Egg Size in Poultry ( A guide to managing egg size)

Managing Egg size in Poultry is a very challenging task. In most of the countries like India, eggs are sold by no's and not by Wt. Morover the problem of Weak Egg Shell and breakage during transportation is more in larger sized eggs. Sometimes pullet sized eggs also create a big problem because customer don't demand this size Egg.
Practically speaking bird's body is like a scooter engine. At optimum performance, the average fuel consumption is low with more mileage and with good health of the engine. Similarly in birds when the protein and energy levels are  perfectly balanced, Egg size, FCR and bird's health are perfect. In new birds sometime pullet sized Egg is so severe that it creates marketing problems. If we increase the Methionine content in the Feed slightly, we get some relief. Similarly in aged birds if we decrease the protein % of the Feed slightly, the egg size is reduced without affecting the % Egg production. The egg shell thickness also improves automatically with the balancing of the Feed.
