| Abstract |
A total number of 156 hens of tow local strains, Mandarah and Salam of 25 weeks of age were used in this study to investigate the effect of strain and some promoters on the performance of laying hens. Birds of each strain were randomly divided into 4 groups of 39 hens each. The first group fed a basal diet containing 15.88% CP and 2750 Kcallkg diet. The other groups (2; 3 and 4) fed the basal diet supplemented with 120 mg Flavomycinlkg diet; 1.0 g Dinaferm ®/Kg diet and 1.0 g Bionutra ®/kg diet, respectively.
Salam hens were recorded significantly (P< 0.05) higher egg production and egg number than those of Mandarah ones from 29-36 and 25-40 wks for egg production and from 29-36 wks for egg number. Flavomycin treatment had the hiihest (P<0.05 or 0.01) values of egg production and egg number followed by Bio-nutra and Dinaferm ® groups during all the experimental periods. Egg weight and egg mass were significantly (P<0.05) increased in Salam hens vs. those of Mandarah ones, except egg weight through 33-36 wks. Similar egg weights were observed in the different experimental treatments. While egg mass in birds treated with Flavomycin or Bionutra ® was significantly (P<0.05 or 0.01) higher than that of Dinaferm ® during 33-40 wks.
Yolk and shell weights and shell thickness did not show any significant difference due to strain or treatment effects, except for shell thickness in Mandarah birds that had higher (P<0.05) shell thickness than that of Salam ones. Salam birds treated with Bio-nutra® had higher values of shell thickness vs. the control group.
Fertility and hatchability percentages were significantly (P<0.05) higher in Mandarah strain than those of Salam one, while, chicks' weight at hatchini was significantly (P<0.05) lower in Mandarah hens. Hens treated with Bio-nutra had the higest percentaies of fertility and hatchability (P<0.01). Meanwhile, birds fed Flavomycin and Dinaferm were of lower percentages. Chicks weight did not differed significantly due to the dietary treatment.
The two strains had similar values of feed consumption during 33-40 wks, while, feed consumption and feed efficiency were significantly (P<0.05) better for Salam strain than Mandarah one during the other periods of the experiment. Feed consumption of treated groups was significantly (P<0.05) increased than that of the control. Birds treated with Flavomycin or Bio-nutra® had the best values of feed efficiency.
The interaction effects (strain with treatments) were insignificant for previous traits, except for egg weight during 29-32 wks and shell thickness, which were significant (P<0.05).
Salam hens had slightly higher values of digestibility coefficients for the all nutrients than those of Mandarah hens. The supplementation of performance
promoters and the interactions (strain with treatments) affected significantly (P<0.05) the digestion coefficients of DM; CP; CF and NFE, while OM and EE did not significantly differed. Flavomycin and Bio-nutra® showed the highest values of digestion coefficients, meanwhile Dinaferm® had the lowest ones in comparison with those of the control group.
Salam strain exhibited higher economic efficiency than that of Mandarah one (+7.8%). Groups of Flavomycin had the highest economic efficiency followed by that of those fed diet with Bio-nutra (+106.1 and +66.1 %, respectively).
