By drying it out in the sun, would this prevent mold? My concern is once opened it will grow mold fairly quickly. I dont want to abort calves by having moldy grain but want the benefit of reduced feed cost. I am soliciting all of the microbrewerys in my area. It will be more feed then I can handle or I need to buy more cattle. 100 acres only holds so many. Running 29 head max but if feed is cheap or free could start a calf/feed out type situation. Might be profitable.Lucky_P":1t4ml7pp said:An ensiled product would have a relatively high carbohydrate content that would be fermented, producing organic acids that 'preserve' the product by lowering pH into a range that is not conducive to the growth of spoilage bacteria/fungi.
By virtue of the fact that most of the carbohydrate in brewer's grains has already been removed in the alcohol fermentation process, they no longer qualify as a substrate to be 'turned into silage'.
Drying will certainly preserve feed quality, but studies have also shown that distiller's grains can be stored - even at relatively high moisture levels, for fairly long periods, with minimal degradation of feed value - they'll look like lleh and stink to high heavens, but the cows will still eat them, and the nutrients are largely still there, and mycotoxins have not been shown to be a problem.
Lots of info out there; here's one for starters: http://www.beefmagazine.com/markets/fee ... ers-grains
