A project was planned to study the effect of feeding powdered seeds of Cannabis sativa on the carcass quality of broiler chicks. A total of 160 day-old broiler chicks of equal weight were randomly divided into four equal groups A, B, C and D. Each group was further divided into four replicates with 10 chicks in each replicate. Dried crushed Cannabis sativa seeds were added to the feed of groups B, C and D at the rate of 5, 10 and 20% of offered feed respectively, while group A served as a control. The studied parameters were body weight, feed intake, feed conversion ratio (FCR), dressing percentage, mortality and economics. After an experimental period of 42 days, the data were analyzed statistically. It was revealed from the results that body weight gain was significantly higher (P<0.05), while feed intake was significantly lower (P<0.05), in group D compared to the control. FCR was significantly better in birds of group D compared to controls. Differences in dressing percentage and mortality were non significant between the treated and control groups. Return per chick (in rupees) was significantly higher in group D compared to groups A and B (P<0.05). It was concluded from these results that seeds of Cannabis sativa have remarkable impact on growth of broiler chicks and can help in alleviating feed expenditure incurred on raising broiler chicks.

Key words: Cannabis sativa, Broilers, Weight gain, Feed intake, FCR.
