“…Therefore, the selection of specific bacteria strains could mitigate climate-altering gas emissions from ruminants by acting through competitive inhibition of methanogenic microorganisms in the rumen. In addition, probiotics are also able to improve the bioavailability of microbes, as well as digestive capacity, and reduce ruminal pH and lactate levels [ 20 ]. The beneficial effects of probiotic supplementation in ruminants, especially in growing animals, is also related to the possibility of replacing antibiotic with prebiotics due to their effects for protecting gut microbiota [ 20 ].…”

An important challenge for livestock systems is the mitigation of environmental impacts while ensuring food security, and feed additives are considered as one of the most promising mitigation strategies. This study analyzed the innovation landscape of feed additives to reduce methane emissions in ruminants. The analysis is based on patent data to evaluate the development, scientific importance, and market-level impact of the innovations in this field. The results reveal that the EU is on the innovation frontier, with substantial and quality patent production. The innovation field is dominated by private players, characterized by high specificity in the R&D pipeline. Additives derived from plant or botanical extracts, together with 3-nitrooxypropanol (3-NOP), represent the emerging innovations, indicating a clear orientation toward more sustainable livestock systems. Despite the regulatory and semantic limitations related to the use of patent databases, data reveal a growing innovation activity at global level, which could lead to macroeconomic benefits for the entire livestock sector.

“…Mechanism of action of probiotics by which they exhibit beneficial effects is still not clear. Thus, more definitive research is needed to select the most effective strains of probiotics and their cost-benefit analysis [Kulkarni et al 2022]. The most important publications on the effectiveness of selected probiotics in ruminant nutrition are presented in Table 1.…”

The review article provides up-to-date scientific information on the characteristics, classification and mechanisms of biological action of pro-, pre- and synbiotics in the digestive tract of ruminants. The literature sources of recent years on the influence of pro-, pre- and synbiotic supplements (when adding them to the diets of ruminants) on the metabolic processes in the body, intensity of growth, development and the quality of products obtained from domestic ruminant animals are systematized and analyzed. Emphasis is placed on the fact that the degree of metabolic and productive action of these diet supplements in ruminants is determined primarily by the qualitative composition, technology of production, method of storage and quantity added to fodder. It is noted that the main mechanism of pro-, pre- and synbiotics action when entering the digestive tract of ruminant animals is optimizing the composition of its microflora, strengthening the barrier functions of the rumen, reticulum, omasum, abomasum and intestine, as well as activation of interferon synthesis by blood leukocytes, stimulation of digestive functions and strengthening immune status. Also it is stated that the use of these fodder additives in the diet optimizes the quantitative and qualitative composition of the symbiotic microbiota of the digestive tract, has an immunostimulatory effect, activates metabolic processes and improves the productive qualities of ruminants.

“…These genera have been identi ed as probiotics with immune-boosting potential in humans, sh and chicken(Li et al, 2006;Lee et al, 2012). Probiotics in ruminants in uence enzyme production leading to e cient digestion of nutrients, improved growth and performance and robust immunity(Arowolo and He, 2018;Idowu et al, 2022;Kulkarni et al, 2022). In this sense, greater relative abundance of Weissella, PeH15 and Arthrobacter in the rumen of low-RFI group suggest a possible role in activation and initialization of immunomodulatory properties, improved growth,…”

We investigated whole blood and hepatic mRNA expressions of immune genes and rumen microbiome of crossbred beef steers with divergent residual feed intake phenotype to identify relevant biological processes underpinning feed efficiency in beef cattle. Low-RFI beef steers (n = 20; RFI = − 1.83 kg/d) and high-RFI beef steers (n = 20; RFI = + 2.12kg/d) were selected from a group of 108 growing crossbred beef steers (average BW = 282 ± 30.4 kg) fed a high-forage total mixed ration after a 70-d performance testing period. At the end of the 70-d testing period, liver biopsies and blood samples were collected for total RNA extraction and cDNA synthesis. Rumen fluid samples were also collected for analysis of the rumen microbial community. The mRNA expression of 84 genes related to innate and adaptive immunity was analyzed using pathway-focused PCR-based arrays. Differentially expressed genes were determined using P-value ≤ 0.05 and fold change (FC) ≥ 1.5 (in whole blood) or ≥ 2.0 (in liver). Gene ontology analysis of the differentially expressed genes revealed that pathways related to pattern recognition receptor activity, positive regulation of phagocytosis, positive regulation of vitamin metabolic process, vascular endothelial growth factor production, positive regulation of epithelial tube formation and T-helper cell differentiation were significantly enriched (FDR < 0.05) in low-RFI steers. In the rumen, the relative abundance of PeH15, Arthrobacter, Moryella, Weissella and Muribaculaceae was enriched in low-RFI steers, while Methanobrevibacter, Bacteroidales_BS11_gut_group, Bacteroides and Clostridium_sensu_stricto_1 were reduced. In conclusion, our study found that low-RFI beef steers exhibit increased mRNA expression of genes related to immune cell functions in whole blood and liver tissues, specifically those involved in pathogen recognition and phagocytosis regulation. Additionally, these low-RFI steers showed differences in relative abundance of some microbial taxa which may partially account for their improved feed efficiency compared to high-RFI steers.
