“…A blood sample (approximately 10 mL) was obtained in tubes containing 12 mg of ethylene diamine tetra-acetic acid (EDTA) from the jugular vein. The plasma was isolated by centrifugation for 10 min at 500× g and preserved at − 20 °C until BUN analysis, according to Abdallah et al 62 . Approximately 200 mL of rumen fluid was collected from the rumen by a stomach tube connected to a vacuum pump.…”

Upgrading the nutritive value of rice straw (RS) is necessary to increase its contribution to enhancing meat and milk production. Present work verified whether novel Crabtree negative yeast inoculant could promote RS utilization, rumen fermentation, and milk quality in tropical crossbred lactating Holstein cows. The new stain of Crabtree negative yeasts (Pichia kudriavzevii KKU20 and Candida tropicalis KKU20) was isolated from the rumen of dairy cattle. This study used 6 multiparous crossbreds between Holstein Frisian × Zebu dairy cows in their mid-lactation period. Dairy cows were randomly allocated to three ensiled RS with various yeast stains including Saccharomyces cerevisiae, P. kudriavzevii KKU20, and C. tropicalis KKU20 according to a 3 × 3 replicated Latin square design. Crabtree-negative yeast (P. kudriavzevii and C. tropicalis) increased the apparent digestibility of dry matter by about 6.9% when compared with Crabtree-positive yeast (S. cerevisiae). Bacterial populations were highest with ensiled RS by C. tropicalis KKU20. Ensiled RS with Crabtree-negative yeasts were significantly increased with total volatile fatty acids, but they did not affect volatile fatty acid profiles. Milk protein precentage was highest at 35.6 g/kg when C. tropicalis was fed, and lowest when applied with S. cerevisiae and P. kudriavzevii KKU20 in ensiled RS at 34.5 and 34.1 g/kg, respectively. Thus, feeding ensiled RS with novel Crabtree negative yeast could improve RS digestion, rumen fermentation, and milk protein content in dairy cows.

“…However, due to their negative effects such as drug resistance and food safety concerns, other strategies have been attempted to improve animal growth performance and immune function [9]. For example, astragalus by-products had beneficial effects on rumen fermentation patterns and lipid metabolism in sheep, with no negative effects on their production performance and humoral immunity [10]. Direct feeding of probiotics to cows stabilizes rumen pH, the reduction in CH 4 production and the effect on the milk fatty acid profile of cows depending on strain type and diet formulation [11].…”

Antibiotics were once used in animal production to improve productivity and resistance to pathogenic microbiota. However, due to its negative effects, the search for a new class of substances that can replace its efficacy has become one of the urgent problems to be solved. Plant essential oils (EOs) as a natural feed additive can maintain microbiota homeostasis and improve animal performance. However, its specific mechanism of action needs to be further investigated. Therefore, we added different doses of essential oil of Zanthoxylum bungeanum (EOZB) to the diets of Small Tail Han Sheep hybrid male lambs (STH lambs) to evaluate the effect of EOZB on rumen enzyme activity, rumen microbiology, and its metabolites in STH lambs. Twenty STH lambs were randomly divided into four groups (n = 5/group) and provided with the same diet. The dietary treatments were as follows: basal diet (BD) group; BD+EOZB 5 ml/kg group; BD+EOZB 10 ml/kg group; BD+EOZB 15 ml/kg group. We found that EOZB 10 ml/kg helped to increase rumen pectinase (P<0.05) and lipase (P<0.05) activities. Microbial 16S rRNA gene analysis showed that EOZB significantly altered the abundance of rumen microbiota (P<0.05). LC/GC-MS metabolomic analysis showed that the addition of EOZB produced a total of 1073 differential metabolites, with 58 differential metabolites remaining after raising the screening criteria. These differential metabolites were mainly enriched in glycerophospholipid metabolism, choline metabolism in cancer, retrograde endocannabinoid signaling, benzoxazinoid biosynthesis, and protein digestion and absorption. Correlation analysis showed that some rumen microbiota were significantly correlated with differential metabolite and enzyme activities.

“…Notably, due to the limitations of current extraction procedures, Chinese herbal medicine residues still contain many bioactive substances such as avonoids and polysaccharides [3,4]. Therefore, disposing of these solid wastes through land lls or incineration is not only an enormous environmental burden but also a waste of valuable resources with therapeutic potential [5][6][7]. Therefore, there is a growing interest to repurpose these Chinese herbal medicine waste products by recycling these biomass resources in an effective environmentally-friendly manner [8].…”

Background: For the last few years huge quantity of herb residues are discharged in China, and so far there is not a good solution. The current methods of disposal and utilization of herb residues (stacking, incineration, and landfill) were not only great harmful to the ecological environment, but also cause the waste of medicinal herb resources. The fermentation can further decompose and transform the active ingredients and nutrients in herb residue, so the fermentation technology has good application prospect in the treatment of herb residues. In this study, we investigated the applicability of fermentation processes with the Aspergillus niger (ACCC 30583) strain for the reuse of Astragali Radix residues (ARR) by comparing the content changes of its nine constituents before and after fermentation. The contents of total protein and crude fat in the ARR were determined via near-infrared scanning; the iron, copper, zinc, and manganese contents were assayed with atomic absorption spectroscopy, the calycosin-7-glucoside and astragaloside Ⅳ content were determined by HPLC, and the polysaccharide content was determined via phenol sulfuric acid spectrophotometry. Results: The optimum fermentation conditions for ARR with ACCC 30583 was culture medium content 60%, fermentation time 5 days, and fermentation temperature 28 ℃. Compared with the residues before fermentation, the contents of total protein, calycosin-7-glucoside, astragaloside Ⅳ, Astragali Radix polysaccharides (ARP), and manganese increased significantly, the iron content decreased significantly, and the crude fat, zinc, and copper contents exhibited no significant changes. Conclusions: The solid fermentation of ARR with the Aspergillus niger (ACCC 30583) strain effectively promoted the separation of astragaloside Ⅳ and ARP from ARR, which provided methodological basis for the effective reuse of herb residues.
