Abstract
In this study we tested the effect of altering ostrich feed, by adding silage to feed in the ratio 2:1,
by reducing feed levels to 90% and 75%, by adding antimicrobial growth promoter Zinc bacitricin and
flavoumycin and presenting probiotics as liquid and powder. For each trial a control was set up with only
normal prescribed feed supplied. All the birds used were health kept under high hygiene and vaccinated and
dewormed to remove interference from pathogens. The results indicated that silage improved palatability
and food intake. Reducing feed levels did not significantly alter the FCR or the performance of the birds.
Growth promoters increased FCR but mortality was high. Probiotics were more effective when presented in
liquid form than powder. The results show that data on effectiveness of feed supplements should be
extrapolated to ostriches with caution.
