The sudden fall has been attributed as a reaction to higher corn prices and weak chicken prices, analysts said.

Kenneth Zaslow, a food analyst at BMO Capital Markets, predicted that Pilgrim's Pride would post a fiscal year loss of $3.53 per share, higher than his previous forecast for a loss of $2.72, reports Reuters India.

According to Reuters India Zaslow said in a note to clients that the chicken industry had not done enough to cut production at a time when feed costs were increasing.

Pilgrim's Pride shares fell to $18.99 early on Monday, their lowest in two months. In late afternoon trading they were down 9.94 percent at $19.49.
