yorkshire and neighboring countries of Northern England. Characteristics White in color. Large litters Have erect ears Good mothering ability Excellent milkers Strong legs Adapt well to confinement

This are the results of a combination of the good characteristics traits of superior genetics breeds.

It was developed in the Netherlands by a group of breeding companies called TOPIGS. The foundation breed is the Pietrain along with Largewhite and Landrace

Types of selection that have human intervention

reddening of vulva and mucus discharge

Criteria for Culling Boars

Selecting Boer

Methods of Selection

Techniques of Heat Detection

This are the breeding of closely-related animals.

the period from fertilization to farrowing time

This is done by riding on or pressing the back or loin of the sow.

-long period of inactivity

Originated from South Central England, The color is black with six white spots, four white feet, one on the forehead and another on the switch of the tail.

(Milk Let-down)

How many months is Initial Evaluation

is a systematic way of choosing the desired characteristics of pigs for breeding purposes.
