SWINE
- Swine Industry
- Breed Terminology
- Sow- mature female pig
- Boar- mature male
- Gilt- young female
- Barrow- young, castrated male
- Pig/piglet- young swine
- Fourth biggest in food animal agriculture
- Purpose of:
- Use surplus grains
- Produce meat
- Add value to grains
- Efficient digestive system
- Require high energy feeds
- Stages of production
- Feeder pig production (farrowing to weaning)
- Farrowing herd
- Produces a Feeder pig
- 40 pounds, 8 weeks, weaned
- Breeder herd
- Sows and boars
- Farrowing facility
- Breeding/gestation facility
- Baby Pigs
- Nursery
- High fuel cost; must be warm
- Finisher
- Feeder pig to finishing pig
- 220-240 lbs; 5 months
- Large amount of feed; produces large amounts of manure
- Farrow-to-Finish Producer
- Keeps pigs from farrowing to finishing
- Integrated Corporate Production: Have own seedstock
- Seedstock Producers
- Sells breeding stock or show stock
- Which structure used
- Determined by resources
- Fewer, larger farms
- Confinement Production-
- Breeds
- Swine Breeds- used for carcass type
- Lard Type
- Used for lard
- Not important anymore, rarely used
- Very fatty

- White pig
- Crossbreeding Programs
- All market hogs
- Heterosis
- Factors
- Size of herd- multiple or single crossbreeds
- Availability of replacements- young females to add to your breeding herd; buying them is ideal- only maternal traits in bred ones
- Three breed rotation- produce market and breeding stock
- Reproductive Management
- New gilts brought in frequently
- Sows produce ample milk for litter
- Easy to synchronize heat
- All-in-all-out process
- A.I.
- Genetically superior boars
- Semen needs to be fresh
- Challenges of pig farming
- Behavior- intelligent; can escape from pens; dominance hierarchy; long memories
- High reproductive rate- large litters b/c naturally high mortality rates
- Managing nutrition
- Herd health and biosecurity- large # of animals in one space
- Waste disposal
- Health myths- associated w/ high fats, etc.
HORSES
- Industry
- Purpose
- Contribute quality to lives

- Coat colors
- Points- can be different than body color
- Legs, mane, tail
- Modifier genes
- Influences the 3 main coat colors
- Bay- brown w/ black points
- Black
- Chestnut- reddish-color, points same color as the body
- Genetics
- Gene G
- Grey horses
- Usually grey as they age
- Gene E
- Controls presence or absence of black hair on either body or points
- Gene A
- Controls distribution of black hair- if horse is bay OR black
- Gene A restricts black to points, aa causes no restriction
- Gene W
- Unable to form pigment; leads to white horse
- Diluting Gene C
- Cream horse
- Gene C is chestnut
- Gene D

DAIRY
- Dairy Industry
- Third biggest industry
- Purpose
- Make use of resources humans can't
- Forages, food by-products
- Produce food efficiently
- Structure and Location
- Trend toward fewer, larger operations
- Western US
- More milk being produced
- Dairies
- Family Herds
- 50-200 cows
- Most common
- Large, specialized herds
- 200+ to 10,000 cows

- Collects and processes info; determines profitability; management, production, and cost
- Comprehensive management tool
- Breeding
- Milk
- 1 calf/cow/year
- Healthy (dam maintain weight, get healthy before calving)
- Mobility/hoof care
- Handling
- Longevity
- Gestation- 285 days
- Dry period- 60 days
- 20 days to impregnate
- Reproductive Challenges
- Delayed breeding
- Caused by poor nutrition
- Heat detection

- Use aids to tell (patches, transmitters, crayons)
- Breeds
- Holstein- most milk
- Jersey- high level of milk components
- Milk Production
- Peak yield at 2 months, then slowly declines until 305 days
- Persistency- how well milk production is maintained after peak
- Nutrition
- Feed is 45-65% of cost
- High quality feeds
- Dependence on concentrated feeds- cereal grains; high energy levels
- Negative energy balance in mother is a concern (putting out more nutrients than she is taking in)- causes body weight drop
- Feeding systems
- Pasture
- Graze on high-quality pasture, fed concentrate at different time
- Dry-Lot system
- TMR- Total mixed ration- pasture and energy grains are mixed
- Kept in confinement facilities
- Pros: No parlor grain feeding; more control over feed; labor is less for feeding total herd; housing cost is less
- Cons: Special equipment; cows have to be grouped by production levels
- Herd Health
- Mastitis
- Bacterial inflammation of the udder (bacteria enter from outside environment)
- Decreases quality and quantity of milk
- Caused by poor sanitation, faulty milking, etc.
- Milking Parlors
- Machine- pulsating suction
- Types of parlors
- Calf Hutches
- Keep disease from spreading
- Prevent injury from suckling instinct

ANIMAL WELFARE
- Use of technology
- Changed society
- Efficiency improved
- Unaware of modern agrarian ethic
- Period of Activism
- Animal Rights Movement
- Philosophy, sociology, public policy
- Standing of animals in relation to humans
- New Animal Ethic
- Human Nature is protected by legal fences
- Bill of Rights
- Protects against suppression on individual interests
- The question- do animals have natures?
- Basis for society's def. of farm animal's natures
- Anthropomorphism, children's stories, cartoons, movies, notion of family farm, etc.
- Animal's wants vs. animal's needs
- Anthropomorphism
- Does a pig that has never seen a wallow want one?
- Are animals natures the same as human natures?
- New Notion of Animal Rights
- Animals have natures, although they are different than human natures
- Does not mean humans cannot use animals
- Animal use must respect animal's basic natures
- Not extremist
- Welfare (trade-offs, basic needs, human care)
- Rights (no trade-offs, abolitionists, vegans)
- Defining Animal Welfare
- Production of animal is not always a measure of individual well-being
- Physiological measures
- Blood parameters, hormones
- Behavioral measures
- Abnormal behavior, preference tests
- Psychological well-being
- No scientific information
- NEEDS WORK AND RESEARCH ASAP
