Vocab Egg Laying, Meat, Dual Purpose, Ratites

6  Students will:  Identify major breeds of chicken and minor breeds of poultry  Describe characteristics of each breed  Identify breed purpose

7  What are purposes of poultry? (think terminology)

8 Breed (Specific)Type (General)3 FactsPurpose (with definition) LeghornChickenLays white eggs, Loud, Always all white Table Egg Laying: lays eggs for human consumption.

9  Fowl (birds) raised on farms and used as food

10  “Chicken is the number one most consumed meat in American”  Discuss: Do you feel this is true why or why not?

11  High protein  Low fat  Economical to eat  2nd in consumption only to beef

12  Meat- Plymouth Rock  Feathers- Peafowl  Eggs- Leghorn  Showing- White Crested Black Polish

13 Dual Purpose Meat Purpose Fancy/Ornamental Table Egg Laying

14  Weighs: 4 lbs. to 6 lbs.  Egg Shell Color: White.  Use: An egg-type chicken.  Origin: city of Leghorn, Italy.

15 Characteristics: A small, noisy bird, known for being all white in color  The most numerous breed.

16  Standard Weight: 5 ½ lbs to 8 ½ lbs.  Egg Shell Color: Brown

17  Use: Egg production, and meat (Dual Purpose)  Origin: Massachusetts and Rhode Island.

18  Recognized for its long wattle and head plumage  Originated in Poland

19 Can only see forwards and downwards  Considered ornamental/fa ncy

20  Famous for its fighting skills during the revolutionary war.

21  Delaware’s regiment was nicknamed “The Blue Hen Chickens”  Not a “TRUE” breed  University of Delaware’s mascot  UD has one of the only remaining pure bred flocks

22  Any breed of chicken raised specifically for meat. (Typically Plymouth Rocks)  Grown to specific weight and age.  Between 5-12 weeks in age. Average is 7 wks from egg to processing  Selected to gain lean (no fat) weight quickly

23  Most common widespread goose in America is the Canadian Goose  A group of geese is called a gaggle  Hunted for sport. Meat and feathers are used  Large waterfowl in between a swan and ducks.

24  Very heavy birds (40-60 lbs)  Wild Turkeys hunted for sport. Meat is more “gamey”, weigh less than industry birds  Selectively bred for large size

25 All industry produced turkeys bred for meat must be artificially inseminated because they are so large!

26  Produce eggs, meat, and feathers (down feathers)  All duck breeds are descendants of wild mallard  China is top duck market

27  Used for meat, eggs  Normally eaten meat and bones  Wild Quail that has fed on hemlock, can be toxic to consume causing kidney failure

28  Flightless !!!  Birds in this group include; ostrich, emu and kiwi  Ostrich and emus used for eggs and medicinal purposes  Emu oil provides health benefits for painful joints and bruises  Emu’s cannot walk backwards

29  Put your name and the date on your worksheet packet  Define the following words:  Poultry  Dual Purpose (give breed example)  Table Egg Laying (give breed example)  Fancy/ Ornamental (give breed example)  Meat Purpose (give breed example)  Broiler  Gaggle  Ratites

30  Person A  Give the word and the definition  Person B  Use the vocab word in a sentence

31 Library Project (Optional) Directions: Choose a poultry breed not discussed in class. Provide a picture to the teacher (chosen from the internet) to be posted on the screen while you present.

32 Library Project Compile a profile of your bird. Include: Origin Color characteristics Average Size Purpose Product from or by the animal Fun Fact

33  Answer the Following  Where did Mike go?  What is his job?  What part of the job is dangerous?  5 facts about ostriches  How do you catch or steer an ostrich and why?  Discuss the video with your partner  Why are ostriches considered poultry?  What products do we use and why?  What was one interesting thing you learned ?

34 Please Follow along with your worksheet provided

35  Label the major parts of poultry anatomy  Explain the purpose of specific anatomical differences in digestion anatomy.  Discuss the general reproductive anatomy of a hen.

36  How are poultry manipulated for production?

37 I think it means….Because of… (clues) We have selectively bred chickens to have large breast meat because this is the cut of meat that brings the most profit. It is actually defined as…Ways to help me remember this/Examples are

38  Breeding for desired characteristics  We have selective bred chickens to have enlarged breasts and grow quickly (7 weeks) to increase profits

39 What do you call a mature male? Rooster What do you call a mature female? Hen What do you call a young female? Pullet What do you call a castrated male? Capon Chickens [Hatch] (they are not “born”)

40

41

42

43  Crop- food storage  Birds are prey animals. Need to “eat and run”  Gizzard- grinds food  Birds don’t have teeth. Gizzard is muscular organ that contains grit (stones) to help grind food  Proventriculus  Secretes digestive enzymes to break down food  Cloaca  Vent when poop and eggs are expelled

44  How are chicken’s (and bird’s in general) digestive systems specialized and different from our own?  Give 3 examples

45

46

47  Hens only lay legs NOT ROOSTERS  Male reproductive organs are located inside the bird  Temperature regulation EXTRA important to prevent infertility  Spaying a chicken = difficult ▪ Therefore: Capons are mainly for religious purposes

48

49  How have birds adapted ?  Hollow bones = light weight  Keeled sternum= lower center of gravity and large bone provide extra large pectoral muscle attachments ▪ WE EAT THE PECTORAL (breast) muscle in chickens!  Fused wrists and bones ▪ Give wings their shape ▪ We EAT the wings. Two types  Drumstick and double bone wing

50  Add these to your list and Define the following words:  Spurs Primary Feathers  CropGizzard  Cloaca

51  Person A  Give the word and the definition  Person B  Use the vocab word in a sentence

52

53  Egg hatching Video  Lm3SK_vRE Lm3SK_vRE

54  Label the basic anatomical parts of the egg, and reproductive system of the hen  Explain the process of gestation within the egg.  Discuss the process of fertilization and egg development.  Understand the importance and purpose of gestation.  Define the process of incubation and its importance.

55  What is an egg?  What parts of an egg do you know?  What do they “do”?  What parts do we eat?

56  Egg- the female germ cell.  The egg becomes the embryo.  Avian egg- bird eggs.

57  It includes the following: ▪ Shell ▪ Shell membranes ▪ Albumen ▪ Yolk  Together they protect and nourish.

58  1.Ovulation- release of mature yolk from the ovary.  2.Infundibulum- receives the yolk, about 15 minutes spent.

59  3.Yolk moves into magnum 50% of albumen is added. Takes 3 hours.  4.Spends 1.5 hours in the Isthmus. Shell membranes added.  5. Total process takes about 24 hours

60  Draw how an egg is formed inside of a hen should be 6 boxes Step OneStep TwoStep Three Step FourStep FiveEgg is LAID! What will the chicken do now?

61 Egg Formation

62  The yellow part of the egg is called the…  The white part of the egg is called the …  What do these do?!?

63 1. Shell- hard outer surface; calcium 1.Shell has pores to allow loss of CO2, moisture.

64 2. Shell membranes- there are two one next to the shell, and surrounding albumen, yolk. a. Known as Inner and Outer Membrane

65 3. Air Cell- air space between two shell membranes. 4. Albumen- egg white. 5. Yolk- true egg, if fertilized become embryo.

66

67 Germinal DISC

68  Mammals:  Young developing within the mother  Mother provides nourishment (milk)  Avian:  Young develop outside the mother (hen)  Mother does not provide nourishment

69  What do you see in this picture? What is happening?  How do you know?

70 How does the yolk sac change throughout gestation?

71 Artificially keeping an egg warm until hatching= incubation Completed in an incubator- artificially heated container. Gestation period: approximately 3 weeks

72 The incubator must be kept at a certain temperature range 99 to 103 F. Eggs must be turned while incubating -Why do we turn eggs during incubation??

73 -Temperature = degrees under light, deg in house -Decrease temp. 5 degrees / week until 60 degrees MUST REGULATE TEMP! -If chicks are huddled together under light = too cold -If none are under light = too hot -Should be scattered -Teach how to drink right away

74  Eggs are great examples of a self sufficient way to raise a young animal. This statement is true because…………  The most interesting part/ adaptation of the egg is the …….

75  Define the following words:  OvumAlbumen  GestationYolk Sac  Incubation

76  Person A  Give the word and the definition  Person B  Use the vocab word in a sentence

77

78  Describe required management practices and their purpose in poultry health.  Evaluate basic parts of poultry nutrition.  Define vaccinations and their purpose within the poultry industry. 

79 -Do not over crowd young or adult birds ALL Birds have a minimum space requirement as highlighted by the USDA EXAMPLE:CHICK-Space requirements:  10 square inches / chick under light  25 square inches / chick house space  Chicks shouldn’t be allowed to get more than 3 ft away from light

80 I think it means….Because of… (clues) Vertical Integration has allowed for the poultry industry to become the most successful food model that has led to other industries attempting to duplicate the business model. It is actually defined as…Ways to help me remember this/Examples are

81  Chicken Management Strategies  Housing and Feeding (Methods)  Nutrition  Biosecurity /Disease Prevention

82  Definition: Several steps in production, from raw materials to final product, are controlled by company or owner.

83 Vertical Integration

84  Debeaking: remove 1/3 of the top beak and a small part of the bottom (prevent cannibalism)  at 6-8 days old  Controversial practice birds per minute. This fast pace sometimes results in inappropriate cuts causing excessive bleeding  Vaccinate (hatchery can do this)  Sprays, shots, eye drops

85

86 Lighting: birds naturally reproduce in spring, simulate spring, chickens molt (shed feathers) production increases

87  Requirements:  Heaters  Radiant =heat the litter and items in the house. Not the air. More efficient  Thermometers  Electronically hooked to emergency back up systems. Regular mercury thermometer for back up  Feeding system  Always filled, but no wasteful spilling  Litter  Low dust, absorbent

88  Requirements Continued:  Humidity  Prevents dusty conditions, heat regulation more effective, decreases stress (too dry = stress)  Watering system  No spilling, sanitary!, monitored with meter  Alarm systems  Prevent unhealthy and stressful conditions  Standby equipment  Ready for power or other emergency, prevents losses (deaths)

89

90  Water: MOST IMPORTANT nutrient  Birds need this to aide in digestion and temperature regulation  Protein  Build muscle quickly  Carbohydrates and fats  Energy  Minerals and Vitamins  proper growth and development  Feed Additives:  Marigold petals: provide yellow tint to chicken skin. Marketed by Perdue chicken as “healthier”. NO health benefits for yellow skinned chicken but public bought in

91 Marek’s Disease: vaccine given in ovo Symptoms include : paralysis, blindness, gasping Infectious bronchitis: caused by a virus. Prevented through vaccination Symptoms include gasping, decreased feed intake, soft egg shells

92 Vaccination methods

93  Security measures taken to prevent the spread of disease

94  Define the following words:  LitterMarek’s disease  Vaccination Biosecurity  Infectious Bronchitis

95

96  What type of management practices do you think are used in this photo?

97  Define vertical integration.  Label major parts of the poultry industry.  Summarize the main processes in poultry product production.

98  How does vertical integration help chicken producers?

99  Over 90% of eggs produced are by layers in cages.  The most common grouping is four hens per cage.  Controversial practice because many birds become over crowded, never spread their wings, and are injured by cage or other birds

100  -Most eggs sold in the U.S. are white.  Produced by what type of bird?  -In large scale commercial operations, lighting is used to stimulate the hormonal activity of the hens to increase their production of eggs.  They produce eggs naturally when the days are longer than the nights.  Most operations allow hours of light per day

101  Collect eggs 2-3 times per day (if hot)  Wash eggs immediately in warm water  Sprayed with protective coding to maintain freshness  Refrigerate  Production Goal: 4 lbs feed / dozen eggs  Hens produce 7 eggs / 10 days

102 -Eggs are coated with a thin coat of mineral oil to prevent carbon dioxide from escaping from within the egg. -Eggs are graded according to size and checked for cracks and interior spots by candling.

103  Market at 4 1/2 lbs for males, 3 1/2 lbs for females (about 8 weeks)  2.1 lbs feed / lb of gain  This rate of gain can cause health issues like “flopping”  Down birds fall under their own weight. Bone structure cannot keep up with weight gain of meat

104  Most are white  Colored birds have pigmentation spots in their skin which is undesirable to the consumer  Kept to certain age, based on weight  ALL IN ALL OUT

105 1. All birds are hatched at same time 2. Grow together at same general rate 3. All sent to slaughter at same time 4. Entire house disinfected and cleaned 5. New “generation” brought in

106 Define the following words: Vertical Integration

107  Draw on a poster with your group a representation on vertical integration.  Label each segment (grain mill, slaughter house etc)

108  Agronomy Sales  Shift supervisor  Seed Production  Grain Operations  Farm Marketer  Feed Mill Manager  Plant Manager Waste Water Supervisor Barn Supervisor unities.html
