Fig. 7

Diagrammatic representation of fresh perennial ryegrass carbohydrate breakdown over incubation time within the rumen. The diagram illustrates only the dominant carbohydrate-active enzymes (CAZymes, also known as glycosyl hydrolases (GH)).GH family numbers are shown by the numbers in the symbol key. Taxonomic origins of the expressed CAZymes are also shown in the key next to the corresponding symbol. The number of GH symbols between primary (< 4 h) and secondary (> 4 h) colonisation sub-microbiomes are representative of whether expression has increased or remained constant
