Importance of Proteins in Laying Hens

Protein is one of the six essential nutrients needed in a laying hen̵7;s diet. The other five are water, carbohydrates, fats, vitamins, and minerals. The percentage of protein needed in the diet changes with age.

  1. Significance

    • Proteins are made up of more than 23 amino acids, and chickens require certain levels of each amino acid.

    Function

    • Proteins are essential for proper growth of the hen and for egg production. If the diet has too few proteins, the hen may have stunted growth and may not be able to lay eggs.

    Sources

    • Protein is usually obtained in the diet from animal sources--meat meal, fish meal, or milk waste--as this form is more effective than proteins from grains. Soybeans also provide valuable proteins.

    Starter Ration

    • Chickens are fed differently during each growth period. Chicks will need a high-protein food (18 to 20 percent) until they are about six weeks of age. This is called a starter ration.

    Grower Ration

    • After six weeks of age, chicks will be fed a grower ration. For chicks destined to be laying hens, this protein level will be about 14 percent of the diet.

    Laying Hen Ration

    • At five months of age, the hens will then be fed a laying hen diet of about 16 percent protein. This higher protein level will help her develop good eggs.
