Summary: The concentration of crude protein in the basal diet has an influence on the accurate determination of metabolizable energy of a test ingredient. This study found that both the crude protein concentrations in the basal diet and test ingredients affect the metabolizable energy of full-fat soybeans and soy protein isolate. Additionally, the concentration of crude protein in the basal diet affects urinary energy output.

Summary: Two experiments were conducted to evaluate the effect of electron-beam irradiation of canola seed on broiler chickens. The results showed that irradiation reduced undesirable components and improved feed conversion rate. Therefore, irradiation can be helpful when using high levels of canola seed in broiler chicken diets.

Summary: Enzymatic treatment can improve the nutrient value of canola meal by depolymerizing nonstarch polysaccharides and mitigating its antinutritive properties. The treatment also decreases slurry pH, increases lactic acid production, and reduces simple sugars concentration. The enzymatic modification significantly increases the nitrogen-corrected apparent metabolizable energy of canola meal for broiler chickens.

Summary: This study found that long-term conditioning and expansion of full-fat soybeans can enhance metabolizable energy and amino acid digestibility, but extending the time and energy input beyond a certain point does not provide additional benefits.

Summary: The removal of snow-cover reduces soil nutrients, enzyme activities, and bacterial diversity in the desert ecosystem. Nitrogen deposition indirectly affects the bacterial community through modifications to soil nutrients and organic matter. This study highlights the critical role of snow-cover and raises awareness of the ecological risks of biological soil crusts in future global change.

Summary: Soil carbon sequestration is important for mitigating climate change. Nitrogen deposition affects soil carbon dynamics by altering carbon input and output. This study investigated the impact of nitrogen addition on soil carbon stocks and identified the mechanisms in an alpine meadow. After six years of nitrogen addition, the total carbon stocks in the topsoil significantly increased, with microbial biomass carbon content playing a key role. Nitrogen addition also affected aboveground biomass and organic matter decomposition.

Summary: This study investigates the effects of nitrogen and phosphorus addition on soil microbial functions and nutrient cycling in a meadow steppe, revealing that nitrogen addition alleviates microbial demand for nitrogen but increases microbial carbon limitation and soil nitrogen loss potential. Phosphorus addition, on the other hand, suppresses the abundance of ammonia oxidizing bacteria and soil nitrogen loss potential. The abundance of ammonia oxidizing bacteria and denitrifier genes in soils showed different responses to treatments and seasons.

Summary: Soil extracellular enzymes play a crucial role in soil nutrient cycling and microbial functions. This study investigated the effects of simulated nitrogen deposition and phosphorus addition on the activity and stoichiometry of soil extracellular enzymes in Chinese fir forests. The results showed that nitrogen addition had contrasting effects on different soil enzymes, while phosphorus addition aggravated carbon limitation. The combined addition of nitrogen and phosphorus significantly influenced soil extracellular enzyme activity and stoichiometry, indicating the importance of soil characteristics in microbial resource acquisition strategies. The findings provide valuable insights for the management of Chinese fir forests under increasing nitrogen deposition scenarios.

Summary: Our current knowledge regarding the impact of nitrogen availability on the year-to-year fluctuations in seed production patterns of perennial plants is limited. However, a multiyear field experiment was conducted to investigate these effects, and the results suggest that augmenting the nitrogen content in the soil may have the capacity to modify the inherent variability in seed production and enhance reproductive efficiency. These findings have the potential to enhance our comprehension of the impact of nitrogen addition on the reproductive performance of perennial herbaceous plants and the underlying mechanisms of biodiversity.

Summary: There is a trade-off between seed yield and lodging resistance in canola under certain conditions. A split-N application strategy with moderate N rates can be recommended for canola production, and non-destructive techniques such as root electrical measurements and NDVI mapping can be used to predict lodging susceptibility and guide N fertilizer management.

Summary: Nitrogen and phosphorus are important nutrients for plant growth, and soil alkalization is a major obstacle to sustainable agriculture. Alfalfa has strong tolerance to saline-alkali and can be used for the comprehensive improvement of such land. The study on alfalfa rhizosphere and non-rhizosphere soil properties in alkaline soils is significant for land utilization, ecological improvement, and food security.

Summary: Optimizing gut health through super-dosing multienzymes in broilers can improve nutrient digestibility, maintain a diverse microbial population, and enhance overall villi morphology. Unique bacteria were found to be associated with super-dosing multienzymes, while bone mineralization was not affected. Super-dosing feed enzymes, particularly at a rate of 700 g/t, is recommended to improve gut morphology, nutrient digestibility, and promote unique microbes for feed efficiency.

Summary: Antimicrobial growth promoters (AGPs) have been widely used in the animal production industry, leading to the transfer of antibiotic-resistant bacteria to humans. Efficiently raising broiler chickens without antibiotics is a challenge, with probiotics showing potential as an effective nutritional alternative. Probiotics, especially when added to water, may improve production performance and reduce resistant bacteria in broiler chickens.
