County Critters with Dr. Hotham Winters in Aroostook County can present many challenges to livestock and horses. Some of these challenges include maintaining body weight and production. Remember that animals require more calories in cold weather, and forage quality here in the County is often high in fiber and low in protein and energy. This means that animals will require supplemental grain to meet their protein and energy requirements. I encourage people to submit forage samples for nutrient analysis, which is important in formulating diets. One should strive to have livestock and horses in good body condition prior to winter. A horse’s ribs should not be visible, but be able to be felt with a modest covering of flesh. Horses deprived of protein and energy may still have big abdomens from overeating poor quality forage, but lose muscle along the back. Cattle should carry fat over the hook and pin bones. Horses with dental problems may require a senior feed or a complete feed. All horses require annual dental care by a veterinarian and older horses should have their teeth floated every 6 months. Good dentition is crucial for proper digestion and maintaining body weight. Another tip for aiding digestion and reducing the risk of colon impactions is ensuring adequate water intake. Warming water to 45 – 60 degrees Fahrenheit can greatly increase water consumption. Also, make certain that mechanical waterers are cleaned daily. Horses and cattle should have access to free choice salt, and cattle should have a balanced vitamin and mineral pack in their grain or in a carrier such as soybean meal, which can be fed daily to ensure adequate intake. In addition, livestock and horses require scheduled deworming and treatment for external parasites, such as lice. Many of you deworm your horses three to four times per year, but probably never have had fecal samples tested for parasites. Fecal samples should be tested in late spring and fall to evaluate effectiveness and ensure proper treatment recommendations. Just because you don’t see worms in the stool, doesn’t mean your animals are parasite free. If you only have a few horses, have your veterinarian check fecal samples from each animal. If you have a herd, check 6 to 10 animals to evaluate the worm burden. You may be surprised at how inadequate your deworming program is. Furthermore, external parasites such as lice can cause weight loss, reduced gains and decreased profitability. In summary, large animals can tolerate cold weather if they have adequate shelter, proper nutrition and general health maintenance. A good relationship with a veterinarian can prove to be a valuable asset. In fact, research has shown a $4 return for each dollar spent on preventative veterinary medicine.
