Current welfare issues in beef cattle Flashcards
What is considered an animal welfare issue?
- Includes basic health and functioning, affective states and natural living
- We often focus mostly on basic health and functioning and neglect the other two
- There is a lack of perspective on what other stakeholders may consider a problem
Consumer disconnect from production practices
- There is often a lack of understanding by consumers who claim to be knowledgeable or interested in the topic of food production
- Most concerning were the misconceptions about beef life cycle and how cattle are produced (ex. cattle raised quickly and fed cheaply, pumped with hormones and antibiotics that transfer to the meat we eat
What is the top concerns on production practices?
- Animal welfare (29%)
- Animal diet (9%)
- Hormones
- Environmental impact (5%)
- Antibiotic usage (4%)
- Meat quality and safety (2%)
- Other (2%)
43% of responders to survey did not have any concerns
Folk conceptions of welfare (non-expert people’s opinions)
- Provision of choice (eg. Shade, cafeteria-style diets)
- Give the animal the option to choose - Longevity, killing of young animals
- For good meat, need to slaughter very young. Not easy to get around this. - Wasteful death (eg. Mass populations)
- Not good for vet, producers, public, animal. The most we can do is provide good care, vaccines, and biosecurity to try and prevent this. - Aesthetics of methods of killing (eg. Effective stunning/bleeding)
- All about efficiency and doing it without suffering - Aesthetics of the animal, and their environment (eg. Stocking density, transport)
- How consumers think an animal should be raised compared to what they think they see
- Related to ensuring animal has the right amount of space, resting time, etc. - Human kindness/stockmanship (eg. Health management, painful procedures)
- Need to ensure they have proper handling, correct procedures, and vaccines
Welfare concern- transportation
Often the only time the general public get to see animals used in agriculture
- Too hot and cold
- Clean or dirty
- Looks like little space
Animals can actually spend quite a lot of time be transported. Transport to pasture, farm, auction, feedlot, slaughter, fairs, other farms
There are important public and trade concerns worldwide
Transport stressful events
- Unfamiliar sounds
- Unpredictable motions (stop-starts, turns)
- Temperature
- Water and feed restriction
- Handling during loading and unloading- Can be difficult to have the low stress handling because could be rushed and animals often are very opposed to going inside
- Crowding, commingling
- Issues related to cull cows
Temperature at animal level in truck experiment
Put temperature sensors (animal level, ceiling, truck)
- Most of the time, temperature level at animal level during winter was in the thermoneutral zone (good)
- During the summer, often temperature levels were too high at the animal level
Loss of body weight and transport
- Transport duration and ambient temperatures have a multiplicative effect on each other
- Higher temperature, more time in transport= Body weight shrinkage
- Differs based on feeder cattle, calves, and cull cattle (need to add ~1-4% more shrinkage)
Animal health and time in truck
After 30hrs, large increase in lame, downers, and dead cattle
Animal health and temperature
- Higher temperatures= increase in downer cattle
- Lower temperatures= increase in dead cows
Looking at cattle transport fitness on arrival at auctions
3 categories (fit, compromised, unfit)
- After long hours in the trailer, more than 90% of cattle were in fit condition when going to auction or federal abattoir
- Poorest conditions found at provincial abattoir (lameness, injuries, lactation)- makes sense because these animals would only be allowed to go short distances
Effect of rest stop duration during long-distance transport on welfare indicators (weaned beef calves)
- Now: Can go 36 hours before needing rest
- Rest time of 8hours to 12 hours did not seem to change the results therefore rest stop length have no consistent effect on welfare indicators
How conditioning to travel, source and rest effects stress in beef cattle transport
- Rest did not have significant difference in animal welfare
- Source: auction or ranch did not have an effect on animal welfare
- Conditioned vs. unconditioned cattle showed an effect on animal welfare. When unconditioned, poor animal welfare was a result from transport.
Conditioned vs unconditioned animal and its effects on animal welfare
Unconditioned animals had increases in fat breakdown (NEFA), inflammation (SAA and Hapatoglobin), muscle damage (CK), and discomfort (standing time)
Poor Stocking density risks
Close proximity to other animals, human infrastructure and human handling may increase the incidence of stress-mediated diseases (eg. BRD)
Highly populated pens may impact feed consumption patterns, with potential implications on gut health (eg. Acidosis), feed efficiency, growth performance, and carcass value (eg. Marbling sore and liver abscesses)
