SAO PAULO, Jan 27 (Reuters) - Brazilian meatpacker JBS

said on Monday it has agreed to buy a stake in

egg sector in a deal that valued Mantiqueira at 1.9 billion

reais ($321 million).

JBS said in a securities filing it had agreed to purchase

shares representing 48.5% of the total capital stock and 50% of

the voting shares of Mantiqueira, meaning it would share control

of the company with its founder Leandro Pinto.
