Summer 2013 Reminders



Summer is finally here, and temperature and humidity have increased dramatically over the last month. Animals are beginning to suffer from heat stress and cool-season grasses are starting to decrease in productivity. There are certain precautions that need to be taken to manage your grazing system during times of high heat. Keep these key management practices in mind as the weather continues to get hotter to maintain healthy animals and a healthy stand of forage.



“Pinkeye is a tremendous summertime headache in Kentucky. The two most important contributing factors to pinkeye are UV light (sunlight) and face flies. Other risk factors that may contribute to an infection include dust, trauma or injury, wind, tall grass, thick stemmed hay, high ammonia levels and stress. The keys to prevention of an outbreak are maximizing your herd’s immune status through good nutrition and a sound vaccination program, minimizing the spread of the pinkeye bacteria with prompt treatment of clinical cases, and maintaining an irritant-free environment as much as possible.”
