An experiment with 720 pullets was conducted to investigate the effect of dietary energy levels of pullet and dietary energy and fat of laying ration on subsequent performance parameters during 14-20 and 22-44 weeks of age. In the first period, white leghorn pullets were fed with two diets of low and high density energy (2600 and 3200 Kcal ME/kg). In the lating period (second period), birds, in...
thirty multiparous holstein dairy cows with average body weights of 687±15 kg and body condition scores of 3.25±0.15 were allocated to 1 out of each 3 groups, immediately after parturition (dim=11) and in a completely randomized design. the first group was fed diet low in rumen undegradable protein (rup; 5.1% of dry matter), the second group fed with medium rup (7.2% of dry matter) while the th...
