Hi does anyone know what is an approximate daily dry matter consumption of Nigerian Dwarf goats? I'm switching to a different mineral and it says to use 1 oz per 5 pounds of dry matter intake per day, so I need to have an idea of how much my goats are eating each day but it's hard to tell because I used a large wooden frame hayrack that I built and I feed hay free choice out of that all winter and I have 8 does feeding out of it. I've heard anywhere from 3 to 5% of their body weight?? I suppose I could empty the hayrack, then weigh out 100 pounds of hay using a bathroom scale and fill the feeder to see how long it takes to empty and calculate an approximate daily intake that way. But the other variable is that they waste so much hay that I would have to guess at it really.
