Number of mares: 𝑁 D : dominants, 𝑁 S : subordinates, 𝑁 B : barren, and 𝑁 F : with foals; r: received from the stallion, g: given to the stallion; * 𝑃 < . 0 5 . Time as associate and as nearest neighbour are expressed as proportions. Frequencies of approaches is measured in number of occurrences per hour.
