Official launch of the Australian feed ingredient database
FEED represents the primary cost of broiler production, therefore the formulation of cost- effective diets that meet broiler nutritional re- quirements is critical.

gressively backfill older data (and add missing de- scriptive data where pos- sible) to build on the ro- bustness of this database, so that this resource may continue to compile and deliver relevant informa- tion to nutritionists and researchers.
To ensure this objective is met, nutrient specifica- tions of feed ingredients must be accurately deter- mined.
This database, support- ed by AgriFutures Chick- en Meat, compiled data from a total of 12 compa- nies or databases, includ- ing Adisseo, Ajinomoto, Cootamundra Oil Seeds, DuPont, Evonik, Poultry Hub, Novus, Premier Nu- trition and RCI.

the prediction of the true mean of the population is poor for many ingredient nutrient specifications.
By compiling and as- sessing the variation with- in current Australian and global feed ingredient nu- trient specifications, it is clear that there are areas which are lacking recent Australian data, particu- larly sample numbers and standard deviations.
Consequently, near in- frared calibrations are of- ten used within integrated operations to estimate the nutrient composition of feedstuffs.
The authors would also like to acknowledge the following open access sources which were also included – Feed Grain Partnership, Feedipedia and INRAE-CIRAD- AFZ Feed Tables.
However, the data we presently have may be quickly enhanced by en- suring all data provided presents the number of samples or standard devi- ation, as this is critical to assess the extent of varia- tion within our feed ingre- dients and subsequently the level of uncertainty within diet formulations.
Thus, not only does this project deliver a use- ful resource for Austral- ian poultry nutritionists, industry and researchers, it is clear where focus should be placed moving forward.
However, these readings often end up being re- ceived as ‘historical’ data, as it can be some time before they reach the nu- tritionist due to practical constraints, and consult- ant nutritionists may not have access to NIR and must rely on book values.
Further data was also sourced from published journal articles where re- quired.
Thus, there are three key recommendations arising from this project:

Thus, Australian broil- er nutritionists have ex- pressed concern, as many nutrient specification da- tabases contain dated in- formation or lack Austral- ian specific data.
The mean value, sample numbers, and standard de- viations are also reported.
Therefore, to address this concern, recent Aus- tralian and global feed ingredient data for com- monly used Australian feed ingredients has been compiled to assist Aus- tralian broiler integrator nutritionists achieve more precise diet formulation and realise improvements in production efficiency, reduced safety margins and feed costs.
One of the main obser- vations from this project is that the standard devia- tion or variability of the Australian data was quite high, particularly in rela- tion to the global data.
• Perhaps more impor- tantly, strong focus needs to be placed on improving our sampling methodol- ogy and reporting prac- tices within industry and research to ensure an ac- curate representation of the nutrient content and variability within Austral- ian feed ingredients

Data is reported for 42 ingredients with 102 nu- trient specifications per ingredient.
• To increase the amount of recent Austral- ian nutrient data where possible – in particular areas of high variation, lacking mean values or standard deviations in- cluding non-starch poly- saccharide measurement, minerals (particularly digestible calcium), di- gestible amino acids and starch (within some ce- reals including triticale, sorghum, corn, oats)
However, in order to be useful to industry in the long term, it is essential that the database is updated and continues to expand on a regular, ongoing basis, so that it may continue to pro- vide relevant information and highlight areas which require further research or change.
Importantly, the stand- ard deviation and sample number provided mean that the quality and ac- curacy of the data can also be determined.

While we have some excellent data, it is clear that our vast continent brings with it challenges in consistency, as the wide variation of environments, climates, growing meth- ods, cultivars and such that exist are likely all at-
