Cottonseed oilcake futures prices declined by Rs 13 to Rs 1,146 per quintal today on increased selling by traders.
Market analysts said speculators preferred to off-load part of their positions on expectations of higher crop this season, following timely monsoon rains.
They said shifting of interest in other crop among cattlefeed makers further dampened the market sentiment.
