Chaff

 

the resulting waste products from threshing and cleaning the grains of cereal and leguminous plants. It consists of hulls, bits of spikelets, ground leaves, underweight grains, and the seeds of weeds. The nutritional value of chaff is higher than that of straw. One kg of wheat chaff contains 0.43 feed units and 26 g of digestible protein; 1 kg of rye chaff contains 0.40 feed units and 21 g of digestible protein; and 1 kg of oat chaff contains 0.44 feed units and 23 g of digestible protein.

Chaff may be used in mixtures with succulent feeds, wet mash, molasses, and other slops for fattening cattle, horses, and swine. When grain is harvested by combine, the chaff is mixed with straw and is thus used as feed for animals.
