The project was devided into two parts. 1. Research Work 2. Survey Work Research Work In research two hundred broilers chicks were reared in the college. They were brooded uniformly for two weeks. Then 162 birds were selected randomly and divided into three treatments i.e. A, B and C on the basis of depth of littre i.e. 1 inch, 2 inches, and 3 inches respectively. The parameters studied were weight gain, lameness and mortality from 3 weeks to 6 weeks age. Weekly data starting from 3rd week onward revealed that the treatment C having 3 inches depth of littre gained more weight, less leg lameness and differed highly significantly (P<0.01) from B and A. Survey Work In Survey Work three data from types of farms I, II and III (Houses having length less than 50 feet, width less than 30 feet and window height less than one foot from the floor)(Houses having length in between 50-70 feet, width 30 feet and window height 1-2 feet from the floor) and (Houses having length more than 70 feet, width more than 30 feet and window height more than two feet from the floor were collected and analysed. The study was based on three different age groups i.e. 3 weeks, 6 weeks and 7 weeks. The study revealed a highly significant difference (P<0.01) in three age groups. Three weeks age group showed least leg lameness. A highly significant difference was also observed between age groups of 6 weeks and 7 weeks. This difference is because broiler start gaining weight rapidly after 5 weeks. A significant difference was also observed in all the Specification. A highly significant difference was observed between specification I and III and II and III. No Significant difference was observed between specification I and II. It was observed that as the length, width and window height from the floor increased the leg lameness also increased. There was no mortality throughout the experimental period ER -
