Abstract
The current study was undertaken for a period of 35 days to assess the impact
of dietary inclusion of dried mushroom (Agaricus bisporus) waste powder (MWP) on
growth performance, serum biochemical profile, antioxidant status, digestibility of
nutrients and carcass characteristics of Japanese quails. A total of one hundred and fifty
day-old quail chicks were distributed among five groups, each containing three
replicates with ten birds allotted randomly to one of the dietary treatments which were
iso-caloric and iso-nitrogenous (NRC,1994). Experimental diets were formulated with
inclusion of MWP at 0, 1.5, 3.0, 4.5 and 6.0 per cent in T1, T2, T3, T4 and T5 groups,
respectively with precise adjustments to other feed ingredients.
Results illustrated significant (p<0.05) improvement in body weight gain in the
groups fed MWP when compared to control. Significantly (p<0.01) better FCR, PI and
PER were observed in T2 and T3 groups when compared to other dietary treatments.
Additionally, increased feed intake (p<0.05) is observed in 6% MWP fed groups.
The serum biochemical profile of the quails demonstrated that inclusion of
MWP up to 6% in the diet had no effect (p>0.05) on serum total protein, globulin, A/G
ratio, glucose, AST, ALT, creatinine and calcium content as compared to the control
group. However, estimated values showed significant increase in serum phosphorus
(p<0.05) and HDL-C (p<0.01) along with significant reduction (p<0.01) in serum
triglycerides, total cholesterol, LDL-C and VLDL-C content in MWP fed groups when
compared to the control group. Serum albumin and BUN levels exhibited a significant
(p<0.05) increase in T5 group when compared to other treatments.
The antioxidant profile of quails depicted significant increase in SOD (p<0.05)
and catalase (p<0.01) activity as well as decrease in MDA content (p<0.01) with the
level of MWP inclusion up to 6% level in the diet.
The digestibility coefficients for OM, EE and NFE remained non significant
(p>0.05) with the inclusion of MWP in the diet. DM digestibility was decreased
significantly (p<0.01) at 4.5 and 6.0 per cent levels of inclusion. However, there was a
significant (p<0.01) increase in CP digestibility in the T2 and T3 groups and CF
digestibility in T2 group. Furthermore, the level of inclusion of MWP up to 6% in the
diet had no effect on per cent calcium and phosphorus retention.
Inclusion of MWP in the diet up to 6% level did not result in any significant
(p>0.05) impact on carcass yield, dressing percentage, ready to cook yield or the per
cent weight of heart, liver, gizzard and giblet when compared to the control group. The
feed cost/kg gain exhibited a significant (p<0.01) decrease in T3 group and increase in
T5 group.
Our current research findings suggest that MWP in the diet can be included up
to 3% level without affecting the performance by improving lipid profile and
antioxidant status of the birds.
