Figure 2: Dendrogram generated by agglomerative hierarchical clustering (A) and parallel coordinate plots (B) highlighting the boar characteristics and artificial insemination practices of local boar operators in cluster 1 (black) and cluster 2 (green) of five different clusters. Cluster 1 boars are characterized by boar age of >3 years (yr), crossbreed, no gloves used during collection, collection of the entire ejaculate, >7 min ejaculation time, no cutting of preputial hairs, and collection frequency of >3 times/week (wk), among others. Cluster 2 boars share almost similar characteristics except for a lesser collection frequency (once/week), purebreed (Landrace), and a lower CFU/mL.
