Dietary Inclusion of Blood Plasma with Yeast (Saccharomyces cerevisiae) Supplementation Enhanced the Growth Performance, Nutrient Digestibility, Lactobacillus Count, and Reduced Gas Emissions in Weaning Pigs

Abstract

This experiment was performed to examine the hypothesis that blood plasma (BP) with yeast (Saccharomyces cerevisiae) supplement in the diet of weaning pigs could provoke the growth performance, nutrient digestibility, fecal microbial, and reduce harmful gas excretion. A total of one hundred and eighty healthy piglets were taken and assigned (complete random blocks) to three dietary treatments as: Phase 1: Treatment (TRT) 1-6% BP; TRT 2-3% BP + 3% yeast; TRT 3-6% yeast. Phase 2: TRT 1-3%; BP., TRT 2-1.5% BP + 1.5% yeast; TRT 3- 3% yeast. Phase 3: TRT 1- Control (CON) (Basal diet); TRT 2- CON; TRT 3- CON for six- weeks. Each treatment had twelve replicates and five (three gilts and two barrows) pigs per pen. Dietary inclusion of BP with yeast supplementation significantly increased the body weight of piglets during phase 2 (p = 0.003) and phase 3 (p = 0.032). In addition, TRT2 group piglets had a significant improvement in average daily gain at the end of each phase and overall (p = 0.047, 0.025, 0.018 and 0.012, respectively). At phase 3, TRT2 group piglets showed a significant improvement on nutrient digestibility of dry matter (p = 0.012) and nitrogen (p = 0.040). The fecal microbiota of TRT2 group piglets showed a tendency to increase the number of Lactobacillus counts at phase 1 (p = 0.07) and phase 2 (p = 0.06) as well as, a significant improvement at phase 3 (p = 0.021). In addition, TRT2 group piglets had trend to decrease NH3 (p = 0.074) and H2S (p = 0.069) during phase 2, and significantly reduced NH3 (p = 0.038) and H2S (p = 0.046) at phase 3. However, the fecal score of piglets remains unaffected during the entire trial. At the end of phase 1 piglets’ IgG (p = 0.008) was significantly increased with the inclusion of BP with yeast supplementation. Based on the positive effects on body weight, average daily gain, nutrient digestibility, Lactobacillus count, and reduced gas emission, we suggest that dietary supplement with BP and yeast in the diet of weaned piglet could serve as an excellent alternative to antibiotics growth promoters.

“…Additionally, increasing daily CGCM intake increased the ADG of pigs. The results observed in this study are in accordance with previous studies showing that SCP can be used as alternative protein supplements to replace plant or animal protein supplements improving growth performance in broilers ( Schøyen et al, 2007 ; Chand and Khan, 2014 ) and pigs ( Hu et al, 2014 ; Sampath et al, 2021 ). Furthermore, blood plasma has high protein and energy digestibility in diets ( Chae et al, 1999 ; Jeong et al, 2016 ); however, replacing blood plasma by increasing CGCM supplementation did not affect nutrient digestibility of diets, indicating that supplementing 2.1% CGCM can replace 1.5% blood plasma without compromising the nutrient digestibility in diets fed to nursery pigs.…”

“…Furthermore, the dietary inclusion of HY decreased BUN in early-weaning pigs. This is consistent with the finding of Zhang et al [21] in relation to the improvements in CP digestibility and N-retention; however, contrasting results were presented by Sampath et al [19], who noted differences in yeast strain, minimal dose, diet composition, and pig age. Therefore, the supplementation of HY in the nursery diet could be utilized more efficiently in order to optimize the nutrient balance.…”

“…This is confirmed by our previous report that showed lower microbial shedding of E. coli and Salmonella spp. in weaning pigs fed HY [19,38]. This supports the criteria of acetate and propionate concentrations as the main energy sources for the growth of beneficial bacteria, and lower diarrheal incidence in this investigation.…”

“…The linear improvement of the apparent total tract digestibility of CP, nitrogen (N) excretion, and N retention in the HY-supplemented diet was possible due to the highly digestible protein source. It is easily digested in young piglets and thus can be provided as a superior protein source in the nursery diet [19,20]. An increase in CP digestibility would indicate the increased digestibility of amino acids that are further used in the porcine intestinal cells.…”

Evaluation of Dietary Probiotic (Lactobacillus plantarum BG0001) Supplementation on the Growth Performance, Nutrient Digestibility, Blood Profile, Fecal Gas Emission, and Fecal Microbiota in Weaning Pigs

“…Escherichia coli ( E. coli ) and Lactobacillus were enumerated by plating 10-fold serial dilution (in 1% peptone solution) onto MacConkey agar plates (Difco Laboratories, Detroit, MI, USA) and lactobacilli medium III agar plates (Medium 638; DSMZ, Braunschweig, Germany). To isolate the E. coli and Lactobacillus , it was anaerobically incubated at 39 °C for 48 h and 37 °C for 24 h before counting, respectively [ 31 ]. All bacteria were counted and log 10 transformed before statistical analysis.…”
