abstract
Present study was conducted to understand the affects of nano alumina on different clinical signs and growth parameters in White leghorn chickens. The randomly divided control group was fed with normal standard recommended feed while treated group exposed to nano alumina through oral route in feed for three months. The birds of control group (group I) showed signs of some increased activeness or aggressiveness. At the time of feeding birds from treated group (group II) showed increased response for feeding as compare to group I. There was increased fighting tendency noticed in birds of group II. There was no significant difference in body weight observed between group I and group II throughout the experiment at different time intervals. There was a slight 0.33 %, non significant decrease in the body weight of treated group as compared to controls at 90 days post treatment (DPT).
