Background Postbiotics have been established as potential feed additive to be used in monogastric such as poultry and swine to enhance health and growth performance. However, information on the postbiotics as feed additive in ruminants is very limited. The aim of this study was to elucidate the effects of supplementation of postbiotics in newly-weaned lambs on growth performance, digestibility, rumen fermentation characteristics and microbial population, blood metabolite and expression of genes related to growth and volatile fatty acid transport across the rumen epithelium. Results Postbiotic supplementation increased weight gain, feed intake, nutrient intake and nutrient digestibility of the lambs. No effect on ruminal pH and total VFA, whereas butyrate and ruminal ammonia-N concentration were improved. The lambs fed with postbiotics had higher blood total protein, urea nitrogen and glucose. However, no difference was observed in blood triglycerides and cholesterol levels. Postbiotics increased the population of fibre degrading bacteria but decreased total protozoa and methanogens in rumen. Postbiotics increased the mRNA expression of hepatic IGF-1 and ruminal MCT-1. Conclusions The inclusion of postbiotics from L. plantarum RG14 in newly-weaned lambs improved growth performance, nutrient intake and nutrient digestibility reflected from better rumen fermentation and microbial parameters, blood metabolites and upregulation of growth and nutrient intake genes in the post-weaning lambs.

Biotransformation via solid state fermentation (SSF) mediated by microorganisms is a promising approach to produce useful products from agricultural biomass. Lactic acid bacteria (LAB) that are commonly found in fermented foods have been shown to exhibit extracellular proteolytic, β-glucosidase, β-mannosidase, and β-mannanase activities. Therefore, extracellular proteolytic, cellulolytic, and hemicellulolytic enzyme activities of seven Lactobacillus plantarum strains (a prominent species of LAB) isolated from Malaysian foods were compared in this study. The biotransformation of palm kernel cake (PKC) biomass mediated by selected L. plantarum strains was subsequently conducted. The results obtained in this study exhibited the studied L. plantarum strains produced versatile multi extracellular hydrolytic enzyme activities that were active from acidic to alkaline pH conditions. The highest total score of extracellular hydrolytic enzyme activities were recorded by L. plantarum RI11, L. plantarum RG11, and L. plantarum RG14. Therefore, they were selected for the subsequent biotransformation of PKC biomass via SSF. The hydrolytic enzyme activities of treated PKC extract were compared for each sampling interval. The scanning electron microscopy analyses revealed the formation of extracellular matrices around L. plantarum strains attached to the surface of PKC biomass during SSF, inferring that the investigated L. plantarum strains have the capability to grow on PKC biomass and perform synergistic secretions of various extracellular proteolytic, cellulolytic, and hemicellulolytic enzymes that were essential for the effective biodegradation of PKC. The substantial growth of selected L. plamtraum strains on PKC during SSF revealed the promising application of selected L. plantarum strains as a biotransformation agent for cellulosic biomass.

Organic acids (OA) are natural constituents of plant and animal tissues and their uses as feed additives are now being studied worldwide. Organic acids consisted of different acids and mixtures of several acids have an antimicrobial function and promote the growth performance of animals. The current experiment was designed to study the inhibitory activity of the organic acids, palm fat (PF), a combination of organic acids-palm fat (OAPF) against various pathogens and investigate the performance in dietary inclusion of OAPF in broilers. A feeding trial was conducted to determine the growth performance and microbial population in the dietary inclusion of OAPF in broilers. A total number of 96 one-day-old chickens (Cobb 500) were used in this study and divided into two treatment groups with six replicates per treatment. The treatment group was T1 (diet without OAPF) and T1OA (diet with OAPF). The differences among treatment means were tested using an independent t-test. The results showed that T1OA had approximately two-fold inhibitory activity against Escherichia coli E-30 compared to T1. Broilers fed diet supplemented with OAPF had higher (p<0.05) final body weight (BW) and total weight gain (WG) compared to broilers fed T1. Broiler fed with T1OA had lower (p<0.05) feed conversion ratio (FCR) than T1. Inclusion of OAPF in the diet also increased (p<0.05) the lactic acid bacteria (LAB) and reduced (p<0.05) Enterobacteriaceae (ENT) cell population. The inclusion of OAPF in the diet showed significantly improved nutrient digestibility and had a beneficial effect on the growth performances of the broiler chickens with a positive effect on the bacterial population in GIT.
