14 Objective Analyze the various breeds of beef, swine and poultry as related to use and the economic value of each Analyze the various breeds of beef, swine and poultry as related to use and the economic value of each

15 Beef Breeds English Breeds (European, Bos taurus) English Breeds (European, Bos taurus) Angus- black breed with excellent meat quality Angus- black breed with excellent meat quality Hereford- red with a white face Hereford- red with a white face Shorthorn- used in the bloodline of more than 30 other breeds Shorthorn- used in the bloodline of more than 30 other breeds

16 Angus

17 Beef Breeds Exotic Breeds (India, Bos indicus) Exotic Breeds (India, Bos indicus) Grow faster than English breeds Grow faster than English breeds Leaner meat Leaner meat Brahman, BeefMaster, Brangus Brahman, BeefMaster, Brangus

18 Brahman

19 Beef Breeds Breeds in America have been developed by crossing (breeding) English and Exotic Breeds from India Breeds in America have been developed by crossing (breeding) English and Exotic Breeds from India Resulted in: Resulted in: Increased heat tolerance Increased heat tolerance Parasite (worms, lice) resistance Parasite (worms, lice) resistance Resist disease Resist disease

20 Dairy Breeds Holstein Holstein 90% of the dairy cattle in the US 90% of the dairy cattle in the US Black and white Black and white Leading producer of milk Leading producer of milk Produce about 18,000 lbs. Of milk per cow per year Produce about 18,000 lbs. Of milk per cow per year

21 Dairy Breeds Other Breeds Other Breeds Guernsey- fawn and white Guernsey- fawn and white Jersey- cream to light fawn to almost black Jersey- cream to light fawn to almost black Number one in milk fat Number one in milk fat Ayrshire-cherry red and white Ayrshire-cherry red and white Brown Swiss- solid brown Brown Swiss- solid brown

33 Swine Industry Purebred producers produce high quality boars: Purebred producers produce high quality boars: Improves the genetic make-up Improves the genetic make-up Purebreds are crossed with regular sows to increase hybrid vigor Purebreds are crossed with regular sows to increase hybrid vigor

34 Poultry Production Classified as: Classified as: Broilers Broilers Layers Layers egg producers egg producers White Leghorn are used mostly for egg production White Leghorn are used mostly for egg production

35 White Leghorn Rooster

36 Poultry Industry Another Class of Chicken is the Bantam Another Class of Chicken is the Bantam Miniature versions of standard breeds Miniature versions of standard breeds Primarily for show Primarily for show 90% of the turkeys grown are broad breasted whites 90% of the turkeys grown are broad breasted whites

37 Poultry Industry Dutch Bantam Chicken

38 Pop-Quiz 1. Provide an explanation for the term farrow. 2. What is the breed of cattle that leads in milk production? 3. What breed of cattle is know for producing the most milk fat? 4. What is the most common breed of laying chicken? 5. Describe the term hybrid vigor.

39 Animal Nutrition Objective: Determine the nutritional requirements for livestock and poultry breeds found in North Carolina

40 Major Nutrients Water Water Protein Protein Carbohydrates Carbohydrates Minerals Minerals Vitamins Vitamins Fats and Oils Fats and Oils

41 Water Largest component of all living things Largest component of all living things Animals tissue is about 75% Animals tissue is about 75% Regulates body temperature Regulates body temperature Perspiration Perspiration Transports nutrients Transports nutrients Involved in all biochemical reactions Involved in all biochemical reactions

42 Proteins Major component of muscles and tissues Major component of muscles and tissues Made up of amino acids Made up of amino acids Continuously needed to replace dying body cells Continuously needed to replace dying body cells Young animals need large amounts for growth Young animals need large amounts for growth

43 Carbohydrates Composed of sugar and starches Composed of sugar and starches Provide energy and heat Provide energy and heat Make up 75% of most animal rations Make up 75% of most animal rations Main source: Main source: Corn Corn Cereal grains Cereal grains

44 Minerals 15 essential minerals: 15 essential minerals: Calcium, phosphorus, sodium, etc. Calcium, phosphorus, sodium, etc. Example: calcium is needed in poultry for eggshell development Example: calcium is needed in poultry for eggshell development Minerals are supplied by: Minerals are supplied by: Naturally Naturally Mineral supplements Mineral supplements Mineral (lick) blocks Mineral (lick) blocks

45 Vitamins Needed in small quantities Needed in small quantities Need for vitamins varies from species to species Need for vitamins varies from species to species Sources: Sources: Naturally found in feed Naturally found in feed Feed additives made from animal by- products Feed additives made from animal by- products Made by the body itself Made by the body itself

46 Fats and Oils Only needed in small amounts Only needed in small amounts Improves: Improves: Flavor Flavor Palatability Palatability Texture Texture Increases fattening and milk production Increases fattening and milk production Carriers of some vitamins Carriers of some vitamins

47 Classes of Feed Concentrates Concentrates Low in fiber Low in fiber Cereal grains Cereal grains Animal and Plant by-products Animal and Plant by-products Roughages (high fiber) Roughages (high fiber) Dry roughage is hay Dry roughage is hay Green roughage includes pastures Green roughage includes pastures Silage is roughage fermented from green chop Silage is roughage fermented from green chop

48 TDN Total Digestible Nutrients Total Digestible Nutrients Concentrates are high in TDN Roughages are low in TDN

49 Assignment Read pages 484 to 499 Read pages 484 to 499 Complete Self Evaluation page 499 and page 500 Complete Self Evaluation page 499 and page 500 Complete both section A and B Complete both section A and B

50 Animal Digestive Systems Objective: Compare animal digestive systems of beef, swine, and poultry

51 Ruminants Ruminant Digestive System

52 Ruminants Cattle, sheep, goats, deer Cattle, sheep, goats, deer Four compartments to their stomach Four compartments to their stomach Can eat more roughage in their diet Can eat more roughage in their diet Grass Grass Hay Hay Silage Silage Green Chop Green Chop

53 Monogastric Simple Digestive System

54 Monogastric Swine, horses, rabbits, humans Swine, horses, rabbits, humans Stomach has one compartment Stomach has one compartment Rations must be high in concentrates Rations must be high in concentrates Grains Grains Corn Corn Animals can not digest large amounts of fiber or roughage Animals can not digest large amounts of fiber or roughage

55 Poultry Chickens Chickens Turkeys Turkeys Ducks Ducks Geese Geese

56 Poultry No true stomach No true stomach Can not store large amounts of food Can not store large amounts of food Birds do not have teeth for chewing Birds do not have teeth for chewing Food is swallowed whole Food is swallowed whole Stored in crop Stored in crop Ground up in the gizzard Ground up in the gizzard

57 Pop Quiz 1. Provide an explanation for the term farrow. 2. What is the breed of cattle that leads in milk production? 3. What breed of cattle is know for producing the most milk fat? 4. What is the most common breed of laying chicken? 5. Describe the term hybrid vigor.

58 Pop Quiz 6. What nutrient is responsible for muscle growth? 7. What nutrient makes up 75% of most animals body? 8. What nutrient is made of sugar and starches? 9. What nutrient carries fat soluble vitamins? 10. What type of animal has four compartments to its stomach.
