Effect of Lactococcus lactis JNU 534 Supplementation on the Performance, Blood Parameters and Meat Characteristics of Salmonella enteritidis Inoculated Broilers

Microorganisms, Год журнала: 2025, Номер 13(3), С. 525 - 525

Опубликована: Фев. 27, 2025

Salmonellosis in broilers is a disease with considerable economic implications for the poultry industry. As foodborne illness, it also poses public health risk due to potential cross-contamination. Probiotics have been proposed as alternative feed additives aiming enhance growth, livestock productivity, and overall health. This study investigated dietary impact of Lactococcus lactis JNU 534 on growth performance, blood characteristics, internal organ weight, meat quality inoculated Salmonella enteritidis (SE). A total 96 one-day-old Arbor Acres broiler chickens, comprising both sexes, were challenged SE randomly assigned into two treatment groups housed eight pens (four per each treatment, 12 birds pen). They fed commercial diet 35 days. The consisted control group receiving feed, supplemented 0.3% L. 534. Probiotic supplementation significantly improved average body weight gain, efficiency, carcass yield compared (p < 0.05). Notably, abdominal fat pad was reduced probiotics Meat assessments revealed no significant differences between terms pH, cooking loss, drip water-holding capacity. These findings suggest that promising candidate mitigate negative effects performance farms, without adversely affecting Extending research other types could help confirm its wider use an antibiotics.

Poultry meat and eggs are major sources of foodborne salmonellosis in the United States, with contaminated hatching acting as a key transmission route for Salmonella Enteritidis (SE) from hatchery to farm. Although chemical disinfectants used sanitize eggs, they often fail eliminate internalized pathogens, increasing risk embryo contamination subsequent hatchlings. This study explores probiotics natural, organic-friendly alternative sanitizing reduce SE contamination. A total 560 Lohman Lite inoculated five-isolate mix were sprayed with: Control (phosphate buffered saline), Lactobacillus rhamnosus NRRL-B-442 (LR; ∼8 log CFU/egg), paracasei DUP 13076 (LP; or peracetic acid (PAA; 0.4 %) incubated 18 days. probiotic populations on egg surface, inner shell membrane, internal contents enumerated at regular intervals. LR, LP PAA treatments significantly reduced surface compared control (p < 0.05). By day 18, treated samples negative by enrichment, while ∼2.5 CFU/egg was recovered eggs. effectively contamination, trans-shell migration higher this group LR LP. On counts membrane ∼4 3 groups, respectively, but below detection limits Internal content sampling, including embryos, revealed <20 % positivity probiotic-treated 60-70 groups. These findings demonstrate that application not only reduces also minimizes potential developing embryos. Overall, early may serve an effective, natural intervention In turn, could lower prevalence hatchlings limit its spread grow-out farms.
