Effects of Dietary Fermented Flammulina velutipes Mycelium on Performance and Egg Quality in Laying Hens

Effects of the Agaricus bisporus stem residue on performance, nutrients digestibility and antioxidant activity of laying hens and its effects on egg storage

Objective

The purpose of this experiment was to investigate the effects of the Agaricus bisporus stem residue (ABSR) on the performance, nutrients digestibility, antioxidant activity of laying hens, and its effects on egg storage to determine the appropriate dosage of ABSR, so as to provide a scientific basis for the effective utilization of ABSR.

Methods

A total of 384 53-wk-old Nongda III layers were randomly divided into six treatments, four replicates in each treatment and 16 birds in each replicate. The control treatment was fed with basic diet, while experimental treatments were fed with diets of 2%, 4%, 6%, 8%, and 10% ABSR respectively. The experimental period was 56 d.

Results

The results showed that compared with the control treatment, ABSR had no significant effect on laying performance (p>0.05). The crude protein and total energy digestibility of experimental treatments was significantly higher than those of control treatment (p< 0.05). When eggs were stored for 1 wk, 2 wk, and 3 wk at 25°C, there were no significant differences in egg storage between the experimental treatments and the control treatment (p>0.05). The superoxide dismutase (SOD) activity and glutathione peroxidase (GSH-Px) activity in the serum of the experimental treatments were significantly higher than those of the control treatment (p<0.05), and the malonaldehyde (MDA) content did not change dramatically. SOD activity in yolk of experimental treatments was significantly higher than that in control treatment (p<0.05); MDA content in yolk was markedly lower than that in control treatment (p<0.05). The activity of GSH-Px and SOD in yolk of experimental treatments was significantly higher than that of control treatment stored at 25°C for 21 d, and the content of MDA was significantly lower than that of control treatment (p<0.05).

Conclusion

ABSR can be used to improve the antioxidant activity of laying hens without affecting laying performance.

Use of Medicinal Mushrooms in Layer Ration

Simple Summary

The extensive use of antibiotics in the poultry industry to increase production performance has led to human health hazards. The use of natural herbs as antibiotic substitutes has been reported in the poultry feed industry. Therefore, the objective of this review was to determine the effect of different levels of mushrooms and their extract in diet on laying performance and health status. On the basis of previous findings, dietary supplementation using mushrooms as a natural feed supplement sustained laying performance and improved immunity in laying hens.

Abstract

Application of different medicinal mushrooms intended to enhance production performance and health status has created an importance demand in poultry production. One goal of using medicinal mushrooms is to get rid of antibiotics in poultry feed without affecting the optimum performance. Increasing concerns about this issue have led to more attention on antibiotic substitutes and a significant demand for them for organic egg production. Thus, supplementation with medicinal mushrooms is a new concept for research in layer production, however, there is still a great deal of confusion about inclusion levels and the mode of action of medicinal mushrooms on production performance and health status in laying hens. Taking this into account, this review outlines the experimental uses of medicinal fungi on the growth performance, laying performance, egg quality, and health status of layer birds based on previous findings to date. Finally, we highlight that supplementation with medicinal fungi can play a role on the immunity, health, and production performance in laying hens.

Dietary Inclusion of Mushroom (Flammulina velutipes) Stem Waste on Growth Performance, Antibody Response, Immune Status, and Serum Cholesterol in Broiler Chickens

Simple Summary

The continued overuse of antibiotics in the poultry industry with the purpose of increasing production performance and health status has led to human health hazards. This research explores the use of medicinal mushrooms to get rid of antibiotics in poultry feed without affecting optimum performance. Most medicinal mushrooms contain biologically active substances such as polysaccharides, glycoproteins, and other macromolecules, which can serve as good dietary supplements and immuno-modulating agent in chickens. Therefore, the objective of this study was to examine the effect of Flammulina velutipes mushroom stem waste (MW) on Growth performance, antibody response, immune status, and serum cholesterol in broiler chickens.

Abstract

This study was carried out to investigate the effects of mushroom (Flammulina velutipes) stem waste (MW) on growth performance, antibody response, immune status, and serum cholesterol in broiler chickens. A total of 252 1 day old Arbor Acres (AA) male broiler chicks were randomly assigned into four treatments with seven replications of nine chicks each. The duration of experimental period was total 42 days. Dietary treatments includes a standard basal diet as negative control (NC) group; control diet with antibiotics (Chlortetracycline) considered as positive control (PC) group; 1% mushroom stem waste (MW) fed group; and 2% MW fed group. No significant differences (p > 0.05) was observed on average daily feed intake, body weight gain, and feed conversion ratio among experimental groups. Antibody titers against Newcastle disease (ND) and infectious bursal disease (IBD) were higher (p < 0.05) in 2% MW fed group than NC and PC fed groups. Serum immunoglobulin G (IgG) was higher (p < 0.05) in both levels of MW fed groups than in the NC and PC. Serum interleukin-2 (IL-2), interleukin-4 (IL-4), interleukin-6 (IL-6), were higher (p < 0.05) in 2% MW fed groups than in the NC and PC fed groups. Total cholesterol concentration was lower (p < 0.05) in both levels MW fed groups than in the NC. High density lipoprotein cholesterol (HDL) was lower (p < 0.05) in both levels of MW fed groups than that of NC and PC fed groups. MW at 2% level can be used as potential phytogenic feed supplement in broilers.

Dietary inclusion of mushroom (Flammulina velutipes) stem waste on growth performance and immune responses in growing layer hens

BACKGROUND

Medicinal mushrooms contain biologically active substances that can be used as an immune-modulating agent in poultry. The present study aimed to investigate the effects of Flammulina velutipes mushroom waste (FVW) on performance, immune response and serum immunity in growing layer hens.

RESULTS

No significant differences (P > 0.05) were observed with respect to average daily feed intake, body weight gain and feed conversion ratio among the experimental groups during the entire study period (1-70 days). Antibody titers against Newcastle disease and infectious bronchitis were higher (P < 0.05) in the FVW fed groups than in the control and antibiotic groups. On day 28, serum immunoglobulin (Ig)A and IgG were higher (P < 0.05) in the 6% FVW group than in the control and antibiotic fed groups. On day 70, serum IgA was higher (P < 0.05) in FVW fed groups than in the control group; IgG was higher (P < 0.05) in the FVW groups than in the control and antibiotic groups. However, IgM was higher (P < 0.05) in both the 4% and 6% FVW groups than in the control and antibiotic groups for both experimental periods. Serum cytokine interleukin (IL)-2 and tumor necrosis factor-α concentrations were significantly higher (P < 0.05) in both the 4% and 6% FVW grousp than in the control and antibiotic groups; IL-4 was significantly higher (P < 0.05) in the FVW groups than in the control group; and IL-6 was significantly higher (P < 0.05) in the 6% FVW group than in the control and antibiotic groups.

CONCLUSION

FVW at the 6% level can be used as a potential phytogenic feed stuff in growing layer hen rations with respect to improving the immune response without affecting normal weight gain. © 2018 Society of Chemical Industry.
