Evaluation of Yucca schidigera extract as feed additive on performance of broiler chicks in winter season

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.

“…The chemical analyses of the complete diets were similar to the intended formulation (Tables 2 and 3); however, the chemical analysis for Cu concentration was slightly higher than expected for diets formulated to contain 75 and 150, ppm of added Cu from Cu-AA (AAFCO, 2014 11 ). Analytical variation for Cu is listed at 25% (AAFCO,…”

“…8,9 Lactobacillus plantarum is a facultative heterofermentative plant-associated lactic acid bacterium that is tolerant against bile salts and low pH, improving survivability in the GIT (de Vries et al, 2006; da Silva Sabo et al, 2014). 10,11 These findings certainly make it a promising bacterial source that could potentially be used in swine diets. However, in the context of these studies, all research has been carried out under highly controlled environments.…”
