| Summary: | Salmonellosis is a commonly occurring bacterial disease in chickens that leads to increased mortality, as well as a decline in the quality and quantity of hen eggs. This, in turn, causes financial losses in the poultry industry. The objective of this research was to investigate the potential of Lactobacillus plantarum and novel B. salmalaya 139SI as probiotics in to improve performance of laying hens and the quality of eggs. The study at Chuan Chuan Poultry Farm employed a completely randomized design, rearing 30,000 Hisex brown layer day-old chicks in three groups-control (antibiotics only), B. salmalaya 139SI probiotic, and L. plantarum probiotic-over 10 months, with probiotics administered in drinking water at a 0.5% concentration. Variables observed include growth performance of layer, egg weight, the different components of the eggs, such as the eggshells, egg yolks, and egg whites, were also examined to detect the presence of Salmonella spp. Various tests were conducted, including biochemical testing, serotyping, conventional detection using specific agars, and a modern detection method utilizing 16S rRNA sequencing. L. plantarum treatment in drinking water showed significantly different results (P < 0.05) than the others, with a final bodyweight of 2071.98 +/- 41.72 g/chick/10 months and egg weight of 69.52 +/- 2.36 g/egg. The results from all the tests indicated that both probiotics, L. plantarum and B. salmalaya 139SI, can produce eggs free from Salmonella contamination. Moreover, the treatment with L. plantarum demonstrated significant protective effects against Salmonella infection in the eggs, surpassing the protective capacity of B. salmalaya 139SI. |
