Summary: The interseeding of alfalfa into corn can increase rotation productivity and reduce negative environmental impacts, but additional nitrogen fertilizer is required to maximize corn silage yield. The competition for nitrogen between corn and interseeded alfalfa can affect silage yield, but interseeded alfalfa may result in higher forage yield in the subsequent year. Split nitrogen application does not significantly influence corn or alfalfa responses, and further refinement of fertilizer and crop management practices is crucial for maximizing the forage production potential of this system.

Summary: This study compared the nitrogen recycling and use efficiency between Miscanthus x giganteus and Miscanthus sinensis. The results showed that Miscanthus x giganteus had higher endogenous net nitrogen fluxes than Miscanthus sinensis. However, the nitrogen recycling efficiency did not significantly differ between the two species. The study also found that external nitrogen sources, such as fertilization and organic matter mineralization, were the main contributors to the plant nitrogen content, and a certain amount of nitrogen was lost during winter, with only a small portion attributed to abscised leaves.

Summary: In citrus orchards in central China, reducing N fertilizer input and planting green manure are dominant measures for improving N use efficiency. This study found that reducing N fertilizer input can decrease total N losses but increase total P losses. Planting green manure can reduce total N losses but increase both total N and P losses during the ground mulching stage.

Summary: Zeolites are porous aluminosilicates with a crystalline structure that can be used for environmental purification and plant nutrition. Their high adsorption capacity, ion exchange, and specific surface area are the reasons for their wide application in agriculture. Direct application of zeolites in soil is beneficial for soil, reduces acidification, and improves nutrient use efficiency.

Summary: The study investigated the effect of different forage species, parity, milking time, and days in milk on milk fatty acid profile and transfer efficiency in dairy cows. The results showed that forage sources such as red clover and white clover increased health-promoting fatty acid components, while tall fescue increased the proportion of CLA in milk.

Summary: The study aimed to determine protein characteristics in different barley, corn, and sorghum cultivars, focusing on protein subfractionation and in situ ruminal protein degradability. Barley showed superior characteristics in terms of protein degradation rate and extent compared to corn and sorghum, with different FTIR protein molecular structures.

Summary: This study evaluated the complete substitution of silage pulp (SP) for grass-clover silage in the diet of dairy cows and its impact on milk production. The results showed that cows receiving the silage-based diet had higher milk yield and energy corrected milk compared to those receiving the SP-based diet. Additionally, the silage-based diet led to higher milk protein and milk fat yields. However, diets did not significantly affect milk composition, body condition score, or body weight.

Summary: This study investigated the effects of anaerobic fungi supernatant and mixed ruminal fluid as additives on the quality and ruminal fiber degradability of silages. The results showed that anaerobic fungi supernatant improved the quality of grass and straw silages, while mixed ruminal fluid enhanced lactic acid fermentation in grass silage. Both additives improved silage quality, but only anaerobic fungi supernatant enhanced ruminal fiber degradability of grass silage.

Summary: This study compared the effects of four different functional groups of cover crops on nitrogen immobilization, mineralization dynamics, nitrogen uptake, and biomass accumulation of subsequent silage maize. The results showed that cover crops significantly reduced soil mineral nitrogen and increased nitrogen uptake in maize. Among them, radish cover crop had the greatest net benefits for silage maize cropping systems.

Summary: The study developed an innovative nutrient recommendation approach, Nutrient Expert (NE), to optimize fertilizer use and improve crop yield, particularly for maize, wheat, and rice in China. NE outperformed current farmer practices and soil test-based fertilizer application in terms of yield improvement, profit increase, and reduced nitrogen losses and greenhouse gas emissions.

Summary: The present study compared the effect of whole crop faba bean silage with grass silage on lactating dairy cows and the milk production response of faba bean crude protein to that derived from a rapeseed meal supplement. The results showed that using faba bean silage increased feed intake and milk yield of cows, but the crude protein supply from faba bean silage was not as valuable as that from rapeseed meal.

Summary: There is growing interest in Europe in exploiting alternative native energy and protein feedstuffs for self-sufficiency and sustainability. However, there is limited research on oats, field beans, or peas as feed ingredients for beef cattle, especially as supplements to grass silage. This study found that including flaked beans and peas as supplements to grass silage had similar feeding value to maize gluten feed and maize dried distillers grains. Excluding protein ingredients from cereal-based concentrate did not affect animal performance and reduced nitrogen excretion.

Summary: There is an urgent need to reduce the environmental risk of pesticide pollution worldwide. We explored national leverage points and found that differences in countries' agricultural systems and policies contribute to a third of the global cross-country differences in pesticide pollution risk. Pesticide regulations, organic farming, and crop types are the main leverage points for policies.

Summary: The purpose of this research is to study the contribution of epiphytic microbiota in fresh oat, Italian ryegrass, and whole-crop maize to silage fermentation products and bacterial community structure of maize. The results showed that the microbiota epiphytic on maize had a significant impact on the quality of silage fermentation products and the composition of bacterial community.

Summary: This study evaluated the effects of diets containing vitiviniculture waste on intake, digestibility, water balance, nitrogen balance, ingestive behavior, performance, and carcass traits of lambs. The results showed that feeding lambs with diets containing 216 g/kg cactus pear and 144 g/kg vitiviniculture waste resulted in higher intake and digestibility.

Summary: This study evaluated the efficacy of a novel phytase in terms of phytate hydrolysis and the digestibility of phosphorus and calcium in broiler chickens fed low and high phytate diets. The results showed that the phytase effectively hydrolyzed phytate and increased digestible phosphorus and calcium. The response to dietary phytate varied in terms of age and the specific nutrient being evaluated.
