Evaluation of FSP (Fermented Soy Protein) to Replace Soybean Meal in Weaned Pigs: Growth Performance, Blood Urea Nitrogen and Total Protein Concentrations in Serum and Nutrient Digestibility

Abstract

A total of one hundred and forty four weaned pigs with an average BW of 8.09±0.05 kg were used in a 28 day study to investigate the effects of fermented soy protein on growth performance, blood urea nitrogen and total protein concentrations in serum and nutrient digestibility in weaner pigs. Pigs were blocked by initial body weight and randomly allocated to one of four dietary treatments in a randomized complete block design. There were six replications per treatment. Dietary treatments included: SBM (cornsoybean meal basal diet), F 5, 10 and 15 (fermented soy product was used at 5, 10 and 15% to replace soybean meal in basal diet, respectively). ADG (average daily gain) and ADFI (average daily feed intake) were not affected (p>0.05) by dietary treatments during the entire 4-wk study period. There were linear increments in feed efficiency (p<0.01) as the dietary FSP level increased during the entire feeding period. No significant differences were observed for dry matter and nitrogen digestibility during the experimental period (p>0.05). Digestibilities of histidine, lysine and methionine were increased as the FSP level increased (linear effect, p<0.05, p<0.01). Among non-essential amino acids, alanine, glutamic acid, serine, tyrosine and total non essential amino acid digestibilities were increased linearly (p<0.05, p<0.01). There were quadratic effects in protein digestibility (p<0.05). Total amino acid digestibility of the F15 diet was improved compared with the F5 diet (p<0.05). There were no significant differences in fecal consistency score among the treatments (p>0.05). At the end of experiment, BUN (blood urea nitrogen) concentration was increased as the FSP level increased (linear effect, p<0.01) and total protein concentration was lowest (p<0.05) for pigs fed the SBM diet among treatments. In conclusion, the feeding of 10 or 15% FSP to nursery pigs improved feed efficiency, amino acid digestibility and blood urea nitrogen and total protein concentrations in blood.

Effect of partial fish meal replacement by soybean meal on the growth performance and biochemical indices of juvenile Japanese flounder Paralichthys olivaceus

“…Moreover, several studies have shown that the animals fed high-quality protein feed (i.e. FM-based diet versus soy concentrate-based diet and fermented soy protein diet versus SBM diet) had higher blood concentrations of TP and/or lower BUN levels (Takagi et al 2001;Cho et al 2007). These results indicated a relationship between dietary protein quality and protein metabolism.…”

Effects of Different Levels of Fermented Oat on Growth Performance, Nutrientdigestibility, Diarrhea Incidence, Fecal Microorganisms and Emission Gas in Weaned Pigs

“…Although the ingredients was different, Vranjes and Wenk (1995) reported that barley fermented by enzyme had a more impact on chick performance than unfermented barley form. Cho et al (2007) reported that piglets fed fermented soya beans showed increased feed efficiency. The study of Kim et al (2010) also documented that during nursery pigs at 3 to 7 wk of age, a significant increase of ADG and ADFI were observed in treatments fed fermented soybean meal.…”

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).…”
