OBJECTIVE Four lactic acid bacteria (LAB) strains isolated from common vetch, tall fescue and perennial ryegrass on the Tibetan Plateau were characterized, and their effects on the fermentation quality of Italian ryegrass (Lolium multiflorum Lam.) silage were studied. METHODS The four isolated strains and one commercial inoculant (G, Lactobacillus plantarum MTD-1) were evaluated using the aci...

This study aimed to investigate the effects of lactic acid bacteria (LAB) inoculants on fermentation quality, microbial compositions, and predicted functional profiles forage oat. The oat was inoculated with distilled water, Lentilactobacillus buchneri (LB), Lactiplantibacillus plantarum (LP) as control (CON), LB LP treatments, respectively, addition (LB) or resulted in 1 × 106 colony-forming u...

To develop a new high-protein woody forage resource for livestock to alleviate feed shortages in the tropics, we applied PacBio single-molecule, real-time (SMRT) sequencing explore community structure, species diversity and metabolic gene clusters of natural microorganisms associated with paper mulberry (PM) silage fermentation. High levels microbial abundance were observed PM raw material, the...

A series of in vitro fermentation experiments was performed to assess the effects of 4 feed enzyme products (FE) that varied in enzymatic activities on the degradation of alfalfa hay and corn silage. The FE contained a range of endoglucanase, exoglucanase, xylanase, and protease activities, and a range of dose rates (DR) was used. The objective of the study was to identify effective formulation...

An experiment was conducted with 20 Arabi lambs to study the effect of ensiling time on the nutritive value of wheat straw. Two silages containing 3% urea and 10% molasses, made at early and late summer, were compared in this experiment. Both silages were fed to lambs supplemented with two levels of concentrates. Results showed that ensiling straw at late summer seemed to produce better silage ...

The effects of direct-cut and wilted silage with or without rapeseed meal (RSM) supplementation on rumen fermentation and digesta passage rates were studied in a 4 4 balanced Latin square experiment with four multiparous cows. The dry matter (DM) and crude protein (CP) degradabilities of silages were determined in sacco. RSM supplementation replaced 16% of the oat±barley concentrate mixture. Th...

Two experiments were conducted to investigate the effects of a Saccharomyces cerevisiae fermentation product (XP, Diamond V, Cedar Rapids, IA) on in vitro ruminal fermentation of single forage and mixed diets. In Exp. 1, an in vitro test was used to determine the effects of various concentrations (0, 1, 2, and 3 g/L) of XP on ruminal fermentation of the major forage sources of China (rice straw...

Several feed preservation methods can ensure lower mycotoxin contamination levels enter the food life cycle, and a relatively common wet method of forage plant materials is fermentation. This study aimed to characterize microbiological state fermented silages haylages (corn, alfalfa, rye, triticale), their main microbiota, isolation bacteria with resistance. Bacteria that remain viable througho...

This study aimed to investigate the effects of low-temperature-tolerant lactic acid bacteria on fermentation quality and bacterial community oat silage. Silage treatments were designed as control (with no additives), with FO3, FO5, FO8, L214 inoculants. After 60 days ensiling, characteristics analyzed. The results showed that able reduce pH NH3-N increase crude protein contents. It is worth not...
