Agricultural methane emissions strongly contribute to global greenhouse gas production. Under these circumstances, meeting international climate goals, including the Global Methane Pledge or the European Green Deal, requires developing targeted mitigation strategies. However, research using advanced clustering techniques in a multilevel context remains scarce and mostly limited to CO2 emissions. This lack of time-series studies addressing regional variability hinders efforts to develop effective mitigation strategies. This study addresses three main research questions: (i) What are the main trends in agricultural methane emissions...

Mastitis is a complex, common and economically problematic issue in dairy cattle production. In this study, breast cancer 1 (BRCA1) and toll-like receptor 1 (TLR1) genes were taken as candidate genes for mastitis resistance. This study investigated whether BRCA1 and TLR1 genes were associated with milk production traits (daily milk yield, fat, and protein content) and somatic cell score (SCS). A total of 105 cows (25 Holstein, 48 Simmental, and 32 crossbred Holstein) were genotyped using the PCR-RFLP method. Cows with the BRCA1 c.46126G>T GG genotype had significantly lower SCS than the other genotypes....

The experiment was done on 180 (2 × 90) Cherry Valley ducks that were fattened until 42 days of age with parity of females and males in the group. The aim of the study was to examine the effect of substituting dehulled lupin seed meal, Zulika variety, for soybean meal and its impact on the fatty acid content of breast and thigh muscle fat. Feeding lupin diets resulted in a significant (P ≤ 0.05) increase in monounsaturated fatty acids (MUFA) in Cherry Valley ducks, as well as significant (P ≤ 0.05) increase in polyunsaturated fatty acids n-3 (PUFA n-3) in breast and thigh muscle fat. There was no effect of the tested...

This study evaluated the effects of feeding European seabass (Dicentrarchus labrax) that developed from the fingerling to juvenile stage a diet supplemented with a blend of Padina sp. and GroBiotic®-A over a 12-week period. A total of 480 fish (initial weight: 2.08 ± 0.06 g) were randomly allocated to four groups, each comprising three replicates. The fish were fed to satiation with diets containing varying proportions of Padina sp. and GroBiotic®-A: 0% Padina sp. and 0% GroBiotic®-A (0P0G), 1% Padina sp. and 1% GroBiotic®-A (1P1G), 2% Padina sp....
