A review of genetic resources and trends of omics applications in donkey research: focus on China

Frontiers in Veterinary Science, Journal Year: 2024, Volume and Issue: 11

Published: Oct. 11, 2024

Omics methodologies, such as genomics, transcriptomics, proteomics, metabolomics, lipidomics and microbiomics, have revolutionized biological research by allowing comprehensive molecular analysis in livestock animals. However, despite being widely used various animal species, on donkeys has been notably scarce. China, renowned for its rich history donkey husbandry, plays a pivotal role their conservation utilization. China boasts 24 distinct breeds, necessitating efforts, especially smaller breeds facing extinction threats. So far, omics approaches employed studies of milk meat, shedding light composition quality. Similarly, methods utilized to explore the basis associated with growth, meat production, quality traits. also unraveled critical microbiota health nutrition, gut microbiome revealing associations factors pregnancy, age, transportation stress, altitude. Furthermore, applications addressed issues, including infectious diseases reproductive problems. In addition, these provided insights into improvement efficiency research. conclusion, methodologies are essential advancing knowledge about donkeys, genetic diversity, across domains. is still infancy, there need continued enhance breeding, welfare beyond.

Advances in Donkey Disease Surveillance and Microbiome Characterization in China

Microorganisms, Journal Year: 2025, Volume and Issue: 13(4), P. 749 - 749

Published: March 26, 2025

This review article highlights the surveillance of bacterial, viral, and parasitic diseases in donkey populations China. Key findings highlight significant threats from Equine herpesviruses (EHV-8 EHV-1), which cause encephalitis, abortion, respiratory distress. Several infections including Giardia duodenalis, Cryptosporidium spp., Enterocytozoon bieneusi, Toxoplasma gondii present important zoonotic concerns across multiple regions Additionally, this synthesizes current knowledge on microbiota various body sites examines their functional significance health disease. The complex relationship between host represents a critical area research donkeys. Recent molecular advancements have enhanced our understanding diverse microbial ecosystems inhabiting different donkeys profound impact outcomes. As single-stomach herbivores, possess communities throughout digestive tracts that are essential for intestinal homeostasis nutritional processing. Significant variations composition exist segments, with hindgut displaying greater richness diversity compared to foregut. Beyond system, distinct profiles been characterized skin, oral cavity, reproductive tract, secretions such as milk. implications extend areas nutrition, immune function, disease susceptibility. Research demonstrates how dietary interventions, environmental stressors, physiological states significantly alter communities, correlating changes inflammatory markers, antioxidant responses, metabolic functions. specific signatures associated conditions like endometritis suggest potential microbiota-based diagnostics therapeutics. identification antibiotic-resistant strains Proteus mirabilis Klebsiella pneumoniae meat food safety requiring monitoring systems standardized protocols. These provide foundation improved healthcare management, targeted surveillance, protective measures those working or consuming donkey-derived products.

Cecal Microbial Diversity and Metabolome Reveal a Reduction in Growth Due to Oxidative Stress Caused by a Low-Energy Diet in Donkeys

Antioxidants, Journal Year: 2024, Volume and Issue: 13(11), P. 1377 - 1377

Published: Nov. 11, 2024

Dietary energy level plays an important role in animal growth and development. The present study investigated the effect of dietary on performance, antioxidative state, nutrient digestion meat donkeys. It simultaneously explored probable reason for cecal microbiota metabolome. Twelve donkeys (male) aged 1 year with a similar weight (150 ± 25 kg) were divided into two treatment groups: low-energy group (E1) high-energy (E2). experiment was 10-day pre-trial period 135-day trial period. Donkeys periods fed diets digestible values (in dry matter) 12.08 13.38 MJ/kg (pre-fattening, 1–45 d), 13.01 14.27 (mid-fattening, 46–90 13.54 14.93 (late-fattening, 91–135 d). results show that E1 decreases body weight, average daily gain (ADG), digestibility crude protein, ether extract, neutral detergent fiber, acid fiber (p < 0.05), but increases acetate butyrate concentrations, non-esterified fatty acids (NEFAs) serum, ratio matter intake to ADG(F/G). diminished activities catalase glutathione peroxidase, while it increased content interleukin, tumor necrosis factor-alpha, reactive oxygen species (ROS) 0.05). Cecal microbiome showed abundance Firmicutes Actinobacteria significantly lower than E2 = 0.029, p 0.002), whereas Bacteroidetes higher 0.005). genera Ruminococcaceae-UCG-004, Acinetobacter, Rikenellaceae_RC9_gut_group. Meanwhile, metabolome formyl-5-hydroxykynurenamine, chorismate, 3-sulfinoalanine, 3-isopropylmalate upregulated E1, brassinolide downregulated. altered metabolites mainly enriched metabolic pathways related metabolism mitigate oxidative stress donkeys, such as tryptophan metabolism, brassinosteroid biosynthesis etc. In conclusion, resulted negative balance resulting more nutrients being oxidized provide energy, inducing stress, thereby leading decreasing growth. reduction donkey from changes cecum metabolites.

In Vitro Evaluation of Chito-Oligosaccharides on Disappearance Rate of Nutrients, Rumen Fermentation Parameters, and Micro-Flora of Beef Cattle

Animals, Journal Year: 2024, Volume and Issue: 14(11), P. 1657 - 1657

Published: May 31, 2024

The study aimed to investigate the effect of dietary chitosan oligosaccharides (COS) meal levels on nutrient disappearance rate, rumen fermentation, and microflora beef cattle in vitro. A total 24 fermentation tanks were randomly divided into four treatments containing 0% COS (CON), 0.02% COS, 0.04% 0.08% for an 8-day experiment period, with each treatment comprising six replicates. disappear rates DM, CP, EE, gas production quadratically increased increasing levels. ADF greatest, whereas was lowest group. pH, NH3-N, MCP, content propionate, isobutyrate, butyrate, valerate, A/P levels, while linearly decreased. butyrate highest, NH3-N acetate, Microbiomics analysis showed that microbial diversity not altered between CON However, relative abundance Methanosphaera, Ruminococcus, Endomicrobium, Eubacterium groups increased, pathogenic bacteria Dorea Escherichia-Shigella a decrease Overall, most effective among three addition resulting increase rate vitro fermented nutrients improvements indexes communities. This, turn, led maintenance health.
