Ahles Serving the dairy industry by providing prevention, treatment, and promoting efficiency – since 1958 Bloodwork in Colby Pinkeye We are now offering blood work to be run in Colby for cows and horses. This is especially useful in down cows with suspected milk fever. Be sure to pull a blood sample BEFORE you treat her and we can run it if the cow doesn’t respond. Keep the blood sample refrigerated. We can then check calcium, phosphorus, and magnesium levels to ensure proper treatment. We can also check for signs of severe muscle damage, liver and kidney function, and several other health parameters in cows with difficult to diagnose diseases. Be sure to keep blood tubes on hand so you can bring these into the Colby or Medford office to be run right away. August is the time when we see peak outbreaks of pinkeye. Fly populations are high, and tall weeds in pastures can irritate eyes. The face fly is the main culprit going from animal to animal. Heifers are especially vulnerable because they have low immunity and are not seen regularly. Infection can lead to permanent blindness if not caught in time. Prevention includes fly control with dusts, sprays, or insecticide ear tags, as well as mowing off pastures to reduce tall weeds as eye irritants. Vaccination needs to be done before you see the outbreak. Treatment includes long acting tetracyclines, topical antibiotics, keeping cattle out of bright sunlight, and suturing eyelids in severe cases. Check into our Drug Prices Last year we changed our drug pricing so you can get products in the clinic, from the catalog, or off our trucks all at the same lowest price possible. Our new prices are as low as we have ever had so if you buy from another provider, it may be worthwhile to cross check with our price. West Nile Confirmed in Wisconsin The State Health Department has confirmed over 10 animals this summer infected with West Nile Virus in several different areas across Wisconsin. For animals, this disease is most concerning for horses. Make sure to vaccinate your horses for West Nile as well as Eastern and Western Encephalitis Virus, which have been in our area in previous years. These vaccines do require a booster if the horse has never been vaccinated before. Calf Heat Abatement Young calves experience heat stress starting over 78 degrees. Heat stress can cause decreased feed intakes, weak immune systems, decreased growth rates, and increased water intake. Heat abatement strategies include: 1. Shading 2. Fresh and clean feed and bedding- give fresh starter in evening to prevent spoilage 3. Fresh cool water 2-3x daily- heat stressed calves can drink up to 6 gallons of water daily 4. Breeze- natural or fans 5. Timing stressful events- moving, vaccinating, dehorning- do these early in the morning while it is still cool. 6. Feed calves in early morning and late afternoon – avoids having peak digestion during peak temperatures 7. Be quick to feed electrolytes- early hydration correction can prevent sick calves.
