FEED•LOT June 2018 11 Identify the Fly One of the first steps in effective fly control is identifying the type of fly, says Larry Hawkins, DVM, Se- nior Technical Service Veterinarian with Bayer Animal Health. "When you're at a feed yard and get out of the truck to talk to someone, or maybe roll your window down for a few minutes, the next thing you know there are 100 files in your truck. For the most part, those will be house flies, or possibly stable flies," he said. Selecting a product for those types of flies is important. The biggest issue with house flies is as a nuisance. No one – including neighbors – likes them, and they have been known to carry bacteria for 65 different diseases. If they get out of hand, the neighbors will let you know about it, Hawkins said. House flies can transmit bacteria that causes mastitis in heifers, so if a feed yard is growing heifers for a rancher, the heifers can be exposed to the bacteria long before they have a calf – all as a result of flies. Stable flies are biting flies that are slightly larger than a house fly, but not as big as a horse fly or deer fly. "These are the flies that have a painful bite when you are working cattle," Hawkins said. "They feed during the cooler times of the sum- mer." Their claim to fame – driving animals into the corner of pens while cattle stomp their feet. These flies attack the lower legs and an- imals huddle together hoping the animal next to them gets bit instead of them, he explained. "When that happens, one animal will try to push into the middle of the group, getting deeper into the herd. When animals are crowded like that, their body heat goes up along with their stress level. That's how animals get stressed by stable flies," Hawkins said. Stable flies are costly, reducing gain by up to .46 pound/head/day. PROTERNATIVE-THE NEW MEASURE OF PREVENTION The industry is changing; it's time to take cattle feeding down a new road. Recent advancements in cattle nutrition have opened new routes to help limit pulls, treatment and positively benefit the health of an animal. Adopting a new measure of prevention through the feed is an important first step to help minimize delays on the road ahead. Take a new road with ProTernative ® - a proven probiotic that positively activates the immune system of cattle during times of stress. ProTernative works in the lower gut to influence the animal's natural immunity through an internal active process that only a specific, robust and active live yeast can deliver. The road you've always taken doesn't cut it anymore. Feed ProTernative and take a new measure of prevention.
