Broiler Growth Model

Broiler nutritionists are accustomed to using least cost formulation programs to formulate feeds for their broilers, but until the advent of simulation models, such as the Broiler Growth Model produced by EFG Software, they were not able to predict the biological and economic consequences of using those feeds in commercial broiler operations.

Our latest development is another huge step forward in assisting nutritionists to optimise the feeds and feeding programmes for commercial broilers.




Pig Growth Model

EFG Software has recently developed a program that optimises nutritional strategies in pig production. This has been accomplished by integrating their feed formulation program (WinFeed) and Pig Growth Model through an optimisation routine.

Optimum feeding of pigs has long been the aim of production nutritionists in the industry. Even though many pigs are probably fed at close to optimum levels within individual businesses, because the number of variables influencing optimum nutrient levels is very large, the use of formal optimisation tools would be of considerable benefit to the industry. But although such tools have been discussed for a long time in pig feeding circles, few such tools have been developed for practical use.


WinFeed 3.0

winfeed3-homeWinFeed is a Windows-based feed formulation program developed by EFG Software that has been used by nutritionists and students of nutrition since the early 1990’s.

The current version, Winfeed 3.0, is available in two formats, a single-user standalone version, and a network version which enables several users to work independently, but share the same data. This version is ideal for use in a university teaching environment for students of nutrition.


About EFG Software

EFG Software has developed a number of programs that incorporate scientific principles in poultry and pig nutrition into a form useable in the workplace. These programs have been developed to assist nutritionists in the feed industry to make decisions based on the effects of genotypes, feeds, feeding schedules and the environment on the simulated performance of growing broilers and pigs.

The software that we have developed includes a feed formulation program, simulation models that predict the food intake, growth, and carcass composition of broilers, turkeys, and pigs, and optimisation routines that, by integrating these programs, provide users with a facility to develop feeding programs that will, for example, maximise margin over feed cost for different strains of broilers or pigs. There is also some software that we make available free of charge.

Because these programs are best seen as scientific tools, the policy of EFG Software is to share with the users, mostly professional scientists, the theory and ideas on which the programs are based, and to discuss openly the basis and importance of the numbers used for many parameters. We see no value in a model that is simply a ‘black box’. Such is not a scientific tool. This policy of openness also facilitates modification and development of the model to suit the specific needs of our customers. As our programs are based on an open theory, users of our software will gain not only useful information about nutrition but also many valuable insights into pig and poultry science and experimentation.
