“…They suggested that Lac, LiP, and MnP present in the extracts promoted in vitro rumen digestibility and boosted acid production [ 67 ]. Other authors also reported improvements in AF when pretreating corn silage [ 68 ] and corn bran [ 66 ] with Lac. The higher concentrations of SCOAs obtained in these works probably resulted from higher enzymatic activities of the extracts produced, since these were concentrated before being applied to the substrate.…”

Enzymatic Potential of Filamentous Fungi as a Biological Pretreatment for Acidogenic Fermentation of Coffee Waste

et al. 2022

Spent coffee grounds (SCGs) are a promising substrate that can be valorized by biotechnological processes, such as for short-chain organic acid (SCOA) production, but their complex structure implies the application of a pretreatment step to increase their biodegradability. Physicochemical pretreatments are widely studied but have multiple drawbacks. An alternative is the application of biological pretreatments that include using fungi Trametes versicolor and Paecilomyces variotii that naturally can degrade complex substrates such as SCGs. This study intended to compare acidic and basic hydrolysis and supercritical CO2 extraction with the application of these fungi. The highest concentration of SCOAs, 2.52 gCOD/L, was achieved after the acidification of SCGs pretreated with acid hydrolysis, but a very similar result, 2.44 gCOD/L, was obtained after submerged fermentation of SCGs by T. versicolor. This pretreatment also resulted in the best acidification degree, 48%, a very promising result compared to the 13% obtained with the control, untreated SCGs, highlighting the potential of biological pretreatments.

“…Additionally, there were no significant disparities in the relative flora abundance between groups at the phylum and genus levels, indicating that transportation had a minimal impact on the rumen bacterial structure and composition in goats. This variation could be attributed to the distinct rumen microbial communities present in cattle and goats [ 39 , 40 ]. According to Li et al [ 41 ], the rumen microbiota composition differs significantly between these two animal species.…”

The objective of this experiment was to delve into the impacts of transportation on goats. Sixteen healthy goats were selected as experimental animals; these goats were transported at a speed ranging from 35 to 45 km/h for 20 h. The changes in the physiological indexes, blood physiological indexes, biochemical indexes, rumen fermentation indexes, and rumen microbial structure composition of goats before and after transportation were measured. The results showed that after transportation, the contents of IgM, IgA, IgG, and Thyroxine decreased very significantly, while the contents of propionic acid, Hemoglobin and Epinephrine significantly increased, and the contents of VFA, acetic acid, butyric acid, isobutyric acid, isovaleric acid, LPS, IL-1β, IL-6, TNF-α, Major Acute Phase Protein, protein carbonyl, and cortisol increased very significantly. There was no significant difference in α-diversity and β-diversity, and the relative abundance of rumen microorganisms was not significantly different at either phylum or genus levels. The experimental findings revealed that continuous transportation for a duration of 20 h can induce a severe stress response in goats, leading to compromised immune function, diminished antioxidant capacity, escalated inflammatory response, and altered rumen fermentation indices. However, the experiment did not reveal any significant impact on the structure and composition of the rumen microbiota.

In the current study, we use 25 local Iraqi lambs. With initial body weight (24) kg. The lambs were randomly divided into five treated groups, the first group without treatment as control, the second and third treated with 20%and 40% Agricultural Waste treated with trade enzymes, fourth and fifth treatment 20%and 40% Agricultural Waste treated with local enzymes. The result demonstrated a significant (P<0.01) increase in the quantity of roughages, total feed intake, Neutral Detergent Fiber (NDF) and Acid Detergent Fiber( ADF) and Lignin (ADL) in T5 followed by T4 compared with others treated groups and showed a significant (P<0.01) increase in the digestibility of NDF ,ADF in T4, T5 compare with other treated groups. While T5and T4 recorded Superiority increase in weight gain, and significant improvement in economic cost efficiency with ratio improvement of 5.90, 5.97 % respectively
