Tom Roudybush, owner and nutritionist of Roudybush, Inc., began manufacturing pellets, crumbles, and handfeeding formulas in 1985 after doing 16 years of nutritional research at the University of California, Davis. Mr. Roudybush studied various bird species, including 10 years of research on the nutritional requirements of pet birds. There is a commonly held belief among aviculturists that macaws need a higher percent fat diet, especially during the handfeeding period. This is based on some handfeeders having a difficult time maintaining good growth rates and based on observations of what some species of macaws eat in the wild.
No research has been done to determine what the fat or fatty acid requirements for growth are in macaws. Some handfeeders get good growth in macaws using Roudybush formulas and some handfeeders feel that they need to add fat to the formulas. In general, the handfeeders that get good results with Roudybush handfeeding formulas are those that feed a little.. [More]
