AS an owner or manager of livestock, it’s crucial to protect your animals from harsh weather conditions.
Providing access to shelter can improve animal welfare by reducing the risk of heat stress and production losses because the animal doesn’t have to actively use energy to lower its body temperature.
Agriculture Victoria animal health officer Flick Searle said behavioural signs of heat stress in livestock can include increased respiration rate, panting, increased salivation, listlessness and lethargy.
“Heat stress can be treated by moving affected livestock into shade and providing clean, cool water. If after a period of time, after providing this treatment the animal doesn’t improve, contact a veterinarian immediately or humanely euthanase the animal,” Ms Searle says.
“In high temperatures, the accessible shelter needs to give protection from the sun, reducing solar radiation and also allow air movement,” she says.
“Good examples include trees with large canopies, shade cloth structures and sheds with open sides.
“Farmers need to keep in mind that some livestock have a higher need for shelter, such as very young, old or sick livestock, as their ability to regulate their temperature is reduced.
“Therefore it’s your responsibility to provide care accordingly.”
Ms Searle says when temperatures are high, livestock can tend to crowd shelter areas so it’s vital to have sufficient shelter for all livestock.
“If the shelter is overcrowded, it can have the opposite effect and lead to livestock bunching up and transferring more heat to one another or even result in smothering,” she says.
“The most important things you can do for your animals in hot weather is to provide them with shade, water and rest during the hottest parts of the day.”
