Summary: The objective of this study was to assess the effect of adding two DFM formulations on fermentation kinetics, methane production, and feed degradation in two different basal feeds while validating a newly established IVGPT laboratory. The results showed no significant differences between the laboratories and no significant differences in the effects of the DFM within the feed type. However, adding the P2 DFM may have the potential to reduce methane production without affecting organic matter degradation.

Summary: Grass silage fermentation quality was not significantly affected by the use of acid-based additive or lactic acid bacteria. Addition of acid-based additive resulted in higher dry matter intake and increased butyrate molar proportion in the rumen. Barley preservation method influenced rumen bacterial community composition. Milk production was not affected by silage additive, but was slightly higher in cows fed dried barley compared to crimped and ensiled barley. Acid-based additive improved TMR stability and increased milk fat yield, while dried barley increased milk protein yield.

Summary: A shortage of high-quality roughage jeopardises the Chinese mutton sheep industry. The development of new roughage resources is important to safeguard the health and welfare of the sheep, to save costs, increase efficiency and improve resource utilization. The study found that using mulberry silage in the diet of Hu lambs promoted their growth and maintained satisfactory digestion. Replacing maize silage and soybean meal with mulberry silage had no effect on the feed intake and growth rate of Hu lambs. Rumen fermentation parameters and bacterial diversity were also affected by mulberry silage inclusion. This research is important for improving sheep feed formulation, enhancing resource utilization, and reducing environmental impact.

Summary: The aim of the experiment was to determine the optimal ratio between maize silage and grass-clover silage in lactating dairy cow diets. The evaluation was based on nutrient digestibility, rumen metabolism, and total carbon footprint. Four diets varying in proportions of grass-clover silage and maize silage were fed to lactating Holstein cows. The results showed that increasing the proportion of maize silage in the feed ration led to an increase in dry matter intake and a decrease in methane emission.

Summary: Hay milk is a traditional dairy product protected as traditional specialty guaranteed (TSG), with strict regulations to ensure authenticity. The study proposes two analytical approaches using GC-MS and HPLC-HRMS to differentiate milk containing silage, successfully predicting the use of maize or grass silage in cow's diet with 100% recognition. The findings suggest that analytical approaches based on HRMS are a viable authentication method for hay milk.

Summary: This study aimed to identify digestive traits that differed between bulls diverging in residual feed intake (RFI) and fed different diets, and to explore the hierarchy among digestive traits in discriminating RFI divergent bulls. The results showed that efficient bulls had lower rumen size, methane yield, number of cells in the ileal crypts, and a longer time of rumen pH below 5.8, as well as a lower proportion of small size particles in rumen content. The long-term RFI value was related to feeding behavior, rumen and abomasum size, and duration of ingestion events.

Summary: This study examined the effects of high sugar content diets from freshly stored or ensiled sugar beets on nutrient digestibility, rumen fermentation, microbial synthesis, and enteric methane emission in dairy cows. It also evaluated the methane mitigation potential of ensiled sugar beets with different nutrient compositions using an additive during ensiling. The results showed that the different diets had minimal effects on dry matter intake, methane production, and nutrient digestibility, but ensiled sugar beets had lower methane emissions compared to freshly stored beets.

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: 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: This study investigated the variation in amino acid (AA) digestibility and MEn of 18 samples of solvent-extracted soybean meal (SBM) in cecectomized laying hens. The results showed that the digestibility of SBM differed among AA, with ranges in digestibility of 6 to 12%-units for most AA. The precision of feed formulation benefits from considering the variations in AA digestibility and MEn.

Summary: This study investigated the effects of acacia and sainfoin as condensed tannin-rich sources on ruminal and manure methane emissions. The results showed that neither acacia nor sainfoin reduced the methane yield or emission intensity. Acacia supplementation reduced milk production and dry matter intake, while sainfoin reduced milk protein content and yield. Therefore, a careful evaluation is necessary before implementing tanniferous feeds in farm practice, as it may result in productivity losses.

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.
