In Memoriam: Prof. Gordon D. Rosen
On July 22, 2016 the is commemorated the 1st anniversary of the death of Prof. Gordon D. Rosen, He was born on May 9, 1926 and died at Wimbledon 89 years, on July 22, 2015.
The chemical formation became interested and investigated the application of additives in animal feed particularly in the search for alternatives to antibiotics called growth promoters.
To Gordon D. Rosen science owes two exceptional progresses; the application of mathematical research of additives principles and the definition of pronutrients as “Micro ingredient included in the formulation of food in relatively small quantities with the mission of improving physiology, the intrinsic nutritional value and prevent the presence of pathogenic” and poultry owes Gordon D.Rosen to be the first sponsor of World’s poultry Science Journal.
Since 1989 at the age of 63 he suffered a serious nervous disorder that prevented him from continuing to develop its activity and thus the possibility of adapting its definition of pronutrient to the modern poultry and livestock industry was truncated. But now several researchers have classified respecting their initial definition, pronutrients into 10 groups according to the zootechnical application. This has allowed us to develop the use of several molecules that once tested under mathematical criteria have proved a valuable tool in improving the intestine and as an alternative to antibiotic growth promoters. We want to highlight the end that throughout his life Prof. Gordon D. Rosen noted for its scientific value, for his kindness and for his efforts to convey the value of both professionals in the poultry industry.
