I had no idea that people use blood meal in cattle food. I think that's gross! Now sorry if any of you use it but I just don't think that cattle are meant to eat blood. I know it's probably dried and made into a powder or something I don't really know but I would think that cattle are meant to eat plants..... they're herbivores..... plant eaters. What do you all think of this? I know it's an organic fertilizer and all but .... well.... yuck! To think that is possibly passed into the milk from your cow into the glass you drink..... ugh.
