Impact of dietary inclusion of Chenopodium quinoa on growth performance and survival of Hubbard chicken

Abstract

The poultry sector is the most vibrant segment of the agriculture system plays a vital role in the supply of healthy meat products. Broiler production effectiveness is greatly associated with feed formulation. Although, broiler exhibits a relatively fast growth rate, the nutritional profile of its meat has been criticized under conventional human dietary regimes. In the current study, the dietary inclusion of quinoa was assessed to improve broiler growth performance, carcass quality, and health by analyzing different growth, hematological and biochemical, immunological parameters. In the present study, the chicken was fed with 50 g/kg, 100 g/kg, and 200 g/kg quinoa enriched diets in two different experimental groups during the growth phase or finisher phase while chicken fed with diet without quinoa were as control. The 50 g/kg quinoa supplemented chicken group revealed a substantial difference in growth performance in comparison with the control group. In addition, the examination of quinoa dietary supplementation on carcass quality exhibited variable behavior. Further, all the study groups fed with quinoa during the growth phase revealed no remarkable difference in the hematological profile in contrast to the control group except for the chicken group fed (50 g/Kg) during the finisher phase for hemoglobin levels. Likewise, all the quinoa enriched diet given chicken groups showed no significant difference in serum biochemical profile in contrast to the control group except for the 50 g/Kg quinoa fed chicken group during the finisher phase for total globulin levels. In addition, the examination of quinoa dietary supplementation on the broiler serum lipid profile was also assessed and birds exhibited variable behavior as the result of quinoa dietary supplementation. Evaluation of short-term immune response after quinoa supplementation assessed and birds exhibited no marked significance on expression outcomes of interleukin/cytokines (IL 1 beta, IL-6, IL-10) assessed by qRT-PCR analysis. In conclusion, the dietary supplementation of broiler fed with quinoa seeds can enhance the growth performance and the carcass quality of broiler.
