Ostrich Farming Techniques: Key Points for the Feeding and Management of Breeding Ostriches
(1) Feed: Artificially raised breeding ostriches should be given a balanced daily ration according to the nutritional requirements of breeding ostriches. Feed is usually formulated according to the breeding ostrich's requirements for calcium and phosphorus (female ostriches have very high calcium and phosphorus requirements during the laying period). Breeding ostriches are most prone to deficiencies in fat-soluble vitamins and trace elements such as iodine, iron and zinc. However, feed high in fat should not be given in excess, because ostriches have no gallbladder and therefore a poor ability to absorb fat. In particular, the energy supply must not be too much, to prevent breeding ostriches from becoming obese and gaining weight, which leads to a drop in the laying rate or even a stop in laying.
