Breed

Distinguishing traits of breeds of poultry species are plumage color and pattern, comb type, and body size

Egg Meat General Purpose Fancy Fighting

Utility Classification

Egg Type

characterized by their comparatively small size - lay large, white shelled eggs - very active and nervous in temperament - non-sitters - examples: Leghorn, Minorcas, Anconas, Mikawa

Meat Type

large, slow in movement, quiet & gentle in disposition - generally poorer egg layers - lay brown shelled eggs - examples: Brahmas, Cochin, Langshans, Cornish, White Rocks

General Purpose Type

\- medium sized good layers - the young are fast growers - not as nervous as the egg class but more active than the meat class - examples: New Hampshire, Rhode Island Red, Plymouth Rock, Lancaster, Nagoya, Cantonese

Fancy Type

\- possessing decided beauty of plumage or form of having a rare unusual appearance - raised chiefly as ornamentals or pets - examples: Frizzle, Bantams, Long Tailed

Fighting Class

developed by national and international aficionados in this game - examples: Ruble, Hulsay, Claret, Oasis

American Class

Origin – America

bred for egg and meat - considered as brown egg layers with yellow skin - examples: Wyandottes, New Hampshire, Rhode Island red, Lancaster

Asiatic Class

Origin: Asia - with yellow skin, large bodies which are squarely shaped - examples: Brahmas, Cochin, Langshang, Cantonese, Nagoya

Mediterranean Class

\- Origin – Europe - smaller than American and Asiatic class - clean legged with white creamy earlobes - produce white shelled eggs - example: Leghorn, Minorcas, Anconas, Hambury, Polish, French

English Class

- Origin – English - for egg and meat production - have excellent fleshing quality - examples: Orpington, Dorkings, Australops, Cornish

Native Chicken

\- descendants of those from continental Asia - land bridges (supposedly connected the archipelago to mainland Asia) - introduced during the early trade - examples: Labuyo, Bolinao of Pangasinan, Banaba of Batangas, Camarines of Bico

Poultry Breeding

a scientific practice which aims at genetic improvement of the birds through successive generations by virtue of planned reproduction -

the aim is to improve the performance of the flock

Selection

\- the process of choosing individuals to be parents of the next generations

Natural and Artificial

2 types of selection

Natural Selection

\- Survival of the fittest - Climate change - Different in nutrition

Aritficial Selection

Interference of man in achieving certain goals and personals ideas - Example are meat, eggs, fighting cocks, fancy feathers

Feed Conversion Efficiency (FCE)

the amount of food we need to gain 1 kilo

Inbreeding

\- mating of closely related individuals

Outbreeding

breeding of unrelated animals, with mating pairs possessing different ancestries or pedigree

Cross Breeding

- mating of two different breeds or two inbred lines or pure strain of the same breeds

3-way Cross (Triple Crossing)

involves three generation scheme of breeding

Upgrading

the mating of a purebred to native hen and the most popular breeding system among backyard farmers

Mass/Flock Mating

mating of large numbers of birds. wherein two or more males

are mated with several females housed in single pen - the fertility is generally high and, therefore, much desirable for producing chicks meant

Pen Mating

the fertility is lower in this mating compare to flock mating due to preferential matings

Stud Mating

mating of individuals with a male in a cage (common in game fowl breeder) more offspring’s can be obtained from sire of high

merit

Artificial Insemination

\- a method wherein semen are collected from superior males - this mating system is used when: - natural mating is not possible - females is kept in laying cages - breeding is used for experimental

Culling

\- removal of unproductive birds from the flock

Biology Engineering Economics

\*Factors to Consider in the Design and Construction of Houses

Shed Type

Roof type: single span

Gable Type

Roof type: conventional can be even and uneven

Monitor Type

appropriate for which big houses need better air circulation

east-west

\- Orientation should have an ____ orientation

Footbaths

should be installed at each entry/exit point of a poultry house

Growing House

similar in all aspects to broiler house

Laying House

\-individual cage should provide a floor space of .5 ft2 trough feeders and waterers are installed on the

front side of the cages. The waterers are placed above the feeders

Grow-out House

house : just like with litter leg and foot

broiler house but flooring to prevent injuries

Laying House

may be pure litter, pure slat type, or combination litter and slat type

Feeding Method

The growth performance of the animals is not only affected by the quantity and quality of feed given but also by the method of feedings

Restricted Feeding

the amount of feed given is controlled or limited to a certain amount just to satisfy the appetite of the animals

Restricted feeding

is done through the use of a long feeding through where all animals eat at the same time. However, the length of the trough should be long enough to accommodate each during feeding time

Ad libitum Feeding

\- is feeding without restrictions and feed is made available in anytime - fresh feed improves the feed intake and feed efficiency
