A total of one hundred and fifty sexed male broiler chicks (Cobb strain) of day old age were procured for the study. The chicks were randomly divided into ten groups, consisting of fifteen in each group. Groups 1, 2 and 3 were maintained as basal diet control, nephtone control and immuplus control, respectively. Group 4 was maintained on ochratoxin @ 2.5 ppm in feed throughout 6 wks as toxic control without any treatment. Group 5 was maintained on ochratoxin @ 2.5 ppm in feed for the first 4 wks (28 days) of study and thereafter, maintained on basal diet for the next 2 wks (29 -42 days). Group 6 was maintained on ochratoxin @ 2.5 ppm in feed along with nephtone (@ 0.8 ml / 10 birds during first 2 wks; 1.6 ml / 10 birds during third and fourth week; 3.2 ml / 10 birds during the last 2 wks) in water, while group 7 was maintained on ochratoxin @ 2.5 ppennullThesis
