Q

Breeding PIDGEON (Goals, use, breeds, methods)
Use of pigeons (breedinggoals and purpose)
- Comercial

A
  • Comercial (Meat production)
  • Food (SQUABS): Harvested from young birds. Pidgeons grow into a large size while in the nest before they are fledged and able to fly (called SQABS). At that stage = PRIZED as FOOD.
  • Commercial meat production breeds where developed by selective breeding (king pidgeon etc)

Use of pigeons (breedinggoals and purpose)
  • Hobby (sport, show)
A

1- Exhibition breeds (fancy breeds)
Compeete against each other at exhibition/shows.

2- Flying sports pigeons (tipplers)
Flown in endurance contests
- Trained domestic pidgeons are able to return home if released at a location upto 1000km

3- Homing Pidgeon (selective breeding);

  • Carry messengers
  • Racing pidgeons
  • White release at funeral/weddings

Q 
Breeding PIDGEON (Goals, use, breeds, methods)
Methods
A
  1. Selection
    - Mating system is typically monogamy, but forced pairing is possible.
  2. Purebreeding
    - With individual and phenotype selection dominates
  3. Crossbreeding
    2-,3- and 4-way; Meat production, hybrid program.
    (Breeds to cross: Strasser, Mondain, King and Texan

Breed for 3-4 year

21
Q

Breeding HENS(Broiler?) (goals, use, species, breed methods, traits, Hybrids)

For Egg production

A

Hens (Laying Breed): 300/year
12mnth of age: laying ability decrease
Commercial laying hens slaughterd (baby food, Pet food)
Laying Breeds: White Leghorn and Hybrids

Breeding eggs are produced from incubation

22
Q

Breeding HENS(Broiler?) (goals, use, species, breed methods, traits, Hybrids)

Meat Production

A

Lifespan from 5-11 years
Comercial farm, meat production meat chicken lives for apron 6 week (slaughtered)
Free range/organic: 14 weeks for slaughter

Meat fowl:

  • Plymouth Rock
  • New Hampshire
  • White Cornish

Chicken (pets) + Ornamental (Zoo -Used to controll Insect population)

23
Q

ORIGIN and DOMESTICATION of Poultryspecies, microevolutionary consequences on meat and egg production on different poultry species in human nutrition

Main consequences of domestication
Chickens

A

Chickens: Increase Body weight, size

Highly affected character are the Fertility, Prolificacy, and other reproductive features

24
Q

ORIGIN and DOMESTICATION of Poultryspecies, microevolutionary consequences on meat and egg production on different poultry species in human nutrition

Turkey:

A
  • Accumulation of plumage(turkey feather)
  • Colour variation and Patterns and Features (Frizzle, Naked neck) + Limb alteration, Muscle attachment etc.
    Muscle HYPERTROPHY!

Highly affected character are the Fertility, Prolificacy, and other reproductive features

25
Q

ORIGIN and DOMESTICATION of Poultryspecies, microevolutionary consequences on meat and egg production on different poultry species in human nutrition

Duck/Goose: Fat deposition

A

Duck/Goose: Fat deposition

Highly affected character are the Fertility, Prolificacy, and other reproductive features

26
Q

Breeding Turkey ( (Goals, use, breeds, methods)

A

Wild Turkey, Mexico 1000BC
Bred for their colour plumage first and raw meat quality

Broad Breasted Large White (Meat)
Broad Breasted Bronze (Less popular, as white feathering is more preferred)

Broad Breasted Large White
(Broad Breasted Brinze * White Holland)

At 20-21 degrees, the turkey gives the best feed conversion ratio. But put on more body weight and yield more brest meat at lower temperatures.

27
Q

BROODING

A

= Application at heat to birds at early age of life

Newly hatched at 38 degrees
Placed in draft free surroundings at 37 degrees for the first day, reducing with 0,5 degrees/ day, until they are sufficiently well feathered –> Thrive no artificial heat.

Kept dry

Brooding area: Min 2 inches at litter

Good Litter: Clean, Dry, Dirtfree and Absorbent

LIGHT:
24 h/day first week
After=? 12-14 hours /day
Exessive light: Canibalism in young poultry and Pilling

VENTILATION is IMPORTAINT!

28
Q

Breeding Goal (USE): Turkey meat production and breeding (Fattening, Broilers)

Use:

A
  • Egg production for hatching
  • Selection: Meat Quality, Hatchablility, Early Maturity
  • Species features: Sexual maturity in first year, Cluch sized eggs.
  • Egg weight: 65g
  • Incubation time: 26-28 days
  • Sexual dimorphism (typical), Increased by domestication, especially in males.
    Males may exceed 20kg, 10kg in wild
    Females half?
29
Q

Breeding Goal (USE): Turkey meat production and breeding (Fattening, Broilers)

REPRODUCTION

A
  • Puberty, laying and sexual maturity:
    Female: 16 weeks
    Males: 24-26 weeks
  • Start at laying: at 34 weeks
    Egg-laying productions:
    90-125 eggs/year, weight 75-85g
  • Duration at laying period: 20 weeks
  • Broodiness (=Behavioural tendency to sit on the clutch to incubate them) STRONG INSTINCT
  • INCUBATION time: 28 days
  • Hatchability at egg breed is important.
    Sex ratio 1:10
30
Q

Breeding Goal (USE): Turkey meat production and breeding (Fattening, Broilers)

MEAT PRODUCTION and PERFORMANCE

A 
Growth up to 24th week is excellent
Feed efficiency, Conservation.
Dressing percentage carcass/life * 100
Carcas ratio
Feathering period females: 14-16
Feathering period males: 22-26
Pronounced sexual dimorphism

AFRAID of OTHER BIRDS

31
