Your feed calculator is simply fantastic! I have a 12-year-old pony I bought in summer 2023 with a tendon injury. She was in good condition when we got her, but I was told she easily gets fat and should have 6 kg hay a day. When I increased to 7 kg during light work, her coat got dull, energy dropped, and weight fell fast. No signs of illness, but then I used the calculator in the app. It showed she actually needed about 10 kg of our hay. After increasing, she became happier, looked better, and held perfect weight even through 1.5 months of full turnout. It’s wonderful to know what they’re really getting!
