Abstract
The study was conducted to evaluate the effects of dietary bacteriophage (BP) supplementation on production performance, excreta microflora, and moisture content as well as blood profiles in broilers and layers. A total of 80 broilers (DOC) and 80 layers(36 weeks old) were randomly allotted in 4 treatment groups (20 birds in each group) in a completely random block designfor 4 weeks and 6 weeksfeeding trials, respectively. Dietary treatments for broilers included: i) CON (basal diet), ii) ANT (CON+0.5 g antibiotics/kg feed), iii) BP1 (CON+0.25 g bacteriophage/kg feed) and iv) BP2 (CON+0.5g bacteriophage/kg feed). Dietary treatments for layers included: i) CON (basal diet), ii) BP1 (CON+0.2 g bacteriophage/kg feed), iii) BP2 (CON+0.35g bacteriophage/kg feed), and iv) BP3 (CON+0.5 g bacteriophage/kg feed). In broilers, the inclusion of antibiotic and bacteriophages did not affect feed intake (P=0.78) among the four groups but BWG in BP2 group significantly differ during 1-2 weeks (P=0.046) and 3-4 weeks (P=0.016) of ages compared with the CON group. FCR of broilers was found significantly higher compared with CON (P=0.011), ANT (P=0.022) and BP1 groups (P=0.013). In case of laying hens, BP2 (P=0.001) and BP3 (P=0.0004) groups had significantly higher egg production than those of CON group during 36-39 weeks. In addition, egg production in BP1 (P=0.02), BP2 (P<0.0001), and BP3 (P=0.0003) groups increased significantly at 40-42 weeks compared with CON group. However, in case of egg weight, no significant difference was observed among the four treatment groups (P=0.86). In case of excreta microflora, inclusion of antibiotic and bacteriophages significantly reduced the E. coli (P<0.0001) and Salmonella (P<0.0001) concentrations in excreta of the broilers and layers compared with the CON group. However, on excreta moisture content of layers and blood profiles (RBC, PCV, HB, WBC and lymphocyte) of broilers, no significant effects of dietary antibiotic and bacteriophages supplementation was observed throughout the whole experiment (P>0.05). In conclusion, bacteriophage supplementation has beneficial effects on production performance of broilers and layers and can reduce excreta microflora concentration in commercial broiler and layer chicken.
