Summary: The research found that the addition of 20% and 40% of Acacia mearnsii negatively affected the digestion of nutrients in ruminants, but reduced methane production. This may be associated with the low activity of microorganisms towards the substrate due to the possible tannin/nutrient complex.

Summary: Tannin has been extensively assessed as a ruminant feed additive, but the effects of extracted forms on ruminants are inconclusive. Increasing tannin extract inclusion in the diet reduces ruminant intake, digestibility, and production performance, as well as decreasing animal N utilization. HT is more favorable in maintaining nutrient intake, digestibility, production performance, and mitigating methane emissions compared to CT.

Summary: The response of biogas microbiome to a gradual increase in organic loading rate by supplementing with Na-Oleate led to the formation of three clusters describing microbial behaviors. The dominance of Candidatus Methanoculleus thermohydrogenotrophicum in reactors fed with cattle manure indicated a hydrogenotrophic methanogenic pathway, further enhanced by lipid supplementation. Shift back to solely cattle manure altered microbial dynamics significantly, with a notable increase in a propionate degrader affiliated to the order of Bacteroidales becoming the predominant microorganism.

Summary: A multi-channel, non-thermolytic, and efficient pathway was developed to synthesize functionalized carbon nitride-like oligomers from cyanamide and glyoxal in aqueous media. The oligomers obtained showed stable solid forms and exhibited structures derived from cyanamide self-additions as well as from the condensation of cyanamide, dicyandiamide, or melamine with glyoxal. The formation of these oligomers was rationalized as the result of polyadditions of cyanamide and glyoxal.

Summary: This study investigated the effects of feeding condensed tannin-containing Sericea lespedeza hay on feed intake, digestion, growth performance, energy metabolism, and ruminal fermentation and methane emission in ruminants. The results showed that increasing the concentration of lespedeza in the diet decreased the digestion of fiber and nitrogen, resulting in reduced growth performance. However, the dietary concentration of lespedeza did not affect methane emission in goats or sheep. This suggests that feeding lespedeza has important effects on nitrogen digestion and growth performance in ruminants, but does not decrease methane emission. Further research is needed.

Summary: The study showed that dietary inclusion of sericea lespedeza has effects on the performance and rumen fermentation of small ruminants, decreasing total-tract digestibility and average daily gain, reducing acetate proportion but increasing butyrate and propionate proportions in the rumen. The optimal inclusion rate of sericea lespedeza in the diet should be no more than 60% to minimize negative effects on DMD and ADG.

Summary: The incorporation of Acacia mearnssi, which is rich in tannins, in the diet of ruminants reduces greenhouse gas production and may improve protein utilization. However, it also decreases the digestion of dry matter and organic matter, which affects animal production. The addition of up to 20% of A. mearnsii shows no significant changes in greenhouse gas emissions compared to traditional forages.

Summary: Methanogenesis is crucial in ruminant animal digestion, but the resulting methane emissions contribute significantly to greenhouse gas levels. Various strategies, including dietary modifications and feed additives, have been proposed to reduce methane emissions. However, more research is needed to validate their effectiveness and evaluate their safety and consumer acceptability.

Summary: Supplementation of FlaH may protect CP and starch from ruminal degradation without adversely affecting fibre degradation and VFA profiles. It also shows promising effects on reducing CH4 production by suppressing H-2 production. Protein enzymatic hydrolysates from BSG using flavourzyme show potential application to high value-added bio-products.

Summary: Wheat is an important source of minerals for a healthy diet, but the phytate complex in the grain makes some minerals unavailable to humans. Our trials compared different wheat species and bread-making recipes to find ways to reduce phytic acid content and increase mineral bioavailability. We found significant variations in mineral content and phytase activity among different wheat species and varieties. Bread-making recipes, such as long yeast proofing or the use of whole grain rye flour, had a greater impact on reducing phytic acid content in bread than the choice of wheat species. Collaborations between research organizations and stakeholders are necessary for optimizing food production for a growing world population.

Summary: The objective of this contribution is to summarize the optimal concentration of nonphytate phosphorus (NPP) in feed for laying hens from scientific literature. The data suggests that the NPP concentration in feed should not exceed 2.2 g NPP/kg without the use of phytase, as it shows no positive effect on performance and eggshell. The addition of phytase to the feed can reduce this value, but precise values of reduction cannot be calculated due to insufficient data.

Summary: The objective of this study was to evaluate an enzymatic laboratory method for estimating ruminal protein degradation, using in situ data as reference. Appropriate in vitro methods are important to overcome methodological and ethical shortcomings associated with the use of experimental animals. The results showed that additional carbohydrate-degrading enzymes should be used to improve the conformity of the laboratory method with in situ reference data.

Summary: This study investigated the effects of feeding increasing acacia gum on the apparent ileal and total tract digestibility of nutrients in growing pigs. The results showed that increasing acacia gum reduced the digestibility of dry matter and gross energy, but did not affect the digestibility of crude protein and amino acids. However, it decreased the total tract digestibility of phosphorus. Feeding fermentable, low-viscous acacia gum can affect the digestion of pigs, and the specific endogenous losses of phosphorus associated with it should be considered in evaluating phosphorus digestibility.

Summary: This study compared female turkeys and broilers at 6 weeks of age to assess the impact of species, dietary P, Ca, and phytase levels on InsP6 degradation, phosphatase activity, P and Ca digestibility, and myo-inositol concentrations. Different diets were fed to the animals for 7 days, and samples were collected from various parts of the digestive tract. The results showed differences in phytate degradation between turkeys and broilers, which could be attributed to age-related changes in the digestive tract.

Summary: Phytase supplementation is becoming important in animal nutrition due to its impact on phosphorus digestibility and the growing relevance of phosphorus for sustainable production. This review focuses on the interactions of zinc with phytate and phytase in the digestive tract of poultry and pigs, emphasizing the effects of zinc supplementation on phytase efficacy and phosphorus digestibility. In vitro studies show the inhibitory effect of zinc on phytase efficacy, but there is limited and inconsistent data from in vivo studies, possibly due to various factors and differences in methodology.
