Abstract

A total number of 32 Freisian cows in El-Shohada farm (Mnofia governorate, Egypt) were divided into 2 groups. The first was fed a ration equals 115% that of the maintainance requirements while the second was fed 160% that of the maintainance during the dry period. After parturition each group was further subdivi ded into two subgroups in such a way that one subgroup was fed on low energy ration while the second on high energy ration for 10 weeks. Studies were carried on to test the effect of these programs on the animal productivity. The cows kept under high plane of nutrition showed an increase in both milk yield
and calves body weight.
