Summary: The effects of different ruminal protozoa on methane emissions from ruminants were evaluated in a meta-analysis. It was found that isotrichids were positively associated with methane emissions, while entodiniomorphids were not. Reductions in total protozoa and isotrichid concentrations were observed to decrease methane emissions. The isotrichid methane prediction model was more reliable than the total protozoa model.

Summary: The study demonstrates that organic nitrogen has a significant impact on CO2 and N2O emissions, and slightly stimulates CH4 uptake. The effects of nitrogen composition on CO2 emissions and CH4 uptake are independent of input rates and measurement dates, but show stronger responses to N2O emissions. This suggests that N fertilizer management can help mitigate greenhouse gas emissions.

Summary: This study evaluated the energy consumption and greenhouse gas (GHG) emissions of an integrated multi-product biorefinery and compared different pathways and configurations. The results showed that the emission intensity of biorefinery products is lower than fossil energy products but higher than dedicated bioenergy technologies. Reducing feedstock moisture content and increasing ethanol concentration can significantly reduce emissions.

Summary: This study analyzed the effects of grasses, legume, and alfalfa-grass mixtures on greenhouse gas emissions, net global warming potential, yield-based greenhouse gas intensity, soil chemical properties, and forage productivity. The results demonstrated that alfalfa-grass mixtures significantly improved forage productivity and reduced greenhouse gas emissions compared to monocultures.

Summary: The study evaluated the impact of different nitrogen fertilizer formulations and rates on nitrous oxide emissions in temperate grassland, finding that fertilizer choice and rate can affect nitrous oxide losses. Urea showed the highest sensitivity to nitrogen rate, followed by CAN and urea+NBPT showing the least sensitivity.

Summary: Experimental studies showed that applying cattle manure fed with 3-NOP to soil significantly affects soil GHG emissions, with lower N2O emissions; composting can reduce soil GHG emissions, but it also releases GHGs; further research is needed to assess the impact of soil properties in field studies.

Summary: The study found that adding chitosan and different levels of crude protein to beef cattle feed can affect nutrient intake, digestion, and nitrogen excretion. Chitosan can reduce nutrient digestibility, while high crude protein diets increase nitrogen excretion. High crude protein diets lead to increased nitrogen excretion in urine, while chitosan inclusion increases nitrogen excretion in feces.

Summary: This study investigated the effects of ewe maternal genetic merit and country of origin on lamb growth and performance pre- and post-weaning. The results showed that lambs from New Zealand had higher weights, average daily gains, and muscle depths compared to Irish lambs. The maternal genetic merit also influenced lamb performance.

Summary: This study compares the performance of machine learning algorithm random forest (RF) and multiple linear regression (MLR) models in predicting methane emissions from dairy cows. The results show that RF models outperform MLR models in accuracy when dry matter intake (DMI) is included in the model. Imputing missing data points improves prediction accuracy.

Summary: This study aimed to predict nitrogen excretion in feces and urine of lactating dairy cows by collecting data from different continents. The study found that simple models based on dry matter intake or nitrogen intake performed well in predicting fecal nitrogen excretion, while simple models based on milk urea nitrogen and nitrogen intake performed better in predicting urinary nitrogen excretion. In the absence of intake data, complex equations using easily measured variables can be used to predict fecal, urinary, or total manure nitrogen excretion, but these equations have lower performance.
