Shares of Tyson Foods Inc. rose as first-quarter net income reached $173 million, up about 11 percent from $156 million over last year’s first period, the company said. The Arkansas meat processor said sales reached $8.4 billion, up from $8.3 billion, on growth in its beef and chicken businesses. Tyson also said it expects fiscal 2013 sales to reach about $35 billion, as domestic prices rise from a decrease in protein supplies and increased raw material costs.
