Cattle
Welfare: During Transportation
By Maureen Zorn – Dairy Associate
Loading cattle on
a trailer is something that most farmers do on a regular basis. People
think about trailering as a normal, everyday occurrence, but the picture
looks a whole lot different from the cow’s point of view. To the
cow, it doesn’t matter why she’s getting on the truck. She
could be going to a show, going out to pasture, going to a heifer grower
or going to slaughter.
No matter the reason, trailering is still a scary event most of the time.
Most people realize that trailering is stressful for animals and sometimes
for the people involved. Because of the stress involved in trailering,
animal welfare is an issue as well as economic losses. In addressing these
bottom-line concerns, handlers can eliminate unnecessary stress and thus
improve welfare during transportation.
Bruising Happens
The major issue that producers must consider is economic losses during
transportation. Certainly for beef producers this is an important issue,
but dairy producers are also affected by meat quality losses. In 1999,
22% of cull cows had severe bruising. Stress and bruising leads to meat
quality problems, (like dark circles) which cost the beef industry $6.08
for every animal slaughtered. Furthermore, shipping fever costs $624 million
per year (dairy and beef industries). Clearly, there is plenty of room
for improvement in these statistics.
To minimize economic losses, animal welfare during transportation needs
to be improved. To make improvement, it is essential for handlers, cattle
haulers and producers to understand the underlying conditions that cause
stress during transportation. Some of the big picture issues of transportation
are: duration of journey, novelty, vibration, shocks and impacts, noise,
and orientation. Other more specific issues include: ventilation, loading,
temperature, stocking density, location in vehicle, lack of food and water,
breaks during journey, and mixing.
Check Loading Conditions
When loading cattle onto a trailer, handlers need to recognize the kinds
of objects, lighting and noises that spook cattle. Cattle prefer good
lighting and will move more naturally into well-lit areas. Thus, trailers
should not look like a dark hole to cattle. Cattle handlers also need
to be careful of shadows when loading animals. This is why it’s
preferable to use solid panels in a loading chute if possible. Another
important consideration is footing when loading cattle. Ensure that surfaces
are non-slip and put down “barn-dry” or another non-slip agent
if necessary. Changes in flooring surface, (such as concrete to gravel)
could also cause cattle to balk. Cattle prods, sticks, etc. should not
be used on animals.
Experienced cattle handlers know the signs of anxiety and fear. In cattle,
these are generally easy to recognize. Tail swishing is an obvious sign
of stress and the speed increases as the fear or stress increases. Sweating
when there has been little exertion is an obvious sign of stress. An animal
with her head up who is vigilant and looking around, or an animal with
her ears pointed directly at an object may be concerned in certain situations.
Also important to remember is that novelty is a strong stressor. In any
new or different situation, animals will experience some stress.
Stocking density is a contributing factor to the amount of stress and
injuries cattle experience during transportation. Animals should be able
to stand in a natural position on the trailer in order to maintain their
balance. The idea that animals are protected by being packed in is erroneous.
The effect of stocking density is shown by higher blood cortisol levels
in trailers with a higher stocking density. Animals should be fit so that
they are close to each other, but not “packed”. The driver
also has an effect on the welfare of the animals. A carefully driven vehicle
with no sudden braking or acceleration will deliver animals that are less-stressed.
The type of trailering system used to haul animals can make a big difference.
Animals experience fewer bruises with doors that open to the full width
of the trailer for unloading. Pneumatic suspension is generally better
than leaf springs, and articulated vehicles tend to be better than rigid
vehicles. Also, be sure that tires are not over-inflated and that plenty
of bedding is used.
Lastly, use common sense when transporting animals. Heat builds up in
stationary vehicles. Make sure to park in the shade if possible when stopped.
Stocking density needs to be decreased in hot weather. As producers, you
may already be aware of such things. However, it’s your responsibility
to ensure your cattle get to their final destination with minimal stress
involved.
