One hundred day-old (Hubbard) chicks were reared in the floor pens with wood litter for 2 weeks, after 2 weeks 90 chicks were selected and were randomly divided into 3 groups of 30 chicks each. Each group was further sub divided into three replicates of 10 chicks of groups were placed at densities of either 0.5, 0.75 and 1.0 square foot per bird up to 8 weeks of age. Other conditions were the same for all the groups. Data was recorded in respect of body weight gain, feed efficiency. The average gain in body weight per bird at 8 weeks of age was 1827, 1878 and 1894 gm on 0.50, 0.75 and 1.0 square goot space per bird, respectively. The feed efficiency values were found to be 2.19, 2.21 and 2.21 for the birds kept on 0.50, 0.75 and 1.0 square foot floor space per bird, respectively. Differences in weight gain and feed efficiency were no significant. At the end of the study, 3 birds from each groups were randomly taken, slaughtered, dressing percentage calculated, the meat was analysed for approximate analysis of other extract, protein and ash percentage. However the difference due to the effect of various floor spaces were found no significant except in other extract percentage, which was more in birds kept at 0.50 square foot floor space per bird due to restricted movements. The results of present experiment showed that there was no determental effect due to different floor spaces on the performance of broiler, however, the birds kept at 0.50 showed soiled plumage and about 10 percent showed breast blisters.
