Often, when considering the prevention and
treatment of sunburn
, we neglect to realize that our livestock is as vulnerable to the sun's harsh rays as are we. While cows sunburn less easily than do we, it is still possible and must be treated. Below are some ways in which this may be done.
As is true for humans, it is important to leave the sun immediately upon noticing the onset of a burn. This may be more difficult to spot due to your cow's coat, but sunburn on noses, ears or other more exposed areas is usually more easily noticed. Ensure that your cattle have a shaded area in which to move during hot parts of the day. The shaded area should include both open space and an enclosed area so livestock can both enter by choice and be caged while recovering from burns.
Dehydration often sets in shortly after a sunburn
, so the shaded area should include a plentiful supply of water. It may be best to place your cattle's main water supply in a shaded area, thus requiring them to seek shade throughout the day in order to drink. This also lessens wasteful evaporation caused by exposing water to direct sunlight.
Other remedies that apply to humans are equally applicable when cows sunburn. If the burn is near an eye, it is probably best to let nature run its course rather than risking infection due to non-sterile application procedures. Apply aloe vera extract to the burned areas as frequently as possible. Also, while lessening pain may not have immediately obvious benefits, pain increases stress, which minimizes energy available for other processes such as milk production. Help lessen this by administering painkillers, and by applying a cool and moist cloth to the burned tissue as frequently as possible.
Since cattle lack the ability to make decisions and judgment calls, taking preventative measures is much better by far than is treating a burn after the fact. Here are a few factors of which to be aware when adopting a strategy to prevent cows sunburn.
First, take your cow's skin tone into account. Lighter skinned breeds such as Holsteins tend to burn more easily and warrant special consideration and observation.
Next, if your routine involves access to pastures for grazing, do this during times when sunlight is less direct. UV rays are most present from 10:00 A.M. until about 4:00 P.M., so by permitting grazing outside of these times, the risk of sunburn is minimized.
Also, be aware of what your cattle are eating, as grazing on weeds and young wheat increases cattle's likelihood of burning. Weeds are generally not nutritious and should not be present in your cow's diet. As wheat ages, the compounds that increase a cow's photosensitivity go away, and the increased likelihood of sunburn is lessened if cattle graze on wheat that is slightly yellowed.
Healthy, happy livestock are more productive than are those suffering from disease or other injury. Acting to prevent cows sunburn is an important and often overlooked aspect of overall agricultural health.
