Use of Spirulina Platensis in Japanese quail diets in fattening period and responses of performance, meat quality and immunity
Abstract
This study was carried out to determine the effects of different levels of Spirulina Platensis(SP)in Japanese quails (Coturnix coturnix japonica) diet on performance, meat color, meat quality, and immune response. A total of 250 1-d old Japanese quails were randomly distributed to five dietary groups with five replicates.. The powder form of SP was used and experimental diets formulated according to inclusion levels as; The negative control group (NC)(Basal diet- 0% SP-no vaccine)),the control group (C) (Basal diet, 0%SP -vaccinated) the SP1 group (basal diet-2.5%SP,vaccinated), the SP2 group (basal diet- 5% SP, vaccinated) and the SP3 group (basal diet- 7.5% SP, vaccinated). During five weeks experiment, growth performance parameters were determined and at the end of the trial a total of 75 quails (15 quails from each group) were slaughtered and antibody titers (ABT) against the Newcastle (ND) vaccine, meat color values, meat quality parameters were detected and some visceral organs were weighted. Results showed that the inclusion of SP to quail diets at the level of 2.5% increased the final live weight (FLW) and total body weight gain (TBWG) significantly (P<0.05) compared the other groups. The highest feed consumption (FC) was detected in the control group and the best feed conversion ratio was found in SP1 group (P<0.05). Dietary SP did not affect carcass yield, liver, and bursa weights (P>0.05), however, the carcass weight was affected by SP in the diet and the highest value found in the SP1 group (P<0.05). Color values of breast meat changed as depend on level of the dietary SP and a* and b* values increased by the addition of 2.5%, SP to diet. Breast meat pH value, cook loss (CL), and water holding capacity (WHC) affected by the SP supplementation and the highest values were determined in the control group (P<0.05). ABT reading against the ND vaccine was similar between all vaccinated groups independently from the level of dietary SP but significantly low in the NC group (P<0.05). In a conclusion, the use of SP in quail diets at the level of 2.5 % may positively influence performance, carcass weight breast meat quality parameters, color values.
