Advances in poultry nutrition

Nutritional advances as discussed in these proceedings embrace historical perspective as well as futuristic perspectives. Indeed, we must have a clear understanding of the past to identify key "advances" that will mold the future of poultry nutrition. Early nutrition research is discussed with reference to in ovo nutrition and nutritional needs up to day seven post-hatch. In addition, the nutrition of the hen is key in early nutrition of chicks. Key advances that have impacted diet formulation are energy and nutrient liberating enzymes, and the use of L-threonine. Key nutritional mechanisms that have been elucidated the past two decades include nutrition in immunity and gut health. Advances in nutritional specifications for specific genetic strains of broilers and the use of models to tie nutrition into production objectives are clear advances that will only flourish in the future.

The Relationship

Seventy years have elapsed since the Nutrition Society was founded and John Boyd Orr became its first Chairman. Over the intervening period, nutrition research has embraced and responded to a wide variety of challenges as the requirements of research have evolved and changed. This paper reflects on some of the major challenges that have influenced nutrition research over the past 70 years and considers where nutrition stands today along with the challenges for the future. In the past, these challenges have included food security and improvements in animal nutrition to enhance production through problems of overnutrition, such as CVD and obesity, as well as the recognition of the importance of early-life nutrition. The challenges for the future include how to translate the increasingly comprehensive and complex understanding of the relationship between nutrition and health, being gained as a result of the genomic revolution, into simple and accessible policy advice. It also includes how we learn more about the ways in which diet can help in the prevention of obesity as well as the ways in which we prevent the rise in complex diseases in emerging nations as they undergo nutritional transition. From this, it is clear that nutrition research has moved a long way from its initial focus on nutritional deficiencies to a subject, which is at the heart of public health consideration. This evolution of nutrition research means that today diet and health are high on the political agenda and that nutrition remains a priority area for research. It has been 70 years since 1941 when the Nutrition Society was established, under its first Chairman, John Boyd Orr. At that time there were many who believed that nutrition research had reached its peak and there was little left to discover. This view stemmed from the fact that most vitamins and minerals had been discovered and that the syndromes associated with nutritional deficiencies in these were largely known. Despite this gloomy prognosis, the intervening 70 years have witnessed a remarkable evolution in nutrition research, which has underpinned key Government policies, ranging from food security right through to public health. This review considers some major developments that have helped to shape nutrition research over the past 70 years and in so doing have changed its frontiers.

Past Half

It is Probable that no country outside the borders of the United States has, during the past half century, been more widely and more inaccurately presented by our American writers, than the Republic of Mexico. An examination of this surfeit of material and the multiplicity of its authors’ approaches to their topic discovers our Catholic neighborland to have long proved both an irresistible lure and an enigma to the professional producers of run-of-the-mill travel volumes as well as to the more popular (i.e., lighter-weight) theorists on economics and sociology. Their enthusiastic, even florid rhetoric has been ceaselessly inspired by the color and drama of Mexico; but otherwise their persistent output rarely gives much evidence of a clear understanding of Mexican attitudes or ideals and so, of competence to fathom the true significance of this nation’s turbulent history. Since the past cannot be overlooked in any safe estimate of the future, this is a regrettable fact that could prove most detrimental to that much-desired inter-American accord which has already cost the American taxpayer some millions of dollars. There are two easily understood reasons for such lack of insight on the part of so many of our writers; this has already served to rouse the resentment and disrespect of the Mexican reader of the American press while also resulting in a sincere acceptance by Anglo-Americans of a decidedly strange mixture of misinformation and absurdly ill advised opinion for “the truth about Mexico.”
