Abstract
The aim of this study was to evaluate the probiotic properties of the selected Lactobacillus strains to improving the growth performance of Japanese quails. The experiments were divided into two parts. In part I, Lactobacillus plantarum SKKL1 and L. curvatus FJNP12 were selected to evaluate preliminary probiotic properties. The results showed that all of selected Lactobacillus strains could survive in the acid tolerance condition and tolerated to 0.3% bile salt. The selected Lactobacillus strains were then tested for an eventual inhibitory action against pathogenic bacteria using agar well diffusion assay. All selected LAB strains produced organic acids to inhibit the growth of the tested pathogenic bacteria. Moreover, all of the selected Lactobacillus strains could inhibit the growth of Sal. Typhimurium and E. coli in co-culture growth experiments. The antibiotic susceptibility test showed that all strains were susceptible to ampicillin, chloramphenicol, erythromycin, gentamycin, penicillin and tetracycline, whereas resistant to kanamycin, norfloxacin, streptomycin and vancomycin. The coexistence test revealed a lack of antagonism against each other of all selected LAB. Thus, these two strains, representing different species, could possibly be combined as a probiotic mixture. In part II, Japanese quails were divided into 5 groups; 1) Basal diet, 2) Bactosac-P (commercial probiotics), 3) L. plantarum SKKL1, 4) L. curvatus FJNP12, and 5) SKKL1+FJNP12. The tested strains were inoculated into basal diet in the form of single and multi-strain preparations. Results found that in all of the treatments supplemented with probiotics Lactobacillus, the numbers of viable cells of probiotics in feed were decreased below log 7 CFU/g feed after 21 d of storage at 4oC. Supplementing probiotics Lactobacillus significantly increased feed intake (FI) than control diet and those supplemented with commercial probiotics. The treatment supplemented with two Lactobacillus significantly decrease H/L ratio than fed with basal diet. The fecal samples of the quails fed Lactobacillus strains contained higher lactic acid bacteria and significantly lower E. coli populations compared with the control diet. The level of cholesterol and uric acid in serum of the quails fed with Lactobacillus strain supplemented diet was significantly lower than fed with the basal diet. In conclusion, two Lactobacillus contained probiotics potential can be used to improve the growth performance of Japanese quails. |
