I had looked for the "bestcob" corn cob horse bedding and TSC stopped carrying it. Cal-Ranch had never heard of the concept. Maybe it's a weather-related shortage, probably aggravated by all the other shortages we had this past year.The Aflatoxin in corn is made worse by poor growing conditions, like drought which is very bad this year. It is in the corn in the field, before it is even milled into feed. .... Problem is you can not smell it usually. Some bedding made from corn cobs will have it, too.
