Inventory Disclosure [Abstract]  
Inventories INVENTORIES
Processed products, livestock and supplies and other are valued at the lower of cost and net realizable value. Cost includes purchased raw materials, live purchase costs, growout costs (primarily feed, grower pay and catch and haul costs), labor and manufacturing and production overhead, which are related to the purchase and production of inventories.
At December 29, 2018, 66% of the cost of inventories was determined by the first-in, first-out ("FIFO") method as compared to 63% at September 29, 2018. The remaining cost of inventories for both periods is determined by the weighted-average method.
