“…The use of feed with high fiber content (i.e., pectin) has a tendency to increase ruminal pH as it stimulates the production of saliva which contains bicarbonate that increases ruminal pH [37]. Polyphenolic compounds also have a tendency to increase pH value in the rumen ecosystem [23]. Moreover, in Orzuna-Orzuna et al [38] study, feeding a diet rich in flavonoids increased the pH value.…”

“…Methane emission does not only affect the environment but also reduces feed efficiency as it is also linked with dietary energy loss [22]. Animal scientists have attempted to formulate diets with alternative feed components rich in plant bioactive compounds (e.g., polyphenols) in order to modulate the ruminal microbial populations' [23], to improve ruminal fermentation, reduce biohydrogenation processes of FA, mitigate methane emission as well as increase dairy cows' productivity. The hypothesis of this study is that, due to the high content of bioactive ingredients, apple pomace could modulate the population of microorganisms in the rumen, thus limiting methane emission and the biohydrogenation process.…”

Industrial fruit by-products are now being utilized as animal feeds for several reasons. They may substitute the conventional cereal feeds, and also offer economic and environmental benefits. One of the most important industrial fruit by-products is apple pomace, which can be used as a source of energy in the ration of ruminant species, including dairy cattle. The aim of the present study was to evaluate the effect of feeding dried apple pomace to dairy cattle on ruminal fermentation, fatty acid concentration, microbial populations, and methane production. The experiment lasted 64 days and was conducted with 4 cannulated commercial dairy cows. The control animals received a standard diet, while the experimental animals was fed a standard diet supplemented with 150 g/kg DM dried apple pomace. Ruminal fluid samples were collected at three different time intervals. The samples were obtained at 0-, 3-, and 6-h post-feeding. The ruminal fluid was used to assess the ammonia concentration, pH, volatile fatty acids (VFA), long-chain fatty acids (FA), microbial population. A number of ruminal fermentation variables changed as a result of the addition of dried apple pomace to the standard diet. Ruminal pH slightly increased (p < 0.01) while the ammonia concentration decreased (p < 0.01) by 46%. There was a significant decrease in total protozoa count (p < 0.01) and an increase (p < 0.01) in total volatile fatty acids. In addition, there was a decline in methane emission (p = 0.05) by 8% due to dried apple pomace feeding. To sum up, this study demonstrated a positive effect of 150 g/kg DM dietary dried apple pomace on ruminal metabolism including a decrease in ammonia concentration and methane emissions, alongside with an increase in total ruminal VFAs, higher nutrient digestibility, and milk production. Also, beneficial changes to the ruminal fatty acid profile resulting from reduced biohydrogenation were observed although a decreased content of the C18:2 cis 9 trans 11 isomer was also noticed. The dietary inclusion of DAP can serve as a valuable, sustainable, and environmentally friendly dietary component for dairy cows.

“…Phenolic compounds are plant secondary metabolites, and they may positively affect animal performance, stress mitigation, gut microflora development, and immune function (Formato et al 2022 ). Moreover, phenolic compounds show anti-inflammatory, antioxidant, antimicrobial, antimutagenic, and immunomodulatory properties in many organisms (Waqas et al 2023 ). Phenolic compounds, acquired from plants as a component of the cattle diet, may potentially play a vital role in animal health (Tsen et al 2014 ), and identification of these phenolic compounds would provide invaluable information about silage nutritional quality relevant to animal health (Xu et al 2020 , 2021 ).…”

Sorghum forage was ensiled for 90 days at two dry matter (DM) contents (27 vs. 39%) without or with Lactiplantibacillus plantarum inoculation. On day 90 of fermentation, silages were sampled to assess the microbial community dynamics and metabolome profile. L. plantarum inoculation improved silage quality, as shown by a lower pH and greater acetic acid concentration. Loss of DM remained unaffected by L. plantarum inoculation but was greater in low- vs. high-DM sorghum silages (14.4 vs. 6.62%). The microbiome analysis revealed that Pseudomonas congelans represented the dominant species of the epiphytic microbiota in both low- and high-DM sorghum forage before ensiling. However, L. buchneri represented the dominant species at the end of ensiling. Ensiling fermentation resulted in distinct metabolic changes in silages with varying DM content. In low-DM silages, ensiling fermentation led to the accumulation of 24 metabolites and a reduction in the relative concentration of 13 metabolites. In high-DM silages, ensiling fermentation resulted in an increase in the relative concentration of 26 metabolites but a decrease in the concentration of 8 metabolites. Compared to non-inoculated silages, L. plantarum inoculation resulted in an increased concentration of 3 metabolites and a reduced concentration of 5 metabolites in low-DM silages. Similarly, in high-DM silages, there was an elevation in the relative concentration of 3 metabolites, while a decrease in 7 other metabolites. Ten metabolites with bio-functional activity were identified, including chrysoeriol, isorhamnetin, petunidin 3-glucoside, apigenin, caffeic acid, gallic acid, p-coumaric acid, trans-cinnamic acid, herniarin, and 3,4-dihydroxy-trans-cinnamate. This study presents a comprehensive analysis of microbiome and metabolome profiling of sorghum forage during ensiling as a function of DM content and L. plantarum inoculation, with a particular emphasis on identifying metabolites that may possess bio-functional properties. Key points • DM loss was not different by L. plantarum but higher in low- vs. high-DM silage. • L. buchneri dominated ensiling, regardless of DM level. • 10 metabolites with bio-functional activity were identified.

“…Among these alternatives, the concept of tannin application has attracted great interest in dairy cow research due to their ability to affect several aspects of nutrition, such as feed intake, digestion, ruminal fermentation and methane emission (Orzuna-Orzuna et al, 2021), as well as to modulate oxidative stress response (Liu et al, 2013). The diet of dairy cows can be supplemented either with condensed or hydrolysable tannins, with the dietary effects differing depending on the source and/or their biological activity of individual tannins (Waqas et al, 2023). Dietary supplementation with tannins can enhance plasma antioxidant capacity, thereby reducing oxidative stress and proinflammatory cytokine profile, as evidenced by studies involving dairy cows (Liu et al, 2013;Santillo et al, 2022).…”
