A brand new medicated feed that combats lethal parasites in wild quail shall be out there to the general public beginning this fall. The brand new drug was developed by researchers at Texas Tech College with the monetary assist of Texas chicken hunters, and it has confirmed efficient in experimental settings on a number of ranches within the Lone Star State.
The U.S. Meals and Drug Administration authorized the aptly-named QuailGuard for public use on Might 23, Texas Monthly reports. This got here after greater than a decade of analysis, testing, and cautious area purposes, which have been funded largely by the Texas quail searching group. Though there are different medicated feeds authorized to be used in farmed quail, that is the primary one to be authorized for wild populations, the FDA factors out in a press release. It’s additionally reportedly the primary publicly-available FDA-approved remedy for wild animals.
The search for a medicine that might assist wild quail started in 2010, which was a horrible 12 months for wild birds in Texas. After seeing mysterious inhabitants crashes within the Rolling Plains area, a historic hotspot for Northern bobwhites, hunters began excited about options. A gaggle of these hunters, lots of them members of the Park Cities Quail Coalition within the Dallas space, raised $7 million to fund a long-term analysis challenge led by Ron Kendall, a scientist and wildlife professor who runs the Wildlife Toxicology Lab at Texas Tech College.
A quail hunter himself, Kendall began by ruling out the most typical causes behind the boom-and-bust cycles which have lengthy outlined Texas quail populations: drought and poor habitat.

“Every part was arrange for a fantastic searching season in 2010,” Kendall instructed the Dallas News in 2019. “The habitat was in excellent form all through the summer season throughout the rolling plains. You needed to be actually cautious driving round ranch roads as a result of there have been so many broods. Then, come fall, you couldn’t hardly discover a quail. I’m not speaking about shedding a couple of. Many ranches misplaced 70 to 90 % of their birds.”
Working with different biologists from Texas Tech and Texas A&M Universities, Kendall’s group trapped and studied hundreds of birds over the next years. The ensuing knowledge pointed to 2 parasites because the main culprits behind the 2010 crash. Researchers discovered that two parasites that had already been acknowledged in wild quail — eyeworms and caecal worms — have been even worse than initially believed. Each worms reproduce quickly within the birds’ eyeballs and intestines and in the end compromise their imaginative and prescient, rob them of vitamins and make them extra vulnerable to predators. And since quail stay in coveys, the parasites can unfold shortly by way of wild populations.
Kendall’s analysis discovered that as much as 98 % of quail populations within the Rolling Plains have been carrying these parasites, which may additionally have an effect on home poultry. This meant there was already an out there remedy within the type of fenbendazole, a de-worming drug that livestock growers have lengthy included into their feed. Kendall suspected it will have the identical optimistic results on wild birds, and his son helped devise a specialised feeder that gave quail cowl from predators.
The outcomes of their preliminary checks on a ranch in Mitchell County have been overwhelmingly optimistic. The FDA noticed follow-up research, which confirmed that the drug was each secure and efficient for wild birds.

“The place we have been utilizing the medicated feed, we weren’t seeing quail crashes and have been seeing sustainable quail populations,” Kendall instructed Texas Month-to-month.
The medicated feed is now being manufactured at a facility close to Fort Price underneath the identify QuailGuard. The corporate producing the feed is co-owned by Kendall and the Park Cities Quail Coalition, which plans to make use of a part of the income to fund conservation and schooling efforts, in accordance with Texas Month-to-month.
