Fig 3.
Infographic summarizing the three study breeding farms (A, B, C). A) Histogram of age of mares in years. Dashed vertical line is the mean. B) Proportion of sex of offspring for each farm, values are total/count. Left side (darker) are female offspring and right side are male. C) Boxplot showing distribution of the number of the days in milk (DIM). D) Dotplot of the birth number (e.g., total number of offspring the mare has had) for each farm, with each dot representing a single mare.

Principal Component Analysis (PCA) of macronutrient (ash, fat, lactose protein) profiles of Chilean Corralero horse milk (collected from the breeding farms A, B and C) alongside examples of milk from other mares and species taken from the literature. The gray oval is a 95% confidence ellipse for Chilean Corralero horse milk. Yellow points with letters represent examples of mare’s milk from the literature, breeds as follows: A: Halfinger [30], B: Mongolian [31], C: Przewalski [32], D: Murgese [33], E: American Quarter [30], F: Italian Saddle [34], G: Halfinger [35], H: Konik [36], J: Pony [32], K: Polish Coldblood [37], L: Unspecified [1]. Black points represent milk from other species: Ass [32], Bactrian Camel [38], Buffalo [38], Cow [38], Donkey [38], Dromedary Camel [38], Gayal [38], Goat [39], Human [39], Llama [38], Mountain Zebra [32], Musk Ox [38], Plains Zebra [32], Sheep [39], Yak [38].
