Table egg farms are monly pany owned with a smaller fraction on contract. 2. Egg farms monly receive new pullets at ages from 16 to 20 weeks. 3.

Plants owned by integrated poultry panies, broiler industry. ? Independent panies that process poultry from other suppliers., ., fowl processors. Components of the poultry industry ?

The use of advanced mechanical engineering has greatly reduced the occurrence of human egg handling to the point that eggs are rarely touched by human hands. As the eggs reach the end of each level, automatic collectors place the eggs into plastic egg handlers (“D”). Plastic egg handlers carry the eggs directly to the egg processing facility via a large overhead belt. D D D These eggs are traveling to the egg processing/breaker facility. Eggs are mechanically washed with a mild detergent and sanitized (“E”). Eggs are washed in 120oF water. E E Here the eggs are entering the first stage in the egg grading process. The eggs are evaluated by an automated puterized detection system. Eggs are graded into categories of AA, A, B, and Loss Quality Standards. Brushes transport eggs away from the egg graders to the packaging area of the plant. It is at this point that eggs will either be placed into cartons or be sent to the breakers. This is a view of the entire “carton line.” Each stack of cartons (blue, white, yellow, pink) represent
