Corn steep liquor

Corn steep liquor is a by-product of corn starch manufacturing industry. It is available to the extent of 0.01 million tone in India.

Nutritive value

It contains 40% CP and 75% TDN. Thus, it is an excellent source of energy, protein and phosphorus.

Inclusion

The  moisture  content  is  about  50%.  Because of high  moisture  content, it  requires special care for its  storage. However,  by  mixing  wheat  bran, rice bran or rice polish at 40% level, it  can be stored and transported easily in gunny bags. Due to its low pH (4-5) it cannot be used more than recommended levels. Due to its high phosphorus content, care should be taken to maintain proper Ca: P ratio by supplementing calcium. It can be incorporated up to 15% and 10% level in the ration of growing calves and lactating cows (Talpada et al., 2002).
