A study was carried out to review Bureau of Indian Standards recommendations (BIS) for layer pullet feed and study its efficacy of pre-lay feeds on haematology and serum protein. Commercial layer chicks were fed from 0 to 14 weeks of age as per BIS. At 15 weeks, pullets were randomly assigned to each of five pre-lay diets namely, TI (BIS control), T2-16/2700, T3-18/2700 (%CP/ kcal ME/kg); 14-Same as T2+lysine and methionine by 10% higher than BIS and TS -same as T4 with 2 per cent oil. Signiicantly higher values of Packed Cell Volume, Haemoglobin, Red Blood Cell count and Heterophil/Lymphocyte ratio obtained in the present study from pullets fed with high dense pre lay diet indicated that pullets were healthy with a normal metabolic rate. Significantly higher H/L ratio of the control group indicated that birds seemed to be under stress due to nutritional deficiency during the critical pre-lay periods. also haemoglobin level was lower in this group although it was within normal metabolic range. Total serum protein was high in pullets fed with higher pre-lay protein level of 18 per cent. Hence, it is concluded that pullets nearing lay are under metabolic stress and pre-lay diet containing 2700 kcal/kg of dietary energy and 18 per cent CP is advisable for pullets before sexual maturity as against the BIS recommendation of 2500/16 dietary energy and protein level to lower the stress and to make pullets entering into layer house with sufficient nutrient reserves.
