Two questions not related but I will put them together. After milking my new cow for a few weeks now I am noticing clumps of yellow butter looking stuff coming out of one teat. There are not a lot of this and no blood. Just yellow lumps. At first I though it was only as I began milking but now I see one come out after I have been milking a while. Concerned about mastitis, any ideas and do you think the milk from this quarter is ok to drink? Question two, thinking of making my own dairy feed. What ratio and ingredients do you use?
