Fig. 3From: Model-based exploration of the impact of glucose metabolism on the estrous cycle dynamics in dairy cowsChanges in P4 and IGF-1 levels during the estrous cycle. Growth of P4 (a) is correlated to the decay of IGF-1 (b). Data of IGF-1 and P4 from 13 Holstein dairy cows (red dots) were collected and kindly provided by Kawashima et al. [59]Back to article page
