Selective attention in dairy cattle [PDF]
Behavioural Processes, 2016 In a replication of Reynolds (1961), two cows learned to discriminate between compound stimuli in a forced choice procedure where pushing through a one-way gate marked with a red cross (S+) gave access to food. Pushing through a one-way gate marked with a yellow triangle (S-) gave no access to food.

Estimating test-day milk yields by modeling proportional daily yields: Going beyond linearity
Journal of Dairy Science, 2023 : In the United States, lactation milk yields are not measured directly but are calculated from the test-day milk yields. Still, test-day milk yields are estimated from partial yields obtained from single milkings.
