Document Summary
Factors intake factoring affect feed intake: hen body weight, egg production, higher egg production = higher intake, bigger higher intake, higher higher intake lower = higher intake, egg weight, temperature, max intake = max production. If an egg is laid or not: when you can further lower, has an egg been laid or size change, criticism, can not think of decreasing nutrients too much as egg laying is all or none. If too much is decresed no egg is laid = no profit: can also pahse feed with ca and p. Increase ca over time and lower p: lower p to keep ca:p ratio balanced as too much p can inhibit ca and is bad for the environment and also expensive. Cap: phase feed p, benefits to adding vit d3 in water. Important for consumers: desired color depends on geographical location.
