Chicken broiler and egg production are the most progressive animal enterprises in the Philippines today. The poultry industry in fact began as the backyard enterprise but has shifted to the formation of very large integrated contract farming operations.

The growth of poultry industry in the Philippines has been impressive but its problems include inefficient management and the prevalence of many destructive poultry diseases and parasites cannot be ignored.

This manual provides technology and management know-how for poultry raising which we hope present poultry raisers and prospective poultry producers may find useful in effectively managing their poultry farms and also help them realize substantial financial returns from their enterprise in this period or high production cost inputs.

The Chicken: Classes, Breeds and Varieties

The chicken is the most exploited species of poultry, which is utilized for food production in the whole world. Scientific researchers have been done on this species for past centuries and it is still the focus of the present and future experimentation. In the Philippines chicken rank first, while ducks rank second in economic importance as source of meat and eggs.

Breed of Chicken can be classified by its utility. This is based on the purpose for which the breed or variety is most efficient.

• Egg Class – The breed belonging to this class is characterized by their comparatively small size. They lay large white shelled eggs, very active and nervous in temperament. They are non-sitters. The earlier selection of geneticist for this class showed record of early maturity that may not necessarily be true with the modern breeds under this class. Examples: Leghorn, Minorcas, Anconas, Mikawa.

• Meat Class – to this class belong the breeds that are large, slow movement, quiet and gentle in disposition. Geneticist of the past described them as relatively slow maturing which may not hold true anymore with the present meat breeds. They are generally poorer egg layers and generally lay brown shelled eggs. Examples are: Brahmas, Cochin,Langshans, Comish, White Rocks.

• General Purpose Class – Breeds of Chicken in this class are medium sized good layers and the young are fast growers. They are not s nervous as the egg class but much more active than the meat class. Examples are: New Hampshire, Rhode Island Red, Plymouth rock, Lancaster, Nagoya, Cantonese.

• The general purpose breeds had its popularity period when the idea of the poultry breeder was to hit both products of eggs and meat in one kind of breed. Later developments proved that specialization of breed purpose is better goal for more efficient production. The general purpose class at present has been modified and developed by breeders in the production of broiler chicks.

• Fancy class – The breeds under this class may be characterized as possessing decided beauty of plumage or form of having a rare unusual appearance. Most of them are raised chiefly as ornamentals or pets by hobbyists, regardless of their value as source of food. Example: Frizzle, Bantams, Long tailed.

• Fighting Class – Since this sport is now legalized in the Philippines it should revolutionalize our original vision that fighting cock breeds has no place place for our study. There are groups of this kinds of chickens now developed by national and international aficionados in this game. Since there are no studies conducted on the breeding and raising of these game fowls, the LAS could not profess any knowledge of what kind and what process of raising will assure a cock to win in the fight. The popular ones are the Ruble, Hulsay, Claret, Oasis
