              Abstract 
 Aim:
              Yucca schidigera extract has been successfully used as 
              feed additives in the poultry industry. It enhances the growth and 
              productivity in broiler production. Hence, the present study was 
              designed to analyze the effect of Y. schidigera extract in 
              growth, carcass quality and behavior along with its economical 
              utility in broiler rearing. 
              Materials and Methods: Total, 120 numbers of day-old broiler 
              chicks of equal sex ratio were randomly divided into Yucca 
              supplemented treatment and control group, each having 60 birds in 
              three replications of 20 numbers. The feeding management and 
              rearing conditions were similar for all the groups as per the 
              standard except the Yucca supplementation in the treatment group @ 
              125 mg/kg of feed. The parameters with respect to growth, carcass, 
              behavior, and litter content were recorded as per standard 
              procedures. 
              Results: The Yucca supplementation can effectively enhance 
              growth of 173 g in 6th week by utilizing 
              lesser feed intake than control group, which ultimately proves 
              better feed conversion rate, protein efficiency ratio, and energy 
              efficiency ratio in broiler production. Eviscerated weight of 
              58.50% for the treatment group was significantly higher (p<0.05) 
              than 54.10% in the control group. The breast meat yield of Yucca 
              group (32.23%) was significantly higher (p<0.05) than control 
              (30.33%). More frequency of agonistic behavioral expressions was 
              noticed in the control group than the treatment group. A profit of 
              43.68% was received by usage of Yucca supplementation in the diet 
              on live weight basis. Numerically, lower percentage of moisture 
              was present in Yucca treated group than the control. 
              Conclusion: From this study, it can be 
              concluded that Yucca supplementation has an important role in 
              augmenting broiler‘s growth performance, efficiency to utilize 
              feed, protein and energy, and survivability. Hence, use of Yucca 
              powder in broiler ration could be beneficial to maintain the 
              litter quality, which directly enhances the productivity in 
              broiler production without any adverse effect.

              season, Yucca schidigera.
