Summer is a time when your animals spend most of their time grazing. Summer is also a time when your cattle herd can face health issues. On this blog we will discuss some of the common health issues that your cattle herd might face during summer.

Summer is typically a time for cattle farmers to graze their herd on pastures. It’s also a time when cows and calves may experience health issues.  If you are well prepared before health issues become a serious problem for your herd, you could be saving yourself from serious economic losses.

When you have a large farm, it becomes difficult to monitor the health issues of individual animals, so you should keep in mind the types of diseases that might affect the health of your herd during the summer seasons. Below are some common issues that you need to check and make sure that your cattle herd is in good shape.

Weather related health hazards

Summer weather, especially, heat, rain, and storms could become a health hazard for your cattle herd. Dealing with Mother Nature’s wrath could become a challenge if you are not prepared for them. Below are a few of the weather issues that you should be prepared for.

Tornadoes and high winds

Strong winds and tornadoes can destroy structures, pick up debris and drop them in unexpected places. Debris could damage your pasture lands, animal sheds, and pens. After a severe storm, inspect your pastures for any harmful debris. Comb through your grazing areas and look for hazardous objects especially metal objects, nails, wires and such. These could be dangerous for your animals if ingested or stepped on.


A flooded pasture is also dangerous for livestock. Stagnant water exposes livestock to infection by parasites, bacterial diseases, such as blackleg a soil-borne bacterium infection, and fungal infections such as hoof rot. Stagnant water is also harmful for your pasture plants, drowning their roots and rotting vegetative growth.


Lighting is one of the major causes of farm fires. “Lightning also is responsible for more than 80 percent of all livestock losses due to accidents and millions of dollars in damage to farm buildings and equipment annually, “ says Farm and Ranch Guide. A lone tree in the middle of the pasture may provide shelter for livestock but it is also more likely to get hit by lightning during a thunderstorm resulting in loss or injury of cattle. Lighting damage can be prevented by using proper Lightning Protection systems.

Summer heat

Hot and dry weather in summer could cause heat stress for your cattle herd. High heat, humidity and lack of wind will affect your cattle health in many ways.  Make sure you have enough room and air circulation in their holding pens or barns and enough cool water and shade during the day.
