Cottonseed

Whole cottonseed has high protein (23%), high energy in the form of fat (20%), and crude fiber (24%) on a dry matter basis. Compared with other commonly available protein supplements, whole cottonseed is the only one with both additional high energy and high fiber. This combination is especially attractive when feeding the high producing, early lactation dairy cow in negative energy balance – a cow in need of both energy and fiber. Also, the energy (fat) content of WCS makes it a valuable addition for cows under heat stress who may have a reduced appetite
The energy in WCS is primarily from fat, which if fed at a reasonable level, won't interfere with forage digestion the way the starch in corn can. Research has also shown that the fat in WCS improves reproductive performance.
