Effect of Multiple Probiotics on Performance and Fecal Ammonia Nitrogen in White Semi Broiler
Year: 2024
Type: article
Abstract: This study was conducted to evaluate the multiple probiotics prepared based on lactic acid bacteria, Bacillus subtilis, and photosynthetic bacteria for the efficient production of Baeksemi (white semi broiler) for Samgyetang. The experimental groups were LacBacil group (1.0 × 107 CFU/g Bacillus subtills and 1.0 × 107 CFU/g Lactobacillus acidophilus), LacBalcilPho group (1.0 × 107 CFU/mL Bacillus subtills, 1.0 × 107 CFU/mL Lactobacillus acidophilus and 1.0 × 107 Cell/mL Rhodopseudomonas sp.), and a control group (non-addition). The LacBalcilPho group had the highest body weight and total weight gain at the end of experiment, followed by the LacBal group which was higher than the control group, significantly (P<0.05). Feed intake and feed conversion rate of the multiple probiotic groups showed no significant difference compared to the control group. NH4-N concentration was lower in all groups of multiple probiotics than in control group after 3 weeks of testing (P<0.05). At the end of the test, the levels of NH4-N were lower in the following order: LacBalcil group, LacBalcilPho group, and control group (P<0.05). Salmonella sp. population of manure showed the lowest level in LacBalcilPho group at 3 weeks of testing (P<0.05). At the end of the test, Salmonella sp. showed a lower population in the following order: LacBalcilPho group, LacBalcil group, and control group (P<0.05). Therefore, based on the above results, it is expected that multiple probiotics using lactic acid bacteria, Bacillus subtilis, and photosynthetic bacteria will function as a probiotic for improving growth and intestinal environment in Baeksemi.
