Effect of fermented soya beans on diarrhoea and feed efficiency in weaned piglets

Abstract

Aims: To evaluate anti-diarrhoeal and growth enhancing properties of fermented soya beans in weaned piglets. Methods and Results: In a first phase piglet diet, toasted full-fat soya beans (20%) were replaced with either cooked soya beans or Rhizopus microsporus or Bacillus subtilis fermented soya beans. The effect on the incidence, severity and duration of diarrhoea in enterotoxigenic Escherichia coli (ETEC)-challenged weaned piglets was determined (pen trial, 24 piglets per treatment). Severity of diarrhoea was significantly less on the diet with Rhizopus-fermented soya beans compared with the control diet containing toasted soya beans. Piglets fed fermented soya beans showed increased feed intake (13 and 12%), average daily weight gain (18 and 21%) and feed efficiency (3 and 8%) (for Rhizopus and Bacillus-fermented soya beans, respectively). However, in the treatment groups an unequal mortality and a potential unequal distribution of receptor-positive piglets were observed. Conclusions: Cooked and fermented soya beans could be beneficial in the control of diarrhoea in ETECchallenged weaned piglets (particularly Rhizopus fermented) and significantly improved weight gain and feed intake (particularly Bacillus fermented). Significance and Impact of the Study: Fermented soya beans could offer benefits with respect to the control of diarrhoea and feed efficiency in piglets.

Effects of dietary protein supply, weaning age and experimental enterotoxigenic Escherichia coli infection on newly weaned pigs: health

“…There was a rapid initial increase in ETEC shedding in the faeces of challenged pigs immediately post infection followed by a gradual decrease. Others have reported the same pattern over a similar time period (Nabuurs et al, 1993;Kiers et al, 2003).…”

“…The oral challenge of pigs with pathogenic E. coli has been widely used as a model of PWC (Sarmiento et al, 1988;Nollet et al, 1999;Madec et al, 2000;Van Dijk et al, 2002;Kiers et al, 2003;Montagne et al, 2004). The experimental model used here produced prolonged faecal ETEC excretion in all challenged pigs post infection.…”

Study on effects of microbial fermented soyabean meal on production performances of sows and suckling piglets and its acting mechanism

“…To remove the antinutritional factors and improve biological values of soyabean meal (SBM), many species of microbes such as lactic acid bacteria (Cho et al, 2007) and Bacillus subtilis (Kiers et al, 2003) have been used for fermenting SBM. This result indicated that SBM fermented with the optimal microbial proportions could reduce antigen protein by enzymatic hydrolysis and microbial fermentation as well as increase protein, lactic acid, probiotics, acid-soluble protein, total and most amino acid contents in fermented soyabean meal (FSBM), which is in agreement with previous reports (Hachmeister and Fung, 1993;Zhao et al, 2008).…”

“…There are some reports about FSBM application in piglets (Kiers et al, 2003;Feng et al, 2007;Lee et al, 2007;Song et al, 2010); however, few reports can be found for its application in sow's reproduction.…”

“…Fermented soyabean meal (FSBM) is manufactured through fermentation of SBM with beneficial microbes such as yeast, lactic acid bacteria, and Bacillus subtilis (Kiers et al, 2003). Microbial fermentation can effectively eliminate ABSTRACT.…”
