Role of micronutrients in production and reproduction of farm animals under climate change scenario.

Abstract

Climate change poses significant challenges to livestock production worldwide. Wherein, it affects communities in developing nations primarily dependent on agriculture and animal husbandry. Its direct and indirect deleterious effects on agriculture and animal husbandry includes aberrant changes in weather patterns resulting in disturbed homeorhetic mechanism of livestock vis a vis indirectly affecting nutrient composition of feed and fodder. The nutritional stress (i.e. non-availability of nutrients in the required quantity and quality for particular livestock) is the critical factor affecting livestock performance, productivity, and reproductive efficiency. Nutritional stress may arise from both macro- and micro- nutrient imbalances; however, micronutrients are of paramount importance in climate change context due to their role in various vital functions of body namely, body metabolism, production, reproduction, and health. The micronutrients, minerals and vitamins, when supplied in adequate quantity and proportion aid in mitigating the stress induced by climate change on animals. Here, we tried to discuss the impact of climate change induced stresses on milk production, reproduction, and metabolic acclimation of heat-stressed animals. Furthermore, emphasis is given on the importance of dietary micronutrients management strategies to support livestock health and resilience during changing climatic conditions. By addressing the nutritional needs of livestock, farmers can achieve sustainability and well-being in livestock production under changing climatic condition.
