Abstract

ABSTRACTThis review discusses current data on nutrition in ostrich breeding birds. Nutritional demands increase during breeding particularly the calcium and phosphorus requirements for egg production. The correct balance of amino acids, vitamins and carbohydrates is important for the maintenance of high fertility after the attainment of sexual maturity at 24 months of age for female birds and 36 months of age for male birds. Most problems relating to health and performance, including fertility, hatching, chick survival, growth rates and deformities in the early weeks, are usually traced to inadequate breeder rations.
