Dietary Complex Probiotic Supplementation Changed the Composition of Intestinal Short-Chain Fatty Acids and Improved the Average Daily Gain of Growing Pigs

Abstract

At present, probiotics are being extensively evaluated for their efficacy as an alternative to antibiotics, and their safety in livestock production. In this study, 128 (Duroc, Yorkshire and Landrace) pigs with an average initial body weight of 28.38 ± 0.25 kg were allocated to four dietary treatments in a randomized complete-block design. There were eight pens per treatment, with four pigs per pen (two barrows and two gilts). Dietary treatments included: (1) control diet; (2) control diet + 0.05% complex probiotic; (3) control diet + 0.1% complex probiotic; (4) control diet + 0.2% complex probiotic. During the 28-day experimental period, the feeding of 0.1% complex probiotic in the diet increased body weight and average daily gain (p < 0.05). The addition of complex probiotics decreased total cholesterol and glucose concentrations in the blood (p < 0.01). Acetate concentrations in the blood increased from 0.1% complex probiotic in the diet (p < 0.05), while NH3 and H2S emissions in the feces decreased (p < 0.05) from 0.1% or 0.2% complex probiotic in the diet. In conclusion, dietary complex probiotic supplementation changed the composition of intestinal short-chain fatty acids and improved growth performance for growing pigs.

Characterization of the Effects of a Novel Probiotic on Salmonella Colonization of a Piglet-Derived Intestinal Microbiota Using Improved Bioreactor

“…Energy and dry matter are also parameters that may vary depending on the study. Here, again, results differ between already-published studies [ 65 , 66 ]. The results from our study suggest that little to no increase in digestibility was achieved from the probiotic action.…”

Protective effects of Bacillus licheniformis on growth performance, gut barrier functions, immunity and serum metabolome in lipopolysaccharide-challenged weaned piglets

“…Wang et al. ( 68 ) observed that B. licheniformis significantly increased the content of acetic acid and butyric acid contents in the feces of growing pigs. VFAs regulate macrophage production of inflammatory mediators.…”

Strategies for reducing noxious gas emissions in pig production: a comprehensive review on the role of feed additives

“…compared with the antibiotics fed group. However, some other studies found that supplement of probiotics (Lactobacillus plantarum, Saccharomyces cerevisiae, Bacillus subtilis, Enterococcus Faecium, Lactobacillus acidophilus) could reduce the ammonia contents in pig manure [32][33][34][35]. Wang et al [35] found decreased fecal ammonia and hydrogen sulfide emissions in 0.1% or 0.2% probiotic supplemented growing pig diet.…”

Wang et al [35] found decreased fecal ammonia and hydrogen sulfide emissions in 0.1% or 0.2% probiotic supplemented growing pig diet. Kim et al [25] showed that hydrogen sulfide and ammonia emissions were decreased in Bacillus licheniformis and B. subtilis supplemented diet in growing pigs.…”
