SUMMARY
An experiment was conducted to evaluate the effect of dietary inclusion of organic zinc and manganese on growing White Leghorn pullet’s performance. One hundred-day old birds of White leghorn strain were randomly divided into two treatment groups with 5 replicates of 10 birds in each following completely randomized design (CRD). The experimental birds in treatment group T1 were fed basal diet supplemented with in organic salts of Zn and Mn while the birds in treatment T2 were fed basal diet supplemented with 100% organic salts of Zn and Mn. Basal diet was formulated as per BIS (2007) to meet energy and protein requirement. The experiment was conducted for a period of 18weeks till the laying phase started. Body weight and feed intake data were taken fortnightly and feed conversion ratio was calculated. A metabolic trial for duration of five days was conducted at the end of the experiment for evaluation of metabolizability of different nutrients. For this one bird per replicate was selected. For serum mineral profiling especially for Zn and Mn, blood samples were also collected at the end of the trail and further analyzed on Atomic Absorption Spectrophotometer by following the standard protocol.
