• Maize germ cake is part of a group of loosely named by-products yielded from the wet milling and dry milling maize industries. It is important to know what process the cake is from because that will affect its feed value.
- Dry milled maize should contain more soluble protein, starch, and phosphorus.
- Wet-milled maize tends to contain more residual oil.
- Organic cake will have high oil levels because oil can only be extracted by pressing, not solvents.
• Maize germ (about 11 % of the grain weight) cake contains 20-24 % crude protein and higher levels of essential amino acids than whole maize as shown in Table 1.
• Other products like maize gluten feed are similar but contain more bran and have different nutritional val-ues. Maize quality and processing methods should be identified well in advance to avoid any nutritional im-balances. Ideally, the feed should be analysed to determine nutritional value.
• The maize germ contains high levels of phytic acid which has some anti-nutritional factors, particularly relating to phosphorus availability, but up to 20 % maize germ cake can be used without reduced productivity in pigs and poultry rations.
• If badly stored, the feed can turn rancid.
• Maize germ cake can replace maize within the ration for layers and during the fattening period for broilers.
• It is essential to develop a sound feeding plan to avoid any nutritional problems

EPrint Type:Practice tool
What problem does the tool address?:The protein supply to organic pigs and poultry requires careful management to ensure an adequate supply of essential amino acids and to avoid overfeeding. Alternative sources of protein need to be used to supply the balance of amino acids needed.
What solution does the tool offer?:By-products of manufacturing processes are useful alternatives. Maize germ cake is a by-product of starch and corn oil production, as well as a brewing by-product.
