Description Maggots, toads, azolla and water hyacinth are just a few of the unconventional raw materials being considered for poultry feeds in the Philippines. Substituting these for expensive imported materials offers farmers the opportunity to cut their production costs.



Maize is the main imported energy-providing feed. Other potential substitutes which are being looked at by the Philippines Council On Agricultural Research and Development (PCARRD) include cassava, sweet potato, arrowroot, gabi (Colocasia esculenta), pongapong (Amorphopallus), coconut residues and damaged rice.



Damaged rice can completely replace maize in rations but performance is better if it is used to replace only half of the maize. Cassava, too, makes a food replacement for about half the maize in a ration.



To replace imported soybean meal, which is the main protein material used, there is a wider choice. The giant toad (Bufo marinus) can be cooked, dried and ground to produce a meal with 54% crude protein, and this is comparable to fish meal. The maggot of the common housefly can be grown on poultry manure to produce a meal with 60% crude protein but, if processed with the residue of the poultry manure, the true protein value drops to 27%.



Earthworm meal has a crude protein content of 60% and gives better results than soybean meal and fishmeal. Rations containing roots and leaves of water hyacinth at levels of about 15%. increased the weight-gain of broiler birds.



Dried and ground azolla meal has the potential to produce a meal with about 20% crude protein, although at inclusion levels of more than 20, it becomes unpalatable. If azolla meal is fed at levels up to about 7% more and bigger eggs are produced. Fresh azolla mixed with snails and rough rice makes a good ration for ducks.



Leaves from some trees like Anaboing (Trema orientalis) and Sesbania grandiflora can be used to replace other protein materials, up to about 20% of the ration.



PCARRD is hoping that the Government will encourage poultry farmers to try some of these alternative feeds as a means of reducing the huge import bill.
