I visited a horse owner that had just purchased her own farm this spring. She said she was following the same feeding program that was followed at the boarding barn, but the mare had gained weight. A quick evaluation showed the mare had defiantly crossed the line to a good solid body condition score of a 6.
We knew the forage had not changed as the owner purchased her hay from the boarding barn. When we weighed out the mares daily ration of hay, we came up with 25 pounds per day on average. The mare weighed 990 pounds so she was receiving just over 2.5% of her body weight per day in hay. This was on target with her diet at the boarding barn.
The pasture was still being fenced, so she had a sand ring as turnout. Definitely no added calories there! The mare was also receiving the same amount of work, if not more, since she was now at the owner’s home.
The owner said she had purchased the same feed and still feeding 5 pounds per day, divided into two feedings. She then asked if our formulation had changed. We walked into the feed room and I checked the product. It was the same feed the mare was previously on, and I assured her we had not made any changes.
I then asked how many bags of feed she was using a month. The owner replied “4 … exactly 1 per week.” I quickly did the math: 50 pounds/ 7 days is 7+ pounds per day.
I asked the owner if she had weighed a serving of the feed. She replied “No” because it was the same kind of scoop the boarding barn had used. However, when we weighed her scoop it held 3.5 pounds of feed when filled, not the 2.5 pounds she thought she was providing.
With the extra source of calories identified, we adjusted the mare’s diet and she is on her way back to a healthy body condition!
