-
Types of Cannibalism
- Toe Picking- pick tissue off of toe
- Tail Picking- Occurs when molting
- Vent Picking- Cloaca comes off when laying an egg. It gets picked and causes prolapse
- Black Pot- eat all or most of chicken
-
Triggers of Cannibalism
- Light Intensity
- Hours of light- have to have dark cycle
- Genetics
- Disease
- External Parasites
- Juvenile Molts
- Crowding
- Nutritional Deficiencies
- Mixed Age/Specie
- Peck Order
- Boredom
- No Feed
-
Does lack of water cause cannibalism?
No it makes them lethargic
-
Genetic Triggers
- Fighting Chickens
- Pheasants
- Leghorns
-
External Parasite Triggers
- Northern Fowl Mites
- Poultry Lice
Picking them off causes cannibalism
-
Nutritional Deficiency Triggers
- Salt (sodium)
- Protein
- Amino Acid
-
Nutritional Methods of Control
- More Salt
- More Protein
- Balance the amino acids
-
Anti-Picking Control Apparatus
- Red Contact Lenses
- Specs (blinders)
-
Distractions Method of Control
- Alfafa Hay
- Plastic Bottles
- Beach Balls
- Baby Toys
-
Correct Management Problems
- More space per bird
- Lower the house temperature
- Increase the air flow
- Feed the birds (Fix the feeder)
-
Methods of Beak Trimming (Beak Conditioning)
- Laser: done at hatchery
Precision Beak Trimming: 2.25 seconds, 6-7 days old, quick recovery"Nip" Beak Trimming: 7-21 days old, top beak only - "Final" Beak Trimming: 6-12 weeks of age, top and bottom (not as common anymore)
-
Phases of Incubation
- Setting Phase (Setter): all but last few days, turning device
- Hatching Phase (Hatcher): last few days, no turning device, higher humidity
-
5 Key Factors of Incubation
- Temperature
- Relative Humidity
- Air Exchange
- Turning
- Position of the Egg
-
Time Requirements of Incubation of:
Chickens
Ducks
Turkeys
Quail
- Chickens: 21 days
- Turkeys: 28 days
- Ducks: 28-35 days
- Quail: 17 days
-
Temperature: Optimum Temps
- Some eggs will hatch 95-104 degrees
- Forced Draft: 98.6-100.4
- Still Air: 99.6-101.4
- Hatching Phase: 98.0
-
Heating and Cooling Temps
- Days 1 to 13: Heating
- Days 14 to 21: Cooling
-
Humidity Requirement:
- Setting Phase: 58-61%
- Hatching Phase: 75%
-
Methods of Measuring Temperature
- Percent Relative Humidity
- Wet Bulb Temperature
-
Humidity Affects:
- Weight Loss
- Chicks ability to get out of shell (necessary for this)
- Early Hatching (those who hatch early need humidity)
-
Optimum Level of Oxygen
21%
-
Optimum Level of Carbon Dioxide
- 0.5%
- if it goes too low then the repertory system won't develop
-
Why do eggs have to be turned?
To keep the yolk centered
-
How many times a day does the hen turn the eggs?
200 times per day
-
According to research, how many times do the egg have to be turned?
6-8 times per day
-
How many times do hatcheries turn their eggs?
24 times per day
-
Position of the Egg
- Large end up= commercial egg industry
- Laid on its side= when hen lays egg
Chalaza is there to keep the egg centered when turning
-
How to find Optimal level of moisture loss:
Egg Wt. - (chick wt.) - (shell wt.)= moisture loss
- Should be around 11.5%
- 9.5%= Mushy chicks
- 13.5%= Dehydration, Death
-
Factors Affecting Moisture Loss
- Egg Shell quality (porosity)
- Temperature and Humidity During the Storage of Hatching eggs
- Length of Storage
- Temperature and Humidity During Incubation
- Egg Size
-
Further Processsing
any processing applied to a dressed poultry carcass following the whole body, ready to cook stage
-
Gobbler
A mature male turkey
(A tom is a male of any age)
-
Grower
contract grower, a poultry grower
-
High Rise House
- Two story house
- Cages on top, feces on bottom
-
Hock
joint located at the juncture of the fibula
-
Hover
a metal hover or canopy which contains and directs the heat generator by the heat source
Doesn't warm air, but warms surfaces
-
Hybrid Vigor
the extra performance shown by the progeny of crosses genetically dissimilar stocks
-
Integrated
Business which is engaged in contract production of poultry meat or eggs
-
Leaker
egg which has a crack, the contents are exuding or can exude through the shell
-
Light and Temperature
Excludes natural daylight and has a system of mechanical ventilation. All lighting is artificial.
Conventional: use natural light; opposite of LTC & stirring fans
-
Litter
- Rice hulls absorbent material. Functions:
- Absorbs H2O
- Temperature control
- Cushion (not bedding)
-
Loss Egg
- to be inedible and not suitable for human consumption
- have adhering material on the shell
- Cant sell a dirt to a store
-
Mash
a from of feed consisting of a mixture of ground ingredients
-
Meat Spot
- any particle of foreign material found in the albumen of an egg.
- Small piece of oviduct
-
First three things you do in table egg industry
- Facility (cage, cage free, free range)
- Schedule
- Select the right strain
-
Selection Factors that are controlled by genetics
- Rate of Lay
- Mortality
- Temperature
- Egg Size
- Body Weight
- Feed Consumption
- Shell Quality
- Forgiveness
- Moltability
- Internal Egg Quality
- Shell Color
- Others
-
Factors Inherent (present) in your company/facility
- Housing Type
- Where are the eggs marketed
- Flock Scheduling
-
Sex Slip
Where they make a mistake and send a boy instead of female
-
Types of Equipment and systems
- Floor House
- Cage House - 3x better utilization (no wasted space)
- Combinations
-
Feeding Systems
- Cage: Flat chain and drag auger
- Floor: flat chain and pan (auger to pan)
-
Watering Systems
- Trough (with float control)
- Cups (with float control)
- Cups with pressure regulator
- "Bell" type waterers (valves controlled by weight)
-
What is the most popular watering system?
Nipple watering system
-
Why is nipple watering systems the most popular?
- No floor space required
- Ease of drinking (drink more b/c of angle)
- Stays clean
- Low water pressure
- Less labor
- Less disease/ Use of medications and disinfectants
- Better feed efficiency
- Disadvantage: hard to drink for runts
-
What is used to increase the calcium level and why?
Oyster shell because it is selective and they wont eat it if they don't need it
-
Vaccination Programs
- 3 week spread
- Minimize combinations
- Use fresh vaccine (have pull dates)
- When water vaccinating: the stock solution should be consumed within two hours
- When water vaccinating use evaporated milk
- When spray vaccinating use distilled water
-
Titer
Fancy word for concentration of the level of antibodies
Normally on a scale of 0 -> 18
