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. [ABSTRACT FROM AUTHOR]

Current study was designed to investigate and compare the effects of a locally isolated strain of Lactobacillus brevis MF179529 (LB) with commercial probiotic (CP), and yeast (Y) on growth performance and meat quality of chicken. One-day old Cobb broiler chicken (n=270) were randomly allocated into six groups (A-F) having 45 birds in each group. Groups, A-E were continuously given 1g of different probiotics (LB, CP, Y, LB+CP, LB+CP+Y, respectively) in 10 L of drinking water for 42 days except group F (Negative Control) which was given plain drinking water. Feed consumption and weight gain were recorded on weekly basis. Subsequently, at day 42, birds were slaughtered and breast meat samples were processed for meat quality parameters. FCR of groups A, D and E was significantly lower than group F. Similarly, group A displayed high body weight compared to B, C and F groups (p<0.05). Among color attributes, L* (groups A-E) and b* (Group A, C-E) were significantly higher than group F, while a* of group A was higher (p<0.05) than groups C and F. The results indicate that supplementation of LB alone and in combination with, commercial probiotics lead to significant improvement (p<0.05) in growth rate, total proteins, mineral and fat contents as well as color attributes and tenderness of meat.
