“…In the present study, the fermentation quality of the SPV and CF silages showed lower lactic acid concentration but higher pH value and acetic acid concentration than those reported in previous studies using silages ensiled with more short‐length materials (Van Man & Wiktorsson ; Mangwe et al . ). Although chopping length might affect such high pH values for both the experimental silages, especially for the CF silage, more short‐cutting (approximately 3 cm length by a cutting machine) CF silages prepared in another experiment showed similar higher pH values after 3 months ensiling (H.L.…”

This study aimed to investigate the effects of replacing alfalfa hay (AH) with a mixture of cassava foliage silage and sweet potato vine silage (CSP) (1:1 on a dry matter (DM) basis) on ruminal and intestinal nutrient digestion in sheep. Four wethers were fed a control diet containing 35% of AH and two treatment diets containing 15% and 30% of the CSP as substitute for AH at 1.5 times the metabolizable energy required for maintenance. Replacing AH with the CSP silage did not affect DM intake, whereas it linearly increased (P < 0.05) the intake of ether extract and acid detergent insoluble nitrogen (ADIN). Increasing the CSP substitution linearly decreased (P < 0.05) ruminal DM and neutral detergent fiber (aNDFom) digestibility; however, it did not affect total tract aNDFom digestibility. The CSP substitution did not affect nitrogen (N) intake and duodenal total N flow, whereas it linearly increased duodenal ADIN flow (P < 0.01) and decreased ruminal ammonia-N concentration (P < 0.01), and intestinal (P = 0.08) and total N digestibility (P < 0.01). These results indicate that replacing AH with the CSP reduced the ruminal N degradation as well as the digestion of ruminal aNDFom and intestinal N.

“…The previous study reported that applied Lactobacillus formosensis in SPV silage reduced DM loss and increased in vitro rumen N digestibility [ 23 ]. Also, application of LAB as silage inoculants potentially increased the digestibility in rumen [ 24 ].…”

“…Aerobic stability is an important parameter in determining SPV silage quality considering its high WSC content. After ensiled, original SPV silage still contains a lot of WSC, approximately 13.9% of DM [ 23 ]. Silage treated with LB resulted in the highest aerobic stability, particularly LB silage was 4 times greater (149.2 vs 36.4 h) than LP silage in the present study.…”

ObjectiveThis study was conducted to evaluate the effect of homo or hetero fermentative inoculants on fermentation quality and aerobic stability of sweet potato vine (SPV) silage containing Italian ryegrass hay as moisture absorbent.MethodsThe SPV was harvested at 15% dry matter, mixed with Italian ryegrass hay at 1:1 ratio on a fresh weight basis, and chopped to 3 to 5 cm length. After then, the chopped forage mixture was ensiled into 20-L mini silos in quadruplicate for 7, 48, and 100 days after application of microbial inoculants at 1.2×105 colony forming units (cfu)/g of forage following: no inoculant (CON), Lactobacillus plantarum as a homo fermentative (LP), Lactobacillus buchneri as a hetero fermentative (LB), and mixture of LP and LB at 1:1 ratio as a combo fermentative (MIX).ResultsThe LP and MIX silages had lowest pH (p<0.001) on 7 and 48 days, while MIX and CON silages had greatest lactate concentrations (p<0.05) on 7 and 48 days, respectively. Acetate concentrations were highest (p<0.01) in LB and MIX silages on 7 days, and in LB silage on 48 days, while lactate to acetate ratios were lowest (p<0.001) in LB silages. The chemical compositions and nutrient digestibility of silage ensiled for 100 days was not affected by inoculants. On 100 days of ensiling, LB silage had lowest (p<0.01) lactate concentration and lactate to acetate ratio, but highest acetate concentration. Aerobic stability was highest (p<0.001) in LB silage followed in MIX silage. On contrast, LB silage had lowest (p<0.05) lactic acid bacteria and mold.ConclusionThe results indicated that application of LB solely had a better effect on aerobic stability than not only LP, but also MIX. However, LP application did not show beneficial effects from the viewpoints of fermentation quality and aerobic stability compared to CON.

“…Studies show that the use of sweet potato by-product in livestock diet is a promising reality, with great potential for application and positive effects as to weight gain, and organic matter consumption and digestibility (Megersa, Urge, & Nurfeta, 2013;Phesatcha & Wanapat, 2013;Beckford & Bartlett, 2015;Mangwe, Rangubhet, Mlambo, Yu, & Chiang, 2016;Dang et al, 2017;Li, Ji, Wang, Qin, Hou, & Shen, 2017;Kamiya et al, 2017), but few studies have assessed the effect of using sweet potato on ruminal pH; what has been proposed is the transformation of a residue, which is not commercialized, into flour or bran, in order to compose a balanced diet. Therefore, the objective of this study is to assess the ruminal pH of sheep supplemented with different levels of sweet potato byproduct.…”

The accumulation of industrial by-products increases the use of sweet potato waste for ruminants, but ruminal pH characteristics are still not well known. The objective was to assess the fluctuation of ruminal pH in sheep supplemented with different levels of sweet potato flour inclusion in their diet. Four rumen-fistulated sheep were used; they were fed a diet based on ryegrass haylage (Lolium multiflorum) and sweet potato flour (Ipomoea batatas), provided according to the level of inclusion in the total diet (0, 0.5, 1.0 and 1.5%). Approximately 80 ml of ruminal fluid was collected for reading on a bench pH meter. Statistical data analysis was run on Statistical Analysis System (SAS Institute INC. Cary, NC, USA), and statistical difference was considered for p < 0.05. The animals that received 1.5% of sweet potato flour in their diet presented acid rumen pH; the 1.0% group presented rumen pH acidification in the first 6 hours after feeding, and the 0.5% level of inclusion did not change the rumen environment. It is concluded that the inclusion of 0.5% sweet potato flour in sheep diet proved to be an efficient energy supplementation strategy.
