Expression of genes encoding enzymes in the cysteine and methionine metabolism and sulfate metabolism pathways. A Enzymes and intermediates involved in the cysteine and methionine metabolic pathway and that of sulfate. B Differentially expressed genes that are marked in red in metabolic pathways. Asterisk indicates a significant difference in relative gene abundance between the two breeds, where significant differences between the means were determined with Tukey’s test. Differences were considered significant at P < 0.05
