Evaluation of Weissella Cibaria JW15 Probiotic Derived from Fermented Korean Vegetable Product Supplementation in Diet on Performance Characteristics in Adult Beagle Dog

Abstract

This study was conducted to evaluate the effects of dietary supplementation of <i>Weissella cibaria</i> JW15 (WJW15) isolated from traditional Korean fermented vegetable product (kimchi) as a probiotic feed additive on nutrient digestibility, blood profiles, feces noxious gas emission, and feces <i>Escherichia coli</i> and <i>Lactobacillus</i> counts in adult Beagle dogs. In total, 15 Beagle dogs with an average initial body weight of 10.20 ± 0.38 kg were randomly assigned into three dietary treatments in a 14-day feeding trial. Dietary treatments consisted of basal diet (CON); MJW = CON + 50 g of WJW15 (3.0 × 10⁸ cfu/g); and BJW = CON + 50 g WJW15 (3.0 × 10⁹ cfu/g). At the end of the experiment, the serum concentration of triglycerides and feces ammonia emissions were decreased (<i>P</i> < 0.05) with the increasing level of WJW15 supplementation. High-density lipoprotein cholesterol in serum and feces lactic acid bacteria count was improved (<i>P</i> < 0.05) with increasing levels of WJW15. In conclusion, WJW15 isolated from kimchi supplementation in adult Beagle dog diet may have beneficial effects as a probiotic feed additive.
