Quality research: A pre-requisite fit for future feed

M A Kabir Chowdhury, Global Technical Manager – Aquaculture & Sales Director – South Asia, Jefo Nutrition Inc., Canada

Animal feeds have been formulated based on the guidelines for standard nutritional requirement of a species or a group of species. For formulations, over the years, we moved from crude protein/total amino acids to digestible nutrients to metabolizable nutrients in raw materials to formulate diets. A significant progress has been made. However, the quality of studies to determine digestible or metabolizable nutrients in an ingredient for a species or for a group of species has not been standardized. The data generated from these studies sometimes can be questionable.

The reliability of the nutritional requirement guidelines can also be questionable as they are often outdated, often gathered from secondary literatures mainly from studies conducted with very young (juveniles) animals assessing their growth performance. As we know today, nutritional requirement of an animal is rather dynamic, not static as always perceived. The requirement varies from one life-stage to another, and within a life-stage, may vary due to varying environmental conditions, stress situations and other biotic or abiotic factors. For growing animals i.e. for most farm animals, a plethora of solutions has been proposed for improved growth performance or to deal with various environmental or biological challenges.

These solutions are often proposed with very little ‘quality’ research on specific animals. The word ‘quality’ is highlighted here as the term needs to be explained and understood from the points where the ‘quality’ can be compromised. As the industry is moving towards providing precision nutrition for biological, environmental and economic reasons, the need for quality research to generate data pertaining to specific conditions are more important than ever.

We also need to rethink the dogmas blocking us from the reality. One example is the dogma of statistical significance or ‘P-value’ of 0.05. Shall we accept the results if the probability of happening is only 95% instead of 90% or 80%? For example, if a very positive outcome following a process is happening 80% or even 70% of the time, should we not follow that process? In this presentation, I will discuss the steps in a research from initiation to finalization, where errors can happen and how to deal with them including the ways to avoid the “statistical b(l)indness”.
