Term
What is livestock production blamed for in connection with environmental issues?
Definition
  • global warming (methane release)
  • Tropical deforestation (hambeurger connection, blaming the U.S. for deforestation)
  • Water and air pollution
Term

According to a this book [Beyond Beef: The Rise and Fall of the Cattle Culture, Jeremy Rifkin, 1992] 1000 lb steer consumes enough water to float a destroyer.

Also claims cattle take up 24% of the land mass.

 

Are these statement true?

Definition

This statement does not take into consideration all of the water that will return to the environment through the steer's urine and thus trys to make a false claim to attack the cattle industry.

 

No

Term
Is the U.S. to blame for deforestation for cattle raising?
Definition

No most deforestation in the tropics is due to social, political, economic pressures of other countries to expand cattle ranching.

 

The U.S. has its own source of beef production within its contentent.

Term
What really causes tropical rain forest deforestation?
Definition
  • Slash and burn agriculture caused by small scale farms (also a source of Carbon Dioxide)
  • increasing human population
Term
What are Climate Change Impacts?
Definition
  • Health (heat related deaths, infectious diseases, air quaility-repiratory illneses)
  • Agriculture (crop yield , irrigation demand, pest managment)
  • Forest (heath, composition and productivity)
  • Water Resources (changes in precipitation, water quality, and water supply)
  • coastal areas (erosion and inundation of coastal lands, cost of protecting vulnerable lands)
  • wild life (loss of diversity, species change shifts)
Term
Examples of climate change impacts on wildlife
Definition

Small animals=shorter hibernation and breeding earlier

larger animals=expanding range, higher altitudes

less adaptation-greater ecosystem distruption

 

polar region=decline in polar bears, reproduction success lower, depleting summer sea-ice a main factor of problem.

 

sea ice is hunting grounds for polar bears and places for seals to nurse thier young in the summer

 

Term
What is the main cause of global warming due to greenhouse gases?
Definition

human activities

 

(industrial revolution, combustion engine, deforestation)

 

  • increased CO2 from burning fossil fuels (oil, coal and natural gases)
  • and harvesting
Term
Theriogenic methane facts
Definition
  • Methane only stays in the atmosphere for 9-12 years vs 100,000 years for CO2 before oxidization to CO2 and Water
  • Since methane produced by livestock comes from plant matter in thier diets, this CO2 is said to be carbon neutral (not exactly)
  • Methane absorbs much more radiation than CO2 but nonetheless its short half life makes it less of a long term concern
  • Current research is attempting to decrease the activity of methanogens in the ruman environment
Term
What are sources of methane?
Definition
  • naural (wet lands, oceans, Termites)
  • Energy (gas, oil, landfills)
  • agriculture (rice, livestock, manure)
Term
What is being done to reduce methan release in anaerobic fermentation of livestock?
Definition
  • lonophore feed additives (reduce emission)
  • High concentrate diets (reduce emission)
  • both (increase growth rate, decrease age to slaughter and thus make smaller life spands reducing methane release over the lifespand of the animal)

forage diets (i.e. fiber) cause more methane release

Term
Why is it important to understand methan's link to Global warming for animal scientists?
Definition
Ruminants release large amounts of methane-serves as a hydrogen sink during rumination. Cows release more than 100 liters of CH4 per day. This is a significant energy loss wich means more $ to support digestion. World-wide ruminants contribute 15-20% of methane animla production may contribute to deforestaton.
Term
Livestock water resources and utilization
Definition
  1. High requirments and low urine concentration (cattle, buffalo, pig, horse)
  2. intermediate requirment, medium urine concentration (warm, dry, semiarid savana animals such as donkey and sheep)
  3. low requirment and high urine concentration (arid climate animals such as goat, camel and ostrich)

poor urine concentration = inefficient

high urine concentration = efficient

Term
What are the effects of animal waste on the environment?
Definition

major concern for excess nutrients with pathogens that cause disease

 

nitrates and phosphorus contaminate ground water cause eutrophiation (water becomes enriched with nutrients that stimulate plant growth and depletes dissoved oxygen)

Term
What can be done to reduce excretion of nitrogen and phosphorus?
Definition
  • feed additives (phytases) -reduces amount excreated by increasing available phyate phosphorus
  • new variety of feed (corn) - reduces phytic acid but increases bioavailability of phosphorus
  • diet formulation-ecological nutrition or precision nutriton (highly digestible protiens, synthetic amino acids, bioavailable phosphous source)
  • novel means-transgenic pigs (segrete salivary phytase - reduce phosphorus secteation)
Term
What can be done to productin animal waste to make it safer and usable?
Definition
  • treat it (bioremediation) neutralization by bacteria
  • burning for energy, or methane production for electricity or fuel
  • use for fertalizer or soil amendment (poultry litter burned to generate power)

compositng done correclty kills pathogens (not feasible for lare scale operations)

care must be taken so waste doesnt make it into water if using as fertilizer

Term
Define global warming...
Definition
general increase in temperature world wide thought to be associated with human activity

Term
Managing livestock in developing countries
Definition
  • Alley cropping (rows of trees with rows of crops) trees provide shade from tropical sun, livestock reduce weed pressure.
  • fast growing trees
  • leguminous trees (leucaena leucocephala) in the tropic have an added bonus of fixing N2
  • integrate livestock into stables (benefit farmers and wildlife)
  • Cut and Carry System (tropics) protects delicate pasture/forest environments (livestock are brough cut grass in pens)
Term
Jully 7, 2001 the Humane Society of the United States and the United Egg Producers announced what, and why was it a sock?
Definition

They were working togethere toward the enactment of comprehensive new federal legisation for egg laying hens.

 

This is stunning because generally animal industries and animal protection agencies generally dont get along.

compromise would focus on

cage size, labeling requirements, regulation other production practices

HSUS agreed to suspend state-level initiatives in OR and WA

Term
What are the major claims about "factory farming" that Prop 2 in California tried to fix?
Definition
  • Prevent cruelty under the assumption that farmers dont care about their animals
  • Better food saftey under the assumption that slaughterhouse cruelty puts consumers at risk and creates disease
  • Supports family farmers under the assumption that big farms cut corners and puts small farms out of business
  • Protects the environment under the assumption that it will protect natural resources
Term

What are the arguments against Prop 2 and how could it actually be harmful?

 

(this was passed in CA)

Definition
  • it is unnecessary since CA law already protects these animals
  • Causes more risks of contracting Avian influenza, salmella and other diseases with open range systems
  • harms the consumer by causing higher prices, costing 1000 jobs, and causing economic loss (95% business loss by 2015 and production increase of 76%)

(prevents mastisis)

AVMA doesnt think there is a link between the two

may just be for human comfort

 

alternatives

(trim switch, dry housing/bedding)

most U.S. cattle are fed an unnatural diet of corn when grass would be more natural

Definition

Fiction

  • most U.S. beef comes from pasture-fed grain-finished cattle
  • recieve feed rations nutritionally balanced
  • veterinarians monitor cattle health and well-being
  • feeding grain-based ration for shor-time--better meat quality and product for consumer
  • (cattle are feed corn with other roughage needed for digestion/ cattle and deer enjory when they can get it
Term
What are feed additives?
Definition

non-nutritive substances added to feeds to improve

  • influence feed stability, feed manufacturing (mold inhibitors, pellet binders, antioxidants)
  • modify Fi, digestion, growth, feed efficiency, metabolism(feed flavors, digestive/metabolic modifers, growth promotors)
  • modify animal health (drugs, enironmentally active substances)
  • Modify consumer acceptance (pigmenting agents)

(NOT: synthetic aa, vitamins, minerals)

 

Term
Corn cannot be fed whole to animals and must be ground. What problem does this cause and how is it fixed?
Definition

when oil is exposed to air in crushing, a Rancid smell is created and nutrition and palatability is decreased.

 

To prevent this antioxidant feed attitives are used (natural are Vit E and C but they are expensive so levels of syntheic ones that are approved by the FDA are used.

 

Also mold inhibitors (Mycotoin)

Pellet binders (more food in smaller space)

Definition
  • animal welfare, feeding and nutrition programs are often better due to resources and monitoring and control
  • pollution-afford sophisticated systems-ensure less air and water pollution
  • product quality-total control of genetic, nutrition, health programs=produce more consistent and uniform, high quality products
  • worker benefits

(some states have legislation prohibiting coroprate farming - development/expansion-)

Term

  • political gerrymandering (creates climate suitable for corporate farm development
Term
What is the deal with Sweden?
Definition

it is going back to the "good old days"

it was hardest hit by gestation stalls

Since the government controls are aspects of animal agriculture, even down to what the animals can be used for, they created new legislatin preventing the use of antibiotics

Term
define a feral animal
Definition
  • animals which were once domestic but since reverted back to a state of nature are termed "feral" wild by nature, especially based on behavior.
Term

Consequences of feral animals

 

Definition

*not all invasivew mammal species casue problems*

  • predation and competition
  • Extirpation (destroy totally) native species
  • soil disturbances and land degration (ruin watering holes that wildlife uses, destroy parks, gol courses,athletic fields, eat agricultural crops)
  • nutrient recycling
  • water quality deterioration
  • disease transmission vector to livestock, wildlife and humans (some of these disease were eradicated and are now showing up agian)
Term
Cumberland Island
Definition

Feral horse problem!

 

--grazing preferecne smooth cord grasses (found in tidal areas and functions as protection from storms) this leads to erosion problems

--eat sponish moss that is vital for amphibians, sea turtle nesting and brooding birds

--unlike cow, horses trample vegetation and over graze causing soil to be hard-packed

--force bighorn sheep out of area and away from water sources

--graze in higher elevations than cattle normally would

 

FERAL Hogs

--disrupts nutrient recycling, eat vegetaion important to invertebrates (insects, worms, turtles, etc.) eat eggs

 

Term
Feral horses in Australia
Definition
  • around 400,000 horses and millions of donkeys
  • occur in extensive cattle productions (drawn to cattle resources)
  • eat pasture grasses, destroy fences, casue cattle to scatter, cary exotic diseases)

destroy drought areas much faster

Term
What is the most destructive invasive species in the U.S.?
Definition

Wild Hogs

  • Hogs brought from Europe and Asia
  • Colombus brought them to the Caribbean, and De Soto brought them to Florida
  • they kill fish
  • make it easier for inasive plants to take hold
  • can eat lambs, deer and quail depending on the case
  • eat eggs
Term
Why are Feral Pigs so invasive?
Definition
  • adapt to almost any condition, climate or ecosystem (live in all of Texa's varing ecosystems)
  • Intelligent animals (evade trapping)
  • Have no natural predators
  • Prolific breeders (if reduced by 70% within 2 or 3 years the numbers would be just as high as before)
  • breed at 6 to 8 months and live to 4 or 8 years
  • two litters per year with 8-12 piglets each litter
  • opportunistic omnivores (snout strenghtend by and end plate of cartlige)
Term
What are some management strategies or control programs for wild Hogs?
Definition
  • Lethal means: (intensive harvesting, snares, poisoning, traps, sterilization, slaughter [danger to other wildlife]
  • Non-leathal means: exclusion of feral pigs from areas prone to damage (fening) [expensive and not useful in large areas]

problem once a pig servives a means of extermination it is smarter and will avoid the same method

Term
Differences between wild and domestic pigs...
Definition
  • wild are smaller and have narrower skulls due to less nutrition
  • wild have curved tusks up to 7in and an elongated snout
  • wild have thick brisk hair and dark skin
  • sexually mature males develop shields (thick 2inch hard tissue on sholders)
  • females roam in groups males remain solitary
  • nocternal

Escaped pigs change quickly

Term
Humans and wild pigs, the cause and use...
Definition
  • seen as a game species and illegal translocation has contributed to the large population of feral hogs around the U.S.
  • escaped pigs from farms
  • Used as Exotic meat (not gamy or greasy) pigs must be alive and then processed in a plant overseen by a USDA inspector
  • Most meat sent to Europe and Southeast Asia
  • American market growing
Term

according to lean percentages

some also labeled according to portion derived from (ground chuck, round, siroin)

Term
What is Lean Finely Textured beef?
Definition

beef product developed by Beef Products, Inc. (BPI) in 1991 to provide more domestic lean beef

 

trimmings are heated to 100F and centrifuged, separating fat from meat (94 to 97% lean beef)

 

there is the additonal developed process of using ammonium gas as a antimicrobial intervention (pH enhancement)

Aproved by USDA 2001 following an E coli scare with undercooked hambergures

effectively kills both E coli and salmonells (its an antimicrobial)

Term
How is lean beef taken from trim that is used mainly for hamburgers?
Definition
  1. trim (part of carcass that is left after specifec "cuts" of meat are cut) has a high fat content
  2. 95% lean (beef is separated from fat)
  3. Add food-grade ammonia gas (mixed with water creates ammonium hydroxxide which rizes the pH level in LFTB and kills pathogens.
  4. quickly frozen and packaged
  5. Combine LFTB with beef trimmings = ground beef
Term
What is the purpose of ammonium hydroxide in LFTB?
Definition

Kills alot f the harmful bacteria that could be present

 

this practice was approved over 20 years ago

 

IN GAS FOR NOT LIQUID HOUSE CLEANER

Term
The fallout from the LFTB controversy...
Definition
  • USDA gave school districs the choice between ground beef with or without LFTB
  • Retailers halted use of LFTB prior to some fast food chains
  • Kroger originally banned then gave consumer feedback
  • Whole foods and Costco claimed they never bought the stuff
  • Walmart gave consumers the choice
  • BPI cut LFTB production
  • Ground beef prices rise
  • more beef imported from Austraila and New Zealand
  • packers lost more than $100 per head then producers lost
Term
Labels for LFTB...
Definition

April 2 2012 USDA confirmed some companies requested LFTB be added to labels on ground beef

 

  • approved
  • voluntary lable
  • USKA certify labels are correct
  • LFTB not included in required ingrediant lable
