Effect of low‐nutrient‐density diet with probiotic mixture (Bacillus subtilis ms1, B. licheniformis SF5‐1, and Saccharomyces cerevisiae) supplementation on performance of weaner pigs

Abstract

A total of one hundred and forty, 28 day‐old weaner pigs [Duroc × (Yorkshire × Landrace)] with an initial body weight (BW) of 6.56 ± 1.25 kg were used in a six‐week treatment (7 replicate pens per treatment; barrows, and 2 gilts/pen) to evaluate the effect of low‐nutrient‐density diet supplement with probiotic mixture supplementation on the growth performance, nutrient digestibility, faecal microbial and gas emission of weaner pigs. Pigs fed low‐density diet with probiotic mixture supplementation had linearly increased (p = 0.028, 0.014) the body weight (BW) at weeks 3, and 6. Moreover, average daily gain (ADG) was linearly improved (p = 0.018, 0.014, 0.014) at weeks 3, 6 and the overall experiment. However, there were no interactive effects found on the nutrient digestibility of dry matter (DM), nitrogen (N) and energy (E) throughout the experiment. Dietary inclusion of a low‐density diet with probiotic mixture supplementation has improved the faecal lactobacillus counts linearly, but E. coli was unaffected during the trial. On day 42, Ammonium gas emission was significantly decreased in pigs fed a low‐density diet with probiotic mixture supplementation. However, H2S, acetic acid and CO2 were not significantly affected by the probiotic mixture supplementation diet. Low‐density diet with probiotic mixture supplementation had positively affected the growth performance, faecal microbial and faecal gas emission on weaner pigs.

Effects of the Probiotic, Lactobacillus delbrueckii subsp. bulgaricus, as a Substitute for Antibiotics on the Gastrointestinal Tract Microbiota and Metabolomics Profile of Female Growing-Finishing Pigs

“…Furthermore, LDB induced a significant increase in Lactobacillus abundance and a significant decrease in the abundance of Treponema_2 and Prevotellaceae_NK3B31_group in the top ten most abundant genera. Similar to the results obtained by Sampath et al [57] and Pupa et al [14], Lactobacillus abundance was increased in pigs fed an LDB-supplement diet in our study. Probiotic supplementation inhibits Treponema_2 in pig caecal digesta [12].…”

Nourishing neonatal piglets with synthetic milk and Lactobacillus sp. at birth highly modifies the gut microbial communities at the post-weaning stage

“…In addition, Novotni-Dankó et al (2015) and De Greeff et al (2016) stated that the administration of SM increased body weight and reduced pre-weaning mortality in piglets, respectively. Concurrently, a nutritional approach to the use of probiotics has gained more attention since the 1970's (Fuller, 1977), and this finding was corroborated by many researchers (Nguyen et al, 2019;Sampath et al, 2022) who suggested that a probiotic live microorganism used as a therapeutic adjuvant could improve the feeding behavior and reduce the morbidity and mortality of animals. Such probiotics were recently used in different strains with different efficacies; some of them were established to provide certain benefits to the host (Patil et al, 2015).…”

Dietary Bacillus spp. supplementation to both sow and progenies improved post-weaning growth rate, gut function, and reduce the pro-inflammatory cytokine production in weaners challenged with Escherichia coli K88

“…Although daily gain showed improvements in pigs fed a 0.05% probiotics supplement, the BW, daily feed intake and gain/feed were unaffected over 6 weeks was constant with Mun et al [ 45 ] who found same result in weaning pigs fed diet supplemented with 0.01% Bacillus subtilis and Bacillus licheniformis probiotics. While, Sampath et al [ 46 ] study reveals that dietary Bacillus licheniformis and Bacillus subtilis has significantly improved the growth performance of weaning pigs. The discrepancies result from the above-mentioned studies made us to hypothesized that age of pigs, species, and strain is also a considerable fact to relate the efficacy of probiotics as they are very active in animals during microbiome development and/or when microbiome stability is compromised.…”
