Applications of Nutrigenomics in Animal Sectors: A Review

Abstract

Nutrigenomics is the study of gene expression or metabolic pathway depending on different food material. In recent year, nutrigenomics has gained special attention due to its great potentiality for treating chronic disease. In this review, we have emphasized the importance of nutrigenomics on human health and on animal farm, specially on pork and poultry industries. Types of food consumption are crucial factor for human health in term of specific nutrition related gene expression and this knowledge is important for preparation of personalized diet. Human genome project identified several polymorphic gene and few of them are involved in metabolic pathway. The present review demonstrated the metabolism related disease like lactose intolerance and phenylketoneuria which is occurred due to polymorphic nature of that particular gene. Due to high cost of raw material, feed efficiency in pork and poultry industries is a crucial factor. In several investigations, researchers have used different combination of food material to monitor the growth and health of pig and chicken but it needs more accuracy and better understanding. Though the food product development and field application technique has a long way to go, further development in the field of nutrigenomics will definitely show it's potentiality in the food market and the growth of individuals. A greater understanding of these mechanisms will lead us to a sustainable fisheries, more production and other aquaculture activities.

The application of omics technologies for understanding tropical plants-based bioactive compounds in ruminants: a review

“…The term "genomics" refers to the methodology used to map, sequence, and analyze all genes (such as DNA) found in a particular species’ genome. The relationship between an animal feed and genome is known as nutrigenomics [ 26 ]. Understanding the physiological, biochemical, and metabolic processes when examining the responses of organisms to dietary components is required in order to examine the importance of food and diet formulation [ 26 , 27 ].…”

“…The relationship between an animal feed and genome is known as nutrigenomics [ 26 ]. Understanding the physiological, biochemical, and metabolic processes when examining the responses of organisms to dietary components is required in order to examine the importance of food and diet formulation [ 26 , 27 ]. Consequently, studying an organism’s entire transcriptome, or RNA products, is known as transcriptomics.…”

“…It may also be useful for expanding dietary neuroprotective mechanisms and identifying new natural compounds that may be more effective (i.e., activating genes that promote health and reducing the production of disease-promoting genes, which could be incorporated into potential neuroprotective strategies) ( Virmani et al, 2013 ). Several studies have asserted that macronutrients (proteins and carbohydrates), micronutrients (vitamins), and naturally occurring chemicals (flavonoids, coumarins, and carotenoids) play a crucial role in gene regulation ( Banerjee et al, 2015 ).…”

“…On the other hand, epigenomics is the systematic research area of the identification of epigenetic modifications or the regulation of gene expression of individuals. The interplay between nutrient bio-molecules and epigenetic mechanisms are among the main mediators of diet-genome-phenotype interaction in ruminants (Asmelash et al, 2018;Banerjee et al, 2015;Osorio and Moisa, 2019). For instance, it is currently accepted that the nutrition of parents widely affects the epigenetic modifications in progeny and therefore the expression of phenotypic characteristics in livestock (Murdoch et al 2016).…”
