Document Summary
Avs 101 - lecture 21 - poultry and egg production. U. s. produces 187 million eggs per day. Farm lock less than 5,000 birds. Goal is to produce with as little production cost as possible. Not to produce as many eggs as possible. Six to twelve birds per cage eight is optimal. Without pecking order will keep pecking each other. Mortality rate equal to or lower than floor system. Can get crushed into wall by other birds when scared and die on floor system. Raised specially for egg production, not meat. When sold, meat typically used in pet feeds lower quality. Birds produce for one year and then sold. If new lock is too costly that year wait one more year. Chickens go through forced molting (rest period) Cut down on light eight hours. Increase light and food and water again. Pecking order will peck and pinch. Bigger the air cell, less fresh the egg.
