The serum biochemical profile of Japanese Quails which were supplanted with zinc in the diet was studied. The concentration of serum glucose, total protein, uric acid, AST, chloride and phosphorus changes when the birds were fed with zinc supplemented diet while the concentration of cholesterol, ALT, alkaline phosphatase and magnesium remains unchanged. The levels of serum glucose, AST and phosphorus increases with the increase of zinc in the diet while the level of uric acid and chloride decreased. Total protein level increased initially on zinc supplementation but further increase in the amount of zinc resulted in decrease level of total protein.

The response of Japanese quail to supplementation of Morinda citrifolia truit juice with reference to growth, production and immune response was studied. The Japanese quail were fedMorinda citrifolia ITuitjuice @5% from 0-7 weeks during growing period and from 8-14 weeks during laying periods. The body weight gains, feed conversion ratio, performance index and immunity status were recorded in both control and treated groups. The result revealed better growth performance in theMorinda fed groups compared to the control group. Overall performance index of Morinda group was also better than control group. The humonil immune response ofthe Morinda group was significantly better than control group. The Morinda fed birds produced 30.90 eggs / hen housed during 8-14 weeks of age. While only 20.9 eggs/hen housed produced by control groups. The overall analysis of the growth and production performance of both the groups revealed that supplementation of M. citrifolia crude truit juice @ 5% daily enhanced the body weight gain and egg production performance in the Japanese quail.
