Summary: The study aimed to determine enteric methane emissions from lactating cows grazing in cultivated and native pasture systems in the high Andes of Peru. Results showed that cows in the cultivated pasture system had lower methane emissions per unit of organic matter intake compared to those in the native pasture system. Despite some differences in organic matter digestibility, no significant variations were observed in methane yield or methane conversion factor across different systems and seasons. The intensity of methane emission per unit of energy corrected milk yield varied between systems and seasons, with higher emissions in the native pasture system during the rainy season.

Summary: Feed additives, chemical inhibitors, and biological approaches have been studied for inhibiting enteric methane production in ruminants, with limited information on the potential of micromineral supplements. This study evaluated the effect of supplemental Cu at 40 mg/kg dietary dry matter on nutrient digestion and enteric CH4 emissions in Holstein bulls, finding that it did not impair nutrient digestibility and tended to decrease CH4 emissions by 23%.

Summary: This study evaluated the impact of different fiber content diets on methane emissions from beef steers and compared different models for predicting these emissions. The results showed that a moderate fiber diet improved performance and reduced the intensity of methane emissions. The IPCC 2006 model had the best accuracy and precision.

Summary: This study used farm systems modelling to investigate ammonia volatilisation-induced nitrogen losses in different dairy farming systems across Australia. Results showed that ammonia volatilisation varied significantly across seasons and nitrogen sources, with higher levels observed in Spring. By substituting low protein maize silage, overall diet nitrogen concentration was reduced, resulting in a significant decrease in volatilisation and improvement in whole farm nitrogen use efficiency.

Summary: This paper comprehensively reviews the recent progress in SF6 emission reduction approaches. The use and emission of SF6 are still on the rise, mainly concentrated in the power industry. Restrictive use and emission reduction policies are not well promoted in developing economies. More specific policies and regulations are needed, along with accurate assessments of SF6 atmospheric properties and emissions.

Summary: This paper reports a new oxidative fluorination reagent consisting of an SF5- anion and a chemically inert phosphonium cation, which is thermally stable. Using this reagent, the SeF5- and TeF5- anions were successfully generated and tetrafluoro(phenyl)-lambda(5)-selenate and -tellurate were synthesized. Furthermore, further derivatization of the tetrafluoro(phenyl)-lambda(5)-tellurate allowed the introduction of functional groups into organic molecules.

Summary: The packing of molecular crystals is primarily controlled by weak London dispersion forces, which bring the molecular units into proximity to stabilize the system. This paper demonstrates that the same effect can be induced by external pressure. The minimal pressure required to accurately describe the crystal structure without LD interactions serves as a quantifiable measure for the weak intermolecular interactions. LD forces are shown to be essential for an accurate description of pressure-induced phase transitions across various types of molecules.

Summary: The study indicates that controlling the cadmium content in phosphorus fertilizers can effectively reduce the concentration of cadmium in soil. The leaching of cadmium in soil is influenced by the frequency of irrigation, with an increase in irrigation frequency leading to a higher cadmium leaching rate. Estimations using a mass balance approach suggest an annual cadmium leaching rate of around 1.8 g per hectare.

Summary: This study investigates the structural stability and thermodynamic degradation probabilities of selected fluorocarbon compounds as alternative insulating gases. It reveals that these compounds are suitable insulation candidates under vacuum conditions, but the presence of specific impurity gases may compromise their stability.

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: The peri-partum processes can exert various stresses on cows, but there is limited evidence on the effects of calving events on cows' immune status and reproductive health. In this study, crossbred recipient beef heifers carrying purebred Simmental embryos were observed, and it was found that induction of calving had no negative effects on dystocia or calf weight gain, but it could have a positive effect on colostral IgG concentration. Blood calcium concentrations were associated with subsequent uterine health, and immune function-related cytokines showed temporal changes during the peri- and post-partum period.

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.
