“…Immediately, rumen uid samples were frozen at -80 ℃ until subsequent analyses. Volatile fatty acids (VFA) were determined by ion chromatography using a Dionex ICS-3000 ion chromatograph following the procedure mentioned by Li [23] and Seankamsorn [24]. Ammonium nitrogen (NH 3 -N) in rumen uid was determined by phenol-sodium hypochlorite colorimetric method [25] (TU-1810, Beijing Puxi General Instruments Co., Ltd.).…”

Background: Heat stress is a key issue of growing concern for livestock industry worldwide due to its negative effects not only on milk production, fertility, health, welfare, and economic returns of dairy cows, but also on the microbial communities in the rumen. However, the underlying relationship between rumen microbiome and its associated metabolism with heat tolerance in cow have not been extensively described yet. Therefore, the main objective of this study was to investigate differential heat resistance in Holstein cows using rumen microbiome and metabolome analyses.Methods: We performed both principal component analysis and membership function analysis to select 7 heat-tolerant (HT) and 7 heat-sensitive (HS) cows. The ruminal fluid samples of two groups were collected at two hours post feeding on 7th day of heat stress period, for analyses including rumen fermentation parameters, rumen microbiome and nontargeted metabolomics.Results: Under heat stress conditions, the HT cows had a significantly higher propionic acid content than the HS cows; whereas measures of the respiratory rate (RR), rectal temperature (RT), acetic,butyric acid and acetic acid to propionic acid ratio (A:P) in the HT cows were lower compared with the HS cows. Omics sequencing revealed that the relative abundance of Rikenellaceae_RC9_gut_group, Succiniclasticum, Ruminococcaceae_NK4A214_group and Christensenellaceae_R-7_group were significantly higher in the HT than HS cows; whereas Prevotella_1, Ruminococcaceae_UCG-014, and Shuttleworthia were significantly higher in the HS cows compared to HT cows. Substances mainly involved in carbohydrate metabolism, including glycerol, mannitol, and maltose, showed significantly higher content in the HT cows compared to that in the HS cows. Simultaneously, RR was significantly correlated with both differential microorganisms and distinct metabolites, suggesting three metabolites could be potential biomarkers for determining heat resistance that require further research.Conclusion: Overall, distinct changes in the rumen microbiome and metabolomics in the HT cows may be associated with better adaptability to heat stress. These findings suggest their use as diagnostic tools of heat tolerance in dairy cattle breeding schemes.

“…We performed such in vitro meta‐analysis of CHI, and the article had been published elsewhere (Harahap et al, 2020). After considering such criteria, 15 articles that composed of 21 experiments and 57 data points were included in the database (Araújo et al, 2015; De Paiva et al, 2017; Del Valle et al, 2017; Dias et al, 2017; Gandra et al, 2016; Garcia‐Rodriguez et al, 2015; Goiri, Oregui, & Garcia‐Rodriguez, 2010; Haraki et al, 2018; Henry et al, 2015; Kirwan et al, 2021; Mingoti et al, 2016; Seankamsorn et al, 2021; Vendramini et al, 2016; Zanferari et al, 2018; Zheng et al, 2021). Details of studies included in the meta‐analysis is presented in Table 1.…”

Chitosan (CHI) has been used as a feed additive in ruminant diets, but the effects obtained to date have been varied. This study aimed to evaluate the dietary addition of CHI on performance, nutrient utilization, and product characteristics of ruminants by using a meta-analysis approach. A total of 15 articles that composed of 21 studies and 57 data points were included in the database. Number of articles reported the effects of dietary CHI addition were six on beef cattle, seven on dairy cows, and two papers on sheep. Data analysis was based on the mixed model methodology, in which CHI addition levels were considered as fixed effects whereas different studies were treated as random effects. Results revealed that, across various studies, CHI decreased ruminal acetate proportion (p < 0.05) and increased propionate proportion (p < 0.01). Dry matter and crude protein digestibility were elevated due to CHI addition (p < 0.05). CHI decreased blood cholesterol level (p < 0.05) and increased monounsaturated fatty acid proportion in the milk (p < 0.05). However, CHI addition had no effect on dry matter intake, milk production, and milk efficiency of ruminants. In conclusion, CHI is able to modify rumen fermentation towards a favorable direction, but it limitedly affects performance of ruminants.

“…Because high-MW chitosan is mainly unable to penetrate through the cell membrane and cell wall, its potential antimicrobial activities or effects include preventing nutrients from being absorbed from cells extracellularly, altering cell permeability, and acting as a chelator of essential metals [ 54 , 56 ]. For the low-MW chitosan, apart from having an extracellular antimicrobial effect, it also has the intracellular antimicrobial effect, thereby affecting protein synthesis, mitochondrial function, and RNA [ 54 , 57 ]. Chitosan was reported to have a negative impact on the microorganisms [ 58 ].…”

Approximately 15–18% of crops losses occur as a result of animal pests, while weeds and microbial diseases cause 34 and 16% losses, respectively. Fungal pathogens cause about 70–80% losses in yield. The present strategies for plant disease control depend transcendently on agrochemicals that cause negative effects on the environment and humans. Nanotechnology can help by reducing the negative impact of the fungicides, such as enhancing the solubility of low water-soluble fungicides, increasing the shelf-life, and reducing toxicity, in a sustainable and eco-friendly manner. Despite many advantages of the utilization of nanoparticles, very few nanoparticle-based products have so far been produced in commercial quantities for agricultural purposes. The shortage of commercial uses may be associated with many factors, for example, a lack of pest crop host systems usage and the insufficient number of field trials. In some areas, nanotechnology has been advanced, and the best way to be in touch with the advances in nanotechnology in agriculture is to understand the major aspect of the research and to address the scientific gaps in order to facilitate the development which can provide a rationale of different nanoproducts in commercial quantity. In this review, we, therefore, described the properties and synthesis of nanoparticles, their utilization for plant pathogenic fungal disease control (either in the form of (a) nanoparticles alone, that act as a protectant or (b) in the form of a nanocarrier for different fungicides), nano-formulations of agro-nanofungicides, Zataria multiflora, and ginger essential oils to control plant pathogenic fungi, as well as the biosafety and limitations of the nanoparticles applications.
