* Tyson Foods Inc. said depressed chicken prices cut its fiscal first-quarter profit 53%--to $27 million, or 12 cents a share--and probably will mean lower-than-expected earnings for its second quarter. Revenue declined 2% to $1.74 billion. Separately, Tyson said it cleared a regulatory hurdle after a Justice Department review of its planned acquisition of IBP Inc. expired without additional action. Tyson wants to buy the beef and pork producer to expand beyond poultry.
