Summary: Reducing dietary crude protein levels is a nutritional strategy recognized to decrease environmental impacts, by reducing the use of high-impact feed ingredients, altering manure composition, and lowering emissions of harmful components. Feed-grade amino acid supplementation plays a crucial role in maintaining animal performance.

Summary: This experiment aimed to determine whether adding gelatin and vitamin E to the diet of male Cobb broilers vaccinated for coccidiosis can alleviate impaired performance. The results showed that vaccination negatively affected performance in the first 21 days, but the inclusion of gelatin and vitamin E reduced this negative response and improved performance. Additionally, vaccinated chickens had increased pro-inflammatory immune status and mucin expression compared to broilers receiving salinomycin.

Summary: The study evaluated the effects of enterocin (Ent)7420 and sage on rabbit meat quality and amino acid content. The results showed that combining Ent7420 with sage led to the highest protein levels in rabbit meat, as well as increased essential and non-essential amino acids in all experimental groups. Dietary inclusion of Ent7420 alone or in combination with sage improved rabbit meat quality.

Summary: Affective state can influence an animal's judgement, with animals in positive states showing more optimistic interpretations of ambiguous cues. This study found that broiler chickens in high-complexity environments displayed a more optimistic judgement bias, indicating that environmental complexity can improve their affective states. Additionally, birds in higher stocking density pens tended to approach all cues faster, possibly due to increased food motivation from resource competition.

Summary: The objective of this experiment was to compare the postprandial concentrations of plasma amino acids and other metabolites after the ingestion of amino acids provided either as proteins or as free amino acids and small peptides. It was found that the postprandial appearance of amino acids in the plasma was slower and lower when proteins were consumed, which may result in inefficient protein synthesis. Therefore, providing amino acids in the form of free amino acids and small peptides may be more efficient.

Summary: Our study demonstrates that extrusion can improve the nutritive values of full-fat rice bran and corn distillers dried grain with solubles by increasing the apparent total tract digestibility of nutrients and amino acids. This suggests that extrusion could be an effective strategy to enhance the nutritional quality of feed by-products.

Summary: The study reveals that the soil around hedges has higher concentrations and storage of SOC, with a significant portion stored in the labile particulate organic matter fraction within 0-30 cm depth. The estimates of SOC accumulation rates over 30 years after tree planting ranged from 0.034-0.096 Mg C yr(-1) per 100 linear m of hedge, indicating a stable trend.

Summary: Nitrous oxide, ammonia, and methane emissions from livestock manure management are important contributors to greenhouse gases. An international project called DATAMAN developed a global database to identify key variables influencing emissions and improve emission factors for national inventories. The field database focused on N2O and NH3 emissions from land-applied manure, with observations from studies in multiple countries and continents.

Summary: This study aimed to quantitatively evaluate six soil ecosystem services (SES) using a set of indicators derived from dynamic soil and crop modelling. The results revealed that soil variability plays a crucial role in providing SES, particularly for groundwater recharge, plant biomass provision, plant water provision, and carbon sequestration. These findings highlight the importance of soil properties in influencing the provision of ecosystem services.

Summary: The study found that Miscanthus ash had no significant impact on the survival, biomass, and reproduction of earthworms, but negative trends were observed for biomass from 2.5 t ha(-1) and for reproduction from 10 t ha(-1). Significant avoidance responses were observed in the 25 and 50 t ha(-1) treatment.

Summary: The study reveals the diversity of organic vegetable farming systems in France, indicating a snapshot of bifurcation with large differences among farm clusters. The findings suggest that structural factors play a role in the degree of conventionalisation or agroecology of organic vegetable farming, but there is variation in agroecological performances even within farms with similar structural factors. Further research is needed to explore the freedom to develop more agroecological organic practices within specific farm sizes or supply chains.

Summary: In response to sustainability issues in agriculture in advanced economies, there is a growing relevance of agroecology in scientific, political, and social debates. This article reviews the literature on farm transitions to agroecology in advanced economies, identifying key research challenges and suggesting innovative research paths. The findings suggest the need for research that includes farm-level exploration and definition of desired futures, more holistic and dynamic assessment frameworks, and a focus on the dynamics of change processes during transitions.

Summary: Biodiversity loss due to agricultural intensification and habitat degradation is a major concern, and current life cycle assessment (LCA) methods lack the ability to assess impacts on biodiversity in vegetable production systems. The SALCA-BD expert system was adapted to assess and compare biodiversity impacts in vegetable production systems by considering habitats and farming practices. The results highlighted the importance of semi-natural habitats and low-intensity practices for preserving biodiversity, and indicated that assessment at the farm level is more informative than at the field level.

Summary: Urgent action is needed to address the challenges faced by agriculture under climate change. This study assessed the effects of a conservation agriculture crop rotation on soil carbon sequestration, greenhouse gas emissions, and environmental impacts. Modelling over 100 years revealed that conservation agriculture resulted in soil carbon sequestration and a lower climate change impact compared to conventional agriculture.
