Abstract

This study was conducted to investigate the effects of energy density in DRY PERIOD on subsequent milk production. Milk production and milk components of 2143 milking cows were used and NEl of the FAR-OFF and CLOSE-UP period’ s diets were 1. 35, 1. 45, 1. 55, and 1. 44, 1. 54, 1. 65 Mcal/kg of dry matter. Descriptive statistics of herds were described. The results were showed as least square and standard error of means in early lactation (120 day) and whole lactation period. As energy density increased in the FAR-OFF and CLOSE-UP periods, there was no difference in milk yield in early lactation period, but there was a linearly increase in whole lactation period (P < 0. 05). Milk composition until 120 d didn’ t changed with increasing energy density in the FAR-OFF diets, but milk fat percentage was linearly decreased (P < 0. 05) in whole period by increasing dietary energy in FAR-OFF and until 120 d and whole lactation period (P < 0. 05) by the CLOSE-UP diets. There was a linearly increase in somatic cell count in early and whole period with increment energy density in the FAR-OFF and CLOSE-UP diets. Generally, increasing energy density in DRY PERIOD improved milk production and increased somatic cell count, and less milk fat content over lactation period might be independent of the DRY PERIOD diet and it’ s a function of length of lactation and milk amount.
