“…It has been noted that at pH values below 6.0, cellulolytic (Takizawa et al., 2020 ) and fibrolytic activities decline (Chiba, 2014 ). Additionally, the findings of Khattab and Anele ( 2022 ), which the results of this experiment support, indicated that raising the pH of rumen fluid from 5.94 to 6.31 increased the nutrients digestibility. In general, the presence of NPN sources enhances microbial protein synthesis, increasing degradability.…”

BackgroundAnnually, a massive amount of broiler litter (BL) is produced in the world, which causes soil and surface water pollution due to its high nitrogen content and microbial count. While ruminants can use this non‐protein nitrogen (NPN) source for microbial protein synthesis. This issue becomes more critical when protein sources are unavailable or very expensive. One of the sources of NPN is BL which is produced at a considerable amount in the world yearly.ObjectivesThis aim of this research was to conduct a survey of non‐thermal technologies such as electrocoagulation (EC), ultraviolet (UV) radiation, and ultrasound (US) waves on the microbial safety and nutritional value of BL samples as a protein source in ruminant diets.Materials and methodsThe methodology of this study was based on the use of an EC device with 24 V for 60 min, UV‐C light radiation (249 nm) for 1 and 10 min, and US waves with a frequency of 28 kHz for 5, 10 and 15 min to process BL samples compared with shade‐dried samples. Chemical composition and nutritional values of processed samples were determined by gas production technique and measurement of fermentation parameters in vitro.ResultsBased on the results, microbial safety increased in the samples processed with the US (15 min). The EC method had the best performance in reducing the number of fungi and mould. However, none of the methods could remove total bacteria and fungi. Digestibility of BL was similar in shade‐dried, EC, and US (10 min) treatments. In general, the use of EC and US15 without having adverse effects on gas production caused a decrease in the concentration of ammonia nitrogen. In contrast, it caused a decrease in neutral detergent fibre (NDF) in the investigated substrate.ConclusionsIn general, it can be concluded that the use of US5 and EC methods without having a negative effect on the parameters of gas production and fermentation in vitro, while reducing NDF, causes a significant reduction in the microbial load, pathogens, yeast, and mould. Therefore, it is suggested to use these two methods to improve feed digestibility for other protein and feed sources.

“…Lower degradation of CN could be attributed to higher NDF, phenols, and tannins, which confirm that the chemical composition of fodder shrubs affected the rumen microbiota and the ruminal degradation [33,34]. On the other hand, higher degradation in the atriplex could be attributed to higher content of non-protein nitrogen compounds [38]. Previous studies found that the rumen disappearance of the diet's nutrients was declined by the inclusion of acacia, leucaena, and atriplex in the animal diet [3,39].…”

Leguminous trees and saltbushes provide potential alternatives to conventional feeds to overcome feed deficiency in arid and semi-arid countries. However, these plants are rich in antinutritional factors that have adverse effects on rumen microbiota and the host- animal. Some rumen microbiota detoxifies plants’ secondary metabolites; thus, understanding plant-microbe interaction in the rumen could improve the plants’ utilization. This study investigated the bacterial colonization and degradation of non-extracted and extracted tanniniferous plants: Atriplex halimus, Acacia saligna, and Leucaena leucocephala, in the rumen of three fistulated camels at 6 and 12 hours. The results showed that these plants have high nutritional value and tannins contents. The rumen degradation and microbial diversity of plant-attached bacteria varied according to plant type and phenols’ extraction. Atriplex and leucaena showed higher microbial diversity at 6 and 12h, respectively. Bacteroidetes and Firmicutes were the main bacterial phyla, and the main genera were Prevotella, RC9_gut_group, Butyrivibrio that overrepresented in non-extracted plants (P<0.05). Fibrobacteres and Anaerovibrio showed sensitivity to plant toxins and Ruminococcus attached to plants with lower tannins. Several bacterial genera in the camel rumen have the potential to resist antinutritional factors in fodder plants, which could be used to improve the performance of grazing animals.

“…However, Abo-Donia et al (2019) reported that no significant increase in DMI was observed by dairy cows fed discarded dates. Also, no significant differences in DMI were found in sheep and lactating ewes fed discarded dates (Khattab, 2013;Khattab and Anele, 2022). Numerous studies have investigated the influence of discarded dates on nutrient digestion (Al-Yousef et al, 1994;Iqbal et al, 2019;Khattab et D al., 2013;Khattab and Anele, 2022;Shi et al, 2014;Taghinejad-Roudbaneh et al, 2015;Zade et al, 2014).…”

ates that have been discarded are rich and inexpensive source of energy and represent a promising replacement for costly concentrates in livestock feeding. This research evaluated the impact of increasing levels of discarded dates as a substitute for yellow corn grain on intake, nutrient digestibility, and performance of lactating Barki ewes. Twenty multiparous lactating ewes (38.2 kg ± 1.18) were randomly divided into four groups (five ewes per group). The feeding trial lasted for 60 days, followed by the digestion trials. Ewes were fed a diet of concentrate feed mixture and fresh berseem clover at 70:30 on dry matter basis. Discarded dates (DD) were introduced at levels of 0, 25, 50, and 75% as a replacement for corn grain (CG) in the concentrated feed mixture (CFM) of the experimental groups (R1; control, R2, R3, and R4), respectively. Replacement of CG with DD affected the chemical composition of the ration, resulting in an increase in crude fiber content and a decrease in crude protein content. However, DD had no influence on dry matter intake, nutrient digestibility coefficients, or nutritive values (TDN, DCP, and SE). Increasing the inclusion level of DD led to a significant improvement in digestible crude fiber content and a decrease in digestible N-free extract content. Actual daily milk yield and energy corrected milk were unaffected by DD. However, ewes fed on DD at 75% numerically produced less milk yield and milk constituent yields. Also, there was no significant effect of DD on ewes' BW or lambs' average daily gain. In conclusion, discarded dates can serve as an alternative energy resource for feeding lactating ewes up to 75% of yellow corn without any adverse effect on the animals' performance.
