Summary: Feed use efficiency and N and P use efficiency are key indicators for evaluating the profitability and environmental performance of grassland-based dairy farms. This study revealed significant variations in these indicators among different farms, which were closely related to factors such as milk yield and feed composition. The findings provide valuable insights for improving the profitability and environmental performance of grassland-based dairy farms.

Summary: This study investigated the effects of offering concentrates on a feed-to-yield basis to dairy cows on milk yield, intake, milk composition, and production efficiency. The results showed that increasing milk yield resulted in lower fat and protein concentrations in the milk, but improved nitrogen and energy use efficiency. This has important implications for farmers supplying milk for processing as milk pricing mechanisms are often based on milk composition.

Summary: This study examines labor time-use on pasture-based dairy farms during the spring and summer seasons. The results show that total hours of labor input increase with herd size, and milking is the most time-consuming task. Labor efficiency improves with larger herd sizes.

Summary: This study compares the rumen bacterial community in dairy cows with different nitrogen utilization efficiency. The results show that there are differences in rumen bacterial diversity and relative abundance among cows with different NUE, indicating that the rumen bacteriome plays an important role in nitrogen metabolism in dairy cows.

Summary: Global dairy production has a significant impact on the emission of nitrogen and phosphorus into the environment. However, there are differences in performance among different dairy farming systems, and these differences are not well understood. In emerging market economies like China, dairy production is growing, and new dairy farms are large, intensive, and occupy limited farmland.

Summary: The response of crop yields to fertilizers is an important topic in agricultural production. A study conducted in dairy-pasture systems in South Africa found that high nitrogen fertilizer rates did not necessarily lead to higher pasture yields. Additionally, the nitrogen use efficiency of pastures improved with reduced fertilizer application rates.

Summary: Nitrogen is essential for crop growth and yield, especially for crops like pearl millet grown in dry and low fertility soils. Through evaluating 380 diverse pearl millet lines, some genotypes were identified with improved yield performance under low nitrogen conditions, providing insights for further research on nitrogen use efficiency.

Summary: The study examines labour time-use and the impact of specific facilities and technologies on labour demand in pasture-based dairy farms. Results show an increase in farm labour input and herd size, but also an improvement in labour efficiency. Farms that made changes to milking and calf care facilities showed significant improvements in milking efficiency and reduced labour input.

Summary: In this paper, the trade-offs and synergies between increasing dairy farm productivity and mitigating greenhouse gases emissions in pasture based dairy farms in Brazil are assessed. The results show that farmers can improve production by 9.4% while simultaneously reducing methane emissions by 8.7% on average. The adoption of more productive cows and improved pastures have a positive effect on environmental efficiency.

Summary: Dairy farms located in villages in China are an important sector in milk production. The development of village-based mixed livestock-crop systems can improve feed self-sufficiency, nutrient recycling, and reduce chemical fertilizer requirements, leading to increased crop productivity and benefit-cost ratio.

Summary: The study assessed the agreement between three common methods for measuring on-farm antimicrobial use with a reference method on UK dairy farms. Veterinary sales data showed excellent reliability for certain types of antimicrobials, while medicine waste bins had good to excellent reliability for others. Farm medicine records did not show agreement for any form of antimicrobial when compared with the reference method.

Summary: Due to its genetic diversity and resilience, barley is valuable for agroecological transition and reducing nitrogen fertilizer inputs. Studying the diversity of a North African barley collection under limited or ample nitrogen supply, as well as physiological traits, provides important insights into its response to nitrogen limitation during early developmental stages.

Summary: The study found that if laggard farmers adopted the best practices, they could increase their average annual gross profit by 34% and simultaneously reduce the N surplus by 50% during the time period, which is a win-win situation for farmers and the environment.
