Jersey- Originated on Jersey Island- Fawn color- Small to Moderate size: 1500/1000- Strengths: **MILK PRODUCTION:- High milk fat: 4.7%- Value in amount of fat- MODERATE YIELD- Used for processed dairy productsB. Others- 5%1. Brown Swiss: Switzerland2. Guernsey3. Ayrshire: Scotland4. Milking Shorthorn: England*average milk productiona. Crossbreeding: giving up some milk, but reproductively soundII. Swine BreedsA. Maternal Breeds (white breeds)a. Yorkshire: Known as the large white or the mother breed- #1 in US- Originated in England- **LARGE ERECT EARS**- 10-15 Pigs per litterb. Landrace: #4 in US- Originated in Denmark- Ears flop downc. Chester White- Originated in USd. Meishan- Originated in china- Smaller, fatter- Prolificacy (18-22 pigs per litter)**TRAITS WE WANT TO SEE:- Large litter size- Mothering ability- # of pigs per litter- Weaning weight - # of litters per year- Needs to be structurally soundB. Paternal Breeds (colored breeds)a. Duroc: #2 in US- Originated in Spain- Red with BIG, FLOPPY EARS- Known for growth and leannessb. Hampshire: #3 in US- Originated in Kentucky- BLACK WITH WHITE BELT OVER BOTH FRONT LEGS- Erect ears- Muscle and Leannessc. Pietran- Known for MUSCLE- Originated in Belgium- Erect ears- White with black spots- **SUSCEPTIBLE TO STRESS POOR QUALITYd. Spotted- Originated in Indianae. Berkshire: NO REAL VALUE FOR REG. US CITIZENS, ONLY RICH US AND ALL OF JAPAN- Black with white points- Originated in England- Good Export from North US to Japan- Known as the angus of swine because of meat quality (marbling)**TRAITS WE LOOK FOR:- Meat quantity- Fat- Muscling- Growth rate- Feed efficiencyC. Genetic companies select PIC C-22 gilt and PIC 280 Boars which are used in slaughtering… known as terminal breeds** All pigs are going to be made crossbreeds, except for Berkshire.**The Swine Industry has tried SUPER hard to target consumer demands… not so good for pigs.III. Breeds of Farm AnimalsA. Sheepa. Ewe Breeds (medium – fine wool)1. Merino: Originated in France2. Rambouillet: Originated in France, #4 in US3. Romney (medium quality): more textile oriented**Female (merino/rambouillet mix) bred to meat breedsb. Ram Breeds (meat breeds)1. Suffolk: large & tall 2. Dorset: all white originated in England3. Hampshire: Most girth- Wool cap and leggings- Suffolk = #1 in US- Dorset = #2 in US- Hampshire = #3 in US4. Texel- Originated on the coast of the Netherlands - Known for muscle growth- Hair Sheep! = No
