Online published on 20 May, 2023. Abstract The Indian livestock population is growing exponentially and with limited available fodder for livestock, it is becoming difficult to obtain optimum production from the animals. Constraints of fodder availability force to use unconventional feedstuffs. Palatability of certain feedstuff depends on the preand post-ingestive feedback which comprise of smell, taste, texture and flavour of feed and aversion and preference towards particular feed causes due to those factors. Unconventional feeds have low palatability which impacts its intake thus the production. Flavoured additives are substances which are added to those unconventional feeds tuffs to improve its palatability by masking the unpleasant characteristics present in it and thus enhance its intake and production of animal. Preference of animal toward particular feed changes with the taste with sweet and umami taste shows positive preference whereas bitter tastes show negative preference. Flavoured additives increase dry matter intake, average daily gain, and weight gain in growing animals whereas in dairy animals it improves dry matter intake, milk yield, milk fat percentage, feed efficiency and reduces loss of body condition and improves energy balance in early lactating cow. There are few challenges for manufacturing livestock ration and raw material quality and availability is the major cause which impact the cost of production and those challenges can be overcome by the use of flavoured additives to produce economic ration.
