Application of Nutrigenomics for Enhancement of Body Growth in Ruminants

the same diet may perform differently and it is due to differences in ability of nutrients to interact within the biological systems affecting molecular pathways resulting in differences in body weight gain, production or reproduction performances. For better understanding of the above processes, nutrigenomics and endocrinomics; two emerging fields that are of great help to discover the differential expression and function of genes occur with different diets, have come up. Nutrigenomics is dealt with the effects of each and every bioactive chemical in foods and supplements that alter gene expression in an animal. On the other hand, nutrients alter the hormonal inter milieu of the animal thereby ‘turn on’ or ‘turn off’ of a particular set of pathways affecting ‘switching on’ or switching off’ of a defined set of genes (Endocrinomics). Hence, there is always a crosstalk between nutrigenomics and endocrino-genomics. This paper highlights the importance of nutrigenomics and endocrinomics, and their interactions during the process of growth in domestic animals in general and bovine species in particular.
