The changes in the physiological status of dairy animals during the transition period from dry and pregnant to the nonpregnant and lactating stage is the most critical time faced by a dairy cow during her lifetime known as transition period. In compared with other stages of the lactation cycle most health disorders of animals occur during this time. Through continued efforts of long-term genetic selection for high milk yield, cattle have been driven to produce higher quantities of milk in a shorter period of time than evolutionarily required. The crave for high milk yield is associated with a rise in micronutrients, amino acids, and energy requirements. During the period of insufficient levels of these nutrients and metabolites, the animals become more susceptible to an array of metabolic and infectious diseases. These "transition disorders" are responsible for reduced monetary returns to dairy producers. In an attempt to alleviate the risk of these transition disorders, intensive management practices have been employed to improve nutrition and animal welfare during the transition period. The role of micronutrient supplementation plays an important role during the transition period for the enhanced performance of periparturient cow. [ABSTRACT FROM AUTHOR] |
