Effects of different levels of metabolite combination produced byLactobacillus plantarumon growth performance, diarrhoea, gut environment and digestibility of postweaning piglets

Abstract

A study was conducted to investigate the effects of different levels of metabolite combinations produced by Lactobacillus plantarum on growth performance, diarrhoea incidence, gut environment and nutrient digestibility in postweaning piglets. A total of 40 piglets were assigned into one of five treatments: (1) negative control (free antibiotic); (2) positive control (0.03% antibiotic of chlortetracycline); (3) Met 1 (0.1% metabolite combination of TL1, RG14 and RS5 strains); (4) Met 3 (0.3% metabolite combination of TL1, RG14 and RS5 strains); and (5) Met 5 (0.5% metabolite combination of TL1, RG14 and RS5 strains). After 5 weeks of the trial, the average daily gain (ADG) and daily feed intake (DFI) was significantly (P B0.05) improved in Met 5 group compared to the negative control and Met 1 group. The diarrhoea incidence was significantly (PB0.05) reduced when were piglets fed with positive control and Met 5 dietary treatment. The pH value and Enterobacteriaceae (ENT) in the gut were reduced in Met 5 treatment as compared to negative control and Met 1 group. However, lactic acid bacteria (LAB) counts and short chain fatty acids (SCFA) in the gut were significantly higher (PB0.05) when piglets were fed with Met 5 dietary treatment. In contrast, feeding of metabolite combination to piglets did not improve energy utilisation. In addition, piglets fed with Met 5 dietary treatment improved protein digestibility compared to the negative control and Met 1 group. The results obtained in this study showed that feeding of 0.5% metabolite combinations could improve growth performance, gut health environment and protein digestibility in postweaning piglets.

Dietary Postbiotic Lactobacillus plantarum Improves Serum and Ruminal Antioxidant Activity and Upregulates Hepatic Antioxidant Enzymes and Ruminal Barrier Function in Post-Weaning Lambs

“…The potential of postbiotics is ascribed to the existence of organic acids and antimicrobial compounds like bacteriocins, which possess inhibitory ability against important pathogenic bacteria including Escherichia coli, Listeria monocytogenes, Pediococcus acidilactici, Salmonella typhimurium and Vancomycin-resistant Enterococci (VRE) [1,2]. The dietary supplementation of postbiotics of monogastric like broilers [3][4][5], layer hens [6] and piglets [7,8] were shown to have better performance and were comparable or performed better in comparison to antibiotics. In broilers exposed to heat stress, postbiotics inclusion was shown to alleviate the heat stress effects by the greater growth performance, immune status and gut health [9].…”

The effects of supplementation of yeast (<i>Saccharomyces cerevisiae</i>) and postbiotic from <i>Lactobacillus acidophilus</i> on the health and growth performance of young Jersey heifer calves

“…Both SC and postbiotic from Lactobacillus spp. have been found to lower the frequency of diarrhoea in production animals when fed separately (SC: Galvao et al, 2005;Magalhaes et al, 2008;Hill et al, 2009;Thu et al, 2011;Loh et al, 2013;Alugongo et al, 2017b) (postbiotic: Thu et al, 2011Loh et al, 2013)). Hill et al (2009) found that the supplementation of 4 g of SC per day to calves in the milk for 42 first days of life lowered the faecal score, which also indicates a lower frequency of diarrhoea.…”

Effects of lactulose supplementation on growth performance, nutrient digestibility, blood profiles, faecal microbial shedding, faecal score and faecal noxious gas emission in weanling pigs

“…We suggest that the environment we provided may have had no negative effect on the pigs and less of a response on the blood parameters to dietary lactulose. Post-weaning diarrhoea is one of the critical problems faced by the hog industry, and lactulose is a potential diarrhoea inhibitor (Kleesen et al 2001;Loh et al 2013). Lactulose acts as an effective prebiotics in (non-typhoid) Salmonella carriers (Schumann 2002).…”
