A feeding trial was conducted in female parent stock of Swarnadhara for 8 weeks during grower stage. Test diets were formulated at variable levels of energy (2500 / 2400 kcal ME / kg) and protein (16 / 15 % CP) to form 4 treatments (High Energy/High Protein–T1; High Energy/Low Protein T2; Low Energy/High Protein–T3 and Low Energy/Low Protein–T4). 384 grower birds (13 – 20 weeks age) were divided into 32 replicates of 12 birds each to offer four diets randomly to 8 replicate groups under deep litter system. A linear increase in calcium concentration over all from beginning to the end of the experiment in all the dietary groups was observed. But, the pooled mean serum calcium (P ≥ 0.05) values were 14.8, 14.6, 14.7 and 14.8 mg/dl in groups T1, T2, T3 and T4, respectively. However, the pooled mean plasma inorganic phosphorus values ranged non-significantly (P ≥ 0.05) from 5.9 (T2) to 6.3 mg/dl (T3). The varied results indicate a gradual increase in concentration of both the minerals as age advanced. Chosen energy as well as protein levels of Swarnadhra birds during grower stage have showed no adverse effect with respect to blood mineral profile.
