Abstract
SUMMARY AND CONCLUSION 5. SUMMARY AND CONCLUSIONThe present experiment was carried out at the private farm belonging toDakahlia Governorate, Egypt during June, July, and August 2020. The mainobjective of the present work was to study the Effect of feeding Japanese quailson diets containing some aquatic plants (Azolla and Spirulina).A total number of 600 one day old unsexed Japanese quail chicks wereallotted in ten dietary treatments 60 birds each. Each treatment was performed inthree replicates 20 birds each. Birds were weighted to the nearest 0.1 gram, andrandomly distributed. The experimental designwas,T1 (control), T2 (4%Azolla), T3 (8% Azolla), T4 (12% Azolla), T5 (16% Azolla), T6 (T1 + spirulina 2g/kg diet), T7 (T2 + spirulina 2 g/kg diet), T8 (T3 + spirulina 2 g/kg diet), T9 (T4 +spirulina 2 g/kg diet) and T10 (T5 + spirulina 2 g/kg diet). All experimental groups were reared under similar managerial andhygienic conditions. The performance measurements (body weight, weight gain,feed consumption and feed conversion ratio) were measured. At 7 weeks of agecarcass traits was performed. Also, some blood parameters were measured. Eggproduction rate was determined for three weeks’ period (7- 10 weeksof age). Also egg quality test was measured at 10 weeks of age. Also,economic efficiency for feeding was measured for the growing period.The obtained results could be summarized as follow:- Treatment T5 (16% Azolla) and treatment T10 (16% Azolla + 2.0gSpirulina/kg diet) showed the highest significant values of marketing bodyweight (7 weeks of age). - Treatment T5 (16% Azolla) and treatment T10 (16% Azolla + 2.0gspirulina/kg) diet showed the highest significant values of body weight gainduring the whole period of study (0-7 weeks of age).SUMMARY AND CONCLUSION- Feedadditives (Azolla and Spirulina) generallyreducedfeed intake ofJapanese quails during the experimental period up to 7 weeks of age. - Treatment T5 (16% Azolla), T6 (control + 2.0g spirulina/kg diet) and T10(16% Azolla + 2.0g Spirulina/kg diet) achieved the lowest significantvalues of feed intake of Japanese quails, however, the control treatmentwithout additives recorded the highest value of feed intake during thewhole period of study (0-7 weeks of age).- Feed additives (Azolla and Spirulina) generally improved feedconversion ratio of Japanese quails during the experimental period up to7 weeks of age. - Treatment T5 (16% Azolla) and T10 (16% Azolla + 2.0gspirulina/kg diet) achieved the best significant values of feedconversion ratio of Japanese quails, however, the controltreatment without additives recorded the high value of feedconversion ratio during the whole period of study (0-7 weeks ofage).- Feed additives significantly improved serum blood parametersincluded total protein, albumin, and globulin of Japanese quail birds.- Feed additives did not affect on serum concentration of AST or ALTof Japanese quail birds. - Increasing dietary feed additives resulted in significant decreaseserum concentration of cholesterol of Japanese quail birds. - Feed additives (Azolla and Spirulina) improved the dressing weightand dressing percentage of Japanese quails birds. - The high dressing percent was achieved by treatments T6 (control +2.0g spirulina/kg diet) and T10 (16% Azolla + 2.0g spirulina/kg80 SUMMARY AND CONCLUSIONdiet) - Feed additives improved the percentage of giblets. The highpercentage of giblet was achieved by treatments T5 (16% Azolla),T6 (control +2g spirulina/kg diet) and T10 (16% Azolla+2gspirulina/kg diet). - Treatment T5 (16% Azolla) and T10 (16% Azolla + 2.0g spirulina/kg diet) showed the highest significantly of egg production andegg weight.- Treatment T10 (16% Azolla+2g spirulina/kg diet) showed thehighest value of yolk weight, yolk color, yolk index.- Shell thickness of Japanese quails didn’t affect by dietarytreatments containing Azolla (4-16%) and/or Spirulina.- The best economic efficiency recoded by T5 (16% Azolla), T10(16% Azolla and 2.0g Spirulina), and T4 (12% Azolla)
