Profitable dairy farming relies mainly on optimum milk production and a calf a year. Early lactation period  may be called profit period as dairy farmer gets more profit through milk during this period. Lactation is a physiological state associated with dramatic metabolic adaptations and changes in energy balance. During early lactation (first 10 days in milk) the connection between nutrient supply and milk production appears uncoupled as milk yield is increasing at a steep slope while calculated energy balance is simultaneously decreasing towards its nadir. The major criterion for improvement in production is to optimize the efficiency of utilization of the available fodder resource, which can be achieved by adopting basic concepts; like  making the digestive system of the cow efficient, balancing nutrients, achieving high levels of dry matter intake throughout the transition period  through excellent feeding management  and using supplements of protein, starch and lipids to provide nutrients for milk production above those obtained when the efficiency of utilization of the basal feed has been optimized.
