The evaluation of climate plasticity and content of free amino acids, sugars and fatty acids in Bulgarian soybean cultivars were used as an innovative approach. The field performance, expression and metabolomic profiles of leaves, green seeds and mature seeds of plants grown from low temperature pre-treated and not-treated seeds were assessed by real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) and gas chromatography/mass spectrometry (GC/MS). The data from the morphological indicators, expression profiles and content of metabolites confirmed that the plants grown from low temperature pre-treated seeds had better performance. The expression profiles correlated with the content of amino acids and sugars. Inclusion of extruded full-fat soybean from cvs. Srebrina and Richy in the compound feed for pigs and soybean cake obtained after cold pressed soybeans of cv. Srebrina in compound feed for laying hens were investigated. The results confirmed that extruded full-fat soybean cv. Srebrina could be successfully included in the protein component of feed for growing pigs at a rate of 50% of soybean meal in protein equivalent. Extruded full-fat soybean cv. Richy in the amount of 30% of the protein component of the ration, in protein equivalent of the compound feed for the period of fattening of pigs could be included. The results confirmed that feed for laying hens, in which 50% of imported soybean meal is replaced by soybean cake produced from locally grown soybean, could increase the content of free amino and fatty acids of the final product and benefit the quality of eggs.

About 57 percent of the soybeans imported by the UK for animal feed comes from Brazil. However, Brazilian soybean production is one of the drivers of the Amazon's deforestation, which has increased significantly sincte 2019. Cecar Revoredo-Giha and Montserrat Costa-Font discuss the options for the UK to make its livestock production sustainable.

Among legume crops, forage peas and field beans show the most symptoms of legume fatigue. This is due to infestation with Didymella, Fusarium, Aphanomyces and other root rot pathogens as a result of over-cultivation of peas or other legumes such as lupines, field beans, vetches, red clover or lucerne. A heavy infestation may lead to a total loss of the peas or beans. The method in this practice abstract offers reference points regarding the soil contamination with the above-mentioned pathogens, and thus indication for a possibly required cultivation break. Refraining from cultivating on contaminated soils helps avoid high yield loss due to legume fatigue.
